This is the main class of the Google Maps SDK for Android and is the entry point for all methods
related to the map. You cannot instantiate a GoogleMap
object directly, rather, you must
obtain one from the getMapAsync()
method on a MapFragment
or MapView
that
you have added to your application.
Note: Similar to a View
object, a GoogleMap
can only be read
and modified from the Android UI thread. Calling GoogleMap
methods from another thread
will result in an exception.
You can adjust the viewpoint of a map by changing the position of the camera (as opposed to moving the map). You can use the map's camera to set parameters such as location, zoom level, tilt angle, and bearing. For more information, see Camera and View.

animate the camera in its cancellation method. If a callback isn't required, leave it as
null . |
public void clear ()
Removes all markers, polylines, polygons, overlays, etc from the map.
public CameraPosition getCameraPosition ()

, MAP_TYPE_TERRAIN
for possible values.
Returns
- The map type.
public float getMaxZoomLevel ()
Returns the maximum zoom level for the current camera position. This takes into account what map type is currently being used, e.g., satellite or terrain may have a lower max zoom level than the base map tiles.
For more information about changing the camera's zoom level, see Camera and View.

Returns a Projection
object that you can use to convert between screen coordinates and
latitude/longitude coordinates.
The Projection
returned is a snapshot of the current projection, and will not
automatically update when the camera moves. As this operation is expensive, you should get the
projection only once per screen. Google Maps uses the Mercator projection to create its maps
from geographic data and convert points on the map into geographic coordinates.

CameraUpdateFactory
for a set of updates.
Parameters
update | The change that should be applied to the camera. |
---|
public void resetMinMaxZoomPreference ()
Removes any previously specified upper and lower zoom bounds.
public void setBuildingsEnabled (boolean enabled)
Turns the 3D buildings layer on or off.
Parameters
enabled | true to enable the 3D buildings layer; false to disable 3D
buildings.
|
---|
public void setContentDescription (String description)
Sets a contentDescription for the map.
This is used to provide a spoken description of the map in accessibility mode. The default value is "Google Map"
Parameters
description | a string to use as a description. |
---|
public boolean setIndoorEnabled (boolean enabled)
Sets whether indoor maps should be enabled. Currently, indoor maps can only be shown on one map
at a time and by default, this is the first map added to your application. To enable indoor
maps on another map, you must first disable indoor maps on the original map. If you try to
enable indoor maps when it is enabled on another map, nothing will happen and this will return
false
. When Indoor is not enabled for a map, all methods related to indoor will return
null
, or false
.
Parameters
enabled | true to try to enable indoor maps; false to disable indoor maps. |
---|
Returns
- whether it was possible to enable indoor maps.
public void setInfoWindowAdapter (GoogleMap.InfoWindowAdapter adapter)
Sets a custom renderer for the contents of info windows.
Like the map's event listeners, this state is not serialized with the map. If the map gets re-created (e.g., due to a configuration change), you must ensure that you call this method again in order to preserve the customization.
Parameters
adapter | The adapter to use for info window contents, or null to use the default
content rendering in info windows.
|
---|
public void setLatLngBoundsForCameraTarget (LatLngBounds bounds)
Specifies a LatLngBounds to constrain the camera target, so that when users scroll and pan the map, the camera target does not move outside these bounds.
Set to null to clear the bounding box completely. The new bounds replaces any previously specified bounding box.
When the LatLngBounds changes, the SDK adjusts all later camera updates to respect those bounds if possible. Note that there are technical considerations that may prevent the SDK from keeping the camera target strictly within the bounds. For example, floating point precision rounding errors or a very low zoom level.
Parameters
bounds | The bounds to constrain the camera target within. |
---|
public void setLocationSource (LocationSource source)
Replaces the location source of the my-location layer.
Parameters
source | A location source to use in the my-location layer. Set to null to use the
default location source.
|
---|
public boolean setMapStyle (MapStyleOptions style)
Sets the styling of the base map.
Using the style options, you can apply custom styles to features and elements on the map.
See MapStyleOptions
for style definition details.
Set to null to clear any previous custom styling.
Parameters
style |
---|
Returns
true
if the style was successfully parsed;false
if problems were detected with theMapStyleOptions
, including, e.g. unparsable styling JSON, unrecognized feature type, unrecognized element type, or invalid styler keys. If the return value isfalse
, the current style is left unchanged.
public void setMapType (int type)
Sets the type of map tiles that should be displayed. The allowable values are:
MAP_TYPE_NORMAL
: Basic map.MAP_TYPE_SATELLITE
: Satellite imagery.MAP_TYPE_HYBRID
: Satellite imagery with roads and labels.MAP_TYPE_TERRAIN
: Topographic data.MAP_TYPE_NONE
: No base map tiles.
Parameters
type | The type of map to display. |
---|
public void setMaxZoomPreference (float maxZoomPreference)
Sets a preferred upper bound for the camera zoom.
When the maximum zoom changes, the SDK adjusts all later camera updates to respect that maximum if possible. Note that there are technical considerations that may prevent the SDK from allowing users to zoom too deep into the map. For example, satellite or terrain may have a lower maximum zoom than the base map tiles.
The SDK resolves any conflicts in the minimum and maximum values. If you set the minimum zoom to a higher zoom level than the current maximum, then the SDK uses the new minimum value for both minimum and maximum. If you set the maximum zoom to a lower zoom level than the minimum, the SDK uses the new maximum value for both minimum and maximum. For example: Assume the current minimum zoom is 8 and the maximum is 14. Then you set the maximum zoom to 6. The SDK uses a minimum zoom of 6 and a maximum zoom of 6.
Parameters
maxZoomPreference | The preferred upper bound. |
---|
public void setMinZoomPreference (float minZoomPreference)
Sets a preferred lower bound for the camera zoom.
When the minimum zoom changes, the SDK adjusts all later camera updates to respect that minimum if possible. Note that there are technical considerations that may prevent the SDK from allowing users to zoom too low.
The SDK resolves any conflicts in the minimum and maximum values. If you set the minimum zoom to a higher zoom level than the current maximum, then the SDK uses the new minimum value for both minimum and maximum. If you set the maximum zoom to a lower zoom level than the minimum, the SDK uses the new maximum value for both minimum and maximum. For example: Assume the current minimum zoom is 8 and the maximum is 14. Then you set the minimum zoom to 16. The SDK uses a minimum zoom of 16 and a maximum zoom of 16.
Parameters
minZoomPreference | The preferred lower bound. |
---|
public void setMyLocationEnabled (boolean enabled)
Enables or disables the my-location layer.
While enabled and the location is available, the my-location layer continuously draws an indication of a user's current location and bearing, and displays UI controls that allow a user to interact with their location (for example, to enable or disable camera tracking of their location and bearing).
In order to use the my-location-layer feature you need to request permission for either
ACCESS_COARSE_LOCATION
or ACCESS_FINE_LOCATION
unless you have set a custom
location source.
If you have set a custom location source via setLocationSource(LocationSource)
the Google Maps SDK
for Android will not check whether the above permissions have been granted. However, you still
need to make sure that the user has granted all the permissions required for your custom
location source.
Parameters
enabled | true to enable; false to disable. |
---|
Throws
SecurityException | if location permission is not granted. |
---|

FusedLocationProviderApi provides improved location finding and power usage and is used by
the "My Location" blue dot. See the MyLocationDemoActivity in the sample applications
folder for example code, or the Location
Developer Guide.
Sets a callback that's invoked when the My Location dot changes location.
Parameters
listener | The callback that's invoked when the My Location dot changes. |
---|
public void setOnMyLocationClickListener (GoogleMap.OnMyLocationClickListener listener)
Sets a callback that's invoked when the My Location dot (which signifies the user's location) is clicked.
Parameters
listener | The callback that's invoked when the My Location dot is clicked. |
---|
public void setOnPoiClickListener (GoogleMap.OnPoiClickListener listener)
Sets a listener which will be triggered when a POI is clicked or tapped.
Pass null
to clear the listener.
Parameters
listener |

public void setPadding (int left, int top, int right, int bottom)
Sets padding on the map.
This method allows you to define a visible region on the map, to signal to the map that portions of the map around the edges may be obscured, by setting padding on each of the four edges of the map. Map functions will be adapted to the padding. For example, the zoom controls, compass, copyright notices and Google logo will be moved to fit inside the defined region, camera movements will be relative to the center of the visible region, etc.
Parameters
left | the number of pixels of padding to be added on the left of the map. |
---|---|
top | the number of pixels of padding to be added on the top of the map. |
right | the number of pixels of padding to be added on the right of the map. |
bottom | the number of pixels of padding to be added on the bottom of the map. |
public void setTrafficEnabled (boolean enabled)
Turns the traffic layer on or off.
Parameters
enabled |

public void snapshot (GoogleMap.SnapshotReadyCallback callback)
Takes a snapshot of the map.
You can use snapshots within your application when an interactive map would be difficult, or
impossible, to use. For example, images produced with the snapshot()
method can be used
to display a thumbnail of the map in your app, or a snapshot in the notification center.
Note: Images of the map must not be transmitted to your servers, or otherwise used outside of the application. If you need to send a map to another application or user, send data that allows them to reconstruct the map for the new user instead of a snapshot.
Parameters
callback | Callback method invoked when the snapshot is taken. |
---|
public void snapshot (GoogleMap.SnapshotReadyCallback callback, Bitmap bitmap)
Takes a snapshot of the map.
This method is equivalent to snapshot(SnapshotReadyCallback)
but lets you provide a
preallocated Bitmap
. If the bitmap does not match the current dimensions of the map,
another bitmap will be allocated that fits the map's dimensions.
Although in most cases the object passed by the callback method is the same as the one given in the parameter to this method, in some cases the returned object can be different (e.g., if the view's dimensions have changed by the time the snapshot is actually taken). Thus, you should only trust the content of the bitmap passed by the callback method.
Parameters
callback | Callback method invoked when the snapshot is taken. |
---|---|
bitmap | A preallocated bitmap. If null , behaves like snapshot(SnapshotReadyCallback) .

public void stopAnimation ()
Stops the camera animation if there is one in progress. When the method is called, the camera stops moving immediately and remains in that position.
