I've experienced similar crash, with custom selection action mode callback set (Textview's setCustomSelectionActionModeCallback method)

Exception java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.Editor$SelectionModifierCursorController.hide()' on a null object reference

Similar problem on the SelectionModifierCursorController, but primarily on the isDragAcceleratorActive()

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.widget.Editor$SelectionModifierCursorController.isDragAcceleratorActive()' on a null object reference

Any Solution for this Error

Same here with isDragAcceleratorActive().

Don't even know which view is causing this.

This isn't the best solution in the world, but it will fix the crash. Samsung devices won't be able to copy/paste or highlight text in the EditText anymore. (Because both are using long press gestures) . Basically just override the OnLongClickListener if the device is a Samsung.

if (android.os.Build.MANUFACTURER == "samsung") {
    myEditText.setOnLongClickListener(new OnLongClickListener() {
      public boolean onLongClick(View arg0) {
        return true;    // return true to say it was handled
      }
    });
}

(I haven't tested this code on native android, but similar code in Xamarin Android project works)

Ignore my last semi-solution, it doesn't block the copy paste menu from appearing completely.  This will:

1. Check if Android.Build.Model.toLowerCase().startsWith('sm-g930').  Do not match the whole string, the last letter is a minor version identifier.  I stored this boolean in shouldBlockCopyPaste variable which comes up later.

2. If it matches you want to block the copy paste menu from showing.  This is how you ACTUALLY DO IT!!!

2a. set longclickable to false in XML or code. And/or override the LongClick method and dont do anything in it.

2b. Override these 2 functions, you'll notice my shouldBlockCopyPaste boolean, this is so other devices dont get blocked.

       @Override
       public ActionMode StartActionMode (ActionMode.Callback callback){
          if (shouldBlockCopyPaste) {
            return null;
          } else {
            return super.StartActionMode(callback);
          }
        }

       @Override
       public ActionMode StartActionMode (ActionMode.Callback callback, int type){
          if (shouldBlockCopyPaste) {
            return null;
          } else {
            return super.StartActionMode(callback, type);
          }
        }

Note devices can paste using the s-pen, no long press involved

Hello, I have the same issue too. Here you are the details:

Steps to reproduce
It happens when you long press on EditText to show the options menu. Instead, the app crashes. I faced this issue with Samsung Galaxy A5 device. I tried the above solutions but they didn't work.

Frequency
100% of the time

Android bug report:
I will try to attach it.

Kindly advise.

We are closing this issue as we don't have enough actionable information. If you are still facing this problem on latest android version, please let us know by raising a new issue along with the relevant information.

Isn't this a Google issue tracker? All the reports involve Samsung devices. I think this issue should be moved into Samsung's forums.
