I want to remove the copy protection of one of my applications at the market. Is necessary to upload a new apk for take effect or is just necessary 开发者_开发技巧to uncheck the copy protection checkbox. I dont wanna upload an update if its not necessary

Copy protection is obsolete and not so well documentef. Don't try to save a release if you're not sure.

Just ulpload something on the market that is exactly what you eant your users to have.
