I have download a set of android source code, which has folders such as "bionic, bootable, build, dalvik, development, frameworks, hadware, packages, prebuilt" and so on. When I browse the whole code, wonder how "import android.preference.PreferenceActivity;" works in Settings.java(D:\android-srce\Google-source\packages\apps\Settings\src\com\android\settings\Settings.java). I guess there is a android.jar file somewhere after compilation. But how does Settings.java import PreferenceActivity correctly?? I'm a beginner in Android, please help me.
Sounds like you have downloaded the source code to the Android OS. If you want to build your own ROMS then you need to study about building the OS for a particular hardware platform. This is not trivial.
If you want to build an Android app that runs on an Android device then you want to download the SDK instead - start at Android SDK and follow your nose, buy a book, read the sample code.
There is not a lot of information how to change parts of Android. However, you can read information that is connected with the aosp tag. The first cite is source.android.com After the installation of android build system you can see video from marakana group. You'll find a lot of valuable information there.

today it's a shorter question I'd like to ask, to hear your opinions as I suppose some do this differently than others.
First of all,, I have an Android Studio project and am rather a novice on this subject of Android Development. That's why slight changes in the java or xml files could and did make my latest app unstable/ crashing.
Therefore I was asking myself wether Android Studio offers a way to backup stable builds - I could imagine this like a save-as option where you backup the working version and continue working on the the one but have a stable one backed up.
I know there's the export project function but I tried it out a couple of times and having worked on a project on the same device before, prior to reimporting a project causes an error and that's not the way I guess you should handle it in this situation.
I was looking at Google Cloud for using both version control and the option to commit new versions to the trunk and update them at a different location (different device). If that's the solution you propose, I need to look more closely into the documentation to get it up and running (set up the repository already but no clue how to commit changes/ versions).
So, long story short, what tool/ option do you prefer to have an export and a version control option unified for Android Studio?
Interested to hear and thankful for any advice on that!
There are multiple solutions,
Just find your solution/project in your file explorer and back it up, if you need it again just open the project with Android Studio. (not the most popular one)
Use a version control system like git. Link to tutorial (This is the most popular one), If u are unfamiliar with git, just google it and there are tons of examples and documentation. With git you can tag commits and after u mess up revert to the tagged commit
Git is the simpliest.
It's supported by AndroidStudio and later on you can upload your project to GitHub to access it from anywhere.
You can use it with terminal and shorcut keys, incons as well.
You also can make separate branches in order to make and test more versions parallely.
For more info take a look at: https://git-scm.com/about
and of course github: https://github.com/

I am new in developing apps for Android with Java Eclipse.
I get a simple problem: after following the procedure explained here:
http://www.tutorialspoint.com/android/android_hello_world_example.htm
I tried to push the "Finish" button to create my first app, but it doesn't work: the wizard remains open and nothing happens.
Also, I have several problems in the Demo apps, errors like:
'<>' source operator is not allowed for source level
and many more.
I guess I created problems with the configurations.
Thanks if you can help me to create my first app for Android and to load
the demos.
It is really had to tell what is the problem, but as Abdullah advised to use android studio because it is well designed to develop android applications. and most of the company's now days use android studio as there IDE preference, but still its developer's choice. Eclipse ADT plugin is buggy
I want to use Infragistics controls in my android application which i am creating in Eclipse IDE. But i cannot find a way to integrate these controls with eclipse. I have downloaded the file named NetAdvantage from
http://www.infragistics.com/products/android/
But I cannot find a way to use it in my project. When I try to install it, it installs it for Visual Studio. Can anybody please tell me some way as my application is in java not in C# or VB.NET
I assume that you are referring to the IGUANA UI toolset? In this case I suggest choosing the "Iguana UI 2012 Complete Bundle" download option on the IG Website.
IGUANA UI actually does not require installation - the toolset as well as the documentation and product samples (including sample source code) are all available in the downloaded zip.
Please let me know if this helps.
Okay here's the deal:
I want to download the full source of the MMS/SMS application that ships with Android phones. I want to be able to modify it, and add a little custom functionality to it.
I am developing using Eclipse, and I'm on Windows 7. I have noticed that there is now a Git for Windows, but I am pretty lost in it and not sure how to integrate everything with Eclipse.
Basically, I want to just get it to the point where I have all the source code visible in Eclipse and be able to see the app run JUST like the built-in texting/MMS app that is already on my phone. Then I'll know that I can modify it and proceed.
Any ideas?
Thanks!
There's a mirror of the SMS/MMS app on GitHub here. Just import that to Eclipse and customise away.
Unless you want to customize and use it only on your own phone (without publishing), this is not a good idea. This is because it uses classes that are hidden from the sdk. By default you won't even be able to build the apk via eclipse, but there is a way. The reason why this is a bad idea is that the hidden apis are not guaranteed to remain the same through different api-levels and your app can stop working with the next android update, and might also not work on previous api-levels. In-fact your app might not even work on selected phones running the same api-level.
I am having the tesseract-android-tools 1.00, please help me to use the interface TessBaseAPI.
I juss want to pass one .jpg image to an android application which is having some text as a part of image. then through this tesseract engine i want to extract those text into editable format..
please help to create this application in android...
Did you ever search in the internet for a manual? There are a lot of hints. Recently someone wrote a small tutorial.
Even it is for Ubuntu, but I think it gives you a clue how to proceed.
If not, your operating system is needed.
I tried compiling the tesseract-android-tools (tat) with Windows and Cygwin and failed. Some other succeeded. Then after I compiled the tat with the MAC OS and Terminal and succeeded, by using the NDK 5b.
So first have a closer look in the internet and then specify your question, so appropriate help can be posted.
Best wishes,
Volker
I recently used tess-two, which is a fork of tesseract android tools. Step-by-step tutorial on how to setup your development environment, and how to use the library with android, is provided at the readme section here - https://github.com/gorjanz/com-vodi-smetka.android
