How do you add an existing .so library to an Android Studio project?

Question

There are several sources out there that say you should create a directory in src/main/ called jniLibs/armeabi and add your compiled .so file to this location. Then load your library using System.loadLibrary("nameOflib").

My issue is that when I define my function

public native long create();

create() gives the error:

Cannot resolve corresponding JNI function Java_com_brendan_myApplication_MainActivity_create. Reports native method declarations in Java where no corresponding JNI function is found in the project.

Any ideas?

Answer 1

Turns out I can still call the jni methods even though there is an error saying "Cannot resolve corresponding JNI function".

Answer 2

to solve that problem, just follow this steps and visit a link below:

Adding .so Library in Android Studio 1.0.2

1. Create Folder "jniLibs" inside "src/main/"
2. Put all your .so libraries inside "src/main/jniLibs" folder
3. Folder structure looks like,
   |--app:
   |--|--src:
   |--|--|--main
   |--|--|--|--jniLibs
   |--|--|--|--|--armeabi
   |--|--|--|--|--|--.so Files
   
4. No extra code requires just sync your project and run your application.

EDIT: I suppose that might not be problem with configuration, but with how you declare native method signatures in Android NDK
