我的设备未收到 Firebase 云消息通知

Question

我在项目中使用 Firebase Auth 的东西。今天，我决定将FCM整合到我的项目中。但是我无法从我的Firebase控制台发出任何通知。我也尝试重新下载.json文件，但没有成功。你们对我的问题有任何想法吗？

FirebaseMessageService.java

public void onMessageReceived(RemoteMessage remoteMessage){
    sendNotification(remoteMessage.getNotification().getBody());
}
private void sendNotification(String messageBody){
    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.mipmap.oto_takip)
            .setContentText(messageBody)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);
    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0, notificationBuilder.build());
}

FirebaseID服务.java

 public class FirebaseIDService extends FirebaseInstanceIdService
 {
private static final String TAG ="FirebaseIDService";
@Override
public void onTokenRefresh() {
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Token: " + refreshedToken);
    // If you want to send messages to this application instance or
    // manage this apps subscriptions on the server side, send the
    // Instance ID token to your app server.
    sendRegistrationToServer(refreshedToken);
}
private void sendRegistrationToServer(String refreshedToken)
{
}
   }

我认为问题不在于我的MainActiviy.java但为了以防万一，我将向您展示它。

主活动.java

 public class MainActivity extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener{
private Fragment fragment;
private FragmentManager fragmentManager;
public TextView tarih;
final String PREFS_NAME = "MyPrefsFile";
final String SHAREDPREF_DATE = "SharedPrefDate";
private FirebaseAuth firebaseAuth;
private TextView textViewUserEmail;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    firebaseAuth = FirebaseAuth.getInstance();
    if(firebaseAuth.getCurrentUser()==null)
    {
        startActivity(new Intent(this,Giris.class));
        finish();
    }
    setContentView(R.layout.activity_main);
@SuppressWarnings("StatementWithEmptyBody")
@Override
public boolean onNavigationItemSelected(MenuItem item) {
    // Navigation itemlerinin click olaylarını burada yapıyoruz.
    int id = item.getItemId();
    if (id == R.id.nav_kullanici)
    {
        startActivity(new Intent(MainActivity.this,Hesabim.class));
    }
    else if (id == R.id.nav_hatirlatma)
    {
        startActivity(new Intent(MainActivity.this,AyarlarActivity.class));
    }
    else if (id == R.id.nav_ipucu)
    {
        startActivity(new Intent(MainActivity.this,IpuclariSayfasi.class));
    }

    else if (id == R.id.nav_oyla)
    {

    }
    else if (id == R.id.nav_cikis)
    {
        firebaseAuth.signOut();
        finish();
        startActivity(new Intent(MainActivity.this, Giris.class));
        }
        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        drawer.closeDrawer(GravityCompat.START);
        return true;
}
}

您可能需要检查是否已正确配置应用以使用 Firebase。在项目应用目录的build.gradle文件中添加谷歌服务插件。

apply plugin: 'com.google.gms.google-services'

有关详细信息，请参阅本教程。

除此之外，还要添加 FCM 依赖项。确认您的app/build.gradle文件中是否有此依赖项。

compile 'com.google.firebase:firebase-messaging:10.2.0'

这篇SO帖子中建议的解决方案也可能有所帮助。
