Problem:

I’ve written State Machine for my android application. It is separate class, extension of Android 4.0.3 StateMachine. And I want this SM could switch activities.
Is it possible to implement?
I mean that such thing as

startActivity(new Intent(CurrentActivity.this, NextActivity.class))

was called not from current activity but inside my state machine.
Thanks and sorry for my bad English.

My solution:

(special thanks to @Jan-Henk)

Inside my CurrentActivity call
stateMachine.sendMessage(SM.MSG_SWITCH_ACTIVITY, CurrentActivity.this);
and inside my State put next code:

@Override
public void exit()
{
    final Intent intent = new Intent(context, NextActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // necessary to avoid exceptions
    context.startActivity(intent);
}

@Override
public boolean processMessage(final Message message)
{
    boolean returnedValue;
    switch(message.what)
    {
        case MSG_SWITCH_ACTIVITY:
            //sendMessage(obtainMessage(MSG_SWITCH_ACTIVITY));
            context = (Context) message.obj; // context - it's a field of my state machine
            transitionTo(nextActivity);
            returnedValue = HANDLED;
        break;
        default:
            returnedValue = NOT_HANDLED;
        break;
    }           
    return returnedValue;
}
