Usage (How to verify phone number using Voice OTP)

Step 4. implement VerificationInterface in Activity or fragment and implement the methods.

public class MainActivity extends AppCompatActivity implements View.OnClickListener,VerificationInterface{

    private EditText phonenumberEt;
    private Button btnOtpVoice;
    private MobtextingService mobtextingService;
    private String sixDigitOTP;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        phonenumberEt=(EditText)findViewById(R.id.phonenumberEt);
        btnOtpVoice=(Button)findViewById(R.id.btnOtpVoice);
        
        //craeate the instance of MobtextingService
        mobtextingService=new MobtextingService(getBaseContext());
        
        
    }
    
    @Override
    public void onClick(View view) {
        switch (btnOtpVoice.getId()){
            case R.id.btnOtpVoice:
                if(phonenumberEt.getText().toString().equals("")){
                    Toast.makeText(getBaseContext(), "Enter Mobile number", Toast.LENGTH_SHORT).show();
                }else {
                    sixDigitOTP = String.valueOf(generateSixDigitRandomNumber());
                    mobtextingService.getVoiceOTP("7250705072", sixDigitOTP, "7488792140", MainActivity.this);
                }
            break;
        }
    }
    
     /**
     * generate Six Digit OTP
     * @return
     */
    public int generateSixDigitRandomNumber(){
        Random random=new Random();
        int sixDigit=100000+ random.nextInt(800000);
        return sixDigit;
    }
    
    @Override
    public void onSuccesResponse(ServerResponse serverResponse) {
        
        //check the response code with 200 and status==true
        if(serverResponse.isStatus()&&serverResponse.getResponse_code()==200){
        
        //pass the generated six digit OTP code to VerifyActivity
            Intent verifyActivityIntent=new Intent(getBaseContext(),VerificationActivity.class);
            verifyActivityIntent.putExtra("otp",sixDigitOTP);
            startActivity(verifyActivityIntent);
        
        }else{
            Log.d("TAG",serverResponse.getMessage()+"   "+serverResponse.getResponse_code());
        }
    }
    
    @Override
    public void onErrorResponse(ServerResponse serverResponse) {
        
    }
 }

Step 5. verify your generated six digit OTP with entered OTP by user

public class VerificationActivity extends AppCompatActivity implements View.OnClickListener {
   private String otpFromActivity;
   private EditText editOtp;
   private Button btnVerify;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_verification);


       editOtp = (EditText) findViewById(R.id.editOtp);
       btnVerify = (Button) findViewById(R.id.btnVerify);

       //get the six digit OTP from previous actvity
       Bundle bundle = getIntent().getExtras();
       if (bundle != null) {
           otpFromActivity = bundle.getString("otp");
       }


   }

   @Override
   public void onClick(View view) {
       switch (view.getId()) {
           case R.id.btnVerify:
               //match with generated OTP with entered OTP
               String enteredOTP = editOtp.getText().toString().trim();
               if (editOtp != null) {
                   if (enteredOTP.equals(otpFromActivity)) {
                       Toast.makeText(getBaseContext(), "OTP Verification success", Toast.LENGTH_SHORT).show();
                   } else {
                       //enter OTP verification failed
                       Toast.makeText(getBaseContext(), "OTP verfiifcation failed!", Toast.LENGTH_SHORT).show();
                   }
               } else {
                   Toast.makeText(getBaseContext(), "Enter Your OTP first", Toast.LENGTH_SHORT).show();
               }
               break;
       }
   }
}
