How to enable automated SMS verification when creating an e-commerce application (Step by Guide)
Are you an entrepreneur or beginner who wants to build your Android mobile app with an SMS verification feature? This mobile app development guide will help you add an SMS verification feature to your mobile app development plan?
In this Android application tutorial, we have shared a step-by-step process to enable automatic SMS verification using the SMS Retriever API on the Android mobile app. Before that, let us first understand what the SMS verification process is?
What is the SMS verification process?
When users on the Android platform need to log in to e-commerce or finance or shopping-related app, they need to enter the mobile number to get OTP. Then they have to copy the verification code received via SMS, go to the application and enter that code to log in successfully.
To overcome this problematic process, Google has introduced a news center function that automatically retrieves the verification code sent via SMS within an application.
How to include an automatic SMS verification feature in your E-Commerce app?
The aim of creating this SMS Verification Demo is to allow the Android app to detect and verify the verification code sent to the user's smart phone using the SMS Retriever API. It is useful to get the verification code directly from the mobile phone.
After Google introduced an automated SMS verification feature, they discovered some instances of mobile data access. Using the SMS verification feature, some Android apps will access users' call logs and SMS logs in an unauthorized way. Because of this vital data protection issue, Google may have to drop this feature for a while.
To provide the same functionality more securely, Google has recently made some important changes to its policy by restricting access permissions. Now, Android users will choose the app they want to access their call logs or SMS logs. This way, authorized applications can send OTP to the mobile phone to access the records and verify automatically via the SMS Retriever API. Therefore, the user does not need to copy and paste the code each time manually. So, let us follow these given steps to activate the code in the Android application.
Step 1. Add the file to the pro-level grade in the application:
Step 2. Activation 'com.google.android.gms: play-services-auth: 16.0.1'
Step 3. Activate 'com.google.android.gms: play-services-auth-api-phone: 16.0.0'
Step 4. Add the SMS receiver broadcast to the AndroidMenifest.xml file
Step 5. Record the broadcast for SMS recovery
Step 6. Start the SMS Receipt process to start the request for OTP
Step 7. Receive SMS format and verification code on My SMS Broadcast Receiver
Step 8. If you want to use hint Request Intent to retrieve the user's contact number from the phone
Step 9. Request for Number Hind by calling this method
Step 10. Get the selected number in on Activity Result
How to test the demo:
NOTE: From Server, SMS format should follow:-
- A) prefix: <#>
- B) content: Your OTP code is: 45678
- C) postfix: key hash from your key store
For example:
<#> Your OTP code is: 45678
Android Studio v3.3.1 with API 28 (Pie 9.0), SDK
