       //Example Message Format

        <#>Your AndroidHunt OTP is: 8686. ynfd/rIwy/+

        ynfd/rIwy/+  is the hash code of your Application

       //There are Two  Ways To Genearate Hash Code One Is By Using Command Line
        keytool -exportcert -alias YOUR_KEYSTORE_ALIAS -keystore YOUR_KEYSTORE_FILE | xxd -p | tr -d "[:space:]" | echo -n com.example.myapp `cat` | sha256sum | tr -d "[:space:]-" | xxd -r -p | base64 | cut -c1-11

      //Other Way  By Doing Programatically Inside The Application.
      //Here You get Hash code by Using With Our Library
      String hashCode = AutoDetectOTP.getHashCode(this);
      // above string like this "ynfd/rIwy/+"
