@Avinashahex Can you post the code on how you are building your pin view? I think you are missing the step to add the key builder.

[Avinashahex]

Rendering issue is there when I am using pinview in xml.

[kevalpatel2106]

@Avinashahex Can you post your XML file and the java code for setting pin view. Keep in mind even if you use an XML file, you need to set PinView in your activity/fragment according to readme.

[Avinashahex]

Ok.
I have set the Pinview via java code its working fine, but I am not getting how to change color of invalid passcode indicator and finger scan. And can U confirm when the Dynamic pin integration can be implemented.
