Android code version you are running: 1.6 on a G1
Your development environment: eclipse 3.3.1.1
Describe the problem:

There is a period of around 5 seconds after leaving (any) activity with
the Home key, during which launching (any) other activity via (any) service
or broadcastreceiver is delayed until the end of that 5ish second period.

    Steps to reproduce:
    1. launch an activity via home screen
    2. exit activity by pressing home to return to launcher
    3. start an activity from a Service e.g. by pressing an appwidget
    which signals a service.

    Expected results:
    Activity starts immediately.

    Observed results:
    Around a five second delay.

    Additional information:

- most importantly, if the previous activity is exited via the Back key, no
delay occurs.
- this problem was not observed in 1.5, but has been reported for 1.6 and
2.0
- attached is the output of adb bugreport after the sequence (launch
Calculator, press Home, start Calendar via a Service)
- the main symptomatic log message is

11-06 10:16:14.030 W/ActivityManager(   82): Activity start request from
10024 stopped

Sample code (in a Service):

Intent intent = new Intent( Intent.ACTION_MAIN );
intent.addCategory( Intent.CATEGORY_LAUNCHER );

intent.setComponent(
        new ComponentName(
                pkg, cls
        )
);

intent.addFlags( Intent.FLAG_ACTIVITY_NEW_TASK );
intent.addFlags( Intent.FLAG_FROM_BACKGROUND);

//I've tried every conceivable combination of other
// Intent flags here

startActivity( intent );

A 5 second delay is ruinous for my application!

Thanks.
