I assume this carries on from your earlier question about delaying tasks in an onCreate()?
It is technically possible to move your intensive code into a "Service" and have it start when the phone boots up, but bear in mind that this is an unpopular method, as users will find their phones become sluggish whilst your app does all it's processing work in the background. My recommendation is to try and optimise your app a bit better. Otherwise you will get low ratings on the market and lots of refunds (if you plan to sell it). Some suggestions: - Take a look at some of the suggestions on your previous thread - Use a progress dialog when slow loading operations are occurring (it makes a BIG difference when the user can see that something is busy) - Delay some of your processing until the user does something (like clicking on a tab) - Cache some of your processed data, either in a database or a file, so you don't have as much to do the next time the app is loaded There are plenty of other things you can do, some thought and research should . Really, launching stuff in the background should be avoided as much as possible, mobile devices have very limited resources and your app will have a negative impact on the phone's responsiveness.
