The APP often uses geographic location authorization. The following describes the encapsulation of gps and suspension window on Android
Only part of the code and the creation of interaction classes are shown here Portal

There's a problem here. Because Android manufacturers are different, when users refuse to authorize geographical location, they can't accurately transfer to the corresponding permission management of the app, so they just jump to the application information page

As for the use of alert dialog, Android's pop-up box, don't forget to use show() to display it.
