Prevent Android Studio from embedding library dependency into aar file

I have developed an Android library which also contains native code.
My native code dynamically links to another library. So I added this into my CMakeList.txt:
target_link_libraries(sysnative /path/to/libexample.so)
The problem is Android Studio will copy libexample.so into the .aar file.
I don't want this. I have other projects using libexample.so.
If each of my projects have libexample.so in the aar file, I will have it multiple times.

Android Library Project Export

I am developing first time Android Library Project that have external dependences of different libraries like retrofit and ormlite-android. The problem i am facing right now is when i use my Android Library Project .aar file inside other project the class not found exception occur when run the code. Please can any one guide me how to fix such issues. Do i have to add external libraries reference inside my dependent app ?

How to use an AAR file with Android Studio 1.2

EDIT:
When I use the response of How to manually include external aar package using new Gradle Android Build System I have an error.
BASE:
I never use AAR file, with the release of Android Studio we can use it.
But I don't find any explanation to use it.
Do you know how to use it?
It's necessary to make some things like ask for the permissions or create the dependencies?
Thanks

AAR format is a jar file containing a compiled Android Library project. Here's some info on what is inside an AAR file
What this means for app developers is that instead of (the old way):
Downloading the source code of a library project
Building it in eclipse
Setting your application project to depend on the local library project
You can instead add the dependency specification to your project/app/build.gradle's dependencies block: compile 'fr.baloomba:viewpagerindicator:2.4.2'
Then gradle (on the next build) searches for the aar file in a central binary repository, downloads the library and allows you to use it's functionality in your project. ( ex: http://search.maven.org/remotecontent?filepath=fr/baloomba/viewpagerindicator/2.4.2/viewpagerindicator-2.4.2.aar )
You can also search the central repository's web interface for libraries to depend on. Once you've clicked on a library to add to the project, click "Gradle/Grails" under "Dependency Information" to copy the line to add to build.gradle.
In my opinion this is a huge improvement.
You don't need to add any permissions to the app, either way, adding a Library project dependency is a compile time thing, not runtime or user-facing.

Adding library with and without resources in android

I'm new to android development. I wanted to implement Navigation Drawer feature in my application, which requires android.support.v4.jar file to be included in my project. I'm using Android Studio to develop my application so I included the compile "com.android.support:support-v4:18.0.+" in my build.gradle file as mentioned in https://developer.android.com/tools/support-library/setup.html. My project is working fine, I was able to successfully include my library. I did adding library without resources.
What I couldn't figure out is the difference between adding library without resources and adding library with resources. Does adding library with resources mean including some sample project?
Thanks

For Android Studio projects using Gradle (which is what your project is), there isn't an important distinction between libraries with resources and without resources. The Gradle build system's support for Android is more advanced than anything available to Eclipse and can support libraries with and without resources the same way (you just add the compile statement to your dependencies as you have; you can also do it more easily via the Project Structure dialog).
In Eclipse, if you want to include a library with resources, you have to add it as a project (similar to an Android Studio module) to ensure the resources get included directly; there you can't include resourceful libraries as simple jar files.

Jar mismatch scenario

I'm encountering a lot of jar mismatch errors lately and I'd like to avoid them in the future.
So, here's my question: suppose I have an app that uses 2 library projects, both of which use the v4 support library jar. In total, I have 3 jar files. What can I do to avoid the jar mismatch error?
All I've read so far is the case where you have a project and a single library project. In this case, I think your supposed to delete the jar file in the project and keep the one in the library project.

This is quite common if your project references several libraries, and each library references the same other library.
An example of this, your app is referencing the android support library v4, and you have 2 libraries which are also referencing the support library v4.
If you update your apps reference to the support library, but you don't update the support library v4 in your other libraries you will see this error.
The best thing is on each referenced library and your app, right click on the project > android tools > add support library. This will get the latest version and you should no longer see these errors.

If you're facing mismatch issue then simply copy one of them and paste in remaining libraries. E.g. as you've 3 v4 support library jars then copy one of them and paste at place of remaining two jars.

Try to understood by my example I used Map and Facebook in My project now Facebook,Map and my project have Android support jar so i removed Android Support jar from Facebook,My project but remain jar on Map,now i'm addded Android-Map-Extension as library project on Facebook And finally add Facebook library project on My project .....
