Background Start Not Allowed for IntentService on Redmi Devices

Question

I'm encountering an issue with starting an IntentService from one application to another on a Redmi device. The problem occurs only on Redmi devices and is related to background restrictions.

Description:

I'm using IntentService, Handler, and Messenger for communication between two applications. When the target application is in a closed state, I attempt to trigger the IntentService and receive the following log message:

Background start not allowed: service Intent { cmp=com.example.project/.nonui.services.UploadDataService (has extras) } to com.example.project/.nonui.services.UploadDataService from pid=9276 uid=10620 pkg=com.example.project startFg?=true

This issue is specific to Redmi devices; the service works as expected on other devices.

Details:

• The IntentService is declared in the Android manifest.

• I am using min SDK version 26 and target SDK version 30.

• I am using a Foreground Service for handling intents.

• Background restrictions might be affecting the service on Redmi devices.

Additional Information:

• I have tried enabling the background autostart setting for the apps, but the issue persists when triggering the IntentService for the first time while the app is in a closed state.

• I've checked the device settings for battery optimization but haven't found a resolution.

• I am aware that Redmi devices might have additional background limitations or optimizations.

Questions:

1. How can I resolve the "Background start not allowed" issue on Redmi devices?

2. Are there any specific considerations for background services on Xiaomi devices with MIUI?

3. What steps can I take to ensure that the IntentService is triggered correctly even when the app is closed?
