How to suspend my app?
<p>I have an app that spends a lot of time generating bitmaps for use as wallpaper. When the user has selected a bitmap and applied it, I would like to go to the main launcher screen so it can be seen "for real". </p>

<p>I could just exit the app when the selection is made, but I would like to maintain state at least for a short time so that if the user wants to go right back in to change cropping or select a different bitmap, things are as they were before. </p>

<p>Andy ideas? Is there an Intent I could use to get back to the main launcher screen? Maybe simulate the "Home" button being pressed?</p>

<p>Thanks!</p>
