Can i use a jks as keystore for googleplay

I have some apps (cordova) on google play and I have used .keystore file So last week I started using Sony theme creator to build some themes for Sony xperia. But the software uses a jks key to release the theme.

So my question is: does Google play support a mykey.jks or just mykey.keystore file?

I'll use two keys for upload the apps.

yes, Google play support the .jks file for detail link
