I shifted my app from eclipse to android studio but the app is giving errors of "could not find class". I have included all required libraries, jars,etc. And unlike other questions on S.O , my errors are related to my own classes, not classes from other libraries. And its mainly crashing on Handler in the class. Here is the log cat:

And this is code on line 886:

private Handler changeaddtHandler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        chageAddresstoGeoThread.interrupt();
        if (msg.obj.toString().equalsIgnoreCase("change_success")) {
            if (changeGeopoint != null) {
                CameraPosition cameraPosition = new CameraPosition.Builder()
                        .target(changeGeopoint).zoom(16).build();
                mMap.animateCamera(CameraUpdateFactory
                        .newCameraPosition(cameraPosition));
            } else {
                Toast.makeText(context, "Sorry did't find your location.",
                        Toast.LENGTH_SHORT).show();
            }
        }
    }
};

And the code was working fine on eclipse without any issues. Any help would be appreciated. Thanks

  • seem your library files are not included properly. do check module setting of your app. Commented Jun 25, 2015 at 6:16
  • I have modified my build.gradle for libraries, but as I am new to android studio I dont have much experience. Should I include my gradle here ? Commented Jun 25, 2015 at 6:19
  • you need not to modify things manually. just right click on the app -> go to module setting -> dependencies -> check if your libs are included and if not add via + button. Commented Jun 25, 2015 at 6:22
  • I have added all the libraries which were added in eclipse.... Commented Jun 25, 2015 at 6:32
  • class which is not found seems your own class and not of the libs. right ? Commented Jun 25, 2015 at 6:35

Reset to default

I solved the problem by addinf MultiDex support to my application. I was incompletely implementing MultiDex support, so some of my classes weren't in the proper dex file. To fix it, you have to do more than just set multiDexEnabled = true in your defaultConfig block. You also have to:

  1. Include compile 'com.android.support:multidex:1.0.0' in your dependencies
  2. Have your Application class extend MultiDexApplication instead of just Application. Alternatively, you can call MultiDex.install() in attachBaseContext() of your application.

See https://developer.android.com/tools/building/multidex.html for more details.
