Android Library project building jar with resources using ant

Android project referencing to multiple libraries, with resource files.
I want to generate a jar with resource files from the library project and want to use it in
main android project, am not using eclipse, I want this to be done through ant .
Is it possible, because I checked few sites, where they have given to delete the src
and distributing it as zip.
If its possible please give me the process how to go with building through ant.

As far I know this is not possible. Android does not package xml files or drawables in jar files and you cannot access them from another project. You could look at *.aar files, which were introduced last year. But it only works with the Gradle system and Android Studio. It can contain xml and drawable resources from your project.

Use already developed android project [with its resources(xml, images, layout)] into another project directly as .xyz file

I have read lots of questions on this site and come to the decision that if you wish to use your already developed code with its resources in android then you have to use it as a library.
But from the Building Android applications with Gradle tutorial I read something like...
Gradle supports a format called Android ARchive (AAR) . An AAR is similar to a JAR file, but it can contain resources as well as compiled bytecode. This allows that an AAR file is included similar to a JAR file**.
Does it means that we can use .aar file as an .jar file but with facility of using resources also?
Then I have tried to crate .aar file with the help of Android Studio, but .aar file doesn't contain layout XMLs or images -- it contains some layout and resources but it doesn't contain projects other resources file.
At last I am having the only same, annoying, stupid question: Can we use whole project with its resources with only one file like .jar or .aar or any other file format?

RajaReddy is quite mistaken. The JAR contains only code; you cannot access resources that way.
Google distributes their own "Google Play Services Library" as an Android library project, containing the binary code in a JAR file in the lib directory, the resources in the res directory, and an UnusedStub class in the src directory. If a better approach were viable yet I think they'd be using it.
UPDATE: While Android Studio is still in beta, it includes (buggy) support for AAR files. Seems this will eventually be the way to go.

Library projects bin folder contains jar file, copy that jar file in your main Application ( project ) libs folder we can get all the resource folders like this.
Follow these steps !
1) make your library project a normal project by deselecting IsLibrary flag.
2) Execute your project as Android Application. (It will not show any error)
3) you'll find a .jar file in bin folder..
4) Copy .jar in libs folder of your main application.
this will works fine with all the resources.

I was looking for the same thing for years. Combining byte code of java and resources (xml and other files) into one package. Currently I don't think its possible because even google has to include add resources separately in google play services lib available in the SDK .
What you can do best is generate a .aar or .jar file and add a folder of missing resource files.

How to build an Android project to jar that included other project

How can I build one Android project to jar that is can included in other android project? When I use eclipse export an Android project to jar and use the jar to other android project ,The "R" file and the resource files will be error。

Android resource files (which are represented in your R.java files) cannot be put into Jars. That is why libraries such as ActionBarSherlock require to be opened as library projects, instead of simple Jars.

You can build Android Library Project to jar, but within library project you should prevent using R class, Instead of R class you can use reflection to load resources.
For example if you need to load string from strings.xml file
int id = context.getResources().getIdentifier("string_name", "string", context.getPackageName());
String value = context.getString(id);
But this is what they mentioned about getIdentifier method:
Note: use of this function is discouraged. It is much more efficient to retrieve resources by identifier than by name.

You can build Android Project to jar file but don't use any Resource file.
B'coz when you will try to use that jar file in your application at run time Resource not Found exception will come.
So while creating jar file please unchecked res,gen,Manifest, etc.
You can Define your Base Activity class, Base Interface, Database Manager, GPS Manager
in your library project and use it in your our application it will surely work.
So see the below screen shots.
Thanks

Android how to export jar with resources?

I create an Android project for build my custom widget, and I want to export it as a jar for other project so that reuse them conveniently, but now a problem is, I can't use resources which is included in my custom widget jar, for example a png picture, it gets a null from the resource Id of class R! How can I sovle it?
Update question:
How can I parse LayerDrawable xml from assets folder in code?

You cannot export self-contained Android Library jar at this time and announced will be available in the future SDK release.
https://developer.android.com/guide/developing/projects/index.html#LibraryProjects

You cannot export the Android Project to Jar with Resources. What you can do is Make First Project as Library and then Add that to another project.
See Documentation Here shows how to Setup a Project as Library and use in another Project

In order to get the app working with my exported library .jar file, I had to copy everything in the resources directory "res" from the library project to the application project. Also had to merge file string.xml as well as merge the ApplicationManfiest.xml files as well. To add the project as a library through eclipse is much simpler.

Referencing .so files from an Android library

I've built OpenSSL into an Android Library that I would like to reference from another Android project.
Unfortunately,
Yes, I do need OpenSSL, as I need to change the behaviour of dependant Android classes not in the public API. (not enough space here)
My experience with native code is non-existant.
The project is selected as a library in Preferences > Android
This library is referenced from a second Android project
My Questions are these
How can I reference the .so files in my Android library from Android.mk in my second project so that I can build dependant files there? I'd prefer not to put the .so files directly in my second project - but if that is the only solution I would accept reasons and directions as an answer.
How should I include/reference the .so file in files I am building in the second project?
Surely, it is something simple.
Thanks in advance.

once you generate (.so) library file, then make a folder in your applitcation's project folder named "libs/armeabi/" put (.so) file in this folder
and in your application write
System.loadLibrary("library_name");
