私のコードでこのfirebaseプッシュ通知を使用すると、通知メッセージが表示されますが、そのあとアプリケーションは残念ながら閉じられません。致命的なエラーjava.lang.NullPointerException RemoteMessage $ Notification。 getBody() 'をnullオブジェクト参照で使用します。どのようにこのエラーを克服するには?
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
//Displaying data in log
//It is optional
Log.d(TAG, "From: " + remoteMessage.getFrom());
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
sendNotification(remoteMessage.getNotification().getBody());
//Calling method to generate notification
/*if (remoteMessage.getNotification() != null) {
sendNotification(remoteMessage.getNotification().getBody());
}*/
if (remoteMessage.getFrom() != null) {
sendNotification(remoteMessage.getNotification().getBody());
} else {
String SMessage = "Hello this is used for the testing";
sendNotification(SMessage);
}
}
//This method is only generating push notification
//It is same as we did in earlier posts
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, SBTVerfyLogin.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.notify)
.setContentTitle("Firebase Push Notification")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}
PHPコードを投稿できますか?おそらく、ペイロードに通知本体の値を含めないことになります。 –
