    The verification message is sent to your application automatically for processing, on condition that the message follows a predefined format which ensures that the message was intended for your app. Message format requirements Be no longer than bytes Contain a one-time code that the client sends back to your server to complete the verification flow Include an character hash string that identifies your app When should it be used?

    Android requires that all APKs be digitally signed with a certificate before they are installed on a device or updated. The signing process is done using a keystore file.

    During development, you will probably be using the debug build type signed by default with a well known and insecure debug keystore. But the app that end-users download from Google Play is signed with a different certificate. Google Play uses it to generate and serve optimized APKs for each device configuration. Since those APKs are generated by Google, you also need to let Google take care of the signing by using Play app signing.

    It signs the final APK for you with a different certificate that Google manages and it can be found in the Play Console.

    To calculate the hash string: Download the Play app signing certificate in. If you use it, you can upload the app to Internal test track and download it from Google Play using a testing account. That way you download an app with the same certificate as end-users. Send a test SMS message Now comes the time to test your implementation and send a test message with a verification code and the calculated hash string.

    Android emulators come with the convenient option to send SMS messages to them. The most challenging part is arguably calculating the hash string.
