[Bug] System.TypeLoadException: Parent class vtable failed to initialize, due to: VTable setup of type AndroidX.SwipeRefreshLayout.Widget.SwipeRefreshLayout #14424

2022-02-17T21:28:00.008-08:00

Ended up having to install

Xamarin.AndroidX.AppCompat.AppCompatResources (version 1.3.0)

and downgrading

Xamarin.AndroidX.Core from version 1.6.0 to 1.5.0

it began after updating to Xamarin Forms 5.0.0.2083 which required AndroidX.Core

Not sure if it'll help with your problem exactly but those steps fixed it .

downgrading Xamarin.AndroidX.Core from version 1.6.0 to 1.5.0 resolved issue.

Do you think this is fixed with the new AndroidX.Core 1.6.0.1 ?

Updating to 1.6.0.1 didn't work for us as well but we have 2 workarounds for this.

Skip linking for Xamarin.AndroidX.Core
Put this <AndroidLinkSkip>Xamarin.AndroidX.Core</AndroidLinkSkip> in *.Droid.csproj
or

Alternatively
Install "Xamarin.Google.Android.Material" and "Xamarin.AndroidX.SwipeRefreshLayout" directly in your *.Droid project

We picked the first solution, mainly because this is a workaround and using "Skip linking assemblies" will raise questions if we forget about it.
Where adding 2 packages as a workaround probably will get unnoticed and they will stay there forever.
At some point this issue will be fixed in the Xamarin.AndroidX.Core package and this workaround should be removed.

Second update, even installing both nugets and adding <AndroidLinkSkip>Xamarin.AndroidX.Core</AndroidLinkSkip>, the exception still comes up.
However now with this message.

Parent class vtable failed to initialize, due to: VTable setup of type AndroidX.CoordinatorLayout.Widget.CoordinatorLayout failed assembly:Xamarin.AndroidX.CoordinatorLayout.dll type:CoordinatorLayout member:(null)

So same error, for another control. So I also installed Xamarin.AndroidX.CoordinatorLayout. Now it seems to start.

update XF to 5.0.0.2012, Xamarin.AndroidX.SwipeRefreshLayout to 1.1.0.5 and Xamarin.AndroidX.RecyclerView to 1.2.1.3, problem solved

just give a check meta-data tag is out of activity tag

if it is like this

<manifest>
    <application>
        <activity>
            <meta-data> 
                android:name="com.google.android.gms.ads.APPLICATION_ID" 
                android:value="ca-app-pub-4347201915048498~6120388314"/>
        </activity>
    </application>
</manifest>

this should be changed to this

<manifest>
    <application>
        <activity>
        </activity>
        <meta-data 
            android:name="com.google.android.gms.ads.APPLICATION_ID" 
            android:value="ca-app-pub-4347201915048498~6120388314"/>
    </application>
</manifest>

OR


  
  
  
  
 
  
  
  
  
  Only add this code to the manifest on your app and thats it
<meta-data
            android:name="com.google.android.gms.ads.AD_MANAGER_APP"
            android:value="true"/>


                                         OR
Note:- Make sure you don't have your meta-data tag inside activity...been there, done that.


<application>
   ...
   ...
   < meta-data 
        android:name="com.google.android.gms.ads.APPLICATION_ID" 
        android:value="ca-app-pub-################~##########"/> 
</application>
The solution is to put the meta data lines at Last (means below all other meta-data present in your android manifest file but just before closing application tag).

Don't get confused with APPLICATION_ID. You should not replace it with your application ID for ex. com.example.myapp. Just keep it as it is.
<application>
...
      <meta-data 
           android:name="com.google.android.gms.ads.APPLICATION_ID" 
           android:value="ca-app-pub-################~##########"/>
...
</application>
