installation - Android - catch the "Cancel" event when installing an .apk programmatically -

this situation

after downloaded apk file, use following code start installation, works well.

@override public void onreceive(context context, intent intent) {      string action = intent.getaction();      if (action.equals(broadcastactionconstants.download_finished)) {         // download finished         final file file = (file) intent.getextras()                 .getserializable(downloadservice.download_file);          intent install = new intent(intent.action_view);         string pathstring = file.getabsolutepath();         install.setdataandtype(                 uri.fromfile(new file(pathstring)), "application/vnd.android.package-archive");         install.addflags(intent.flag_activity_new_task);         context.startactivity(install);     } } 

now want catch "cancel" event when installation page prompt up. plz help.

you can add receiver listen installed package

<receiver android:name=".apkinstalledreceiver" android:exported="true">     <intent-filter>         <action android:name="android.intent.action.package_added" />         <data android:scheme="package" />     </intent-filter> </receiver> 

so, if user cancels installation won't receive it.
