Fixing Google Maps Zoom Animation Issue

Hey there! Let's get your Google Maps zoom effect sorted out.

First, the problem with your current code:

mMap.animateCamera(CameraUpdateFactory.zoomTo(-1.0f), 1, null);

Google Maps doesn't accept negative values for zoom levels—this is why your map isn't displaying as expected. The valid zoom range for Google Maps typically spans from 2 (global overview) up to 21 (street-level detail) (some regions might go up to 22 for ultra-detailed views).

How to get the right zoom level for your target effect:

Start by manually adjusting the map to match the exact zoom state you want in your target image.
Once you've got it perfect, run this line of code (you can log it or print it out) to get the current zoom value:
```
float targetZoom = mMap.getCameraPosition().zoom;
```
Then update your animation code with this valid zoom value, and also adjust the duration from 1 (which is way too fast to see any animation) to a more reasonable number like 1000 (1 second) or 2000 (2 seconds):
```
mMap.animateCamera(CameraUpdateFactory.zoomTo(targetZoom), 1000, null);
```
