Bug? ListenerService internal method cancelNotification error

[Alain75]

Hi,

I am developing an application which keeps a log of targeted notifications. The app lets the user choose from which packages the notifications are kept. I use of course the "NotificationListener" from @Erel which allows me to do the job.

Moreover, I am able to list all the fields of the notifications kept and to display them. It's nice, including the famous "key" which should allow my app to cancel the current notification without using its SBN, SBN I cannot serialize.

To cancel the notification (if it is still present), I use the internal method "cancelNotification" of the wrapper :

public int onStartCommand(Intent intent, int flags, int startId) {
      super.onStartCommand(intent, flags, startId);
      if (intent.hasExtra("b4a_cancel_all")) {
         this.cancelAllNotifications();
      } else if (intent.hasExtra("b4a_cancel")) {
         StatusBarNotification sbn = getSbnFromIntent(intent);
         if (VERSION.SDK_INT >= 21) {
            try {
               String key = (String)sbn.getClass().getMethod("getKey").invoke(sbn);
               this.getClass().getMethod("cancelNotification", String.class).invoke(this, key);
            } catch (Exception var11) {
               throw new RuntimeException(var11);
            }
         } else {
            this.cancelNotification(sbn.getPackageName(), sbn.getTag(), sbn.getId());
         }
      } else if (intent.hasExtra("b4a_getactive")) {
         StatusBarNotification[] all = this.getActiveNotifications();
         if (all != null) {
            StatusBarNotification[] var8 = all;
            int var7 = all.length;

            for(int var6 = 0; var6 < var7; ++var6) {
               StatusBarNotification sbn = var8[var6];

               try {
                  this.startService(this.createIntent("posted", sbn));
               } catch (ClassNotFoundException var10) {
                  throw new RuntimeException(var10);
               }
            }
         }
      }

I call it with inline Java :

Sub DismissNotification(key As String)
    Dim jo As JavaObject = Me
    Try
        Log("Dismiss "&key)
        jo.RunMethodJO("cancelKey",Array(key))
    Catch
        Log(LastException)
    End Try
End Sub
#If JAVA
public void cancelKey(String key) {
    try {
        this.getClass().getMethod("cancelNotification", String.class).invoke(this, key);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}
#End If

Unfortunately, I encountered the same error as @wes58 mentioned in his post, that is :

Dismiss 0|b4a.test1|233|null|10376
(IllegalArgumentException) java.lang.IllegalArgumentException: Expected receiver of type b4a.journal.notificationservice, but got java.lang.Class<b4a.journal.notificationservice>

@wes58 mentionned a fix for the listener but I didn't find it in the forum. Am I mistaken ?

It doesn't sound like a bug if you are making a call to an internal method. Better to start a new thread in the questions forum and explain what you are trying to do.

@Erel , what can I add to the beginning of my post which explains the purpose of the app : keep a log of some notifications of packages ? I can add screenshots and the entire NotificationService if you want.

Moreover, I said that the "cancelNotification" is internal in the listener but it is in fact a public method in android developer : https://developer.android.com/refer...rService#cancelNotification(java.lang.String)
and seems to be unreachable through the wrapper.
