Android Studio: android.support.v7.widget.RecyclerView Error
<p>I am currently having this error. I am using API 21 and I know some folks here suggested to upgrade it to API 22 base on previous questions but the tutorial(Slidenerd of Youtube) I am following is using API 21 and did not encountered any errors like this. Weird thing also because my RecyclerView in emulator is just working fine as expected in his tutorial and I don't why this error keeps popping up. Thanks !</p>
