Base class for Google API entry points. API clients based on this class manage the
connection between your app and Google Play services (as opposed to GoogleApiClient
-based
calls).
GoogleApi-based instances enqueue calls until a connection is made to Google Play services, and then execute them in order. The instances are:
- "Cheap" to create
- Thread-safe
- Automatically deduplicated
- Automatically timed-out and reconnected when necessary
GoogleApi
abstracts the connection to Play services, so callers do not need
to implement
GoogleApiClient.ConnectionCallbacks
.
If the user needs to install or update Google Play services, GoogleApi
will
prompt the user to do so and enqueue API calls until the issue is resolved. If
GoogleApi
was initialized with an Activity
it will create a
foreground prompt, otherwise it will display a system notification. If the user cancels the
resolution or some other issue arises, pending API calls will be fail with an ApiException
and status code CommonStatusCodes.API_NOT_CONNECTED
.
If
GoogleApiAvailability.isGooglePlayServicesAvailable(Context)
returns
true
, GoogleApi
instances will not show any UI to resolve
connection failures.

Protected Methods
protected String getApiFallbackAttributionTag (Context context)
This method is only invoked on versions below Android R, where no attribution tag is available. If APIs have some other type of client identifier they wish to use, they may implement this method in order to provide their own fallback which will be used in place of the attribution tag (and thus passed through client/module implementations as the attribution tag).
This method is invoked from the constructor, and should be careful not to reference uninitialized members or allow references to escape.
