I have got a suggestion to restrict an Android application to be installed a limited number of times, let’s suppose three times for a given user account. I have already inserted a form at the start of the application which checks for username and password from our database, and returns whether its valid or not.
Next I have to apply a trick to prevent this application from being installed more than three times by each user. I hope it clears what I am trying to do. Any ideas what to do and how to proceed?
Have a
install_countcolumn in the user table in your database. Each time the user fills out form, check for theinstall_countvalue, if it is equal to 3, then don’t allow the application to continue, you can show a message like “max installs exceeded” and exit the app. Otherwise, increment the install_count value in the db for that user.PS: As Zoombie said, you can’t stop the user from installing the app, but you can restrict the user from running the application if installation limit exceeds.
Also you need to be aware, there are many apps which take a back up of the installed app and data that can be restored back anytime. More over, if the user changes his device more than thrice, he won’t be able to run your application. So consider the drawbacks of this limitation.
