And it works as a charm.
You have a toast and you get image with link - which opens Google Maps application.
I figure it out. Go to https://developers.google.com/maps/documentation/maps-static/intro. Grab a Key with Enabled API's: https://console.cloud.google.com/home/dashboard. Add no restrictions or use only for Android SDK.
Changes to the MainActivity.java:
Create new file LocationTrack.java:
Full code here: https://www.journaldev.com/13325/android-location-api-tracking-gps
strings.xml
<string name="api_key_google_places">YOUR_API_KEY</string>app/build.gradle:
Util.java
change this:
return "https://maps.googleapis.com/maps/api/staticmap?center="+latitudeFinal+","+longitudeFinal+"&zoom=18&size=280x280&markers=color:red|"+latitudeFinal+","+longitudeFinal;to this:
return "https://maps.googleapis.com/maps/api/staticmap?center="+latitudeFinal+","+longitudeFinal+"&zoom=18&size=640x640&maptype=roadmap&key=YOUR_KEY_HERE&markers=color:red|"+latitudeFinal+","+longitudeFinal;And it works as a charm.
