Toolbar navigation icon never set

Question

I m trying the new Toolbar component and having some trouble with the navigation icon  I want to implement a custom icon for back navigation   In my manifest i set a parent to my activity    lt activity android name  quot  CardsActivity quot  android parentActivityName  quot  MainActivity quot  gt       lt  -- Parent activity meta-data to support API level 7  -- gt       lt meta-data         android name  quot android support PARENT ACTIVITY quot          android value  quot  MainActivity quot    gt   lt  activity gt   I declare the toolbar like this    lt RelativeLayout xmlns android  quot http   schemas android com apk res android quot      xmlns tools  quot http   schemas android com tools quot      android layout width  quot match parent quot      android layout height  quot match parent quot      android paddingBottom  quot  dimen activity vertical margin quot      tools context  quot com example lollitest MainActivity quot   gt            lt android support v7 widget Toolbar         android id  quot   id my awesome toolbar quot          android layout height  quot wrap content quot          android layout width  quot match parent quot          android minHeight  quot  attr actionBarSize quot          android layout marginBottom  quot 10dp quot          android background  quot  attr colorPrimary quot    gt        lt TextView         android layout width  quot wrap content quot          android layout height  quot wrap content quot          android layout below  quot   id my awesome toolbar quot          android text  quot  string hello world quot    gt    lt  RelativeLayout gt   Then in my activity i configure the Toolbar like this   Toolbar toolbar    Toolbar  findViewById R id my awesome toolbar   toolbar setNavigationIcon R drawable ic good   toolbar setTitle  quot Title quot    toolbar setSubtitle  quot Sub quot    toolbar setLogo R drawable ic launcher   setSupportActionBar toolbar    Which giving me    The back icon is not the one i set with setNavigationIcon     Whatever drawable i give to the method the navigation icon is always the back arrow  I have tried to remove the parent association in the manifest but the only effect is  obviously  to prevent the button to go back  On contrary if i want the default back arrow icon and don t call setNavigationIcon   i don t have any icon at all  What is the correct way to handle the navigation icon in toolbar  custom and default    NOte   i m running my test on Android 4 4

Remove this line from activity if you have added    Override     protected void onPostCreate Bundle savedInstanceState            super onPostCreate savedInstanceState              Sync the toggle state after onRestoreInstanceState has occurred          mDrawerToggle syncState            Then set icon    getSupportActionBar   setHomeAsUpIndicator icon

Specific to the navigation icon  this is the correct order     get the actionbar as Toolbar and set it up Toolbar toolbar    Toolbar  findViewById R id signIn toolbar   setSupportActionBar toolbar     Inform the Toolbar to provide back navigation  This will set the icon to the default material icon  getSupportActionBar   setDisplayHomeAsUpEnabled true     Later override the icon with the custom one  in my case the Holo back icon  toolbar setNavigationIcon R drawable ic chevron left white 36dp

I had simillar problem  After a big headache I found  that my ActionBarDrawerToggle was modifying the icon  also when it should not modify the icon  because I didn t give reference to toolbar to the toggle component   So  in my NavigationDrawerFragment class  that handles the opening and closing  in setUp      method I set  mDrawerToggle setHomeAsUpIndicator R drawable app icon    and finally it worked

Currently you can use it  changing the order   it seems to be a bug   Toolbar toolbar    Toolbar  findViewById R id my awesome toolbar   setSupportActionBar toolbar    toolbar setNavigationIcon R drawable ic good   toolbar setTitle  Title    toolbar setSubtitle  Sub    toolbar setLogo R drawable ic launcher

I used the method below which really is a conundrum of all the ones above  I also found that onOptionsItemSelected is never activated       mDrawerToggle setDrawerIndicatorEnabled false       getSupportActionBar   setHomeButtonEnabled true        Toolbar toolbar    Toolbar  findViewById R id tool bar       if  toolbar    null            toolbar setNavigationOnClickListener new View OnClickListener                  Override             public void onClick View v                    onBackPressed
