在Android 13中,新的通知策略可能会导致一些通知没有及时显示。为了解决这个问题,可以通过以下方法:
代码示例:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { NotificationChannel channel = new NotificationChannel("channel_id", "channel_name", NotificationManager.IMPORTANCE_DEFAULT); NotificationManager manager = getSystemService(NotificationManager.class); manager.createNotificationChannel(channel); }
代码示例:
NotificationCompat.Builder builder = new NotificationCompat.Builder(context, CHANNEL_ID) .setSmallIcon(R.drawable.notification_icon) .setContentTitle("Notification title") .setContentText("Notification text") .setPriority(NotificationCompat.PRIORITY_HIGH);
代码示例:
NotificationManager manager = getSystemService(NotificationManager.class); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P && !manager.isNotificationPolicyAccessGranted()) { startActivity(new Intent(Settings.ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS)); }
通过上述方法,应该能够解决Android 13中通知不显示的问题。
