我有一项服务，可以通过聊天发送通知。现在，该服务仅在日志中显示消息。但是它并没有在logcat上写任何东西...就像服务没有执行一样。我在服务中放置了一个断点，调试模式从未在该断点处停止。
我在这里找到了发送通知的示例： https://blog.usejournal.com/send-device-to-device-push-notifications-without-server-side-code-238611c143 这个例子很完美。
这是我的服务代码：
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private final String ADMIN_CHANNEL_ID ="admin_channel";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.i("******", remoteMessage.getData().get("title") );
}
}
这是您在聊天中发送消息的代码：
private void mandarNotificacion(String message) {
TOPIC = "/topics/userABC"; //topic must match with what the receiver subscribed to
String NOTIFICATION_TITLE = "Nuevo Mensaje";
String NOTIFICATION_MESSAGE = message;
JSONObject notification = new JSONObject();
JSONObject notifcationBody = new JSONObject();
try {
notifcationBody.put("title", NOTIFICATION_TITLE);
notifcationBody.put("message", NOTIFICATION_MESSAGE);
//notifcationBody.put("token",uReceiber.getToken());
notification.put("to", TOPIC);
notification.put("data", notifcationBody);
} catch (JSONException e) {
Log.e(TAG, "onCreate: " + e.getMessage() );
}
sendNotification(notification);
}
private void sendNotification(JSONObject notification) {
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(FCM_API, notification,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.i(TAG, "onResponse: " + response.toString());
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MessageActivity.this, "Request error", Toast.LENGTH_LONG).show();
Log.i(TAG, "onErrorResponse: Didn't work");
Log.i("******", error.toString());
}
}){
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("Authorization", serverKey);
params.put("Content-Type", contentType);
return params;
}
};
MySingleton.getInstance(getApplicationContext()).addToRequestQueue(jsonObjectRequest);
}
一些初始变量：
final private String FCM_API = "https://fcm.googleapis.com/fcm/send";
final private String serverKey = "key=" + "key";
final private String contentType = "application/json";
final String TAG = "NOTIFICATION TAG";
还有Manifiedt：
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>º
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"

android:roundIcon="@mipmap/ic_launcher_round"

android:theme="@style/AppTheme">

</activity>
<service
android:name=".Notificaciones.MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
<service
android:name="com.gpp.messenger.Notificaciones.MyFirebaseMessagingService"
android:enabled="true"
android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</service>
</application>
想到的任何想法都能派上用场，我不知道还能尝试什么。
感谢您的帮助
