-Cordova will generate a new Android project in the platforms/android directory. Install the built apk by `platforms/android/app/build/outputs/apk/<processor>/debug/app-<processor>-debug.apk` (You will need to find the corresponding `<processor>` architecture if you choose to install the apk on a device).

-### Building for Android with Docker

-A Docker image with all pre-requisites for Android builds is included. To build:
-
-- Install dependencies with `./tools/build/build.sh npm ci`
-- Then build with `./tools/build/build.sh npm run action gulp -- build android`
+Cordova will generate a new Android project in the `client/platforms/android` directory. You can find the built apk at: `client/platforms/android/app/build/outputs/apk/debug/app-debug.apk`.
 
 ### To install the APK
 
 - Connect an Android device and enable [USB debugging](https://developer.android.com/studio/debug/dev-options.html#enable).
 - Build the app, with `npm run action client/src/cordova/build android`
-- From the project root, run: `adb install -r -d platforms/android/app/build/outputs/apk/<processor>/debug/app-<processor>-debug.apk`
