how to resolve this error.....i am trying to implement custom firebase notification application
<p>Error:(29, 44) error: cannot access AbstractSafeParcelable
class file for com.google.android.gms.common.internal.safeparcel.AbstractSafeParcelable not found </p>

<pre><code> public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
  private static final String TAG = MyFirebaseInstanceIDService.class.getSimpleName();

@Override
public void onTokenRefresh() {
    super.onTokenRefresh();
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();

    // Saving reg id to shared preferences
    storeRegIdInPref(refreshedToken);

    // sending reg id to your server
    sendRegistrationToServer(refreshedToken);

    // Notify UI that registration has completed, so the progress indicator can be hidden.
    Intent registrationComplete = new Intent(Config.REGISTRATION_COMPLETE);
    registrationComplete.putExtra("token", refreshedToken);
    LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete);
}

private void sendRegistrationToServer(final String token) {
    // sending gcm token to server
    Log.e(TAG, "sendRegistrationToServer: " + token);
}

private void storeRegIdInPref(String token) {
    SharedPreferences pref = getApplicationContext().getSharedPreferences(Config.SHARED_PREF, 0);
    SharedPreferences.Editor editor = pref.edit();
    editor.putString("regId", token);
    editor.commit();
}
