Proglem: Create custom Android App which will never be killed by the platform.
Given a Dialer app (or a phone-app), for making calls on Android Phone, is there a way to similarly create custom app and make it a system app, so that Android always keep it running?
In other words, the problem we have is to deploy an app which will never be killed by AOSP due to lack of resources or anything similar, which is what I think android does for Dialer and some other system apps/services.
Possible helpful hint: The device will always have power supply, as it is not a phone/tablet but rather a custom device running custom AOSP.
