onNewIntent的应用

onCreate是用来创建一个Activity也就是创建一个窗体，但一个Activty处于任务栈的顶端，若再次调用startActivity去创建它，则不会再次创建。若你想利用已有的Acivity去处理别的Intent时，你就可以利用onNewIntent来处理。在onNewIntent里面就会获得新的Intent.

@Override
 protected void onNewIntent(Intent intent) {
  // TODO Auto-generated method stub
  super.onNewIntent(intent);
  
 }

开发手册上的说明：

protected void onNewIntent (Intent intent)

Since: API Level 1

This is called for activities that set launchMode to "singleTop" in their package, or if a client used the FLAG_ACTIVITY_SINGLE_TOP flag when calling startActivity(Intent). In either case, when the activity is re-launched while at the top of the activity stack instead of a new instance of the activity being started, onNewIntent() will be called on the existing instance with the Intent that was used to re-launch it.

An activity will always be paused before receiving a new intent, so you can count on onResume() being called after this method.

Note that getIntent() still returns the original Intent. You can use setIntent(Intent) to update it to this new Intent.

Parameters

intent	The new intent that was started for the activity.
