To mitigate the vulnerability associated with insecure package context creation using createPackageContext with CONTEXT_INCLUDE_CODE and CONTEXT_IGNORE_SECURITY flags, developers should: 

1- Avoid using createPackageContext by baking any necessary components into the app itself rather than using separate apk files.

2- if using createPackageContext is necessary, avoid using the flags `CONTEXT_INCLUDE_CODE` and `CONTEXT_IGNORE_SECURITY`, instead use `CONTEXT_RESTRICTED` which may disable specific features but makes the application more robust against third party application attacks.

3- When checking if the package is in the list of installed packages, avoid loose comparisons like `startsWith` or `endsWith`, instead try matching the package name exactly

# Code Examples:

### Java

```java
import android.content.Context;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import java.lang.reflect.Method;
import java.util.List;

public final class InsecurePackageContext {

    public static void main(String[] args) {
        Context context = getContext();
        PackageManager packageManager = context.getPackageManager();

        List<PackageInfo> installedPackages = packageManager.getInstalledPackages(PackageManager.GET_META_DATA);

        for (PackageInfo info : installedPackages) {
            String packageName = info.packageName;

            if (packageName.equals("co.ostorlab.plugins.camera")) {
                try {
                    Context packageContext = context.createPackageContext(packageName,
                            Context.CONTEXT_RESTRICTED);

                    Class<?> loaderClass = packageContext.getClassLoader().loadClass("co.ostorlab.plugins.camera.Main");
                    Method updateMethod = loaderClass.getMethod("Update", Context.class);
                    updateMethod.invoke(null, context);

                } catch (Exception e) {
                    throw new RuntimeException(e);
                }
            }
        }
    }
}

```
