 # Chromoting Android Hacking
 
 This guide, which is meant to accompany the
 [compilation guide](chromoting_build_instructions.md), explains the process of
 viewing the logs and debugging the CRD Android client. I'll assume you've
 already built the APK as described in the aforementioned guide, that you're in
 the `src/` directory, and that your binary is at
 `out/Release/apks/Chromoting.apk`. Additionally, you should have installed the
 app on at least one (still) connected device.

 Note that if you have multiple devices connected, you must export
 `ANDROID_SERIAL` to select one; set it to the serial number of the desired
 device as output by `$ adb devices`.
