Firebase Cloud Messagingの通知がデバイスで受信されない

Question

プロジェクトでFirebase Auth stuffを使用しています。今日私はFCMを自分のプロジェクトに組み込むことに決めました。しかし、Firebaseコンソールからの通知はありませんでした。私も再.jsonファイルをダウンロードしようとしましたが、うまくいきませんでした。あなたは私の問題についてどんな考えがありますか？

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()); 
} 

FirebaseIDService.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) 
{ 
} 
    } 

私の問題はMainActiviy.javaまでではないと思いますが、私はあなたのためにそれを示しています。

MainActivity.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; 

} 
}

あなたは正しくFirebaseを使用するようにアプリケーションを設定しているかどうかを確認することをお勧めします。プロジェクトのアプリディレクトリにあるbuild.gradleファイルにgoogle-servicesプラグインを追加します。

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

詳細については、tutorialを参照してください。

さらに、add FCM dependency。 app/build.gradleファイルにこの依存関係があるかどうか確認してください。

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