  • Private repos can be tested too 😃
  $ dryrun git@github.com:cesarferreira/android-helloworld.git
  • No need to cleanup after you test the library.

  • No need to wait for Android Studio to load.


Behaware that ANDROID_HOME needs to be set with the adb path:

  • MAC -> ANDROID_HOME=/usr/local/opt/android-sdk
  • Linux -> ANDROID_HOME=/usr/local/opt/android-sdk
  • Windows -> ANDROID_HOME="...sdk" In windows this ANDROID_HOME is not automatically created, see more in here

Additionally, on windows in order to use git commands, the following path should be on the environment variable

  • ...\Git\cmd

Alternative scenario (if you don't use dryrun)

  1. Find the github's repository url
  2. Click the download zip
  3. Extract the zip file
  4. Open Android Studio
  5. Import the project you just downloaded
  6. Sync gradle
  7. Run the project
  8. Choose the device you want to run
  9. Test all you want
  10. Delete the project folder and the zip file when you don't want it anymore


I welcome and encourage all pull requests. It usually will take me within 24-48 hours to respond to any issue or request. Here are some basic rules to follow to ensure timely addition of your request:

  1. Match coding style (braces, spacing, etc.) This is best achieved using CMD+Option+L (Reformat code) on Mac (not sure for Windows) with Android Studio defaults.
  2. If its a feature, bugfix, or anything please only change code to what you specify.
  3. Please keep PR titles easy to read and descriptive of changes, this will make them easier to merge :)
  4. Pull requests must be made against develop branch. Any other branch (unless specified by the maintainers) will get rejected.
  5. Check for existing issues first, before filing an issue.
  6. Have fun!
