Android Question [solved] Failed resolution of: Landroid/arch/lifecycle/ViewModelProviders

DonManfred · May 6, 2018

I am in the phase of Updating the Firebase UI Auth library with the newest Maven Artifacts and the newest Version of the Githubproject.

I updated all Artifacts, i updated the Firebase UI - Code from Github to the newest release (last updated about a month ago).
I realized that google has changed the way to add a Auth-Provider.
I needed to rewrite the wrapper to match the new Google-Rules resp. to match the new UI Library

After i came into different errors it is all done now.

But now, when i call the FirebaseUI to show the available Providerslist to select one from it crashes because of

NoClassDefFoundError: Failed resolution of: Landroid/arch/lifecycle/ViewModelProviders;

android/arch/lifecycle/ViewModelProviders is part of android.arch.lifecycle.viewmodel

I tried to get rid of them using

B4X:

#AdditionalJar: android.arch.lifecycle:viewmodel

but the error is the same

I copied the aar from the B4A SDK Managers b4a_remote Folder...
I tried to use

B4X:

#AdditionalJar: viewmodel-1.1.1.aar

But then i get a error when compiling.

No matter what i try it does not work...
If i remember correctly then i read something in the past (maybe from Erel; can´t remember) that these Lifecycle components are added at compilitime when using Android Studio.

I guess they are included in the AARs which i created with AS.

#AdditionalJar: firebase-ui-auth.aar ' Probably this one
#AdditionalJar: firebase-ui-common.aar
#AdditionalJar: firebase-ui-database.aar
#AdditionalJar: firebase-ui-firestore.aar
#AdditionalJar: firebase-ui-storage.aar

But as of now i did not find a solution to get the new UI-Auth running. I dont know why the classes are not recognized to be available.

Does anyone have an idea what this can be? Any hints are highly welcome

1. Google: ViewModelProviders

2. https://developer.android.com/reference/android/arch/lifecycle/ViewModelProviders

3. Try:

B4X:

#AdditionalJar: android.arch.lifecycle:extensions

Dooooh!
It does work!

Thank you very much. Sometime i do not see the forest about the trees.

Ok, i´m now facing a new problem. But it seems to be related to the manifest entries needed for the Update UI Bindings.

I´m a step further

the error i got was to a missing manifest entry which i neeeded to add.

AddApplicationText( <activity
android:name="com.firebase.ui.auth.KickoffActivity"
android:label=""
android:exported="false"
android:theme="@style/FirebaseUI.Transparent" />

<activity
android:name="com.firebase.ui.auth.ui.email.RecoverPasswordActivity"
android:label="@string/fui_title_recover_password_activity"
android:exported="false" />

<activity
android:name="com.firebase.ui.auth.ui.email.RegisterEmailActivity"
android:label="@string/fui_sign_in_default"
android:exported="false" />

<activity
android:name="com.firebase.ui.auth.ui.phone.PhoneVerificationActivity"
android:label="@string/fui_sign_in_with_phone_number"
android:windowSoftInputMode="stateAlwaysVisible"
android:exported="false" />

<activity
android:name="com.firebase.ui.auth.ui.accountlink.WelcomeBackIdpPrompt"
android:label="@string/fui_title_welcome_back_idp_prompt"
android:exported="false" />

<activity
android:name="com.firebase.ui.auth.ui.accountlink.WelcomeBackPasswordPrompt"
android:label="@string/fui_title_welcome_back_password_prompt"
android:exported="false" />

<activity
android:name="com.firebase.ui.auth.ui.idp.AuthMethodPickerActivity"
android:label="@string/fui_default_toolbar_title"
android:exported="false" />
<activity
android:name="com.firebase.ui.auth.ui.credentials.CredentialSaveActivity"
android:label=""
android:exported="false"
android:theme="@style/FirebaseUI.Transparent" />

)

CredentialSaveActivity was new and missing... After i added it it is working now.
