Enumerations

DependencyStatus

DependencyStatus

An enum that indicates the current status of the dependencies on the current system, required forFirebase to run.

Properties

On Android, this means that Google Play services is disabled.

Reports whether aFirebase module initialized successfully.

Properties
FailedMissingDependency

The given library failed to initialize due to a missing dependency.

On Android, this typically means that Google Play services is not available and the library requires it. Use FirebaseApp.CheckDependencies() andFirebaseApp.FixDependenciesAsync() to resolve this issue.

Also, on Android, this value can be returned if the Java dependencies of aFirebase component are not included in the application, causing initialization to fail. This means that the application's build environment is not configured correctly. To resolve the problem, see the SDK setup documentation for the set of Java dependencies (AARs) required for the component that failed to initialize.

Success

The given library was successfully initialized.
