我有兩個設備。一個是運行API 26,另一個是API 21.我正在使用Google的firebase進行通知。除非我先打開應用程序,否則API 26設備不會收到推送通知。然後它收到一切正常。我不必先打開應用程序以接收API 27設備上的推送通知。任何想法,即使不打開應用程序,如何始終接受推送?我希望只需打開手機即可通知用戶。在android中關閉應用程序時不會顯示推送通知
private void sendNotification(String title, String messageBody, String clickAction) {
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
String id = "";
if (Build.VERSION.SDK_INT >= 26) {
id = "my_channel_01";
// The user-visible name of the channel.
CharSequence name = "myChannel";
// The user-visible description of the channel.
String description = "";
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel mChannel = new NotificationChannel(id, name,importance);
// Configure the notification channel.
mChannel.setDescription(description);
mChannel.enableLights(true);
// Sets the notification light color for notifications posted to this
// channel, if the device supports this feature.
mChannel.setLightColor(Color.RED);
mChannel.enableVibration(true);
mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
notificationManager.createNotificationChannel(mChannel);
}
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);
String channelId = getString(R.string.default_notification_channel_id);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, id)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(title)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
notificationManager.notify(1 /* ID of notification */, notificationBuilder.build());
}
你是如何從firebase發送通知的?它來自控制檯還是API? – zihadrizkyef
