我正在尝试向单个设备发送 Firebase 通知,为此我已使用以下代码检索了 FCM 注册 token
:
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
/**
* Called if InstanceID token is updated. This may occur if the security of
* the previous token had been compromised. Note that this is called when the InstanceID token
* is initially generated so this is where you would retrieve the token.
*/
// [START refresh_token]
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
// TODO: Implement this method to send any registration to your app's servers.
sendRegistrationToServer(refreshedToken);
}
// [END refresh_token]
/**
* Persist token to third-party servers.
*
* Modify this method to associate the user's FCM InstanceID token with any server-side account
* maintained by your application.
*
* @param token The new token.
*/
private void sendRegistrationToServer(String token) {
// Add custom implementation, as needed.
}
}
这是 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,当我尝试在应用仍在屏幕上时发送 Firebase 通知时,它会崩溃并多次出现此错误: java.lang.IllegalArgumentException: URI: content://com. android.contacts/phone_lookup/?encrypt=%20%3C%202,调用用户:com.android.mms:10015,调用包:com.android.mms
我真的不知道这里出了什么问题!
请告诉我。
最佳答案
尝试调试你的onMessageReceived(),如果你没有在推送中发送通知 block ,你必须得到remoteMessage.getNotification() = null:
@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());
}
同时使用完整的错误日志更新您的问题。
