Calling StartActivity () from outside of an Activity context requires the Flag_activity_new _task FLAG.

There is no limit to using the StartActivity () method in activity because activity overloads the StartActivity () method of the context. However, if you use the StartActivity () method in other places (such as widgets or service, broadcastreceiver), you will get an error:

Android.util.AndroidRuntimeException:Calling startactivity () from outside of an Activity context requires the Flag_activ Ity_new_task flag. Is this really what do you want?

At this point, you need to set a Flag_activity_new_task flag for intent:

Intent.addflags (Intent.flag_activity_new_task);

This will not be an error, you can smooth the startactivity ().
