我的设备未收到Firebase云消息传递通知

Question

我在项目中使用了Firebase身份验证材料。今天我决定将FCM整合到我的项目中。但我无法从我的Firebase控制台收到任何通知。我也尝试重新下载.json文件，但没有成功。你们对我的问题有什么想法吗？

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()); 
} 

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) 
{ 
} 
    } 

我认为这个问题不是由我的MainActiviy.java决定的，但我会向你展示以防万一。

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; 

} 
}

您可能要检查是否已正确地配置您的应用程序中使用火力地堡。在项目的应用程序目录中的build.gradle文件中添加google-services插件。

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

查看此tutorial了解更多信息。

除此之外，add FCM dependency。确认您的app/build.gradle文件中是否存在此依赖关系。

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