hi.
I don’t understand why it doesn’t work for me
android.permission.READ_PHONE_STATE

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TfrmMain.frmMainJNIPrompt(Sender: TObject);var  manifestPermissions:
TDynArrayOfString;beginif IsRuntimePermissionNeed() then   // that is,
if target API >= 23   begin   
 ShowMessage('RequestRuntimePermission....');     ////https://develope
r.android.com/guide/topics/security/permissions#normal-dangerous   
 SetLength(manifestPermissions, 1);     manifestPermissions[1]:=
'android.permission.READ_PHONE_STATE';      //from
AndroodManifest.xml   
 Self.RequestRuntimePermission(manifestPermissions, 1212);   //handled
by OnRequestPermissionResult     SetLength(manifestPermissions, 1); 
 end;end; procedure TfrmMain.frmMainRequestPermissionResult(Sender:
TObject;  requestCode: integer; manifestPermission: string; 
grantResult: TManifestPermissionResult);begincase requestCode of   
1212:begin           if grantResult = PERMISSION_GRANTED  then       
  begin              //ShowMessage('Success! ['+manifestPermission+']
Permission granted!!! ' );               if manifestPermission =
'android.permission.READ_PHONE_STATE' then               
 showmessage('read_call_state_ok');            end         
else//PERMISSION_DENIED          begin             
ShowMessage('Sorry... ['+manifestPermission+'] permission not
granted... ' );          end;       end;  end;end;  procedure
TfrmMain.jTelephonyManager1CallStateChanged(Sender: TObject;  state:
TTelephonyCallState; phoneNumber: string);beginif state=csIdle then 
 showmessage('csIdle');if state=csRinging then 
 showmessage('pause');if state=csOffHook then 
 showmessage('start')end; 
The application is successfully compiled and installed on the phone.
But when I receive an incoming call, not one of the
TTelephonyCallState events does not work.

Why?

Hi, RDL!

finally!

Now demo "AppTelephonyManagerDemo1" can handle
"incoming call"  when the app is in background....

You,  can try the demo "AppBroadcastReceiverDemo2",  too!

Thank you!
