Colin Cross 532ae3bcfb Support LOCAL_RENDERSCRIPT_TARGET_API := current
Renderscript was using LOCAL_RENDERSCRIPT_TARGET_API := 0 to mean
current.  Use current instead, and check for it when comparing
if LOCAL_RENDERSCRIPT_TARGET_API >= 21.

Fixes an issue where LOCAL_RENDERSCRIPT_TARGET_API := 0 was being
treated as < 21, causing the renderscript resources to be passed
to aapt2:
out/target/common/obj/APPS/RSTestBackward_intermediates/flat-res/zip_res.flata.contents/raw/bc32: error: resource file cannot be a directory.

Bug: 79481102
Test: m java FORCE_AAPT2=true

Android Make Build System

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For an outdated reference on Android.mk files, see build-system.html.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.
