Question

我使用此代码在屏幕顶部显示通知（例如WhatsApp），但不会付出任何代价，它只显示通知栏上的图标。

TThread.CreateAnonymousThread(
    procedure
    begin
       TThread.Synchronize(TThread.CurrentThread,procedure()
       var
       pru:integer;
        begin
        pru := 2;
if NotifAudio then begin
MediaPlayer1.FileName := (TPath.GetDocumentsPath + PathDelim + 'iclassy.mp3');
MediaPlayer1.Play;
end;
  BIIntent:= TAndroidHelper.Context.getPackageManager().getLaunchIntentForPackage(TAndroidHelper.Context.getPackageName());
  BresultPendingIntent:=  TJPendingIntent.JavaClass.getActivity(TAndroidHelper.Context, 0, BIIntent, TJPendingIntent.JavaClass.FLAG_UPDATE_CURRENT);
  BntfBuilder:= TJNotificationCompat_Builder.JavaClass.init(TAndroidHelper.Context);
  BntfBuilder.setSmallIcon(TAndroidHelper.Context.getResources.getIdentifier(StringToJString('ic_bad_area'), StringToJString('drawable'), TAndroidHelper.Context.getPackageName));
  BntfBuilder.setContentTitle(StrToJCharSequence('Title'));
  BntfBuilder.setContentText(StrToJCharSequence('Subtext'));
  BntfBuilder.setPriority(pru);
  BntfBuilder.setContentIntent(BresultPendingIntent);
  BntfBuilder.setAutoCancel(False);
  if FixNotif2 = True then BntfBuilder.setOngoing(True);
  BntfBuilder.setPriority(pru); // priority is set to MAX (2)
  BNtf:= BntfBuilder.build;
  BadArea_Bool := True;
  ntfManager:= TJNotificationManager.Wrap((TAndroidHelper.Context.getSystemService(TJContext.JavaClass.NOTIFICATION_SERVICE) as ILocalObject).GetObjectID);
  ntfManager.cancel(1);
  ntfManager.notify(2, BNtf);
end);
end).Start();

然而，WhatsApp通知在顶部显示正常，我也尝试了不同的手机，但没有，通知没有在屏幕顶部显示圆角矩形，只需在通知栏上添加小图标。我错过了什么吗？

解决包括振动：

BntfBuilder.setDefaults(pru); // pru = 2

Android通知最高优先级无效
