java.lang.IllegalArgumentException: pointerIndex out of range Exception - dispatchTouchEvent

Question

I have this method in my custom view which extends FrameLayout:

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    int currentItem = vp.getCurrentItem();
    if (inDragPanelZone(currentItem, ev.getX(), ev.getY()) && ev.getAction() == MotionEvent.ACTION_DOWN) {      
        if (!shouldAllowPaging()) { 
            return true; 
        }
        vp.setPagingEnabled(true);
    }
    return super.dispatchTouchEvent(ev);
}

Once in a while - I'm getting the following Exception:

I also tried using onInterceptTouchEvent() and got the same exception.

Here is an additional stacktrace:

I'm also facing the same problems sometimes. Try to dispatch copy of `ev` instead of original `MotionEvent`. In the very begginning of method add something like `MotionEvent evCopy = MotionEvent.obtain(ev)` and call `super.dispatchTouchEvent(evCopy)` instead. — Dmitry Zaytsev, May 09 '13 at 10:45
I didn't tried it yet. For me, problem disappeared when I get rid of `ScrollView` and redesigned the app for another reasons. — Dmitry Zaytsev, May 09 '13 at 10:51
it's `return super.dispatchTouchEvent(ev);` in the code snippet in the question. — Daniel L., May 13 '13 at 08:46
Does this still happen in the lastest versions of support v4? — Kyle Jahnke, Dec 01 '15 at 21:39

There is a bug in 2.1 (Eclair) where the pointer index isn't checked and is sometimes -1. You can create a custom view that extends ViewPager, override onTouchEvent and wrap the call to super.onTouchEvent in a try/catch. Whilst not a very pretty fix, I remember that it has no side effects (like missed touch events).

I saw this bug, and I've used the workaround you suggested before, but I'm trying to find a way to handle it properly.. – Daniel L. May 13 '13 at 10:49

There was an update to the support library recently which may have fixed this error (as in, they fixed ViewPager, not the causing bug in 2.1). Haven't checked it out. – FunkTheMonk Oct 14 '13 at 14:11

@FunkTheMonk nope the bug is still there :( – martyglaubitz Sep 11 '14 at 11:25
I've still got this bug, but the suggested fix works – user1743524 Oct 28 '14 at 21:12
Did anyone see the same behaviour in android 4.4.4? I see a stacktrace where `at android.support.v4.view.MotionEventCompatEclair.c(MotionEventCompatEclair.java:32)` is in front of `at android.view.MotionEvent.getX(MotionEvent.java:2227)` and it results in the above mentioned exception... – prom85 Jun 16 '15 at 07:15

Adding to the above answer Also you can try Overriding onInterceptTouchEvent method and surround super.onInterceptTouchEvent(ev) with try and catch worked for me in a ViewPager

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

What should i do if it got crash inside super.onInterceptTouchEvent(ev)? – Steve Luck Apr 23 '16 at 04:06

I had the same problem and I created a custom ViewPager to catch the exception. Here is the solution in kotlin:

class CustomViewPager : ViewPager {

    constructor(context: Context) : super(context)

    constructor(context: Context, attrs: AttributeSet?) : super(context, attrs)

    override fun onInterceptTouchEvent(ev: MotionEvent?): Boolean =
        try {
            super.onInterceptTouchEvent(ev)
        } catch (e: IllegalArgumentException) {
            //uncomment if you really want to see these errors
            //e.printStackTrace();
            false
        }
}
