Unable to cast Action Provider to Share Action Provider
I had the same problem and I have found the solution: 1) You have to use: <menu xmlns:android=”http://schemas.android.com/apk/res/android” xmlns:bwq=”http://schemas.android.com/apk/res-auto” > <item android:id=”@+id/menu_share” android:title=”@string/menu_share” bwq:actionProviderClass=”android.support.v7.widget.ShareActionProvider” bwq:showAsAction=”always”/> </menu> 2) and in Java import android.support.v7.widget.ShareActionProvider; and // Locate MenuItem with ShareActionProvider MenuItem item = menu.findItem(R.id.menu_share); // Fetch and store ShareActionProvider mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(item);
