You're joking right? Writing a file every minute in the background would surely drain the battery like crazy. A better solution, if you really want to know the first time your app is launched after a reboot is to listen for the Boot Completed broadcast message: http://developer.android.com/reference/android/content/Intent.html#ACTION_BOOT_COMPLETED Have your receiver write out a value to SharedPreferences... something like a boolean key/value pair with a key of "LaunchedSinceBoot" and a value of "false" Then when you launch your main app read that value and act accordingly. Then set the value to true so the next time you launch you skip the first-launch-since-boot steps...
