[Android-tools-devel] Android N source code now available

[殷啟聰]

Hi Chirayu,

Surprised that the tags are pushed in just several days! :)

Now that the source codes are there, maybe we can finish updating all
packages to 7.0 before Stretch freeze (Q3 2016, or 5 November? See
<https://wiki.debian.org/DebianStretch>). So far I can think of
several changes to the packages, albeit the overall packaging won't
change too much:

Removal of pkg:android-platform-build-headers
=============================================

Since Android 7, "AndroidConfig.h" have been removed (see
<https://android.googlesource.com/platform/build/+/43146118aab8e15e8ed4f859106d8ddccc06d21b>).
Judging from the Git log, looks like AOSP guys have been planning to
get rid of these files for a long time. Now that these files are
removed, pkg:android-platform-build-headers can be removed as well,
and all other packages should stop including these headers. Thus, we
can also get rid of the circular dependency between
src:android-platform-build and src:android-platform-system-core. As a
result, src:android-platform-build no longer need to have staged
upload.

Separation of AIDL as an Independent Package
============================================

Since Android 7, AIDL is separated as an independent project
<https://android.googlesource.com/platform/system/tools/aidl>. AIDL in
Android 6 does depend on any libraries, so it will be relatively easy
to deal with. The tricky part is the transition in Debian.

Currently AIDL is built in src:android-platform-frameworks-base and
used by src:android-platform-$version. We can remove the AIDL package
in src:android-platform-frameworks-base and upload it, then upload
src:android-platform-system-tools-aidl, then the rest are fine.

Time to Re-enable ARM Builds!
=============================

A guy from Debian LAVA complained about removing ARM builds of ADB and
fastboot at the removal bug <https://bugs.debian.org/817823>. And I am
also thinking about buy ARM laptops in the future, it would be a great
pity if Android Tools won't be available on those platforms. Chirayu
has been using ARM64 Debian, he can help as well.

We gave up the support of ARM and MIPS builds because libbacktrace
FTBFS on MIPS and libunwind FTBFS on ARM64. Several hours ago I fixed
the FTBFS of libunwind, and it already build fine on armel and armhf,
why not build them? Now I have setup ARM and MIPS QEMU environments on
my machine, and buildd builds all architectures for us, it won't be a
burden to support them.

If we don't enable the builds for ARM and MIPS for the reason that
"Google officially supports the SDK on x86", well we can't really
enable the amd64 build either because Google only officially supports
the SDK on 32-bit x86.

We still won't consider building the SDK on other architectures like
PowerPC or Sparc because Google only supports the Android system on
x86, ARM and MIPS, and libunwind doesn't have the corresponding source
files on other platforms and therefore can't be built.

Looking forward to seeing Android SDK on MIPS. Android SDK on ARM and
MIPS, this is one of the attracting points of android-tools in Debian!

Cheers,
Kai-Chung Yan
