Update minimum supported targetSdk to 28 This change will cause a dismissable warning message to display indicating the app is targeting a low targetSdkVersion. Previously this message was displayed for apps targeting < 23. The eventual goal is to move this to 29, but still working through some failed CTS tests. Updating first to 28, and then will follow up with an update to 29. Bringing this to 29 would be in line with trailing by 4 major releases.

This is the Makefile-based portion of the Android Build System.
For documentation on how to run a build, see Usage.txt
For a list of behavioral changes useful for Android.mk writers see Changes.md
For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.
This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
