The entry point of Firebase SDKs. It holds common configuration and state for Firebase APIs. Most applications don't need to directly interact with FirebaseApp.
For a vast majority of apps,
will handle the initialization of Firebase for the default project that it's configured to
work with, via the data contained in the app's
google-services.json file. This
ContentProvider is merged into the app's manifest by default when building with
Gradle, and it runs automatically at app launch. No additional lines of code are
needed in this case.
In the event that an app requires access to another Firebase project in addition
to the default project,
initializeApp(Context, FirebaseOptions, String) must be used to create that
relationship programmatically. The name parameter must be unique. To connect to the resources
exposed by that project, use the
passing it the same name used with
initializeApp. This object must be passed to
the static accessor of the feature that provides the resource. For example,
getInstance(FirebaseApp) is used to access the storage bucket provided by the
additional project, whereas
is used to access the default project.
FirebaseApp initialization must occur only in the main process of the
app. Use of Firebase in processes other than the main process is not supported and will
likely cause problems related to resource contention.
Public Method Summary
Returns the unique name of this app.
If set to true it indicates that Firebase should close database connections automatically when the app is in the background.
