Problem with ShareActionProvider

I'm trying to make a share button via ShareActionProvider . But when the activity starts, it gives an error. I tried on Android 4.1 and Android 6.0

 java.lang.UnsupportedOperationException: This is not supported, use MenuItemCompat.getActionProvider() at android.support.v7.view.menu.MenuItemImpl.getActionProvider(MenuItemImpl.java:648) at ru.sergey.test.AboutActivity.onCreateOptionsMenu(AboutActivity.java:26) at android.app.Activity.onCreatePanelMenu(Activity.java:2476) at android.support.v4.app.FragmentActivity.onCreatePanelMenu(FragmentActivity.java:362) at android.support.v7.view.WindowCallbackWrapper.onCreatePanelMenu(WindowCallbackWrapper.java:92) at android.support.v7.app.AppCompatDelegateImplBase$AppCompatWindowCallbackBase.onCreatePanelMenu(AppCompatDelegateImplBase.java:331) at android.support.v7.app.AppCompatDelegateImplV9.preparePanel(AppCompatDelegateImplV9.java:1357) at android.support.v7.app.AppCompatDelegateImplV9.doInvalidatePanelMenu(AppCompatDelegateImplV9.java:1637) at android.support.v7.app.AppCompatDelegateImplV9$1.run(AppCompatDelegateImplV9.java:132) at android.os.Handler.handleCallback(Handler.java:615) at android.os.Handler.dispatchMessage(Handler.java:92) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4745) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) at dalvik.system.NativeStart.main(Native Method) 

Here is my code

 import android.content.Intent; import android.support.v4.view.MenuItemCompat; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.support.v7.widget.ShareActionProvider; import android.view.Menu; import android.view.MenuItem; import android.widget.Toast; public class AboutActivity extends AppCompatActivity { private ShareActionProvider mShareActionProvider; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_about); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu_main, menu); MenuItem shareItem = menu.findItem(R.id.action_share); mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(shareItem); return true; } public void doShare() { Intent intent = new Intent(Intent.ACTION_SEND); intent.setType("text/plain"); intent.putExtra(Intent.EXTRA_TEXT, "Текст"); mShareActionProvider.setShareIntent(intent); } @Override public boolean onOptionsItemSelected(MenuItem item) { int id = item.getItemId(); if (id == R.id.action_share) { doShare(); } return super.onOptionsItemSelected(item); } }
