[AOSP (Pixel, Nexus...)]Take the following actions when your app is not working

AOSP (Pixel, Nexus...)
Take the following actions when your app is not working

There’s a special option in Settings > Apps > Your app > Advanced > Battery > Background restrictions. If users accidentally enable this option it will break their apps. And users do enable that option!

Pie and pre-Pie

If you see background processing issues, overall it is a good idea to make your app not battery optimized to ensure it gets the freedom it needs to perform in the background.

For that:

1. Go to Settings > Apps > Your app > Advanced > Battery > Battery optimization
2. Change view to All apps
3. Search for your app
4. Choose Not optimized

Android O

Make sure Settings > Apps > Your app > Advanced > Battery > Background limitations is not enabled. If the app is not yet optimized for Oreo API level it will break their background processing.

If all fails

If all fails you can turn doze mode completely off in Settings > Developer options. (If you don’t know how to enable developer options, Google should help.)
