以下是MyFirebaseMessagingService.java文件的代码:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
/**
* Called when message is received.
*
* @param remoteMessage Object representing the message received from Firebase Cloud Messaging.
*/
// [START receive_message]
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// TODO(developer): Handle FCM messages here.
// If the application is in the foreground handle both data and notification messages here.
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.
Log.d(TAG, "From: " + remoteMessage.getFrom());
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
sendNotification(remoteMessage.getNotification().getBody());
}
// [END receive_message]
/**
* Create and show a simple notification containing the received FCM message.
*
* @param messageBody FCM message body received.
*/
public void sendNotification(String messageBody) {
Intent intent = new Intent(this, SettingsActivity.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("FCM Message")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}
问题是,当我试图在应用程序仍在屏幕上的情况下发送Firebase通知时,它会崩溃,多次出现此错误:java.lang.IllegalArgumentException:URI:content://com.android.contacts/phone_lookup/?encrypt=%20%3C%202,呼叫用户:com.android.mms:10015,呼叫包:com.android.mms
我真的不知道这里出了什么问题
请让我知道。尝试调试onMessageReceived(),您必须获得remoteMessage。getNotification()=null如果您在推送中未发送通知块:
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
// Check if remoteMessage.getNotification() == null ??
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
sendNotification(remoteMessage.getNotification().getBody());
}
还可以使用完整的错误日志更新您的问题。只需确保应用程序的build.gradle中的“apply plugin:'com.google.gms.google services'”一行位于build.gradle文件的最底部。否则,当收到消息时,应用程序可能会崩溃。能否添加整个堆栈跟踪?我想看看这是从哪里来的。
