I am trying to compile your app with fresh android studio installation.

First I need to update kotlin to 1.3.21 and then I need to change the link from jre to jdk.

After I run that it still doesnt work.

Can you help the noob :D

I have read the complete article. I followed it an created an app. The main issue I'm facing is that when app is destroyed the InCallService doesn't launch the CallActivity that was created to handle the calls on some devices. I'm using Infinix device with Android version 11. I'm trying to launch my custom CallActivity when a new call is added to the device. it work fine if the application is in foreground or in background but it stop working when the app is destroyed. If the app is destroyed the default call activity is launched instead of the custom CallActivity that I created. Also on some devices even if the app is destroyed the custom CallActivity is launched but the TextToSpeech api doesn't work.

I managed to write a code to replace default phone app as explained in this repository. It is working only when screen is turned on. If screen is turned off, I can only hear ring tone, screen does not turn on. If I turn on screen manually, I can't see any call interface (not mine or not system default phone app. So I can't handle answer that call). How can I turn on screen when phone rings? I've tried several solutions about how to turn on screen, but no one is working in this case.

Any suggestions?
