Yes, it looks like issue in Support v4 library, below is implementation equivalent to HackyViewPager for DrawerLayout. I will add the class to Sample project and close this issue after merge.

import android.content.Context;
import android.support.v4.widget.DrawerLayout;
import android.util.AttributeSet;
import android.view.MotionEvent;

public class HackyDrawerLayout extends DrawerLayout {


    public HackyDrawerLayout(Context context) {
        super(context);
    }

    public HackyDrawerLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public HackyDrawerLayout(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        try {
            return super.onInterceptTouchEvent(ev);
        } catch (Throwable t) {
            t.printStackTrace();
            return false;
        }
    }
}

use in layout like this

<your.application.package.HackyDrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:id="@+id/drawer_layout"
    android:layout_height="match_parent">
</your.application.package.HackyDrawerLayout>

I keep getting the ArrayIndexOutOfBoundsException even though I’ve implemented the fix described in smareks comment.

I can see that the my ImageView is part of the HackyDrawerLayout and that the onInterceptTouchEvent in that class is run at times, but the exception is never catched when the exception occur.

This is my onInterceptTouchEvent:

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        try {
            return super.onInterceptTouchEvent(ev);
        } catch (ArrayIndexOutOfBoundsException e) {
            e.printStackTrace();
            return false;
        }
    }

And my xml file:

<?xml version="1.0" encoding="utf-8"?>
<co.org.app.HackyDrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <ProgressBar
            android:id="@+id/progress_bar"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true" />

        <ImageView
            android:id="@+id/image_view_image_display"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

        <android.support.design.widget.CoordinatorLayout
            android:id="@+id/snackbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </RelativeLayout>

</co.org.app.HackyDrawerLayout>

Any ideas?
