Android determines whether the mobile phone has a map application installed to jump to the map application

preface

Now many applications will use maps, but we certainly don't want to get a navigation god horse in our app, so the third-party map also opens up a shortcut for us to directly transmit data to the map application and let the third-party map help us do all this.

First of all, you need to determine whether a map application is installed on your mobile phone. Here is a method:
