Hello forum friends I have a question I want to do that when the application is installed the apk is removed so that it can not be installed on more than one device, how can I accomplish this ?, Excuse my English is poor, hope you meet me
That seems to be an issue with Android apk deployment through the Play store. Software can be found that will retrieve the apk installation file, even from regular (non-rooted) devices. It is merely a short step for a user to rename the .apk as a .zip and get access to the assets stored inside. As you can imagine it will take a power-user to complete this successfully. It is one very good reason to encrypt underlying databases.
