CircleCI Espresso sample

Highlights:

• com.android.ddmlib.DdmPreferences.setTimeOut(60000) in the android.defaultConfig section of the build.gradle file (example)

• the circle.yml sets the ADB_INSTALL_TIMEOUT environment variable (example)

• there is a sleep 30 command before the screen unlock operation (example)

We also recommend that you set the TERM variable to dumb for better Gradle command-line output (example).
