 Before running or building the app, update the dependencies for the desired flavor:
 ```
-# scripts/apply_flavor_play.sh

 ```
 
 To build the project, create a file named `<app dir>/android/key.properties`. It should contain a reference to a keystore for app signing, and other necessary credentials. See [key_template.properties](https://github.com/deckerst/aves/blob/develop/android/key_template.properties) for the expected keys.
