- First open Google maps when you have internet connection and put the destination where you want to go.
- Minimize your google map.
- Tha google map API saved the location, The google maps then still works for you if you don’t have internet connection on your way.
Look at the image below, I have entered the destination when data connection is on.
Now look at the images below, the data connection is off but still google maps is showing my location along with destination.
