KastriFree has long been deprecated, in preference to Kastri.

 

Which parts of it are you using, exactly?

In that report, it shows the entire stack trace for when the error occurs - is it the same for yours? As I said earlier:

You have not answered this part:

Meaning which version was used to compile the app where the problem is happening.

Regardless, are you able to reproduce the issue (RSP-23962) using the same steps as in the report? If so, please indicate what device(s) this is happening on.

I use delphi 12.2 patch 1. I test more and more but i cannot reproduce.

 

I made a small test example for the permission request for the device location. I am currently working with android. The project uses scripgate and a web browser. Library that allows you to make calls between web browser and delphi code. I press the load button and the page with a link is loaded. Pressing this link calls a function that returns the gps coordinates of the device if the location is activated. Should the activation of the locator LocationSensor1.Active := True; be done exclusively in the permission request? If I try to execute LocationSensor1.Active := True; simply in the create form if I am using the app and suddenly the connection is lost I close it and reopen it the application does not open crashing. Is it correct to ask for permissions in this way and activating the sensor in the create form or formshow after requesting permissions? i attached the sample project and scripgate library to test.

 

In kastri is there the way to detect the status of localization like connection status change? I would to like to detect the change of (Localization on/off) and then activate the TLocationSensor.

 

Thank you
