android - Finish activity without waiting for completion -

i've been bit tormented finding out way finish activity without waiting complete. know simple "return;" statement trick in architecture can't it.

i have:

public abstract class basefragmentactivity extends fragmentactivity {      @override      protected void oncreate(bundle savedinstancestate) {           super.oncreate(savedinstancestate);           if (savedinstancestate != null) {                finish();                return;           }      } } 

and

public class mainactivity extends basefragmentactivity {      @override      protected void oncreate(bundle savedinstancestate) {           super.oncreate(savedinstancestate);           /* code still executed here when parent finish(); called */      } } 

how can prevent execution of code in mainactivity once finish() in abstract class called?

updated code:

public abstract class basefragmentactivity extends fragmentactivity {      @override      protected void oncreate(bundle savedinstancestate) {           super.oncreate(savedinstancestate);           if (savedinstancestate != null) {                finish();                return;           }      } }  public class mainactivity extends basefragmentactivity {      @override      protected void oncreate(bundle savedinstancestate) {           super.oncreate(savedinstancestate);           if (isfinishing()) {               return;           }      } } 

strange thing though, "return" seems work, fragmentmanager somehow launches fragment @ end.

try wrapping in

if(isfinishing()){      //code don't want execute if finish() called  }
