Click “Settings” from the left horizontal menu options available in the app dashboard section and select Basic.

Select “Add platform” available at the bottom.

Select “Android” from the options shown in the dialog box.

We need to update 3 Fields:

Enter your application ID you have given in your build.gradle(Module: app) file.

Class Name

Your class name is {Your application ID}.MainActivity

Key Hashes

To generate a key hash, open your terminal/command prompt and enter the following code:

Enter “android” as the password. 

Copy the generated key hash and paste it. Select “Save Changes”

3. After exporting the APK file

Select “App Review” from the left vertical menu options. 

Toggle the control to “Yes” under Make Application Public?

Update the Key Hash:

Kindly follow this step after processing the instruction in this document.

Open your terminal and type:

keytool -exportcert -alias {alias name} -keystore {keystore path} | openssl sha1 -binary | openssl base64

Substitute {alias name} with the alias you have given and {keystore path} with the path to the key file you generated in this guide.
