你好,我有一个android应用程序,我使用了Firebase通知,它的工作正常,现在我需要接收无提示的无声推送,或者,当应用程序在运行时,我尝试了一些想法,并且它在后台运行,或者在后台运行时终止了工作!如果有人有想法解决这个问题,请告诉我:)这是我的代码
public class MyFirebaseMessagingService extends FirebaseMessagingService {
Boolean isSilent;
String Silent = "";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
try {
Bundle bundle = new Bundle();
for (Map.Entry<String, String> entry : remoteMessage.getData().entrySet()) {
bundle.putString(entry.getKey(), entry.getValue());
Log.d(entry.getKey(), entry.getValue());
}
// remoteMessage.getData().get("screen_id")
if (remoteMessage.getData().size() > 0) {
sendNotificationData(bundle.getString("data_title"), bundle.getString("data_body"), bundle.getString("screen_id"));
} else if (remoteMessage.getNotification() != null) {
sendNotification(remoteMessage.getNotification(), bundle.getString("screen_id"));
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
private void sendNotification(RemoteMessage.Notification notificationR, String screenId) {
NotificationManager nManager = (NotificationManager) this.getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
Intent intentNotification = new Intent(this, MainActivity.class);
intentNotification.putExtra("screen_id", screenId);
Log.v("sendNotification ", " >>>>>####>>>>>>>> " + screenId);
// finish previous activity
if (!Silent.equals("yes")) {
intentNotification.addFlags(android.content.Intent.FLAG_ACTIVITY_CLEAR_TOP);
intentNotification.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 50, intentNotification, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this.getApplicationContext())
.setContentTitle(notificationR.getTitle())
.setContentText(notificationR.getBody())
.setSmallIcon(getNotificationIcon())
.setLargeIcon(icon(getApplicationContext()))
.setLights(Color.LTGRAY, 1000, 1000)
.setAutoCancel(true)
.setTicker(notificationR.getTitle())
.setContentIntent(pendingIntent)
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
Notification notification = notificationBuilder.build();
// '|' Binary OR Operator copies a bit if it exists in either operand. to ensure no conflict on the flags
notification.flags = notification.flags | Notification.FLAG_SHOW_LIGHTS;
nManager.notify((int) SystemClock.currentThreadTimeMillis(), notification);
}
}
private void sendNotificationData(String dataTitle, String dataBody, String screenId) {
NotificationManager nManager = (NotificationManager) this.getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
Intent intentNotification = new Intent(this, MainActivity.class);
intentNotification.putExtra("screen_id", screenId);
if (!Silent.equals("yes")) {
intentNotification.addFlags(android.content.Intent.FLAG_ACTIVITY_CLEAR_TOP);
intentNotification.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 50, intentNotification, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this.getApplicationContext())
.setContentTitle(dataTitle)
.setContentText(dataBody)
.setSmallIcon(getNotificationIcon())
.setLargeIcon(icon(getApplicationContext()))
.setLights(Color.LTGRAY, 1000, 1000)
.setAutoCancel(true)
.setTicker(dataTitle)
.setContentIntent(pendingIntent)
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
Notification notification = notificationBuilder.build();
// '|' Binary OR Operator copies a bit if it exists in either operand. to ensure no conflict on the flags
notification.flags = notification.flags | Notification.FLAG_SHOW_LIGHTS;
nManager.notify((int) SystemClock.currentThreadTimeMillis(), notification);
}
@Override
public boolean zzE(Intent intent) {
isSilent = intent.hasExtra("silent");
if (isSilent) {
Silent = "yes";
}
return super.zzE(intent);
}
当应用程序正在运行时,此代码正在运行,但在后台或终止时无法运行!
最佳答案
当您的应用程序处于后台时,在“系统任务栏”上收到firbase通知消息,这就是为什么不调用FirebaseMessagingService.onMessageReceived的原因。
当您的应用程序在后台运行时,Android会将通知消息定向到系统任务栏。默认情况下,用户点击通知会打开应用启动器。
尝试发送将调用onMessageReceived的数据有效负载。然后您的代码将
工作
对于数据消息...。
从FirebaseInstanceIdService获取firebase令牌,并将其发送到应用服务器。
Google有很好的文档发送给它Here
您也可以使用php发送。
然后在onMessageReceived
if (remoteMessage.getData().size() > 0) {
String title = remoteMessage.getData().get("title");
String body = remoteMessage.getData().get("body");
String screen = remoteMessage.getData().get("screen");
sendNotification(title, body, screen );}
对于服务器端php实现
<?php
$path_to_fcm = "https://fcm.googleapis.com/fcm/send";
$headers = array(
'Authorization:key='YOUR_SERVER_KEY,
'Content-Type:application/json'
);
$reg_id_array = array
(
'token1',
'token2'
)
$mesg = array
(
'title'=>$_POST['title'],
'body'=> $_POST['message'],
'url'=>$_POST['Screen'],
);
$fields = array("registration_ids"=>$reg_id_array, 'data'=>$mesg);
$payload = json_encode($fields);
$curl_session = curl_init();
curl_setopt($curl_session, CURLOPT_URL, $path_to_fcm);
curl_setopt($curl_session, CURLOPT_POST, true);
curl_setopt($curl_session, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl_session, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_session, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_session, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );
curl_setopt($curl_session, CURLOPT_POSTFIELDS, $payload);
$Qresult = curl_exec($curl_session);
$httpcode = curl_getinfo($curl_session , CURLINFO_HTTP_CODE);
curl_close($curl_session);
if ($httpcode==200) {
echo "Success";
}
?>
