I've got a .so library, which I've extracted from an other APK.
I've copied it into /libs/armeabi location in my project.
In my class, I'm loading it with
static { System.loadLibrary("mylib"); }
The app crashes with
08-03 07:52:08.089: E/AndroidRuntime(932): FATAL EXCEPTION: main java.lang.ExceptionInInitializerError at java.lang.Class.newInstanceImpl(Native Method) at java.lang.Class.newInstance(Class.java:1319) at android.app.Instrumentation.newActivity(Instrumentation.java:1053) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1974) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2084) at android.app.ActivityThread.access$600(ActivityThread.java:130) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1195) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4745) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) at dalvik.system.NativeStart.main(Native Method) Caused by: java.lang.UnsatisfiedLinkError: Couldn't load mylib: findLibrary returned null at java.lang.Runtime.loadLibrary(Runtime.java:365) at java.lang.System.loadLibrary(System.java:535) at com.example.mytestandroidapp.MainActivity.<clinit>(MainActivity.java:11) 08-03 07:52:08.089: E/AndroidRuntime(932): ... 15 more
I'm doing this in eclipse.
Here's the screen of the layout of my project:
