my activity:

package com.progressindicator;  import android.app.activity; import android.graphics.drawable.animationdrawable; import android.os.bundle; import android.view.menu; import android.view.window; import android.view.windowmanager; import android.view.windowmanager.layoutparams; import android.widget.imageview; import android.widget.linearlayout;  public class progressindicator extends activity {     imageview loading;     animationdrawable loadanimation;     private window wind;     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         //setcontentview(r.layout.activity_progress_indicator);     //  requestwindowfeature(window.feature_no_title);     //  requestwindowfeature(windowmanager.layoutparams.flag_show_when_locked); //      wind = this.getwindow(); //      wind.addflags(layoutparams.flag_dismiss_keyguard); //      wind.addflags(layoutparams.flag_show_when_locked); //      wind.addflags(layoutparams.flag_turn_screen_on);          getwindow().addflags(                  windowmanager.layoutparams.flag_show_when_locked               );         linearlayout main = new linearlayout(this);         main.setorientation(linearlayout.vertical);         setcontentview(main);          loading = new imageview(this);         loading.setimageresource(r.drawable.loading);         loadanimation = (animationdrawable)loading.getdrawable();         main.addview(loading);     }     @override     public void onwindowfocuschanged(boolean hasfocus){      loadanimation.start();      }     @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.progress_indicator, menu);         return true;     }  } 

try adding windowmanager.layoutparams.flag_show_when_locked activity started, temporarily disable keyguard/keylock long activity on top of other windows.
