Integration

Integration with the PayU OTP Parser SDK in 3 steps:

1. Include the SDK in your application.

2. Initiate the SDK.

3. Override these callbacks

Include the SDK in your Application

Add below dependency in the application's build.gradle.

implementation 'in.payu:native-otp-reader:1.1.3'

Initiate the SDK

Java

OtpParser otpParser = OtpParser.Companion.getInstance(ComponentActivity activity);
otpParser.startListening(OtpCallback otpCallback)
    
    OtpCallback otpCallback = new OtpCallback() {
           @Override
           public void onOtpReceived(@NotNull String otp) {
             //When user gets the OTP  
           }

           @Override
           public void onUserDenied() {
//User user denied the permission
           }
       };

Kotlin

 val otpParser = OtpParser.getInstance(activity: ComponentActivity)
 otpParser?.startListening(otpCallback: OtpCallback)
 
   val otpCallback= object:  OtpCallback {
            override fun onOtpReceived(otp: String) {
         //When user gets the OTP  
               }

            override fun onUserDenied() {
           //User user denied the permission
             }

        }
 

Override these Callbacks

You need to override these ActivityCompat callbacks and call OtpParser methods.

Java

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
   
             otpParser.onRequestPermissionsResult(requestCode, permissions, grantResults);
//calling OtpParser onRequestPermissionsResult
   }
     
     @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
      
          otpParser.onActivityResult(requestCode, resultCode, data);
        //calling OtpParser onActivityResult

    }

   

Kotlin

  override fun onRequestPermissionsResult(
        requestCode: Int,
        permissions: Array<out String>,
        grantResults: IntArray
    ) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)
       
         otpParser?.onRequestPermissionsResult(requestCode, permissions, grantResults)
   //calling OtpParser onRequestPermissionsResult
     }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
       
         otpParser?.onActivityResult(requestCode,resultCode,data)
    //calling OtpParser onActivityResult
    }
