Answer 1

コードからgetSupportActionBar().setHomeButtonEnabled(true)を削除するだけです。

FYIActionBarDrawerToggleには、引き出しアイコンの代わりにランチャーアイコンR.mipmap.ic_launcherが使用されています。

これを試してみてください：

...................... 
    ........................... 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

    mDrawerToggle = new ActionBarDrawerToggle(
         this,       
         mDrawerLayout,     
         R.drawable.YOUR_DRAWER_ICON, /* nav drawer icon to replace 'Up' caret */ 
         R.string.drawer_open,   
         R.string.drawer_close) { 
     public void onDrawerClosed(View view) { 
      getSupportActionBar().setTitle(mTitle); 
      invalidateOptionsMenu(); 
     } 

     public void onDrawerOpened(View drawerView) { 
      getSupportActionBar().setTitle(mDrawerTitle); 
      invalidateOptionsMenu(); 
     } 
    }; 

    mDrawerLayout.setDrawerListener(mDrawerToggle);
