+## Issues With ViewGroups
+There are some ViewGroups (ones that utilize onInterceptTouchEvent) that throw exceptions when a PhotoView is placed within them, most notably [ViewPager](http://developer.android.com/reference/android/support/v4/view/ViewPager.html) and [DrawerLayout](https://developer.android.com/reference/android/support/v4/widget/DrawerLayout.html). This is a framework issue that has not been resolved. In order to prevent this exception (which typically occurs when you zoom out), take a look at [HackyDrawerLayout](https://github.com/chrisbanes/PhotoView/blob/master/sample/src/main/java/uk/co/senab/photoview/sample/HackyDrawerLayout.java) and you can see the solution is to simply catch the exception. Any ViewGroup which uses onInterceptTouchEvent will also need to be extended and exceptions caught. Use the [HackyDrawerLayout](https://github.com/chrisbanes/PhotoView/blob/master/sample/src/main/java/uk/co/senab/photoview/sample/HackyDrawerLayout.java) as a template of how to do so. The basic implementation is:
+```java
+public class HackyProblematicViewGroup extends ProblematicViewGroup {
+
+    public HackyProblematicViewGroup(Context context) {
+        super(context);
+    }
+
+    @Override
+    public boolean onInterceptTouchEvent(MotionEvent ev) {
+        try {
+            return super.onInterceptTouchEvent(ev);
+        } catch (IllegalArgumentException e) {
+            e.printStackTrace();
+            return false;
+        }
+    }
+}
+```
