i have the same problem how do I solve it ? which compile version is supported?

[insacc]

Adding
if (mViewDragHelper == null) { mViewDragHelper = ViewDragHelper.create(parent, mDragCallback); }

before to the call on the onTouchEvent() would be the workaround for now.

mViewDragHelper.processTouchEvent( event );

Hi @mrmosi13,

I'm sorry but I really don't understand what are you talking about. Can you give me more details please?
A list of things, let me know if this can help you:

1. I thought I had uploaded last merge code in bintray, am I wrong?
2. Do you import the library using gradle? Instruction about how to do it are in readme file or main page of this project.
3. this issue was about an error compiling after switch sdk version, I mean the library was working fine in previous sdk versions but when you upgraded it, it was crashing, do you have same problem?

@mamomia it should be fixed with the latest version, are you using the latest one?
