This is really a caring developer! As the purchase mechanism of Google Play is really disgusting and all purchase info sticks to the account tightly, to verify purchased apps we need to sign in to the Google account. My android walkman, Sony NWZ-F887, on the other hand, requires quick access and does not have lockscreen set up. So I do not want either login to the existing Google account or buy the app again. Now with such a good extension, I can make my own app using the verified Tasker for the walkman.: )
