Code-signed apk fails

I'm fairly sure that's the reason the file dialog didn't enable the .jks file, but the file 
still works. I used Google's terminal command example, which creates .jks files, instead of 
LC's example which I think uses .keystore. Next time I'll change the extension just to make 
file selection easier.
