LAMW how to request special overlay permission [SOLVED]

[Segator]

Hi people, i try the AppWindowManagerDemo1 before and work fine but with my new phono and android 10 no work fine, a make some search and this required an overlay permission but i change it on the manifest adding this:

Code: Pascal  [Select][+][-]

1. <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

and in the source code:

Code: Pascal  [Select][+][-]

1. if IsRuntimePermissionsNeed() then
2. begin
3.   SetLength(manifestpermissions,1);
4.   manifestPermission:='android.permission.SYSTEM_ALERT_WINDOW';
5.   self.RequestRuntimePermission(manifestPermissions, 2001);
6.   SetLength(manifestpermissions,0);
7. end;
8.  
9.  

not permission is requested and if i add the permission manually and try to do:

Code: Pascal  [Select][+][-]

1. jwindowManager1.addview(jpanel1.view);
2. jwindowmanager1.SetViewRoudCorner();
3. self.minimize();

the app crach

I fix the manifest xml file, now the project work in Andorid 7.0 (emultator) but still having 2 problems:

1: AppWindowManagerDemo1 not run in Android 10 (Samsung A10s)
2: I have to set the overlay permision manually.

I have to set the overlay permision manually.

How?

in the phone general settings permision, because this

Code: Pascal  [Select][+][-]

1. if IsRuntimePermissionsNeed() then
2. begin
3.   SetLength(manifestpermissions,1);
4.   manifestPermission:='android.permission.SYSTEM_ALERT_WINDOW';
5.   self.RequestRuntimePermission(manifestPermissions, 2001);
6.   SetLength(manifestpermissions,0);

I found this

Code: Pascal  [Select][+][-]

1. @RequiresApi(api = Build.VERSION_CODES.M)
2.   public void checkDrawOverlayPermission() {
3.    Log.v("App", "Package Name: " + getApplicationContext().getPackageName());
4.  
5.    // check if we already  have permission to draw over other apps
6.    if (!Settings.canDrawOverlays(context)) {
7.     Log.v("App", "Requesting Permission" + Settings.canDrawOverlays(context));
8.     // if not construct intent to request permission
9.     Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
10.      Uri.parse("package:" + getApplicationContext().getPackageName()));
11.     / request permission via start activity for result
12.     startActivityForResult(intent, REQUEST_CODE);
13.    } else {
14.     Log.v("App", "We already have permission for it.");
15.     disablePullNotificationTouch();
16.    }
17.   }

and i try to do this:

Code: Pascal  [Select][+][-]

1.     jIntentManager1.SetAction('Settings.ACTION_MANAGE_OVERLAY_PERMISSION');
2.     jIntentManager1.SetDataUriAsString('package: '+gapp.PackageName);
3.     jIntentManager1.StartActivityForResult(1001);

but nothing is happend.

i found this https://blog.floatingapps.net/2019/11/cant-grant-permissions-to-fa-because-of-draw-over-other-apps/ basically in android 10 you can't request other permission after the overlay permission grant, you must request this permission before others, about the always focused window i try to make a wrapper to the SetViewFocusable procedure in jWindowManager.java and if a call this the application crach

Finally i solved this particular request permission, i send a pull request to github, when this change you can do something like this:

Code: Pascal  [Select][+][-]

1. jIntentManager1.SetAction(iaManageOverlayPermission);
2. jIntentManager1.SetDataUriAsString('package:'+gapp.PackageName);
3. jIntentManager1.StartActivityForResult(1006);
4.  

but for now i can't know if the permission is granted or not.

You can try handle event  the "OnActivityResult"   from jForm...

i try it but the variable resultCode only manage RESULT_CANCELED and RESULT_OK with no change effect in action manage overlay permission window, even with the overlay button active is not a result_ok.

this not work:

Code: Pascal  [Select][+][-]

1. if resultCode = RESULT_OK then
2. ShowMessage('done');
