After added the singleInstance mode. all of A,B,C are singleInstance, not Hackbod said the application limited only run one activity.
But the question is: singleInstance and singleTask mode will not auto return the last activity page. This means if I launch A from home by MAIN/LAUNCHER and A startActivity B, then return to Home, click my application icon again, it will only call A's onNewIntent->onResume, it will not return to B automatic. How can I get the History stack, and return to B? Best wishes, OCSDN 2009/1/13 Dianne Hackborn <[email protected]> > Please don't use singleInstance, use singleTask instead.
