防止在TextView中执行剪切操作时应用崩溃

Question

I put text-selectable TextView in Android layout with setTextIsSelectable(true) and the text is set by Html.fromHtml(sometexts) .
It works good to allow user to copy text. My JellyBean device gives small baloons with cut/copy/paste buttons on top of the selected text.

But when user accidently click cut icon left side of the copy menu, it crashes.

The log is given as below but there is no point to handle this exception in my application.
How to prevent app crash?

I'm not sure and I can't test it right now but maybe try to put that in your TextView xml :

android:bufferType="spannable"

If it's still not working you can implement yourself your action for the selectable event. Look at the answer of this question here : Android- How can I show text selection on textview?
