[英]FCM push notification not working on some devices
我們使用FCM創建了一個帶有通知的聊天應用程序,我的代碼也是正確的,我的設備也正在獲取推送通知數據,但是除非中國添加了應用程序,否則某些中國制造的設備(如vivo,oppo,一加,小米)不允許顯示通知。各個制造商的受保護應用列表。 是他們對此的任何解決方案。

private NotificationManagerCompat notificationManager;
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Log.d("test","call");
notificationManager = NotificationManagerCompat.from(this);
sendNotification(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());
}
private void sendNotification(String title, String msg) {
Intent resultIntent = new Intent(this, ActivitySplashScreen.class);
String channelId = getString(R.string.chc);
String channelName = "Message Notification";
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addNextIntentWithParentStack(resultIntent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(99, PendingIntent.FLAG_UPDATE_CURRENT);
Notification notification = new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.mipmap.ic_launcher_round)
.setContentTitle(title)
.setContentText(msg)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
.setContentIntent(pendingIntent)
.build();
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
NotificationManager manager = getSystemService(NotificationManager.class);
NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_HIGH);
manager.createNotificationChannel(channel);
}
notificationManager.notify(10, notification);
}
我認為這沒有通用的解決方案,因為您的應用基於google-FCM,這意味着android設備會定期與google-internet-services通信。
據我所知,google-FCM在中國已被阻止(=無法訪問)
我可以確認此實施方式在One Plus和Xiaomi設備上運行良好(我們有大量用戶在該設備上使用我們的應用,並且從中未發現有關FCM通知的崩潰或問題)。
無法確認Vivo或Oppo的任何內容(到目前為止,我們確實知道我們沒有用戶使用這種設備)。
最重要的是,如果有關應用程序是在前台還是在后台,通知功能都將得到很好的實現。 如果有人想對此事進行放大,那么本文將以一種簡單的方式對其進行解釋。
現在,我用於Android中FCM實現的代碼:
// MyMessagingService
public class MyFirebaseMessagingService extends FirebaseMessagingService {
public static final String TAG = "Firebase Msg";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Map<String, String> data = remoteMessage.getData();
final LocalNotification localNotification = new LocalNotification();
//data --> entityId - entityType - pushNotificationType
// Check if message contains a data payload.
if (data.size() > 0) {
localNotification.setEntityId(data.get("entityId"));
localNotification.setEntityType(data.get("entityType"));
localNotification.setPushNotificationType(data.get("pushNotificationType"));
localNotification.setTitle(data.get("title"));
localNotification.setBody(data.get("body"));
localNotification.setIcon(data.get("icon"));
localNotification.setDate(new Date().getTime());
localNotification.setRead(false);
}
if (localNotification.getEntityId() != null) {
LocalNotification notificationRetrieved = FirebaseNotificationsHelper.insertLocalNotification(localNotification);
FirebaseNotificationsHelper.createNotificationInStatus(notificationRetrieved);
}
}
}
//創建通知狀態
static void createNotificationInStatus(LocalNotification localNotification) {
String notificationChannelId = App.getContext().getString(R.string.default_notification_channel_id);
String notificationChannelName = App.getContext().getString(R.string.default_notification_channel_name);
String notificationChannelDescription = App.getContext().getString(R.string.default_notification_channel_description);
NotificationCompat.Builder notificationBuilder;
NotificationCompat.Builder notificationBuilderPublicVersion;
notificationBuilder = new NotificationCompat.Builder(App.getContext(), notificationChannelId);
notificationBuilderPublicVersion = new NotificationCompat.Builder(App.getContext(), notificationChannelId);
notificationBuilder.setDefaults(NotificationCompat.DEFAULT_VIBRATE | NotificationCompat.DEFAULT_LIGHTS | NotificationCompat.DEFAULT_SOUND)
.setWhen(System.currentTimeMillis())
.setSmallIcon(R.drawable.ic_stat_push_notif)
.setTicker(localNotification.getTitle())
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
.setContentTitle(localNotification.getTitle())
.setContentText(localNotification.getBody())
.setStyle(new NotificationCompat.BigTextStyle().bigText(localNotification.getBody()))
.setPublicVersion(notificationBuilderPublicVersion.setSmallIcon(R.drawable.ic_stat_push_notif).setContentTitle(localNotification.getTitle()).
setWhen(System.currentTimeMillis()).setContentText(localNotification.getBody()).build())
.setGroup(NOTIFICATION_GROUP)
.setVibrate(new long[]{1000, 1000, 1000, 1000, 1000})
.setAutoCancel(true);
int notificationId = SharedPreferencesUtils.getInstance(App.getContext()).getIntValue(PREF_KEY_NOTIFICATION_ID, 0);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationManager notificationManager = (NotificationManager) App.getContext().getSystemService(Context.NOTIFICATION_SERVICE);
NotificationChannel notificationChannel = new NotificationChannel(notificationChannelId, notificationChannelName, NotificationManager.IMPORTANCE_HIGH);
// Configure the notification channel.
notificationChannel.setDescription(notificationChannelDescription);
notificationChannel.enableLights(true);
notificationChannel.setLightColor(Color.RED);
notificationChannel.setVibrationPattern(new long[]{0, 1000, 500, 1000});
notificationChannel.enableVibration(true);
notificationChannel.setLockscreenVisibility(NotificationCompat.VISIBILITY_PUBLIC);
notificationChannel.setImportance(NotificationManager.IMPORTANCE_HIGH);
notificationManager.createNotificationChannel(notificationChannel);
notificationManager.notify(notificationId, notificationBuilder.build());
} else {
/* Kitkat and previous versions don't show notifications using NotificationManagerCompat */
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {
NotificationManager notificationManager = (NotificationManager) App.getContext().getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(notificationId, notificationBuilder.build());
} else {
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(App.getContext());
notificationManager.notify(notificationId, notificationBuilder.build());
}
}
notificationId++;
SharedPreferencesUtils.getInstance(App.getContext()).setValue(PREF_KEY_NOTIFICATION_ID, notificationId);
}
