Fixing NoClassDefFoundError when using older APIs

When using support library > 26.0.0 and android API < 23 if we try to create android.support.design.widget.TextInputLayout and call its addView method NoClassDefFoundError is thrown (for android.view.ViewStructure as it is not present in older APIs when trying to find the corresponding java method of a javascript method). This happens as in the method resolver we are trying to get the list of all class methods, but some of the methods accept android.view.ViewStructure parameter and this class is not present in older android APIs. As a result the getDeclaredMethods throws NoClassDefFoundError and the application crashes.

So catch for such error is added to the method getting all the method definitions and we are trying to get the exact method by name when needed.
To reproduce this you can set the following method as a StackLayout loaded event handler:

load(args) {
    console.log("loaded");
    const context = args.object.android.getContext();
    const androidView = args.object.android;
    const til = new android.support.design.widget.TextInputLayout(context);
    const editText = new android.widget.EditText(context);
    const relativeLayout = new android.widget.RelativeLayout(context);
    const relativeLayoutParams = new android.widget.RelativeLayout.LayoutParams(android.widget.RelativeLayout.LayoutParams.MATCH_PARENT, android.widget.RelativeLayout.LayoutParams.MATCH_PARENT);
    relativeLayout.setLayoutParams(relativeLayoutParams);
    editText.setHint("TEST");

    console.log("this will crash on android api <23 and support 27.1.0+");
    til.addView(editText);

    androidView.addView(til);
}

then set the supportVersion in the App_Resources/Android/app.gradle file to a version > 26.0.0:

ext {
    supportVersion = "27.1.0"
}

and run the application on a device with API level < 23.
Here's a playground application with the code from above, so downloading it and setting the supportVersion should also reproduce the issue.
