In that case you need to save a boolean flag in the application's user preferences and based on the value you read from there during application startup you want to bypass (or not) that particular activity.

Below is a StackOverflow link with a very basic example about the usage of Android's User Preferences APIs:

Even a better link from the Android dev site:

You need to make sure that after the first time your activity is shown and you navigate away from it, you remove that particular activity from the activity stack (so that it will not show when you press the back button on the device).

You can implement this from your AndroidManifest.xml file, just by adding [android:noHistory="true"] attribute in those activity XML elements for which you want to have this type of behaviour enabled.

Hope this helps.
