Hi,
I have an issue with the way 2.1 roms handle background processes. Using Cronos 1.4.1 at the moment but the issue is the same in every 2.1 rom I've tried. The issue is not there in 1.5 roms.
In the car I like to run Spotify and CoPilot at the same with Spotify in the background over A2DP. When I do this the music from Spotify starts breaking up and becomes unlistenable. I can fix this by turning off the screen but it starts again when the screen is turned back on. CoPilot isn't a huge amount of good without a screen so this is a pretty bad workaround. I wouldn't complain and just chalk it up to underpowered hardware but I never had this problem with the 1.5 roms.
I've tried overclocking but that doesnt help at all. At a guess I would say that the scheduler is effectively choking Spotify when it's got a another app in the foreground (it isn't just CoPilot that deprives Spotify but most programs that have constantly running processes i.e. games). Web browsing only breaks up the music during page loads.
Is there a way of telling the scheduler to give Spotify a greater or equal priority to foreground apps? Is this something that BFS will solve (or make worse). Is it possible the official kernel will make a difference?
Any help will be much appreciated.
Cheers,
Phil
PS: Apologies if this belongs in the general forum but I thought this is more of a development issue.
You can always try setting a `nice`/renice constant.
I have exactly the same issue with spotify, it seems to have very low priority, I don't know if this is a problem with the spotify app or the way in which android 2.1 deals with it but it does seem to be throttled to the point of stopping when you try and do anything else with your phone while running it.
It didn't appear to be an issue on any of the 1.5 roms and seems to be a lot worse on a Sense 2.1 rom (I don't know if that is because there are a lot more things running in the background)
I used a the "top" command within adb shell and could see that other process, some htc and some standard android were jumping up the cpu usage way higher than spotify and this seemed to cause the music to break up.
I really hope that if the official 2.1 version is released, whatever is causing the issue (sense, android or the spotify app) is fixed!
EDIT: for some reason, trying to load up web pages makes it stutter like crazy!
Hi,
adwinp: you clearly know more than I do. How would I go about setting that?
DarthOps: I'm glad that I'm not the only one that finds this frustrating. I'll check to see if the Music app behaves the same way or if it's just Spotify. If it's just Spotify then maybe it's worth raising a bug report with them. Have you tried it recently in a 1.5 rom? Wondering if the later versions of Spotify still behave fine in 1.5.
Cheers,
Phil
Hey.
I have the same issue with all 2.1 roms. I'm currently using cronos 1.4.1 and it's a bit better than with other roms.
I guess we'll have to wait for the official eclair release before raising a bug report
With 1.5 there's no problem.
I'm using app2sd, are you guys too ?
Yup, but I am pretty sure I've had the same issue using non app2sd roms. I'm trying that scheduler hack somebody put up on the forum, will post my results in a sec.
Update 1:
All the tests were done with Spotify over headphones and not A2DP. Going to test that on my way home in the car.
Spotify and Torque (OBD app that is constantly running and uses BT), saw a possible improvement in that it took a good half a minute before Spotify started breaking up but then it was as bad as before.
Spotify and CoPilot are playing nicely together in the office but the real issue is when the map updates (i.e. moving). Will test on my way home.
Spotify and web browsing: loaded bbc.co.uk and Spotify didn't stutter once.
Spotify and Frozen Bubble: No stutter at all during playing.
This could actually be a workable solution and is promising that maybe BFS based roms will work.
Could you give us some informations about how to do this hack ?

You have to edit your initrd (init.rc) and rebuild your boot.img
You have to find out the resource # of the process choking the system and reduce its nice, and upp the one being slow, for example.
The arguments of setrlimit: resource current max
Sorry, should have said. http://forum.xda-developers.com/showthread.php?t=689829 has all the details.
Turn usb debugging on and open an adb shell to type in the commands from the post above or alternatively use the gscript method (didn't work for me on Cronos 1.4.1, the SU request FC on me).
adwinp: Wow, think that might well be beyond my capabilities. Is there any way to edit that in adb? Also it's not one program being "nasty" but rather Spotify being too "nice" .
Ok thanks a lot, I'm gonna give it a try
I find that I tend to get stutters when the phone changes between 2G and 3G connections too, I remember some Droid users reporting the same problem

Change your band to WCDMA only:
open dialer, and:
*#*#4636#*#*
Be sure you have good 3G coverage in your region first!
Unfortunately the scheduler hack doesn't fix this for me. Tried it in the car going home and still got lots of stutter when running CoPilot. Possibly a bit better than before. Tried with and without A2DP and it made no difference. Back to the drawing board I guess.

Are you going to raise a bug with Spotify?
Moved as not ROM Dev.
Just tried with the official release, it's worse than with cronos droid.

Hey everyone! I'm new to the forum and just received my g tablet today. I followed the instructions for installing cwmod and tnt lite 4.40 and everything went great. However, I've run into a few issues. When trying to download angry birds it hangs at 15%. I have tried multiple times to kill the download and restart it with the same results.
I'm also new to Android. Is there a way to set things up so my gmail is not accessible to anyone who picks up my tablet? I could also use a recommendation for a good video player that plays .avi files. Another problem I'm having is that whenever I try to play a music file in either the native music player or winamp, the app crashes. Everyone told me how much better android is than apple but so far im not that impressed. Can anyone make some recommendations so I can see the full potential of this tablet? Thanks in advance!
I just upgraded from 4.2 to 4.4.0 and don't have any of the issues you are referring to. I was previously getting a couple of force closes that I don't have anymore with 4.4 which makes me happy. I just confirmed movies play, but I don't have any songs loaded to test that. Hopefully someone here with greater knowledge will chime in quickly. You made a good choice going with Android - don't give up hope. It does take a little more effort to get it setup the way you want it, but the beauty is that you HAVE a lot of choices which iOS does not allow. You'll get there, and then you will love it.

Have you tried clearing caches? Wiping data? Many times those two simple things (which are usually recommended procedure after flashing a new ROM0 will clear up all kinds of problems.
With the latest TNTL you should be able to activate the lock screen. You'll need to set up a shortcut through your launcher to a security settings screen that isn't shown by default. That will allow you to enter a password, pin or unlock pattern.
Update: Just realized camera isn't working either. As for the Angry Birds problem, I have downloaded and installed other apps with no problem but for some reason Angry Birds hangs at 15% - super frustrating! Also, is there a way to do a screen capture? Thanks in advance!
I had a similar problem
You really need to check the error code to verify. I was having a similar issue and I found an article to resolve my issue.
This worked for me but like I said you need to check if you are receiving an error when attempting to install.
I would only do what this little fixit instructs to fix

The caveat with the android over apple is the versatility and personal control over how you get to use your device. That said, it requires a little bit of effort, research, and frustration to get it all to work perfectly if you choose to use the latest builds. If you want the least amount of problems use the most stable build (which is usually not the most latest build) Once you get use to it, using the latest build with bugs won't be so intimidating and frustrating...maybe still frustrating

If the camera is not working, you definitely want to do a data wipe (this is a GTablet, correct? I ask because VEGA and Adam users have tried to use TNT Lite before, and their cameras would definitely break).
As for screen capture, I used ddms (in the Android SDK).
due to popular demand
so i installed it
and i keep resarting
there is lag from time to time. even honeycomb was faster.
is there a reason why? i did install supplement.
is it possible for ANYONE to make a single install then 2?
also is there a reason why my wifi signal is so low now. Or is it just how the new icon displays it.
first time it restarted was when i was downloading stuff from market.
then when i was playing videos on rock player
and then it completely froze when i was skipping around in a 1080 trailer
btw how come my wallpaers are scaled and cropped in launcher pro and not default launcher. i dont want to use default vega launmcher. just a personal choice. I shall contact launcherpro and see but figured if anyone knew
so i tired putting a different kernal on.
Wifi signal was improved but now drops more frequently.
also was looking into making 1 update for others.
if i just merged both zips. within 7zip would that break sign or would i need to re-sign it?
for 1080. the high profile issue answer that i was given seems to be right. but it still plays. only when i skip around in the vid does it freeze or force close
the lag has gotten better since install rom but seems much slower the non overclocked roms. dont know why.
i have tried wiping data and cache. same results.
well this rom was poorly made. Decided to switch.
I just wonder, if so many people can post hateful comments why they dont put their time to good use. oh well.
Hi,
So I just recently got the Galaxy Tab 10.1 and I have to say I'm a bit disappointed. I am familiar with Android and I know what I'm doing (or so I think lol) but some things just aren't working and I don't know if it's me or software limitation. Regardless I'm hoping someone can shedd some light on these...
1. The market is lacking a LOT of applications that are available on phones. Is that right? I thought it would just scale for the most part....I can't even find the official Facebook app on the market. Am I looking in the wrong place or something? Hulu? Netflix??
1a. Some applications that I sideload (mainly widgets) like typoclock or something of that sort....install, but when I go to add the widget it is not there, as if never installed. Even when I try to reinstall it, it says that it will replace the old one so i know for a fact that it installs, but the widgets aren't available, and they arent listed in the installed apps drawer either.
2. It seems kind of sluggish...and I really haven't installed much, even from a cold boot...it's kinda laggy, not as quick as I have seen on some review videos. Quadrant scores around 1400-1500. I Rooted it, installed the latest SunBurst ROM and overclocked to 1.4Ghz and it's still laggy often despite nearing 3000 on quadrant now.
3. So I couldn't get any Netflix apk to work on it stock, so once I rooted, installed Sunburst ROM it came installed with a Netflix app, but I don't think it's official since the icon is orange and has a little android on it. Needless to say THAT app doesn't work and CAN'T be installed (I figure it's cooked onto the ROM) regardless I found a Netflix apk that install and replaces it, and works...but after one day it reverts back to the old netflix and doesn't work. So pretty much everytime I want to use Netflix I have to reinstall and overwrite with the new Netflix apk I found...it's annoying. (and the search function doesn't work on that Netflix either)
I know it's a lot to rant about and a lot of issues, and I love the tab and honeycomb, but I can't believe these issues still persist. I hope someone can help me with one/all of these and I will be forever grateful.
Thanks, hope someone can help...
1a. Try a restart after you install a widget. It seems that if the widget is not made for HC, it doesn't appear before you restart.
i tried rebooting but that didn't help any unfortunately...
There's a netflix 1.3 APK somewhere that sideloads perfectly. I haven't tried it with Touchwiz yet - I haven't even touched Touchwiz.
Try stock ROM first. Your ROM might have broken something. I know Bonsai completely broke USB storage support as an example, and Starburst claims to be the "most complete and fastest Touchwiz experience" which means it's going to have missing and broken things. Any ROM dev making claims like that is compensating for something. The "hacked-icon" Netflix app is an obvious sign they went a LITTLE too far.
Netflix sideload works perfectly on my Tab. Unrooted. TouchWiz. Stock.
i tried netflix fix on starburst rom, it did work but reverted back to fcs after a reboot. i switched to bonsai 3, netflix seems to be working fine even after a reboot.
2. It seems kind of sluggish...
The default launcher is a bit sluggish, it is a honeycomb issue. For me I have seen after a "reboot", the tab does take a couple of minutes to "settle", then it is smooth for me, but if you have lot of widgets on your homescreens it will be sluggish, my experience in any case.
thanks to all you guys for all the replies.
As far as the Netflix, I know I do have the correct apk I think the issue is that it isn't playing nice with the one that is baked into the rom. I guess I will have to install another rom.
However I haven't heard anything on the apps, is that right? There's no Facebook? Anyoneelse having issues with Widgets not appearing?
For Facebook search for an app in the market called 'Friend Me'
Looks great and works great =)
for getting rid of sluggishness try this launcher: http://forum.xda-developers.com/showthread.php?t=1188701

Thanks! Good call, app looks great!
@js931,I'll give that launcher a try and see how it goes.
I understand and feel for you on your problems. My 3rd (and final) Galaxy Tab is on the way to me from Amazon.com. I also have an Asus Transformer on the way as well and the device that gives me the least amount of problems is the device I plan to keep. I want to like the Tab but I don't have high hopes since I'm about to be on my 3rd device. The 2nd one worked perfectly after Touchwiz for a while - even fixed issues I was having such as the typing lag - but the issues I had with the first one (screen and/or Wifi doesn't respond after bringing the device out of sleep) resurfaced a few days ago. The 2nd Tab also had something loose on the inside as it produces a loud rattling noise whenever it vibrates. While that is easily cured by turning off the vibration, I paid $600 for this device and I expect it to be near-perfect. So any little issue I have with this 3rd Tab means it's going back for a refund and I'll keep the Transformer... assuming it behaves like it should, lol.
At any rate, good luck with your issues. The Tab is a beautiful device but seems to be problematic... at least that's my experience with it.
Hey guys. I believe that the os21 update has a bad memory leak/background processing management(besides a kernal issue). When playing heavy 3d games like Nova 3 or Sonic, the framerates are really slow or stutter a lot until the games force-close. Well, for the past 2 days, I have not had this issue, both Nova 3 and Sonic play with no stuttering at all, and I have not experienced any more game crashes. My browser also seems much smoother. Please try the two fix options listed below, while noting that the 2nd option seems to work best with mass Efeect, and less "strict" on runnig processes than the first option:
Fix #1- What I did was push the soft reset button on the Prime (using a small paperclip), then waited for the Prime to reboot. Once it rebooted, DO NOT let the Prime load up anything, just immediately go into settings, developer options, select the kill all activities option, then for background processes, select "at most 1 process only" Delete all of your running task managers/task widgets an that's it. Now all of my games run, no crashes, and the framerates for Nova 3 and Sonic is MUCH better.
Fix# 2 - For those still having issues with Mass Effect, this alternate setting will definitely fix the problem. After soft rebooting, go into development settings, and then for background processes, select "at most 1 process only" and DO NOT select kill all processes after leaving them. This setting has been confirmed to fix the Mass Effect issue, as well as all other games while still keeping the Prime running a lot smoother.
Please try using the exact instructions that I have posted, and let me know if this works for you guys. If so, then it proves that the os21 has a memory management issue which is causing all the current issues we are having.
Also, I would like to share this post from Jaycustom, whom has also been using this method for a few days now and enjoying it more than myself lol. He ran a CPU test to test the differences before and after my fix. See his results below:
Default settings said I had about 19 user/ 29 system processes running.
Dev settings gave me 14 user/ 11 system processes running.
Default settings for system memory 600+mb used/300+ free
Dev settings for system memory 300+ used/600+ free
The memory usage was pretty much exactly reversed! So I assume this is where most, but not all, of the performance boost comes from. CPU usage was also lower, not by much though.
See the video that I made (link below)showing me using the default browser, which is now really fast and stable using this method. I also ran Mass Effect 3 and Nova 3 to show that I have no issues playing these games anymore. I used a Samsung Galaxy tab to record, so please re-frame from laughing at the quality of the vid lol! If you guys would like me to try more games/apps, please let me know.

Nova 3 is still freezing and crashing, frame rate is still same.... I think tehere is no solution untill FailLoft will update the app for tegra 3.

Sorry to hear that it didnt work for you, but it seems to have resolved the issue for me entirely. I am not exeriencing any more gam crashes or white flashing screens. Are you sure that you followed the stes listed? Waiting for others to rely, but either my Prime just decided to play all my games correctly, or this is "fix" is working for me.
This is not an acceptable fix, it is only a workaround.

I'll have to try this out tonight. To clarify, when you say "do not let it load up anything", do you just mean go into the settings as soon as possible and kill things? It must start running services as soon as it boots, no? I guess this just minimizes the "damage"?
Hi, I've just tried this and it doesn't seem to have had much of an effect I'm afraid.
In the last 10 mins I've still had two spontaneous browser shutdowns, plus crappy streaming video playback from sites such as bbc iplayer.
The pages seem to load a little faster and scrolling may be a touch smoother but thats about it the best I can say.
This solution works well for me. I have been doing this for some time, except I have limited the processes to three. Limiting it to one seems to improve it even better. Widgets seem also to be a drain on the resources and limiting those works well for me. Much thanks for the post.
You might also try this solution from here post #118 :

yes exactly.. this is the way it worked for me. Just immediately go into setting, and select the options that i listed. This will only allow the essential programs to run. Please let me know if this works for you. Also, switch the prime to performance for graphic heavy games. Still testing this, but so far I have not have any crashes since applying.

Thanks for confirm this. Yes, my Prime is no longer lagging when browsing or crashing during gameplay..the difference is honestly night and day. Just confirms for me that .21 is not handling the background processes, or closing them correctly.

you shouldn't have to factory reset, that would suck
Can you try the soft reset option again? Once it's done, update the setting as listed and try the Prime on performance mode. If that doesn't help, then you may have a bad app which is hogging on your resources and causing the slowdown/crashes.
This procedure also seems to improve on the strength of the Wi-Fi signal. At least on mine it does.

Maybe it's just because the Prime is loading pages a lot faster because there aren't so many things running in the background now. it would be cool though if this also fixed wifi, maybe someone should do a speed test for before and after the fix?
I just tried the default browser again. It does not lag/stutter when scrolling through the pages anywhere near like it used to. it's not as smooth as opera mini, but it's a LOT better than before. Still no game crashes at all since doing this. I can post vids for anyone who would like to see proof after work.

I was gonna do one anyway, just to start from scratch with a blank slate and get it set up how I want it!
After resetting, and before any apps are downloaded the browser is working much much better once the settings you recommend are applied. Loading and scrolling is faster and there have been no force closes or video hangups.
Cheers, I look forward to this .28 update but thats helped me out a lot in the meantime!

Great to hear! yes, my Prime seems much quicker with touch inputs, scrolling, gaming and web browsing. Must of been a bad memory issue along with the kernel for .21.
just did this ans seems to work very well. i was getting around 12-15mbs and now im getting 32mbs in the garage with only 1 bar. im very happy with that. thanks for sharing.
