Let's say you have a TabActivity with activities A1, A2, A3, and A4. When you click on the different tabs, no matter how many times you navigate between them, when you press the back key you leave the entire tab group, instead of navigating to a previous tab. My problem is, I am not using an actual TabActivity.
Does anyone know how to specify to Android that I'd like to mimic that behavior with a group of activities? The classic solution (that I know of) would to simply finish() the activity as you navigate away from it. That clears the stack, so that when you went from A1 and then to A2, and pressed back, you don't go back to A1. The problem with using finish() is that I don't want the activity removed from memory. These activities load data from the network, so unless the data was cached, it would need to be reloaded on every navigation which would not be a great user experience. I was looking at the flags which you can specify how to change this behavior: http://developer.android.com/guide/topics/fundamentals.html#acttask I tried using these: intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); But no matter what, when I go from A1 to A2 and press back, I always get back to A1. Can anyone help in trying to clear the navigation stack without using finish()? Thanks! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
