Android Testing in Headless Emulator
 When testing Android applications you have to rely on running the tests in the emulator or a device attached to your computer. However, if you want to follow a continuous integration workflow for Android development, you might need a headless emulator that runs in a non-graphical environment. For instance, I have been using  Travis CI  and Gradle for automating Android builds .     To completely avoid showing the emulator interface (headless emulator) you need to start the emulator with some options in your terminal.   First, you can create an specific Android AVD as follows:      1  android  create  avd  -- force  - n  test  - t  android - 17  -- abi  armeabi - v7a        Then, to run the headless emulator:     1  emulator  - avd  test  - no - skin  - no - audio  - no - window       The '-no-skin' option removes the emulator buttons such as the home and other hardware keyboard buttons.
