debug.certificate expiry in real device

[Vijesh Vijayanath]

Hi Ranchers,
I developed one android application which is having some SQL lite DB connection and created the .apk file. I installed the same to real device and started using that 3 months back.

Now i came to know that the app is signed using the debug.keystore certificate and it is having only 1 year validity

Is the application going to stop working once the 1 year complete??

What can i do at this point of time.? Is it possible to edit the debug.keystore and extend the expiry date??

AS per my knowledge, if i am creating a new keystore and and include in my app, that will end up in installing the app as a new app in the device and i will lose all the already loaded data in the database using the older app.

Please suggest .

Thanks,
