Does your App have the permission for it? I thought sth changed about in the last couple of years….
(Sorry if it is a dumb question)

Honestly, two years ago it worked perfectly, now if permits are needed, I don't know.

The aia you posted works in my Android 13 and provides current position correctly when using Companion 2.72. The gps part works fine.

However, the splash screen image is not working properly and I ignored it.

Just now I tried to use this app again via the companion. At first it still didn't work, but after repeated attempts to save my position; finally it managed to hook up to the GPS. P.s: The problem was not due to its malfunction; but to the fact that I was the one who expected the GPS to hook up instantly .. anyway my operating system is Android 11.

Android 11 is when Google introduced the concept of 'fused' provider. The app is selecting the Provider using Google's criteria whether to use cell phone tower or network data (WIFI) or the gps hardware to provide the location. When it does this it might be ignoring the LocationChanged block.

The app, written several years before the introduction of Android 11, should not be able save your current location unless the LocationSensor/gps hardware has a satellite fix or determines its coordinates. (You said previously that you 'can no longer get my current position) The LocationChanged block is supposed to prevent saving the location until the LocationSensor has determined that it provides the current latitude and longitude. The existing code seems to set the RememberButton.Enabled to true before it has a set of coordinates.

The if statement shown in the modified code I show here might allow the code to work correctly. It tries to make sure the button can not be pressed until proper coordinates are determined. It might remember for you to wait until coordinates exist. Coordinates are not available instantly. The app needs the correct data to save.

Glad your app is now working correctly.

Which blocks exactly? Can you provide a screenshot? Did you enable GPS? Does gps show in property AvailableProviders? Did to set provider to gps and lock the provider? Taifun

Yes exactly, see again my example project how to check available providers and how to set and lock the provider to gps [Screenshot_20241019_163548_DuckDuckGo] GPSsimple_2_Taifun.aia (13.1 KB) Taifun

A few years ago I created an app to eventually be able to share my location via WhatsApp or via SMS with some contact on my list (including to register the location for myself). It was one of my first projects while I learned AI2. I faced the problem of the 'delay' of the sensor... and the way found was to leave a message 'Wait' displayed on the screen that would only be changed after the latitude and longitude coordinates had finally read.

Perhaps you can enjoy this project to some of your needs and to understand how to deal with the sensor delay.
