我實現了gcm使用this和消息顯示成功，但我沒有得到任何推送通知在我的設備。我不確定確切的問題在哪裏，爲什麼我沒有得到任何通知。下面是我在我的項目中實現的代碼，請讓我知道我要解決這個問題。 這是我的清單。Android的GCM推送通知沒有收到

這裏是我的活動。
public class MainActivity extends Activity {
private static final int PLAY_SERVICES_RESOLUTION_REQUEST = 9000;
private static final String TAG = "MainActivity";
private BroadcastReceiver mRegistrationBroadcastReceiver;
private ProgressBar mRegistrationProgressBar;
private TextView mInformationTextView;
private boolean isReceiverRegistered;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mRegistrationProgressBar = (ProgressBar) findViewById(R.id.registrationProgressBar);
mRegistrationBroadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Log.e("On Received ","?????? ");
mRegistrationProgressBar.setVisibility(ProgressBar.GONE);
SharedPreferences sharedPreferences =PreferenceManager.getDefaultSharedPreferences(context);
boolean sentToken = sharedPreferences.getBoolean(QuickstartPreferences.SENT_TOKEN_TO_SERVER, false);
if (sentToken) {
mInformationTextView.setText(getString(R.string.gcm_send_message));
}
else {
mInformationTextView.setText(getString(R.string.token_error_message));
}
}
};
mInformationTextView = (TextView) findViewById(R.id.informationTextView);
// Registering BroadcastReceiver
registerReceiver();
if (checkPlayServices()) {
Intent intent = new Intent(this, RegistrationIntentService.class);
startService(intent);
}
}
@Override
protected void onResume() {
super.onResume();
registerReceiver();
}
@Override
protected void onPause() {
LocalBroadcastManager.getInstance(this).unregisterReceiver(mRegistrationBroadcastReceiver);
isReceiverRegistered = false;
super.onPause();
}
private void registerReceiver() {
if (!isReceiverRegistered) {
LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter(QuickstartPreferences.REGISTRATION_COMPLETE));
isReceiverRegistered = true;
}
}
private boolean checkPlayServices() {
GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance();
int resultCode = apiAvailability.isGooglePlayServicesAvailable(this);
if (resultCode != ConnectionResult.SUCCESS) {
if (apiAvailability.isUserResolvableError(resultCode)) {
apiAvailability.getErrorDialog(this, resultCode, PLAY_SERVICES_RESOLUTION_REQUEST).show();
}
else {
Log.i(" ", "This device is not supported.");
finish();
}
return false;
}
return true;
}
}
，這裏是MyGcmListenerService
public class MyGcmListenerService extends GcmListenerService {
private static final String TAG = "MyGcmListenerService";
@Override
public void onMessageReceived(String from, Bundle data) {
Log.e("onMessageReceived ","@@@@@@@@@@@@");
String message = data.getString("message");
Log.d(TAG, "From: " + from);
Log.d(TAG, "message: " + message);
if (from.startsWith("/topics/")) {
// message received from some topic.
} else {
// normal downstream message.
}
sendNotification(message);
}
private void sendNotification(String message) {
Intent intent = new Intent(MyGcmListenerService.this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("GCM Message")
.setContentText(message)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}
可能沒有被註冊在GCM您的設備，所以調試並檢查您的設備ID。否則檢查一些不同的設備。 –
可能重複的[無法接收gcm消息]（http://stackoverflow.com/questions/33890426/can-not-receive-gcm-message） –
