ActionBarDrawerToggleHoneycombpublic class ActionBarDrawerToggleHoneycomb extends Object | This class encapsulates some awful hacks.
Before JB-MR2 (API 18) it was not possible to change the home-as-up indicator glyph
in an action bar without some really gross hacks. Since the MR2 SDK is not published as of
this writing, the new API is accessed via reflection here if available. |
