Android Pop-up dialog box in broadcast receiver

Particular points to note are as follows:

1. Type of Alertdialog to be set

Windowmanager.layoutparams. Type_system_alert

2. Permission to declare the window bullet box

<user-permission android:name= "Android.premission. System_alert_window"/>

3. When you click on the Alertdialog button, if you use intent to make a page jump, FLAG_ACTIVITY_NEW_TASK you need to add a flag to intent

The key code in the receiver is as follows:

1  Public classForceofflinereceiverextendsbroadcastreceiver{2 @Override3      Public voidOnReceive (Finalcontext Context, Intent Intent) {4 5Alertdialog.builder Dialogbuilder =NewAlertdialog.builder (context);6Dialogbuilder.settitle ("Offline notification");7Dialogbuilder.setmessage ("Your account is logged in over elsewhere");8Dialogbuilder.setcancelable (false);9Dialogbuilder.setpositivebutton ("Re-login",Ten                 NewDialoginterface.onclicklistener () { One @Override A                      Public voidOnClick (Dialoginterface Dialog,intwhich) { -Activitycollector.finishall ();//Destroy All Activities -Intent intent1 =NewIntent (context, loginactivity.class); the                         //to start an activity in a broadcast recipient, you need to add the FLAG_ACTIVITY_NEW_TASK flag - intent1.addflags (Intent.  Flag_activity_new_task); - context.startactivity (intent1); -                     } +                 }); -Alertdialog Alertdialog =dialogbuilder.create (); + Alertdialog.getwindow (). SetType (Windowmanager.layoutparams.  Type_system_alert); A alertdialog.show (); at     } -}
