ActionBarDrawerToggle icon missing when using AppCompat v22

Question

I'm using Appcompat v22 to use tinted style for AutoCompleteTextView. However, as soon as I changed my build.gradle from this:

compile 'com.android.support:support-v4:21.0.3'
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.android.support:cardview-v7:21.0.2'
compile 'com.android.support:recyclerview-v7:21.0.2'

to this:

compile 'com.android.support:support-v4:22.0.0'
compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.android.support:gridlayout-v7:22.0.0'
compile 'com.android.support:cardview-v7:22.0.0'

The ActionBarDrawerToggle Icon (Hamburger icon) goes missing. (However, if I slide from left, the drawer gets revealed)

Inside onCreate():

    mDrawerLayout = (BBDrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
    mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
            R.string.drawer_open, R.string.drawer_close) {
        @Override
        public void onDrawerClosed(View drawerView) {
            super.onDrawerClosed(drawerView);
            toolbar.setTitle(mTitle);
            invalidateOptionsMenu();
        }

        @Override
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            trackEvent(TrackingAware.MENU_SHOWN, null);
            toolbar.setTitle(mDrawerTitle);
            invalidateOptionsMenu();
        }
    };

    mDrawerLayout.setDrawerListener(mDrawerToggle);

Have also called syncState()

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    if (mDrawerToggle != null) {
        mDrawerToggle.syncState();
    }
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    if (mDrawerToggle != null) {
        mDrawerToggle.onConfigurationChanged(newConfig);
    }
}

If I downgrade the appcompat version back to 21.0.3, everything starts to work.

When you say "everything starts to work", are you talking about the icon? — Jared Burrows, Mar 16 '15 at 11:55

The relevant part is in the last line of code, I have them in my Activity.onCreate(..) method:

    _drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, 0, 0);
    drawerLayout.setDrawerListener(_drawerToggle);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

As I remember that line is documented too but in appcompat v21 they were ignored (or at least the default was different..)

I'm having this same problem. The only thing that seems to make the home button show up is calling setDisplayHomeAsUpEnabled(true). When I do that, I see the hamburger icon, and when I click it, it acts as the back button. I'm thoroughly confused. – M Dapp May 19 '15 at 20:16
This doesn't seem to solve it for me. I'm already calling: getSupportActionBar().setDisplayHomeAsUpEnabled(true); getSupportActionBar().setHomeButtonEnabled(true); – waterlooalex May 30 '15 at 18:20
Figured it out, I was using v4 AppCompat ActionBarDrawerToggle which is deprecated, I upgraded to v7 and it works now – waterlooalex May 30 '15 at 18:33

For those encountering the same problem as Dapp (toggle showing back arrow instead of hamburger icon), this is most likely because you're missing a drawerToggle.syncState() in your Activity.

To be more specific, you have to override the onPostCreate() method like this :

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    drawerToggle.syncState();
}

This isn't the only method that needs to be overriden. See this post by jpardogo for more details.

also be sure to use the right theme on your actionbar...if your actionbar is dark, the default icon might be black unless you do this: "@style/ThemeOverlay.AppCompat.Dark.ActionBar"

It bit me, but only on Android 4.x devices (5.x+ worked fine oddly enough)
