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.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!

Shadow PackageParser.call ParsePackage PackageParser$Packageparserexception

I am trying to move my code to dynamic feature and while moving the test cases i created a test package inside dynamic feature module and moved related test classes there.
The test cases are not running and failing with below exception
java.lang.RuntimeException: android.content.pm.PackageParser$PackageParserException: Failed to parse /Users/anujjha/../build/intermediates/apk_for_local_test/debugUnitTest/packageDebugUnitTestForUnitTest/apk-for-local-test.ap_

There are all junit test cases. Any idea how to make it work.and what can i check in code or gradle.

SQLiteException not an error at net.sqlcipher.database.SQLiteDatabase.dbopen(Native Method)

I am facing an issue while running the junit test cases in android studio.
The issue is very strange as when I run the test cases for the first time in the phone it works perfectly fine, but if the app is already installed and when I run the test cases I get following error:-
net.sqlcipher.database.SQLiteException: not an error
at net.sqlcipher.database.SQLiteDatabase.dbopen(Native Method)
at net.sqlcipher.database.SQLiteDatabase.<init>(SQLiteDatabase.java:1942)
at net.sqlcipher.database.SQLiteDatabase.openDatabase(SQLiteDatabase.java:875)
at net.sqlcipher.database.SQLiteDatabase.openOrCreateDatabase(SQLiteDatabase.java:907)
at net.sqlcipher.database.SQLiteOpenHelper.getWritableDatabase(SQLiteOpenHelper.java:132)
at net.sqlcipher.database.SQLiteOpenHelper.getWritableDatabase(SQLiteOpenHelper.java:99)
All the sqlcipher dependencies are correctly configured.

The database might not be properly closed after you run your app the first time. Try using Close method from SQLiteConnection class:
db.Close()

I found the solution for this issue.
When I saw in the logs, I found that the actual issue was
Unable to copy icudt46l.zip file
It was happening because i was not calling the loadlibs of SQLiteCipher inside the test suites.
So I added the following line in setup() method of my test class
SQLiteDatabase.loadLibs(getContext(), getContext().getFilesDir());

Mocking Google Analytics v4

I'm trying to test my code that depends on Google Analytics SDK v4.
Specifically I'm trying to mock com.google.android.gms.analytics.Tracker with Mockito.
Tracker tracker = Mockito.mock(Tracker.class); yields this error.
Are there any approaches to take? The only thing I can think of is to create my own wrapper.

I believe the code snipped at fault is Tracker.class - as this will instantiate the class, which in turn throws the VerifyError. This is not an issue with your code, but is a limitation of Google Play Services. The issue has been reported in the Robolectric project and here.
I used the solution provided in the second link by SuperJugy, by inserting the following to the bottom of my Gradle build file:
tasks.withType(Test) {
test {
// set JVM arguments for the test JVM(s)
jvmArgs '-XX:-UseSplitVerifier'
}
}
To get it working in Android Studio I had to add the VM Option -noverify to my test build configuration.
I think you may be able to work-around the problem using a wrapper, so long as the wrapper code never instantiates the Tracker class. However this may not be easy (or possible?), please let me know if end up going down this path and succeed!

infinitest usage with Robotium for Android

I cant get infinitest(continuous test runner for TDD) to auto test with android junit test cases. Im using Robotium for UI testing.
Is infinitest compatible with Robotium ?
Here is the Problem page error (within eclipse Problem window) i get even though my test cases run fine when executed manually:
Description Resource Path Location Type
RuntimeException (Stub!) in ProjectTests. ProjectTests.java
line 0 Infinitest Test Failure
