For all your App SigningReport needs!

As I make different mobile apps based on React Native (bare), I like to use Medium as a place to write about problems that may not be talked about much on sites like StackOverflow, Github, and others. The purpose of this is two-fold, i.e., one — for future reference since I will probably stick to this tech stack a lot, and two — for the benefit of other developers out there who face similar predicaments as I did when developing React Native applications.

Instructions:

• In your terminal, enter the command cd android && ./gradlew signingReport
• The result will display the debug and release version SHA1. Choose the corresponding version appropriately.
• Then you can go to Google Developer Console and generate the OAuth Client ID for Android.
• Copy the ID generated and save it in a .env file at the root of your React Native app.

Side-note:

To use the values stored inside your.env file, you need to have thereact-native-config package installed, either via npm or yarn.
