<uses-permission android:name= "Android.permission.SYSTEM_ALERT_WINDOW"/>

2. Concrete implementation

Package Com.pandans.hnairexam;import Com.pandans.sunshine.provider.sunshinedb.bookt;import Android.app.application;import Android.content.context;import Android.graphics.pixelformat;import Android.util.displaymetrics;import Android.view.gravity;import Android.view.windowmanager;import Android.view.windowmanager.layoutparams;public class Examapplication extends application {private Windowmanager.layoutparams windowparams = null;public windowmanager.layoutparams getWindowParams () {if (WindowParams = = null) {Createwindowparams ();} return windowparams;} Private Windowmanager.layoutparams Createwindowparams () {windowparams = new windowmanager.layoutparams (); Windowparams.type = Windowmanager.layoutparams.type_phone;windowparams.flags = WindowManager.LayoutParams.FLAG_NOT _focusable| windowmanager.layoutparams.flag_not_touch_modal| Windowmanager.layoutparams.flag_watch_outside_touch;windowparams.format = pixelformat.translucent;/* * Note that The value of flag can be: the effect of the Flags property below is the same as "lock".
