Any clue about how to resolve and debug?
this is my env:
Mesibo AP = 2.7.0
Build tools = 29.0.0
compile SDK versions = 30
appid = com.project.bucynapp
Thanks!

Have you tried the custom scripts or mesibo webhook to debug the issue? Have you referred to the Troubleshooting section in the mesibo push-notification document?
https://mesibo.com/documentation/api/push-notifications/
Unless you post logs and steps you have taken, we have no clue what is happening.

How can I make Exoplayer2 run in background? (Kotlin)

I am a noob in Kotlin.
I've made a streaming music player using Exoplayer2.
For running this music player in background, I tried to bind activity to service.
But it is not working.
I dont know why this player is stopped outside the app even though i add the foreground service.
Can anybody help me? :(

In order to start the foreground service, you will need a notification shown within 5 seconds of starting it. Check the following guide in the android documentation: https://developer.android.com/guide/topics/media-apps/audio-app/building-a-mediabrowserservice#mediastyle-notifications

How to save a new user if the entered details are new and load an existing user if the credentials exist using an SQLitedatabase?

I would like to create and store new users also update the existing users in the following code
What code needs to be added to strore new users in a SQLitedatabase
