}
private void installerBBM() {
Uri uri = Uri.fromFile(new File("/data/app/BBM.apk"));
Intent intent2 = new Intent(Intent.ACTION_INSTALL_PACKAGE);
intent2.setData(uri);
intent2.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
intent2.putExtra(Intent.EXTRA_RETURN_RESULT, true);
intent2.putExtra(Intent.EXTRA_ALLOW_REPLACE, true);
