To make it a bit more generic you should use something like the following:
PackageManager pm = context.getPackageManager();
Intent mainAppIntent = pm.getLaunchIntentForPackage( context.getPackageName() );
mainAppIntent.addFlags( Intent.FLAG_ACTIVITY_REORDER_TO_FRONT );
context.startActivity( mainAppIntent );
This way it pulls the package from the context, which should be the application that the ANE is packaged in. So that it will launch the application that the ANE was packaged in rather than the hardcoded application.
