Requirements

  • Python 3
  • Linux or macOS

Current and former contributors have used Ubuntu 18.04 and Ubuntu 20.04 along with Python 3.6.9 and 3.7.4.

Setting Up Environment and Dependencies

  1. Click on the Fork icon in the top right hand corner once you're logged into Github.
  2. Once it finishes loading, click on the green Code button. Copy git clone [email protected]:[your_username]/android-runner.git and then paste that into your terminal after navigating to the desired local development environment.
  3. Type cd android-runner to enter the framework's main directory. Now, add a remote tracker to the parent repository with git remote add upstream https://github.com/S2-group/android-runner. This is useful in case any major changes occur to the parent directory that may affect your project. git remote -vv should now show origin and upstream.
  4. Create a virtual environment: python3 -m venv /path/. This can be anywhere on your machine. Activate it with source /path/bin/activate.
  5. Install dependencies:
    1. Select your platform below:

      Linux

      Ubuntu 22.04 (command-line only)

      • Install JDK 11 sudo apt install openjdk-11-jre.
      • Download thesdkmanager from the latest "command line tools only" package available here and unzip the package to your $HOME directory.
      • Create a directory called android-sdk in your $HOME directory and move the unzipped cmdline-tools directory there.
      • In the directory cmdline-tools create a sub-directory called latest.
      • Move all the original contents from cmdline-tools into the newly created latest directory.
      • cd into cmdline-tools/latest/bin and run the following commands to install adb and monkeyrunner:
          ./sdkmanager "platform-tools"
    ./sdkmanager "build-tools;30.0.0"
      • Add the following to your .bashrc or .zshrc file:
          export PATH=$HOME/android-sdk/cmdline-tools/latest/bin:$PATH
    export PATH=$HOME/android-sdk/platform-tools:$PATH
    export PATH=$HOME/android-sdk/tools/bin:$PATH
      • Reload your .bashrc or .zshrc settings by running source ~/.bashrc or source ~/.zshrc
      • To verify if everything works correctly run adb --version. This should return its version number and install location. To do the same for Monkey Runner run monkeyrunner --version. This should return a Unrecognized argument: --version. but no other errors.
      • Install lxml using sudo apt install python3-lxml (assuming python3 is being used).

      Ubuntu 18.04

      • Android Debug Bridge (sudo apt install android-tools-adb)
      • Android SDK Tools (sudo apt install monkeyrunner)
      • JDK 11 (sudo apt install openjdk-11-jre)
        • See this for switching between java versions
      • lxml (sudo apt install python-lxml)

      Other

      • Download Android Studio from here.

      • Extract the archive, cd into its directory and install Android Studio by running ./bin/studio.sh

      • During the setup wizard Android Studio will ask you where you want to install the Android SDK. By default it is in /home/user/Android/Sdk

      • The Android SDK, including ADB and Monkey Runner, is now installed on your system. To access the Android tools directly via your shell (preferable) add the following to your .bashrc/.zshrc:

        export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools

      • Reload your .bashrc or .zshrc settings by running source ~/.bashrc or source ~/.zshrc

      • Since MonkeyRunner requires JDK 8 (not JDK 9) we need to install JDK 8: sudo apt install openjdk-8-jre.

        • Once JDK 8 is installed we need to actually set it as default. See here how to do that.

      • To verify if everything works correctly run adb --version. This should return its version number and install location. To do the same for Monkey Runner run monkeyrunner --version. This should return a Unrecognized argument: --version. but no other errors.

      • Install lxml using sudo apt install python-lxml.

      macOS

      • Make sure you have Homebrew installed
      • brew install --cask homebrew/cask-versions/adoptopenjdk8 android-sdk android-platform-tools
      • brew install libxml2
      • Run java -version, if you are running a different version than 1.8/8:
      • brew install jenv
        • Run /usr/libexec/java_home -V to see the location of your Java environments
        • Copy the location of your AdoptOpenJDK8 environment
        • Run jenv add <AdoptOpenJDK8_path>
        • Run jenv global 1.8
        • Restart terminal and verify your Java version with java -version, it should output openjdk version "1.8.0_265"
      • Verify that monkeyrunner works with monkeyrunner --version, it should output unrecognized argument and no other errors
    2. Within Android Runner's main directory
      • pip install -r requirements.txt
    3. For creating or editing unit tests to ensure pull request passes TravisCI
      • pip install pytest mock

Note: It is important that Monkeyrunner shares the same adb the experiment is using. Otherwise, there will be an adb restart and output may be tainted by the notification. You can specify the path to adb and/or Monkeyrunner in the experiment configuration file.

Note 2: The Batterystats, Trepn and Monsoon plugins have additional dependencies. Refer to the plugin READMEs for more information.

Before You Begin

It's important for us to make sure that any updates to the framework add value and that the updates adhere to the original goals of the framework. Before spending a lot of time making substantial changes, please raise an issue on Github so we're made aware of the changes you'd like to implement. We'll provide feedback to inform you whether we think it's viable.

Environment

  • Your forked repository will come with one branch, called master.
  • Create additional branches for experiments and/or development with git branch branch_name.
  • To update your forked repo with parent repo, git checkout master and type git fetch upstream followed by git rebase upstream/master so your local work is put on top of any changes made to the parent repo.
    • Note, this may mean you'll have to stash whatever you were working on. In this case, git stash save "message" before git checkout master.
  • Once master has been updated, checkout the other branches to update with git merge master.
  • Then, git stash pop stash@{#} to continue working on changes.

Making Changes to Your Forked Repository

Commits

Any commits should contain logically similar changes. Commit messages (git commit -m "[text]") should be informative but also concise. Good commits make changes easier to review later. To limit the number of commits, use git rebase to squash the commits down to a more reasonable number.

Plugins

If you're editing an existing plugin or adding a new one, there's an automated test called plugintest in examples that will ensure the plugin adheres to the requirements of the framework. To execute it, type: python3 android-runner android-runner/examples/plugintest/config.json.

Submitting a Pull Request

Pull requests should be made from secondary branches (ie, not master). Also make sure the branch is not behind in commits compared to master. Any changes that need to be made while a pull request is still pending review should be made on a third branch to prevent polluting the pull request with other changes if they're not relevant.

When a pull request is submitted, a number of automated tests are performed on the TravisCI platform and with SonarCloud. TravisCI runs coverage analysis to confirm that all major components in the framework have associated unit tests in tests/unit/. In other words, you'll need to add unit tests for new methods, plugins or other functionality improvements. For an expedited review process, run pytest in your local environment before submitting a pull request. You can execute these tests in the android-runner directory with: py.test [options] tests/unit. It's also possible to run py.test with a specific module in tests/unit/. Don't forget to remove debugging statements before submitting.

To execute the test suite make sure you have installed coverage, pytest and mock either globally or in your virtual environment. You can then run (assuming Python3):

python -m coverage run -m py.test tests/unit/

To then check the code coverage and report missing lines run:

python -m coverage report -m

Communication

The best way to communicate with the Android Runner team is through:

  • Opening a GitHub issue
  • Slack
  • Canvas

Debugging Tips

pdb is a good library to import if you experience issues that may be hard to resolve with print statements.
