This changes the default Java language level from 8 to 9, i.e. javac invocations now use -source 1.9 -target 1.9. The environment variable EXPERIMENTAL_JAVA_LANGUAGE_LEVEL_9=false is added to switch back to the language level 8 behaviour. (Previously, setting that variable to true was required to opt in to language level 9.) Test: make droid java tests cts docs Test: javap -v <some class file in output> | grep 'major version' (reports 53, for classes from 'benchmarks' which is in Android.bp and 'ahat' which is in Android.mk) Test: make RunBluetoothRoboTests RunCarSettingsLibRoboTests (two main flavours of robolectric) Test: make cts && cts-tradefed help Test: atest CtsLibcoreTestCases (reasonably low-level device tests) Test: atest CtsHostTzDataTests (arbitrary host test) Bug: 115604102 Change-Id: I06c4adb3861db82f4804ac9322a131067f395b4e Merged-In: I13b2ff61c6423ad99464e0a4d2b1bedfd8ae1080 |

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For an outdated reference on Android.mk files, see build-system.html.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