I set up broadcast reciever for restarting my foreground service after reboot.
I have two devices and it works on Meizu M1 note (android 5.1) but doesn't work on Samsung A8 (android 9). Looking for reason in restrictions after Oreo and seems like it ok, but just in case https://developer.android.com/about/versions/oreo/background.html
On the second one broadcast reciever called, but service not started after reboot.
Service tracks location and uses startForeground() with Notification for correct work.
Also tried to add Worker to restart service after reboot, but seems like work missing after that.
Please, geve any suggestions why my reciever doesn't run service.
Thanks.

Following steps helped me solve it:
Remove and reinstall app
Change manifest according to this
<receiver android:name="com.foxminded.tracker.ui.broadcast.ServiceRestart"
android:exported="true"
android:enabled="true">
<intent-filter>
<action android:name="restartService" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.LOCKED_BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
Here added "android.intent.action.LOCKED_BOOT_COMPLETED" and android:exported="true" android:enabled="true"
