[rasoulinejad]

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v4.widget.ViewDragHelper.processTouchEvent(android.view.MotionEvent)' on a null object reference at biz.laenger.android.vpbs.ViewPagerBottomSheetBehavior.onTouchEvent(ViewPagerBottomSheetBehavior.java:320)

same problem

Same issue here

[crino]

In biz.laenger.android.vpbs.ViewPagerBottomSheetBehavior line 320 should be if (mViewDragHelper != null) { mViewDragHelper.processTouchEvent(event); }

[javaghost]

Or one could add following code Below this Line:

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

Same to me :(

[yamzzzz]

For now, we can do the following:

 bottomSheet.post(new Runnable() {
            @Override
            public void run() {
                bottomSheetBehavior = ViewPagerBottomSheetBehavior.from(bottomSheet);
            }
        });

just ported the changes from support lib 27.1.0. please let me know if version 0.0.5 solves your issues

It works for me, thanks @laenger
