./gradlew assembleDebug

  2. Connect your phone (USB debugging enabled) and verify connection:
  ./android_studio_install_path/platform-tools/adb devices

  3. Install the APK:
  ./android_studio_install_path/platform-tools/adb install app/build/outputs/apk/debug/app-debug.apk

  Or you can combine build + install in one step:
  ./gradlew installDebug

  This requires your phone to be connected with USB debugging enabled in Developer Options.
