Intent BOOT_COMPLETED not working on Huawei device

Question

I want to listen to APN Changes in my Android App.

Therefore I start a Service on android.intent.action.BOOT_COMPLETED. This Service starts a ContentObserver which listens to changes to content://telephony/carriers/preferapn.

I tested this setup on a few different devices (e.g. LG Spirit with Android 5.0, Samsung A3 with 6.0, Emulator Nexus5 with 7.0 and Huawei P9 Lite with 7.0)

On the Huawei phone onCreate of my Service is not called.

My other approach with android.intent.action.ANY_DATA_STATE in combination with a BroadcastReceiver which is registerd in the Manifest doesn't work either on this phone.

relevant parts of my manifest:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>  

...

<receiver android:name=".ConnectivityChangeReceiver">
    <intent-filter>
        <action android:name="android.intent.action.ANY_DATA_STATE" />
    </intent-filter>
</receiver>

<receiver android:name=".APNChangedServiceStarter" >
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <action android:name="android.intent.action.QUICKBOOT_POWERON" />
        <action android:name="com.htc.intent.action.QUICKBOOT_POWERON"/>
    </intent-filter>
</receiver>

<service android:name=".APNChangedService"></service>

Answer 1

Just for an update, Huawei changed the menu path in the Android 9 version.

On Huawei Mate 10 pro the way to get to this menu:
Settings -> Battery -> App launch -> Disable automatic management for your app.

A pop-up will appear, asking what you want to allow (all true by default). make sure that the first, Auto-launch is enabled

Huawei Phones have a built-in startup manager, it could be that the app is not yet enabled.

Go to Settings > All, and choose Startup manager. This program is used to manage startup apps on Android phone. Allow or disallow app to run automatically after the Huawei phone starts up.
