starting an activity from a background thread

[achim]

Hi Mark,

in your Advanced... book in the chapter about threads you write 'You
cannot modify any part of the UI from a background thread'.
What about starting an activity from a background thread? I don't see
any exception thrown and it seems to work fine, so there is one
occurrence where all the code gets executed but the UI of the activity
that got started from the background thread never shows up. Any
thoughts on this?
If I start an activity that way, does the OS put the activity on a
queue for the UIThread?

I have not attempted to start an activity from a background thread -- sorry.

I have an app that regularly starts activities from a background thread and everything works just fine, so maybe your UI problems are unrelated. You could test that by using another level of indirection; create a Runnable that starts the activity and schedule the Runnable on the UIThread.
