Permissions

You must add the following permissions in order to use the Google Maps Android API:

• android.permission.INTERNET Used by the API to download map tiles from Google Maps servers.

• android.permission.ACCESS_NETWORK_STATE Allows the API to check the connection status in order to determine whether data can be downloaded.

The following permissions are not required to use Google Maps Android API v2, but are recommended.

• android.permission.ACCESS_COARSE_LOCATION Allows the API to use WiFi or mobile cell data (or both) to determine the device's location. The API returns the location with an accuracy approximately equivalent to a city block.

• android.permission.ACCESS_FINE_LOCATION Allows the API to determine as precise a location as possible from the available location providers, including the Global Positioning System (GPS) as well as WiFi and mobile cell data.

• android.permission.WRITE_EXTERNAL_STORAGE Allows the API to cache map tile data in the device's external storage area.

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

<uses-feature android:name="android.hardware.location.network" android:required="false" />
<uses-feature android:name="android.hardware.location.gps" android:required="false"  />

You must also explicitly declare that your app uses the android.hardware.location.network or android.hardware.location.gps hardware features if your app targets Android 5.0 (API level 21) or higher and uses the ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permission in order to receive location updates from the network or a GPS, respectively.

Note: It supports runtime permissions for Android 6 (Marshmallow). You don't need to do anything, it will ask for permissions if needed.
