@Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.menu, menu); // Locate MenuItem with ShareActionProvider MenuItem item = menu.findItem(R.id.Share_id); // Fetch and store ShareActionProvider mShareActionProvider = (ShareActionProvider) item.getActionProvider(); return true; } // Call to update the share intent private void setShareIntent(Intent shareIntent) { if (mShareActionProvider != null) { mShareActionProvider.setShareIntent(shareIntent); } } above lines
@Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); actionBarDrawerToggle.syncState(); } } menu file is here
