I’m trying to load libspotify in my android app using NDK.
I’m using the library libspotify++ and jlibspotify. everything seems to be loaded but it crashes when libspotify is trying to load the library “libspotify.so.12”

I cannot use symbolic links in android.

Code:

public class Session {
    static {
        System.loadLibrary("spotify");
        System.loadLibrary("jlibspotify");
    }

}

This is what i get from objdump:

$arm-linux-androideabi-objdump -p libs/armeabi/libjlibspotify.so  | grep NEEDED
  NEEDED               libspotify.so.12
  NEEDED               libstdc++.so
  NEEDED               libm.so
  NEEDED               libc.so
  NEEDED               libdl.so
$arm-linux-androideabi-objdump -p libs/armeabi/libspotify.so  | grep NEEDED
  NEEDED               libm.so
  NEEDED               libc.so
  NEEDED               libdl.so

    The answer from Mārtiņš is correct, it should be build with Android’s NDK build system.
    When don’t having controle over the library there is a workaround:

    Instead of loading the library with System.loadLibrary( “JLibSpotify” );
    i manualy copied /data/data/se.warting.spotify/lib/libspotify.so to /data/data/se.warting.spotify/libspotify.so.12
    And then loaded the library with:

    System.load("/data/data/se.warting.spotify/libspotify.so.12");

    After that i could load jlibspotify as normal:

    System.loadLibrary("jlibspotify");
