Why Android SDK in Debian? ● The SDK from Google is non-free [1]

The current goal ● A minimalist command-line build environment

The current goal ● A minimalist command-line build environment ● Along with… ○ NDK (via “contrib” installer) ○ Maven repo of Support Library ○ Maven repo of Google libraries (via “contrib” installer)

Difficulties we faced ● Crazy inconsistent versioning ○ SDK version 24.0.2 ○ Build-tools version 23.0.2 ○ Platform-tools version 23.0.0 ○ API Level 23 ○ Android version 6.0.1

Difficulties we faced ● Circular dependencies

Difficulties we faced ● Circular dependencies android-platform-system-core android-platform-system-extras adb libf2fs_utils fastboot libext4_utils liblog libXXX...

Difficulties we faced ● Circular dependencies android-platform-system-core android-platform-system-extras Build-profiles solve this!

Difficulties we faced ● Building some components needs multiple upstream repos ○ “android.jar” needs 4 repos

Difficulties we faced ● Building some components needs multiple upstream repos ○ “android.jar” needs 4 repos ● No usable build system ○ Handwritten Makefile according to “Android.mk” ○ Perhaps “Android.mk” can be interpreted

Difficulties we faced ● Building some components needs multiple upstream repos ○ “android.jar” needs 4 repos ● No usable build system ○ Handwritten Makefile according to “Android.mk” ○ Perhaps “Android.mk” can be interpreted ● Some repos have C/C++ as well as Java projects

Difficulties we faced ● Building some components needs multiple upstream repos ○ “android.jar” needs 4 repos ● No usable build system ○ Handwritten Makefile according to “Android.mk” ○ Perhaps “Android.mk” can be interpreted ● Some repos have C/C++ as well as Java projects ● Google forked quite a lot of things ○ Doclava, libunwind, libselinux and even OpenSSL

The progress so far ● Updated Gradle to 2.x

The progress so far ● Updated Gradle to 2.x ● The Gradle plugin

The progress so far ● Updated Gradle to 2.x ● The Gradle plugin ● The Android Platform “android.jar” almost done

The progress so far ● Platform-tools ○ adb ☑ ○ dmtracedump ☑ ○ etc1tool ☑ ○ fastboot ☑ ○ hprof-conv ☑ ○ systrace.py
