Testing an android app for restart functionality

Question

I am trying to develop an Android App that, though having an Activity, needs to run in the background as a service. The app needs to start up automatically after rebooting the phone/device.

My question is HOW to troubleshoot such requirements, since the LogCat gets disconnected when the phone is rebooted, even using "adb shell broadcast -am android.intent.action.BOOT_COMPLETED" on a connected phone. (Though possible on an emulator, I dont feel like it is able to properly replicate real-world scenarios). I would like to be able to see the Logcat messages after device restarts, thus allowing me to troubleshoot ANRs and app crashes during reboot.

Any pointers would be appreciated.

Answer 1

Based on this link, I understand the closest we can get to debugging reboot errors is to use

adb logcat -v time > <localfile>

or

adb bugreport

Both of these options may not be the cleanest ways to pinpoint the issue, but atleast something is better than nothing.
