The method really depends on your requirements: * If the amount of work isn't too great, and you just want the activity to be drawn before the processing starts, then postDelayed() is a sensible approach.
* If you have a lot of processing to do, and the execution needs to be linear (e.g. (a) must finish before (b) which must finish before (c)) , then an ASyncTask or Runnable would allow that to happen without interfering with the activity event loop. * If you have a lot of processing to do, but want to split it up into lots of asynchronous background tasks (and execution order is less of an issue), then using a message queue would be more manageable. If you're unsure which one you will need, then a postDelayed() is a simple approach to start off with. You could extract intensive work into background threads later on.
