Android Question [Solved] java.lang.NullPointerException: Firebase Database component is not present.

[musaso]

Sorry for my bad English.
I use FirebaseRealtimeDatabase v2.82 DonManfred.
Since the update B4A v9.30 Beta #3 I have this error:

java.lang.NullPointerException: Firebase Database component is not present.

Any help will be well received thanks.

Google has changed the SDK.

You need to extend the ComponentDiscoveryService by adding DatabaseRegistrar.

Add this to the end of your manifest (manifesteditor)

AddApplicationText(
<service android:name="com.google.firebase.components.ComponentDiscoveryService" >
<meta-data
    android:name="com.google.firebase.components:com.google.firebase.analytics.connector.internal.AnalyticsConnectorRegistrar"
    android:value="com.google.firebase.components.ComponentRegistrar" />
<meta-data
    android:name="com.google.firebase.components:com.google.firebase.iid.Registrar"
    android:value="com.google.firebase.components.ComponentRegistrar" />
<meta-data
    android:name="com.google.firebase.components:com.google.firebase.auth.FirebaseAuthRegistrar"
    android:value="com.google.firebase.components.ComponentRegistrar" />
<meta-data
    android:name="com.google.firebase.components:com.google.firebase.database.DatabaseRegistrar"
    android:value="com.google.firebase.components.ComponentRegistrar"/>
</service>
)
