Background execution not allowed receiving Intent act=androidbluetoothadapteractionSTATE_CHANGED flg=0x4000010 has extras to comchinamobilemiddlewareguidecomshcmccchinamobilebroadcastDeviceStateRece

This error message indicates that the app "com.chinamobile.middleware.guide" is not allowed to receive the "android.bluetooth.adapter.action.STATE_CHANGED" intent in the background.

Starting from Android 8.0 (API level 26), background execution restrictions were introduced to improve battery life and overall system performance. As a result, apps are limited in their ability to receive certain broadcast intents while running in the background.

To resolve this issue, you can either request the necessary permission to receive the intent in the background or modify your app's behavior to handle the intent while the app is in the foreground.

If you need to receive this intent while your app is in the background, you can request the "android.permission.RECEIVE_BOOT_COMPLETED" permission in your app's manifest file. However, note that this permission is only granted to system apps, so it may not be applicable to your situation.

Alternatively, if your app can handle the intent while it is in the foreground, you can register the receiver dynamically in your activity or service using the registerReceiver() method. This way, the receiver will only be active while your app is running.

Keep in mind that handling the intent in the foreground may still be subject to certain restrictions, such as when the device is in Doze mode or App Standby. In these cases, you may need to consider using foreground services or other techniques to ensure your app can receive the intent reliably.

Overall, it is important to understand and comply with Android's background execution restrictions to ensure your app functions correctly and efficiently on all devices.
