Replicant

h1. Build the Android Development Tools for Eclipse (ADT) with Replicant 4.2

h2. Principle of operation

The [[ReplicantSourceCode|Android 4.2 source code]] ships a @sdk/eclipse/@ directory with ADT build scripts.

The build script will also download Eclipse 3.6.2 files as build dependencies.

Note: as of 2015-07, ADT is "deprecated":http://android-developers.blogspot.fr/2015/06/an-update-on-eclipse-android-developer.html in favor of Android Studio, based on IntelliJ. 

h2. Recreate matching build environment

Replicant 4.2 is based on CyanogenMod 10.1 which is based on AOSP 4.2.2, released 2013-02.

The build environment used by NDK release managers should be Ubuntu LTS 10.04.

To recreate it easily with LXC, follow:

* [[BuildEnvironments#Trisquel-41-Taranis-based-on-Ubuntu-1004-Lucid-with-LXC|Trisquel 4.1 Taranis (based on Ubuntu 10.04) with LXC]]

* [[BuildEnvironments#Non-privileged-user-setup|Non-privileged user setup]]

h2. Build dependencies

<pre>

# Based on https://web.archive.org/web/20121201011547/http://source.android.com/source/initializing.html

# git recompiled manually, mingw32 dropped

apt-get install gnupg flex bison gperf build-essential \

  zip curl zlib1g-dev libc6-dev lib32ncurses5-dev ia32-libs \

  x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev \

  libgl1-mesa-dev g++-multilib python-markdown \

  libxml2-utils xsltproc

h2. Preparing the sources

Based on [[ReplicantSourceCode]] with additional configuration.

Login as user @replicant@ and:

<pre>

mkdir ~/tools/

cd ~/tools/

wget http://commondatastorage.googleapis.com/git-repo-downloads/repo

chmod a+x repo

cd ~

cat <<EOF >> ~/.bashrc

export USE_CCACHE=1

EOF

# Avoid prompts

git config --global user.email "you@example.com"

git config --global user.name "Your Name"

git config --global color.ui true

mkdir replicant-4.2/

cd replicant-4.2/

../tools/repo init -u git://git.replicant.us/manifest.git -b replicant-4.2

../tools/repo sync -j4 

# > 1h, 27GB (inc. 17GB .repo)

</pre>

h2. Building ADT 21

<pre>

. build/envsetup.sh

lunch sdk-eng

cd sdk/eclipse/

# Complies with setup_eclipse.sh and fix download URL

sudo mkdir -p /buildbot/eclipse-android

sudo chown replicant /buildbot/eclipse-android

sed -i -e '/eclipse-rcp-helios-SR2/ s/download.eclipse.org/archive.eclipse.org/' \

  scripts/setup_eclipse.sh

# Note: I tried with 'apt-get install eclipse-rcp eclipse-pde' and ECLIPSE_HOME=/usr/lib/eclipse

# but it lacks org.eclipse.wst.* plugins aka eclipse-wtp-xmltools

scripts/build_server.sh ~/adt

# ~1h with 4 cores, 32GB (inc. 17GB .repo), 1GB .ccache

</pre>

The ADK release is in @~/adt/android-eclipse-v201507252158.zip@ :)

h2. Testing

See the nice Eclipse tutorial at [[SDK#Usage-guides]].

h2. TODOs

* warning on installation, maybe we can sign the package:

<pre>

Warning: You are installing software that contains unsigned content.

The authenticity or validity of this software cannot be established. Do

you want to continue with the installation?

</pre>

* Note: error in Eclipse 3.8.1 in the layout edition view. Needs testing with an older Eclipse:

<pre>

This version of the rendering library is more recent than your version of ADT plug-in. Please update ADT plug-in

</pre>

* Do we rely on prebuilt/prebuilts dirs?
