android - Actitvity going to freez state -

i launching activity on running android app using adb command (first launch android app using adb command start activity).

activity starts after finish freezes previous running application.

adb command: adb shell start -n com.example.a/com.example.a.mainactivity`enter code here` 

java code:

public class mainactivity extends activity {     @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);     intent = new intent("com.ex.intentdemo.action_myown");         startactivity(i);         setcontentview(r.layout.activity_main);         finish();     } } 

try onpause(); instead of finish();,because finish(); ends activity. see android lifecycle.but still tell mainactivity must running open second activity.
