NativeScript Build - Error executing Static Binding Generator: Class not found android.support.v4.view.ViewPager.OnPageChangeListener

I'm new to NativeScript and took over a project recently upgraded from NativeScript 4 to 6. Here is my environment detials:
Windows 10
Node v16.6.1
NativeScript 8.0.2
Android Studio 11 (with al
the recommended updates to date)
VS Code 1.58.2
I can create a new Native script project with "tns create" and build/run it in the simulator just fine. However, when I try to run the project the build throws the following error:
java.lang.RuntimeException: Class not found android.support.v4.view.ViewPager.OnPageChangeListener
at org.nativescript.staticbindinggenerator.Generator.getClass(Generator.java:551)
at org.nativescript.staticbindinggenerator.Generator.getInterfacesFromCache(Generator.java:534)
at org.nativescript.staticbindinggenerator.Generator.writeBinding(Generator.java:283)
at org.nativescript.staticbindinggenerator.Generator.generateBinding(Generator.java:171)

at org.nativescript.staticbindinggenerator.Generator.writeBindings(Generator.java:97)
at org.nativescript.staticbindinggenerator.Main.main(Main.java:55)
Here is the run command I'm using: "tns run android --emulator"
I have tried tons of things and searches but no luck resolving this issue.

So I had an idea and searched with a different search engine than I normally use. I did find some ideas which helped me resolved the issue.
I had previously searched in VSCode for variations on "android.support.v4.view.ViewPager.OnPageChangeListener", but only found the log file with the error. Then I learned you have to change the filter options of the find in file search otherwise the files you are looking for can be excluded from the search results. I also used Baregrep to confirm I was getting everything.
I fixed the issue by replacing all occurrences of:
android.support.v4.view.ViewPager with androidx.viewpager.widget.ViewPager
Also you may need to install widgets:npm i tns-core-modules-widgets
Since the files where I made the changes were all non-project files (many of them in the node_modules directory) there is probably something else that involves updating Node or NativeScript that may solve this as well.
If someone else figures that out, I'll be watching this thread for updates, and thanks in advance!

Could not find class 'com.badlogic.gdx.backends.android.Android GL10

I'm trying to deploy my libgdx game to Android, but I keep getting this error on my logcat "Could not find class 'com.badlogic.gdx.backends.android.Android GL10', referenced from method com.badlogic.gdx.backends.android.Android Graphics.setupGL". I'm not even using AndroidGL10 as far as I know. Anybody had that error before? How do I fix it?

It's working now. Since I'm currently using the 1.9.6 version, I had to update my gdx-backend-android.jar. I downloaded a compatible version: gdx-backend-android-1.9.6.jar. Thanks!!

PhoneGap 2.0 Upgrade Errors - JSCallback Error / Could not find class

I updated my Phonegap (Cordova) project from 1.9 to 2.0 and am receiving the following two new errors:
Web Console
JSCallback Error: Request failed. at file file://android_assets/www/js/cordova-2.0.0.js:3698
and
dalvikvm
Could not find class 'android.webkit.WebResourceResponse', referenced from method org.apache.cordova.CordovaWebViewClient.generatedWebResourceResponse
Is this a known problem? I have searched but can't find a solution that addresses these issues. I have tried creating a new blank project and I am getting the same errors. I have also ensured Eclipse and the SDK manager are up to date.
Any help would be much appreciated.
Thank you.

Not sure about the first question as I need to know what you are doing when that log appears.
Regarding the second question:

App Engine Connected Android Project - Could not find ...RequestFactorySource

I'm unable to run even the default App Engine connected Android app, since updating my SDK. I've gone as far as deleting eclipse and all of my libraries and reinstalling them with no success. I've followed Google's tutorial to the letter and verified the validation tool is in my build path. This is the error I'm getting (and yes requestfactory-client.jar is in my library).
dalvikvm(375): Could not find method com.google.web.bindery.requestfactory.vm.RequestFactorySource.create, referenced from method com.Util.getRequestFactory
dalvikvm(375): VFY: unable to resolve static method 84: Lcom/google/web/bindery/requestfactory/vm/RequestFactorySource;.create (Ljava/lang/Class;)Lcom/google/web/bindery/requestfactory/shared/RequestFactory;
I'm completely lost at this point and about to pull some hair out, please help. Thanks

In my case it's an issue with the new ADT 17 and how it handles library projects. This post is a good explanation on how to fix it:

I, too, was going crazy on this. Hope this helps.
The validation step can be important too (like you did):
