How to import multiple unity android modules in to an Single Android Application in Android Studio ?

Questions & Answers
1

In Android native app there are Two Buttons , On click on button 1 it should navigate to Unity_Module_1 and Click on button 2 it should navigate to Unity_module_2.

When i import One Unity module and click on button 1 it navigates properly and launched.

When two modules are imported ,
ERROR : More than one file was found with OS independent path 'lib/armeabi-v7a/libmain.so files

I fixed the issue by adding the below line of code in App build.gradle

packagingOptions {

   // exclude 'project.properties'
    exclude 'lib/armeabi-v7a/libmain.so'
    exclude 'lib/armeabi-v7a/libmono.so'
    exclude 'lib/armeabi-v7a/libunity.so'
}

Once after fixing the issue , after gradle sync , when i click
Button 1 it navigate to Unity 1 module ,
Button 2 it also navigating to Unity 1 module and sometimes its getting hanged or crashed.

Can someone help me with this integration , need to know weather it is possible .
