Android Question Verify the app download from play store

[QtechLab]

Hello programmers!

I found this java code on stackoverflow, it seems that with this function you can check if your app has been downloaded regulary from the play store or not.

boolean verifyInstallerId(Context context) {
    // A list with valid installers package name
    List<String> validInstallers = new ArrayList<>(Arrays.asList("com.android.vending", "com.google.android.feedback"));

    // The package name of the app that has installed your app
    final String installer = context.getPackageManager().getInstallerPackageName(context.getPackageName());

    // true if your app has been downloaded from Play Store
    return installer != null && validInstallers.contains(installer);
}

Has B4A a similar function?
If not how can we implement this java code in our B4A apps? (something like the "NativeObject" for B4I).

---------------- EDIT ----------------
Implemented a solution with Java inline code:

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("Main")
   
    NativeObject.InitializeContext
    DownloadRegular = NativeObject.RunMethod("verifyInstallerId", Array(Reflector.GetContext))
    If DownloadRegular Then
        PanelOutput.Color = Colors.Green
        ToastMessageShow("App security ok", False)
    Else
        PanelOutput.Color = Colors.Red
        Msgbox("App security check failed", "Error")
    End If
   
End Sub


#IF JAVA
public boolean verifyInstallerId(android.content.Context context) {
    // A list with valid installers package name
    java.util.List<String> validInstallers = new java.util.ArrayList<String>(java.util.Arrays.asList("com.android.vending", "com.google.android.feedback"));

    // The package name of the app that has installed your app
    final String installer = context.getPackageManager().getInstallerPackageName(context.getPackageName());

    // true if your app has been downloaded from Play Store
    return installer != null && validInstallers.contains(installer);
}
#End If

Thanks in advance
Best Regards
