Is there any way to receive the installation date of an android app? Or any other suggestions on how to accomplish a 30 day free trial version? Thanks alot.

A:
Just save the time when the application was first run. Then compare the time each time the program starts.
Another more secure way (the above tactic could be beaten by a simple reinstall) is to have a server of yours authenticate the imei number of the device the first time it's run and then continue the above method.
