I don't really understand this issue, it's about a malfunction of this library or about how to use it?
Anyway, the example project is a simple activity which launch the decoder and return back the result, you can modify it to implement your desired behaviour. Check how it's done there.

it's about how to use it not malfunctioning,I implemented this project and it's work great,on start of activity it scan qr code and stop preview OK, but now i want to scan again qr code without recreating activity on click of button start/stop so i am not getting idea how to do this,please show me way to do that.

on button click calling this method "mydecoderview.getCameraManager().startPreview();" just start camera preview but not actually scan qrcode so which method should i call for start scan again.

It's been a while since I released this lib, but I remember that Start/Stop decoding while camera is on, is not implemented. You can modify my code or the original project code, try to implement that and later make a pull request.
I'm closing this issue, since I think this is not an issue for the code, but a request for new functionalities.
