Java - Ubuntu Touch Q&A, Help & Troubleshooting

Has anyone had any luck installing Java? I tried a few feeble attempts, but find that /usr/ is read only and my linux skills are so rusty that I didn't want to smash my head trying to remember it all if people have already smashed their head on that wall before me.

Installing Linux

Hi All
Just arrived at this place after doing a Google search. To be honest I am not sure what I want to do with this phone! I got given it by a mate who thought I might like to play with it! It has a couple of scratches in the screen!
Anyway, I thought I would have a go at installing Linux on the device. But after reading various bits I am not any the wiser! I generally use a Mac but I do have an Ubuntu box and access to an xp box. What I would like to do is install linux as an os on the XDA II. What are the links to do this please? I have never done anything like this, so I'll be walking in the dark, is ti going to be possible? Or do I need a degree in technical stuff?
Any help would be much appreciated or maybe there is someone in the uk who has a better idea of what to do with this phone!
Thanks.

Complete noob to Linux

Hi
I'm completely new to linux but I'd like to have a go at editing ROMs basically I need someone to give me a complete idiots guide on what i need to download and where to begin.
Any pointers would be great.
Cheers
Please use the search function before posting. You will find the answers to most of your questions that way, as they've often been asked before.
http://developer.android.com/sdk/1.6_r1/index.html
Thanks for the link and I have already searched the forums but I don't want to develop an application and I've already downloaded the SDK. I found This but didn't really understand it. I was hoping someone might be kind enough to walk me through where to begin.
figure it out yourself, it's not teachable ..
Yeah ok...
Thanks for the help
boy i sure am glad that some people were born knowing everything. look markspark i'm in the same boat as you, trying to figure this stuff out but some people decide they would rather be rude, if i knew how to do it i would do my best to point you in the right direction but then again i'm not full of myself.
best of luck to you my friend and if i figure it out i'll make a post on how to build an android rom and then make some youtube videos or something, but like i said i'm not full of myself.

[Q] Point me to the kitchen?

Howdy All,
Well to cut a long story short, I have broken my leg, rather badly, to the point of minimum 6 months in a wheelchair sort of break. No big deal, it will heal, but I figure it gives me a hell of a lot of downtime, which means I may just have time to get into this cooking thing.
I've found a few guides, but they all seem to be device specific, and reccomend further reading without pointing one in the direction of where to do that reading.
Can any one point me to some resources and get me into the kitchen? Any help would be muchly appreciated!
Cheers,
JD
Really? Not one suggestion?
I'm not asking you to do the work for me, I just need a little help in which direction to head. I'm looking for documentation and resources, and after being elbow deep in google searches, the best I can find is some tool that takes a stock i9000 rom and makes it flashable.
I've been playing with roms for a long while, I've dabbled in coding both with android's bastardised java and a few other languages. I'm not here saying please hold my hand, I'm just wondering how the chefs here got started.
There seems to be a distinct lack of documentation or information to bridge the gap from never having cooked a rom to noob chef. Once I get that under my belt I will have a better idea about what I specifically need to learn more about
This is a community yeah? Surely if that's the case, there's at least some advice for someone who is interested in starting development. Give something back and all? I'm not here to take someone elses work, put some themes on top and release it as my own, I'm genuinely interested in learning more about the OS and understanding what makes these things tick.
I'm sure you all didn't fall off the toilet while hanging a clock and wake later with an understanding of the metaphorical flux capacitor that powers custom ROMS, all I am interested in is how to get started, how did you get started, what should I be reading about?
Thanks in advance for any help.

Its the post topic kitchens are in the Dev section
But you want something different to a kitchen to put together a rom you are looking to learn how to build a rom .The route is probably the XDA developers forum front page .

where do i start app development?

Basically I'm looking to.start making some apps, mainly for fun but depends how I get on.
I've had a go with the app inventor which has given me an idea of how the apps work but it seems slightly limited. I have made some of the tutorial apps and had a look around here for advice but can't find a thread.
What is the best software to use?
where is the best place to learn the code for the software or possibly a forum/thread with some tutorials?
I see a lot of people using eclipse to I'm thinking about trying this but most advice seems to be on how to set the program up.
Can anyone point me in the right direction? Sorry if there is a thread but I couldn't find it!
I would use eclipse with android plugin, I would also start as an adw themer. You can search online to get the eclipse development software on their site. The plugin can be found on the site.
http://developer.android.com/sdk/eclipse-adt.html
If you have any question during setup, I may be able to help! Feel free to send me a message!
Hope this helps!
Also you will need the sdk.

I find it easier to set up tadp (Tegra Android Development Platform) It includes Eclipse(Preconfigured with android adt plugin), SDK, NDK, cygwyn tegra profiler (for tegra devices) and lots of other tools. A sign up will be required though.
link: http://developer.nvidia.com
For Code syntax I would say basic C/C++/Java and go to http://developer.android.com
cool!
I also want to get into making apps but i guess you have to have a formal background in some sort of programming or the like?
If you are a former VB programmer or C#, then you can develop with C# and .Net
http://forum.xda-developers.com/forumdisplay.php?f=2198
Well, if you are talking about developing for android, go to androids home website. developer.android.com. That's a start. You will need to have some basic programming skills. Learning programming and android at the same time will be difficult. I use eclipse. I was more use to netbeans and even though they had a plugin for netbeans, there was no reason for me to stay with netbeans. It was an easy transition from netbeans to eclipse though. Anyway, it'll take time before things start making sense. There will be moments where you want to put your fist through your screen and moments of excitement when you've made your first penny. Take your time and develop high quality apps cause you know why? High quality apps dont fail, they always get the downloads even if there's a thousand similar apps, your app will be part of the thousand apps that get downloaded, unlike the 100 thousand apps that are similar but are of low quality.
I use java, by the way...
I dont know much you know about programming but this is what im following right now it is a little bit complicated and he doesent explain very well the base java stuff but other than thats its a great tutorial series. started watching it about 10 days ago right now im on the 100th tutorial and i dont feel like giving up yet, give it a try and see how it works out.

Yes, its a great series. But he tries to explain Java little bit on the go, but it maybe difficult or confusing for people who haven't seen Java at all, or haven't done some simple basic programs on Java. But even though, he explains it shortly as he could.
So what should be done is, follow the Oracle Java Tutorials on the side as you go through those Android tutorials. Oracle has a great documentation on Java, and its a great deal breaker to make you understand Java. Anyways a great devotion of time should be arranged for all these.
Hello All,
I am a newbie and amature android learner. It all started copule of months back. I work in healthcare industry and I see lot of potential of mobile usage in coming years and hence started to give app development a try. I am not with backgroung of computer science or having programming knowledge ut I could find this thread very interesting to start with. kudos to XDA
Hey guys, sorry to hijack this thread, but I have a quick question.
I'm currently in university studying psychology, but have the opportunity to take an introduction computer programming course that would count towards the degree and fill a requirement.
Anyways, one of the languages covered is C++. I'm just curious if this would be a first step to learn to develop android apps.
Thanks for taking the time to read.. It's greatly appreciated

once you learn a language, the others can be different for their syntax, but the logic behind is almost the same. So learn the basic of programming and you will be able to program android. C++ is similar to Java, if you want to code in Java (the best way to code for android imho)

As C++ comes under the Object Oriented Programming (OOP) concept, its still good because Java also follows the OOP concept. As for developing android apps, Java is the main language used for coding by most developers. It is said that any language could be used though, but not much clue regarding it.
In your case as a first step, learning C++ is no harm because it hooks you up into the basic programming principles and teaches you how the flow works, if you are coming from a non-computer science background.

Thank you so much for responding.
My only worry is that I have never even looked at a language, so I'm kind of intimidated by it. Would an introduction class give me the building blocks to learn more or would I need to take further courses do you think?
Thanks for taking the time

what is needed to learn programming is practicing a lot! the course can give you the right way to think as a programmer, but i think only practicing and experimenting will make you a real programmer.

So it sounds as though it would be good to take this course than. Thanks to both of you for reassuring my decision. :beer:
If anyone who reads this wants a tutorial on Java, I found a thread that has a whole class with it broken down into pieces for you to learn.

Enjoy
AND for those who have already started with the Android tutorials, here's a tip. The Eclipse Android emulator seems to be a bit slow (it may be annoying for starters like me!) Check out this link that might help:

I find its good to take a programming course even if you aren't going to program apps. Programming is basically problem solving. If you are a good problem solver you will probably be a good programmer and if your not a great problem solver taking a programming class will improve your problem solving skills.
Programming languages are like any other language you just have to learn the basics and the more advanced stuff will come easy. Its like Spanish, once you know what endings to put on the words you just need to learn the word for whatever it is you want to say. In programming once you understand how to put code together (which a basic programming class should teach you) its just learning what word to use to do what you want.

Well said, thanks.
There's also a big incentive when you do a course. When it can affect your GPA

Just wanna say thanks! Ive been reading (about halfway through) 'The Beginners Guide to Java Programming for Dummies' and just when I started to get a headache, I found this thread, and this Youtube tutorial is helping connect the dots to put it all together in my cluttered head.

Linux on managed chromebook

Hey all, recently I have been messing with my school chromebook for fun and have unblocked it. Now I'm looking for a way to force either devmode or linux beta, open to any ideas besides completely unmanaging it, thanks for your time if you have any ideas!
how much experience do you have in this type of stuff? did your school block crosh?

A little bit of experience, more a script kiddie then anything, but I have found a few methods around unblocking things ect, and no they have not blocked crosh unless something changed recently
