Running broadcast tests from the app does not accurately verifies
whether the broadcasts can be delivered when the app is not running in
the foreground, which is why we are running the test.
The only sane way to verify broadcasts is to trigger the broadcast test
directly from the daemon on boot complete. If it is not deliverable,
then activity mode shall be chosen.
In the meantime, cleanup AndroidManifest.xml
- increase SignBoot bootimg header version maximum from 4 to 8 (upstream AOSP is already at 3) and make a variable for future ease
- hdr read size of 1024 bytes was too small as hdr_v1 and hdr_v2 have increased the used header page areas to 1632 and 1648 bytes, respectively, so raise this to the minimum page size of 2048 and also make a variable for future ease
- do not return "not signed" for all caught exceptions, show StackTrace for future debugging then still return false for script purposes
- correct "test keys" boot image signing strings (scripts and app) to "verity keys"
Settings are now only on home screen as it directly relates to what user might want to do. It is highly unlikely that they would jump from any other screen to settings.
Log is no longer main destination as it's not used very widely; it's been moved to Superuser screen. This screen now encapsulates all root-related stuff.
Home screen is now strictly info-based, except install buttons, of course.
On API 23+, the platform unifies the way to handle drawable
resources across processes: all drawables can be passed via Icon.
This allows us to send raw bitmap to the system without the need to
specify a resource ID. This means that we are allowed to NOT include
these drawable resources within our stub APK, since our full APK can
draw the images programmatically and send raw bitmaps to the system.
