java.lang.IllegalStateException: System services not available to Activities before onCreate()

问题:

I am getting an exception :

java.lang.IllegalStateException: System services not available to Activities before onCreate() 

while reinitializing layoutInflater in onResume() like :

layoutInflater = (LayoutInflater) context                 .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

I am trying to updatethe The content of view flipper. Can anyone suggest me the corrections in this to resolve the exception.

Behold:

public class MyActivity extends Activity {      // LayoutInflater inflater = (LayoutInflater) context      //         .getSystemService(Context.LAYOUT_INFLATER_SERVICE); // NOT CORRECT     LayoutInflater inflater; // correct      @Override     protected void onCreate(Bundle saved) {         super.onCreate(saved);         inflater = (LayoutInflater) context              .getSystemService(Context.LAYOUT_INFLATER_SERVICE); // correct     } }
