Robolectric build-android.sh tutorial

Note: Based on Android documentation.

This tutorial will allow you to run the build-android.sh script in the Robolectric repository, resulting in the corresponding Android version's android-all jar.

1. Installing Repo

Repo is a tool that makes it easier to work with Git in the context of Android. For more information about Repo, see the Developing section.

To install Repo make sure you have a bin/ directory in your home directory and that it is included in your path:

$ mkdir ~/bin
$ PATH=~/bin:$PATH

Download the Repo tool and ensure that it is executable:

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

2. Initializing a Repo client

After installing Repo, set up your client to access the Android source repository:

Create an empty directory to hold your working files. If you're using MacOS, this has to be on a case-sensitive filesystem. Give it any name you like:

$ mkdir <WORKING_DIRECTORY>
$ cd <WORKING_DIRECTORY>

Configure git with your real name and email address. To use the Gerrit code-review tool, you will need an email address that is connected with a registered Google account. Make sure this is a live address at which you can receive messages. The name that you provide here will show up in attributions for your code submissions.

$ git config --global user.name "Your Name"
$ git config --global user.email "you@example.com"

Run repo init to bring down the latest version of Repo with all its most recent bug fixes. You must specify a URL for the manifest, which specifies where the various repositories included in the Android source will be placed within your working directory.

$ repo init -u https://android.googlesource.com/platform/manifest

To check out a branch other than master, specify it with -b. For a list of branches, see Source Code Tags and Builds. The source code must match one of those supported by Robolectric (unless a new API is being supported):

  • 4.1.2_r1 - Jelly Bean
  • 4.2.2_r1.2 - Jelly Bean MR1
  • 4.3_r2 - Jelly Bean MR2
  • 4.4_r1 - Kit Kat
  • 5.0.0_r2 - Lollipop
  • 5.1.1_r9 - Lollipop MR1
  • 6.0.1_r3 - Marshmallow
$ repo init -u https://android.googlesource.com/platform/manifest -b android-6.0.1_r3

A successful initialization will end with a message stating that Repo is initialized in your working directory. Your client directory should now contain a .repo directory where files such as the manifest will be kept.

3. Downloading the Android Source Tree

To pull down the Android source tree to your working directory from the repositories as specified in the default manifest, run

$ repo sync -c -j100

Beware this will take over an hour and will require 45+ Gigabytes of space. If you face download quota restrictions, try the Using Authentication section.

4. Grab dependencies

On Ubuntu run

$ sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
libgl1-mesa-dev libxml2-utils xsltproc unzip libswitch-perl

5. Set environment variables

$ export BUILD_ROOT=<Path to AOSP source directory>
$ export SIGNING_PASSWORD=<Passphrase for GPG signing key>
$ source build/envsetup.sh

6. Build AOSP

NOTE: For Kitkat and below Java 7 and 8 are not supported. Use Oracle JDK 6 instead.

For Jellybean 4.2 and below:

$ lunch generic_x86-eng
$ make -j8

For Jellybean 4.3 to Lollipop:

$ lunch aosp_x86-eng
$ make -j8

For Marshmallow and above:

$ tapas core-libart services services.accessibility telephony-common framework ext icu4j-icudata-jarjar
$ ANDROID_COMPILE_WITH_JACK=false make -j8

7. Run build-android.sh

(Optional) Signing Artifacts: The end of the script will prompt you to sign the new artifacts. You will be prompted a total of 4 times (once for each artifact). To make this easier, run this command beforehand:

$ gpg-agent --daemon

Finally, in your Robolectric directory run:

$ build-android.sh <android version> <robolectric sub-version>

For Robolectric version 6.0.1_r3-robolectric-0, android version would be 6.0.1_r3 and robolectric sub-version 0.
