ExceptionInInitializerError Physics World

Question

I searched in a number of forums and it seems to be a common question. However i couldnt find a solution. I didnt do anything crazy so it seems stange that this happens.

@Override
protected Scene onCreateScene() {
    Scene s = new Scene();
    PhysicsWorld mWorld=new PhysicsWorld(new Vector2(0, SensorManager.GRAVITY_EARTH),true);
    s.registerUpdateHandler(mWorld);
    final Sprite eliSprite = new Sprite(400, 240, james_walking[3], getVertexBufferObjectManager());
    eliSprite.setScale(0.5f);
    s.attachChild(eliSprite);
    s.setTouchAreaBindingOnActionDownEnabled(true);
    return s;
}

I dont have much more to say because i dont know much about Andengine so a dummies explanation would be apreciated. After adding what you said the error goes out, however the PhysicsWorld still doesnt work. THe logcat says

Probably native libraries (.so files from lib dir) is missing from your APK. Check your project settings / build configuration.

If you're using android studio, you have to modify the sourceSet of andEngine and andEnginePhysicsBox2DExtension in build.gradle.

You have a folder in that projects where there are so files, you need to include the native libraries from there.

Check my answer here: jniLibs are not extended in gradle

Update based on your comments:

Add this to andEngine, andEnginePhysicsBox2d and your game build.gradle:

sourceSets {
    main {
        jni.srcDirs = []
        jniLibs.srcDir 'libs'
    }
}

Also add this to the defaultConfig section, for andEngine:

ndk {
   moduleName "andEngine"
}

and for andEnginePhysicsBox2d:

ndk {
    moduleName "andEnginePhysicsBox2dExtension"
}

Sorry, but how do i check that? – qera hile Feb 26 '15 at 21:25
Do you build your project with eclipse or intellij/android studio? – Szörényi Ádám Feb 26 '15 at 21:27
I don't know the folders in your andEngine project because it can be using the eclipse hierarchy, which it's in the libs folder, and it can use the new hierarchy. Check for .so files in andEnginePhysicsBox2D. – Szörényi Ádám Feb 26 '15 at 21:56
ok, I have a libs/aremabi_v7a folder where there is one .so in the andEnginePhysicsBox2D module. what should i do with it? – qera hile Feb 26 '15 at 22:25
Well, the error is gone but the PhysicsWorld still doesnt work, – qera hile Feb 27 '15 at 15:13
My bad! forgot the physics connector – qera hile Feb 27 '15 at 20:25
Error:(5, 0) Could not find property 'jni' on source set 'main'. Open File – HendraWD Jun 23 '16 at 05:32
so to be specific, sourceSets should be inside android section, and i change jniLibs.srcDir 'libs' to jniLibs.srcDir 'src/main/jniLibs' – HendraWD Jun 23 '16 at 05:41
