(Development) Rendering Problems: Failed to load platform rendering library - Android Q&A, Help & Troubleshooting

Hey guys I'm pretty desperate here.. I tried asking this on SO but can't get anyone to help...
So when I try to view any of the xml's such as activity_main.xml, in the Design tab or the Text tab where it's supposed to render.. i get this message
"Rendering Problems
Failed to load platform rendering library"
Everything I google says to drop API levels to match the minimum level (by clicking the green Android button with the number next to it).. which I have done. I've tried making different projects with different minimum API/OS versions and I can't get past this error.
I've even downloaded EVERY API level in the SDK Manager.. from lvl 7 to 24.. and none work. I try to clean the build and then rebuild.. just nothing is working and I'm going insane. Someone please help =[

Jan 9, 2009 Updated: HomeScreen++ Configuration Application

Update 5/26/10The screen on my winmo phone broke about 2 weeks ago, and since then also one of the buttons on the front came off. I wasn't sure I wanted to continue with Windows Mobile considering their lack of support for older versions in Windows 7 phone, so I got an Android phone, a used G1. I'm not sure I'll continue to develop for Winmo.
So far I'm very impressed with what I see from the G1, but of course there are some apps missing, so my first priority will probably be to get some of my Winmo programs ported to Android. Sorry
HomeScreen++ Configuration Application
Version 0.30 Jan 9, 2009
In addition to some bug fixes, the following has been implemented:
-Creating a new file.
-Adding new elements and attributes: Items can only be chosen that are allowed according to the schema file. (However items can still be edited on the main page without validation.)
-Clicking the help button gives shows help for the chosen attribute.
-Application paths can be chosen from a filedialog box.
-Today plugins can be chosen from your registry.
-Comments can be saved as nodes with a # infront.
There are still the occassional crash of the program when saving the file, but
I have been unable to figure out the causes of the crashes. Please let me know if anyone figure out a pattern to the crashes.
Version 0.20 Dec. 18, 2008
This version includes the schema file, and will list the possible attributes and values for the different elements.
I have also included Attributes.xml, a file that in xml format describes all the elements, attributes and values.
My ultimate goal is to make the editing based on the schema file directly, and not via a text box.
However, programming has been slow due to computer breakdown and Christmas preparations. Maybe next year!
But if someone has any ideas/wishes how to proceed further, please let me know.
I'm still working on having comments included, and as far as I know, the program will read a file with
comments, but will crash if trying to save, so be careful.
Version 0.10 11/24/08
I got tired of editing the xml settings file for Homescreen++ (http://forum.xda-developers.com/showthread.php?t=270751) on my phone, so I decided to make a program to simplify the process. It's possible it can be used as a general editor for xml files that only has elements and attributes (this has NOT been tested).
This is a very early version, but I thought I might post it here, to get some feedback before continuing the development.
What it does:
The app wil load a Homescreen++ settings file (.xml) into a treeview.
Items can be edited, added, copied, deleted and moved around.
Installation:
The attached file can be unzipped to any folder of your choice.
Limitations:
Make sure that the attributes are listed before the elements for the respective nodes.
Danger:
Since this is such an early version, when the program asks you to save, ALWAYS save to a new file. I also suggest saving it frequently, so you don't loose any changes, should the program crash.
I don't take any responsibility for the problems this program might cause on your device, but it seems to work for me on a smartphone running Microsoft Mobile 6.
Saying that, I've already found it to be quite time saving when changing where I want elements, heigths, widths etc.
I hope it can be useful for others too.
Future improvements:
Edit: using same screen as for adding new items
validate file against schema before saving.

thanx mate, i love HomeScreen++
good idea, I will give it a try
cool excellent idea
looks good, gonna keep an eye on this. thanks in advance.
What a superb idea !
I've give up further versions of "Battery Status" because of the complexity of skins coding (XML and syntax...)
If your tool will be able to interface settings, and why not, present them in a more friendly way, this will be a killer tool...
Congrats !
wow, it may be useful tool.
this what I was thinking of !!!
HS++ users deserve this programe.
Its a useful prog , & will lead 4 more simplisity of using it.
of course,its a long way to acheave the goal ; but; keep the hard wourk & progressing,& be sure that every HS++ lover will support your work in this idea.
good luck , & may GOD bless you.
Great App!!!
A big Thaaaaanx....!!! for this great tool.I've tested this app with not only 'HS++ xmls' but also with the 'Manila2D xmls'.And everything is working fine upto now.Once again Thank You very much...
great app! but hs++ does not work with manila2d,so...

I'll try it when possible.
Cheers
great job, I hope many good skins will come out with the help of this tool, thanks.
thankyou
very good app.
Very nice app
Bug
Thanks for the nice words!
Since there weren't many comments, I wasn't sure anyone was using it, so I stopped development on it (even though it has a lot of downloads!)
I'm also surprised noone has said anything about a bug for the tplug. I don't know if I'm the only one experiencing it, but it seems that the name of another today plugin disappears when the file is opened. If I see that people are actually using it (?), I should fix it.

[Q] Getting Screen Captures from the GTab

I have been seeking the procedures/how-to in order to do screen captures on my GTab.
I've seen (what appears to be) screen captures from GTabs, but no instructions on how to perform them. Tried the "Shootme" program but get nothing but black. Research shows the Shootme program uses the frame buffer and the Tegra units don't use that for screen display.
Has anyone figured this out or can point me into some direction?

You cannot use the screen capture apps to get them, you have to use a desktop PC and run the dev environment. Search should be your friend but if not then I can dig up something.
I've been searchin' & tryin'
As far as the desktop PC, I've been reading about using DDMS to get the screen captures. To help clarify things, I have Flash Builder 4 with the latest Android SDK installed. The GTab doesn't show up as a device on any program I use following the instructions I found.
One thread had instructions on modifying the android_winusb.inf file in the Android SDK. Problem? There is no android_winusb.inf file in the Android SDK to modify. At least in th one I downloaded & installed today. Hum.
I've been googling, searching, and I think I've actually gone through every post in every GTablet section here without finding something - or else I've just missed it.
So, any links to threads, blogs, whatever would be greatly appreciated!
The only way I know is to set up a development environment by installing a Java 6 SDK, the Android SDK, the Eclipse IDE and making some configuration tweaks.
You can find instructions on the Android Developers website here. If you get it all installed but need help with the ADB (Android Debug Bridge) configuration, read this thread in the 'G Tablet Android Development forum'.
The android_winusb.inf file is in the 'google-usb_driver' folder which will be under the Android SDK folder only if you chose to install the 'Google USB Driver' package from the 'Android SDK and AVD Manager'.

no sdk needed if you use a program called QtADB it already have the adb file (or they are avalable on their website) it has a screen capture and is a very useful manager, you just need to setup the adb drivers for tegra....i already have them if you need it
I just take pic with my phone lol
Sure do appreciate your comment regarding QtADB. Followed up on the various links and got plenty of info including downloading the file. However, you mentioned drivers: "adb drivers for tegra....i already have them if you need it." I couldn't find drivers mentioned. Sure do appreciate if you could advise as to where to get them. I have Windows 7 Professional 64bit on my Computer. I have a G-Tab with my recent download and install of VEGAn-TAB 7.0. Which, I really really like. Made my G-Tab a completely different Tablet than the silly software driven thing it was when I first got it. Anyway,thanks again. Sherwin Silverman [email protected]

Screenshot ER works. There is a thread about it in here somewhere. I bought it for ~$2 and successfully took a screen shot. No ADB needed.
EDIT: For clarity, I have only tested ScreenshotER on VT Gingerbread edition.
Screen Shot it works fine.
After the trial worked, I bought a copy.
+1 for Screenshot ER
Remember to turn off Superuser toast notification in settings so you won't have the "Screenshot ER has been granted Superuser" popup in your screencaps.

Physics Projection Calculator, Problems.

I am developing my first android app, I have been studying javascript for a few months, and have manged to get it down pretty well, along with creating some fair applications with it.
This is my first android application, and please take into account that i started it less then 5 hours ago. Ill post on this thread whenever I run into problems to hopefully get some help.
Here is my aplication currently:
(attached)
nothing actually "does anything" right now, except the button its just a XML screen and a splash screen really.
Here is a project i did in JDK which i am trying to "Mimick":
The first problem i am having right now is that the background that i am trying to put on to my application is not showing up in the XML properties "Background" under drawable. The Background is saved in all 3 of the draw able folders under rec. Whenever i try to add the background manually with code i get this error.
Failed to convert @drawable/background3 into a drawable
Couldn't resolve resource @drawable/background3

Secondly I am trying to figure out how to send the numbers entered into the "editText" objects to the main java method. I used actionListeners in java but i don;t know here. No need to explain it i would be very appreciative if someone could just point me in the right direction.

[Q] Newbie needs some help - Errors in ADB

So I just started playing around with Android, the SDK, Android Studio, and Java for that matter today. I think I am figuring things out well enough and have been able to debug some simple example applications on an emulator. Noticing how slow the emulator runs, I figured a hardware-in-the-loop would go faster and connected my Samsung Note 8. As soon as the tablet connects to the hardware debugger (as reported by 'logcat' in the 'Android DDMS' box of Android Studio), I'm getting the following two messages repeating quite rapidly (every 15-30 ms):
Code:
4966-4982/? W/SAMMLibraryCore﹕ Not AMS File(Invalid AMS End Marker)
4966-4982/? W/SAMMLibrary﹕ Error on load SAMM File Info
Googling these two messages does not yield any information. I assume this is an issue with my tablet (vs. the program I am developing), but would like conformation from someone who might know better.
Thanks!

What Android version do you recommend for me?

After looking at the Index thread, it seems as if Lollipop 5.1 is the latest version of Android that is safe for an HP Touchpad. Am I understanding this correctly?
Also, if I install that one, does it wipe out WebOS? I guess it doesn't matter if so because from what I'm reading, it's completely outdated and no longer supported. Also, I'm locked out and cannot remember the passcode anyway.
No version of Android is supported on the TouchPad, therefore there isn't a 'safe' version. You'd have most success updating to current (7.1.2+) firmwares. As a TouchPad modder, these versions are the fastest and most supported by Play Store. The initial process of installing 'moboot' for the first time can be daunting, so look into using which ever version of Android is used in jcullins' Toolbox tutorial. Once moboot and TWRP are installed, you can pretty much try whichever rom you want, as this device is near impossible to brick.
Good luck!

Try the below link which points to the updated guide on how to install Android on the HP Touchpad.
If you are a newbie on this stuff, you would be a good test on how well this guide is written and if it needs any tweaks to help people follow it with accuracy.
I mean I tested it myself, but I am a "seasoned veteran" LOL, I installed KitKat from this guide and also Nougat the version that was recommend to you. Its all there.

1) So I got it to install (Evervolv Nougat) and my feedback on the tutorial is that it's a bit of information overload. Not sure how easy it would be to simply it though.
2) I could not find a link for Boost (what is that?) or the Keyboard fix. Can you assist (assuming they can be installed retroactively)? The keyboard, for instance, works in Chrome but does not appear on the home screen when tapping the Google Search Bar.
3) And maybe this should be #1...but this Nougat seems to slow things down considerably. I tried installing the game Run Race 3D for instance and it was unplayable. Would an older Android version speed things up or am I just dealing with old hardware that can't keep up?

Hello AshleyQ,
Well along with the step by step, I added a bit of instruction. For example you said, "I could not find a link for Boost (what is that?) or the Keyboard fix." So I will add a little more "overload" of instruction for what Boost Optimized settings are, in my OP at a later date.
But as per your performance. The reason its slow is because you did not load the following ZIP's in the exact sequence the instructions say. I realize its because you could not find the links for boost and keyboard. If you go to HP_TOUCHPAD's "Master List of ZIPs" in the OP of the guide, or I put it below for convenience, you will see the green list below for Nougat 7.1.2, and find the links you were missing earlier.
https://forum.xda-developers.com/hp-touchpad/general/hp-touchpad-optimize-android-swap-t3901773
and once you click link, hit "page down" 3 times and it will get you to the "Master List of Zips"
Evervolv 7.1.2 Android Nougat
1.Click Here to Download the ROM
2.Click Here to Download the Boost Optimized settings with preset CPU Frequency
3.Click here to download Google Open Apps
Select Platform ARM, Android 7.1 and the Variant you want, Pico is recommended
4.Click Here to Download the Keyboard Fix
As per the Boost Settings always start with 1728, and after that is working good, you can try to flash a higher frequency for speed, and you don't have to re-flash everything just the Boost Zip ( like 1782, or 1836 ) file from TWRP recovery. If it freezes screen just go back and flash lower frequency.
So click each link in the OP, and download the said 4 ZIP files, and follow the Original Post again, with these 4 ZIP's ready to go!!! Do not do this retroactively, but start again from scratch.
And you will be able to play the "Run Race 3D" game!!
Look at this link below, a non-gamer like user HP_TOUCHPAD from Florida, played the game Hearthstone!!! I believe you will be able to play "Run Race 3D", but we would love to hear how your results go, and we will be here to help you get a smooth running touchpad that is 100% Android, with SWAP!!!

Using these downloads from your Master List of Zips, and running my install method.
AshleyQ the OP'er wants to play Run Race 3D game. Now I am not a gamer at all, but you tried with Hearthstone so I will try now, when I download Run Race 3D game I get the attached errors. But I can run YouTube fine, everything seems fine until I run that game ( Run Race 3D ). What are these errors telling you? I waited till SWAP was over 400 Mb, and I used various boost files, first 1782, 1836 and 1728, but with no luck.
I should point out that I had about 10 minutes where I was running the game with smoothness and doing the jumps and winning the races, but then HP Touchpad started to get sluggish with little mini freezes and it threw my timing of the jumps off and I started to lose, then the error came.

In the Developers options --.>> Running Services shows Device Memory been use but does not show the swap.
The FREE in gray color shows the available free RAM, but is not the size of the swap file, for example the system can report 485 MB Free RAM and only use 60 MB of swap.
The best way to see how much swap is been use is by connecting the Tablet to PC using usb, open a terminal window and using adb shell then type
free -h
I should point out that I had about 10 minutes where I was running the game with smoothness and doing the jumps and winning the races, but then HP Touchpad started to get sluggish with little mini freezes and it threw my timing of the jumps off and I started to lose, then the error came.
Keep in mind that the free version of this game have Ads, that is a service that is running in the background and when is time to display the ads is another process getting activated. Android is constantly launching background process it does not seem to care if the device is been use, it will take priority.

The reason that I mentioned to wait until it shows 400 MB of free RAM (is not swap) is that Android finishes launching all process and the system is finally "IDLE", it takes that long for Android to finally settle and the Tablet ready to be use..
I just installed the Game, it only took about 73 MB of swap space, but I am testing on DU 9 using completely different settings. I am not a gamer, but it looks very simple, graphics are minimal, it does shows a lot of ads and even launching the Play store to install more games. The issues that I am having is that there is no minimal specification for any App, it only shows the Android version and it will depend on the Device. It will help if an App shows the minimal RAM requirement to run, then the settings can be apply to provide that amount, but is all about guessing. I am not done testing my next settings, I will use this game as a tester.
I applied some settings and tried the game and I won! is very easy to play on the Tablet with a bigger screen but it could be a real challenge on smartphone.
Attached is the screenshot of my victory.
Is work in progress, but the game should play with no issues once I finish the settings.
So what do you guys recommend that I do? I just used Run Race 3d as an example of the sluggishness and really just want an Android version and setup that will give me the best overall (meaning fastest) performance...with games/browsing/etc.

Congratulations on the RR3D win! I won a few times myself and the man did a little dance on the screen, but then my HPTP got sluggish and I kept crashing into the walls because when I pressed the screen the man would not jump like I told it too. In fact my setup got to the point I could not even take a screenshot it was too sluggish.
But if @ashleyquicik is reading this, please be patient it seems like HP_TOUCHPAD is working on some Universal performance settings that will work for all ROMs, past present and future. In the meantime you could load JC Sullins KitKat 4.4 ROM you will find that link in the 2nd Master List of zips ( RolandD's ) on below install method. I find for YouTube and Podcast apps this current version of Nougat is fine, but once I start playing "Run Race 3D" it gets sluggish. Be sure to follow directions in flashing the ZIP's in order.
HP_TOUCHPAD is now using the Run Race 3D game as a testing app, so you can be sure sooner or later this game will be working, not to win at the game, but to win and beat the sluggishness!!
This is the classic case of MAN vs. MACHINE!!!

After the first stage of the game was over and I selected to play again, then what seems to be an Advertisement came up, but it was only a black screen, then the image show trying to trick me on touching to install another game, there was no way of getting out of it, then the Play store got launch by itself and then I had to close both. There is a difference when you the user open many apps and place them on the background and when two apps are running at same time, is too much to ask for a 1GB RAM device.

I will provide the settings but I do not want to send the wrong signal as it will allow for any apps, specially games to play. Android's apps are extremely buggy even on the stock devices, just search for an issue and you will find how many users are experiencing the problem and none are related to the HP TP, just regular devices.
HP_TOUCHPAD is now using the Run Race 3D game as a testing app, so you can be sure sooner or later this game will be working, not to win at the game, but to win and beat the sluggishness!!
As you have tested yourself the game will play, you won. It is a very basic game with low graphics., but it provides HUGE Ads and also any other apps that you have installed on the Tablet will impact performance. The sluggishness comes as background services that becomes active, that is why as soon as you connect the Tablet to WiFi, it will slow down, just check Running Services and you see them all, opening and closing plus the google apps updates, it will happen even if the CPU is at full capacity and low ram available, is the way Android works.
This is the classic case of MAN vs. MACHINE!!!
I will call it MAN vs Google!
Here is the explanation for that, I will try to keep it short.

Android Apps are written in Java, Google does not want to pay license feeds as is offering the OS for free and making revenue on the data it collect from the devices for Ads placement, each device is a Digital Billboard that Google charge for displaying time to companies promoting their services or products.
If you have experience running a Virtual Machine on the Desktop, then it should be easy to understand the concept. Android apps are running inside an open source virtual machine " Dalvik" to run the java code and be display on the screen. To virtualize an OS on the desktop if the PC has 6 GB of RAM, and the guess OS requires a minimum of 4 GB to run, then it must be configure and there will only be 2GB left on the Host OS. Then the speed will degrade for low RAM resources and the HOST can not be use for nothing else. Once the Guess OS has done its job, it can be close down and the Host OS will function normally. But if the correct amount of RAM is not allocated to the Guess it will not boot, or shutdown. That is the same that happen in HP TP with Android, and those settings are apply manually in the build.prop by the manufacture. Everything in Android must be configure manually as the OS is too basic and primitive all settings are device specific according to screen resolution, size and amount of RAM ( Memory ).
Hopefully I explained it or compare it, easy to understand.

Everything in Android must be configure manually as the OS is too basic and primitive all settings are device specific according to screen resolution, size and amount of RAM ( Memory ).
Hopefully I explained it or compare it, easy to understand.

So having said that...and to sort of reiterate some of what I wrote in my last post, what is arguably the best ROM/procedure to have the best overall performance?

It all depends of the intended use from the user.
Does it needs to have a working:
Bluetooth ?
Reliable WiFi ?
Camera ?
Android compatibility with a special App ?
Android Versions are different and that sets the ROM apart, it will not be comparing Apples to Apples from different versions.
If you check my guide I have optimized 7.1.2, 8.1 and 9 to use swap and all those three versions works very similar.
One of the reason that I will be doing an Universal Setting and retro-fit older ROM, is to show that the Tablet will work similar with different ROMs.
I should probably make a version that is completely optimized only for games, that will required to delete unnecessary Android system process and RAM could be about 600 MB Free.
Does it needs to have a working:
Bluetooth ? Yes
Reliable WiFi ? YES
Camera ? Yes
Games really aren't necessary because I'm giving this tablet to someone that won't be gaming.

I started reading your thread from the beginning as I though that it was all about the 3d racer game.
You have a Tablet that would like to give to someone that has WebOS installed and also another Android version on it, which is 7.1.2 and you found it to be slow.
My recommendations for a newest ROM is the same as everyone on here recommended Evervolv 7.1.2 Android Nougat. You could use older ROMs but some basic apps may not work.
Previously @DoubleStuff provided the information on how to installed Evervolv 7.1.2 and also provided the link to my guide that with instructions.
If you flashed the Automatic_Wipe_All, then the Tablet is 100 % Android with swap and WebOS is gone, which will provide more storage space on the Tablet.
As per my guide the proper way to flash all the zip files provided is as follow:
Evervolv 7.1.2 Android Nougat
1.Click Here to Download the ROM
2.Click Here to Download the Boost Optimized settings with preset CPU Frequency
3.Click here to download Google Open Apps
Select Platform ARM, Android 7.1 and the Variant you want, Pico is recommended
4.Click Here to Download the Keyboard Fix​
The Boost optimized settings link (2) will give you the option to download 5 different CPU frequency, start with 1728 after you set up the tablet then try a higher speed, the fastest is 1836, if the Tablet boot into Android after flashing 1836 and use some apps and does not freeze then keep using it, if it reboots or freeze then flash 1782 if still not stable keep flashing lower frequencies.
To have a properly working camera, install this app:

If you have any issues just ask.

Well as I talked about in another thread where HP_TOUCHPAD wants to start retrofitting old ROM's with SWAP and Universal boost settings, there is a ROM that most agree is the "greatest ROM of all time", but its an old version of Android called KitKat 4.4.4 by JC Sullins and you can find the link here:
https://forum.xda-developers.com/showthread.php?t=2712680
Now one version later Lollipop 5.1 ( or 12.1 CM ) this same developer JC Sullins created a Lollipop ROM, that HP_TOUCHPAD is working on retrofitting: As @HP_TOUCHPAD said in a previous thread about this retrofit.
"...I Applied all optimization to CM 12.1, but testing. The only problem that I am experiencing is if I open about 8 to 9 apps and then press the square, next to home, it will reboot. I do not know if is the ROM or my settings.
But overall works great with swap. Will be posting new optimized settings, soon...." -HP_TOUCHPAD
And if I am not mistaken he may have finished it, but its not posted yet in his MASTER ZIP's list
What I recommend you do AshelyQ because its so easy and quick to install ROMs with our install methods, I would install KitKat above and test it for a day or two, then install another one maybe 7.1.2 and again test it, and maybe even another. And then you can pick the one you think meets you or your friends needs the best and stick with that ROM.
I am going to install HP_TOUCHPAD's retrofitted Lollipop ROM ( when HP_TOUCHPAD posts the settings ) and try to run "Run Race 3D" on it....I will report back with my findings.

Hmm ... I still get critical camera errors, even with the Open Camera app, even after a couple of reboots.

The stock camera App of 7.1.2 works, but colors and orientation shows incorrectly, but it works on Open Camera.

Well I have not tested JC Sullins Lollipop ROM with Universal settings yet, but I just installed JC Sullins 4.4 without swap or any special settings, just the ROM and the GApps, and I am happy to report the "Run Race 3d" game went well, I made it to the BONUS Level and earned 146 coins with lots pomp and circumstance, and was getting adds everytime I completed a race, but I waited 5 seconds then pressed the "X" and things went well. So now I am very curious how these old "great" Android versions will work with HP TOUCHPAD'S Universal settings.
3 days ago I was not a gamer, but I guess I am now!!! LOL The HP Touchpad even had enough memory to take a screen shot.
