Impossible to start NotificationListener

[dughy]

after I compile the android project with Android studio, I can't activate notification listener on the phone, but work on simulator.
I'm new in android project so I don't know where is the problem, I need help!!

I try to search device before activation of notification to see ble work but no device found... so my problem I bigger then before

Hi, I am not sure what type of device you use, could you provide some more information about it?

i have android 12 device and I try to connect with your Arduino sketch, but modified with display code elimination (I have a esp32-s3 with 7inch display and use lvgl library)

I just tried it on one of my phones with Android 12, and the program works well, have you tried it on different devices? Also, you could try to delete the bleService code inside of the notificationService and see if the bleService keeps shutdown after the notification service starts

i trust your code work, but I suppose problem is related to the creation of apk... I haven't experience with android, so it's possible to have an apk to test?
sorry I realise now it's android 13

Hello, sorry I did not receive the notification from your post, Yes you can download the compiled APK from the project folder

Hi, I just uploaded a new one with new code, but anyway, I only tested it with the emulator since I do not have any real devices with Android 14

I could not reproduce this issue, I just tested it on the physical device OnePlus PHP110 with Android 14, and it works OK, maybe you can download the project and try it on Android Studio and see what shows up in the prompt
