Firebase推送通知无效

标签: android firebase firebase-notifications

我开发了一个android应用程序。我使用firebase进行通知。我阅读了firebase文档然后分别制作了它们。我可以使用InstanceID令牌向一台设备发送推送通知。但我无法向所有设备发送推送通知。请帮帮我。

MyFirebaseMessagingService.java

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());
    }
    // [END receive_message]

    /**
     * Create and show a simple notification containing the received FCM message.
     *
     * @param messageBody FCM message body received.
     */
    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 /* Request code */, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_stat_ic_notification)
                .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());
    }
}

MyFirebaseInstanceIDService.java

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.
    }
}

MainActivity.java

public class MainActivity extends AppCompatActivity {

    private static final String TAG = "MainActivity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if (getIntent().getExtras() != null) {
            for (String key : getIntent().getExtras().keySet()) {
                String value = getIntent().getExtras().getString(key);
                Log.d(TAG, "Key: " + key + " Value: " + value);
            }
        }

        Button subscribeButton = (Button) findViewById(R.id.subscribeButton);
        subscribeButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // [START subscribe_topics]
                FirebaseMessaging.getInstance().subscribeToTopic("news");
                Log.d(TAG, "Subscribed to news topic");
                // [END subscribe_topics]
            }
        });

        Button logTokenButton = (Button) findViewById(R.id.logTokenButton);
        logTokenButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d(TAG, "InstanceID token: " + FirebaseInstanceId.getInstance().getToken());
            }
        });
    }

}

您应该在清单上包含预先许可:

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE"/> 

<uses-permission android:name="android.permission.WAKE_LOCK" />

<强>更新

不再需要预先准备,因为“FCM所需的所有权限现在都由库自动添加”

而不是&#34;立即发送&#34;在firebase web控制台通知gui尝试&#34;稍后发送&#34;将来很快就会有一段时间。发送即时可能有一个错误,它将过去的日期稍微发送,因此它永远不会被发送。

我已尝试过此处和其他帖子中发布的所有解决方案,但它们并不适用于我。我通过在我的设备上手动卸载并重新安装应用程序解决了问题。希望这有帮助。

转到https://console.firebase.google.com/转到菜单通知。在这里,您可以直接向任何特定设备或所有设备发送消息,也可以根据客户订阅的主题发送消息。

不要忘记, 我遇到了同样的问题,通过在我的服务中定义启用,导出为true,尝试像我这样做来解决..

  <service android:name=".MyFirebaseMessagingService"
            android:enabled="true"
            android:exported="true">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT"/>
            </intent-filter>
        </service>
</application>
