Navigation Drawer Icon (ic_drawer) not showing
Solution 1
I know it is quite late to answer this but this would help someone atleast.
You should probably add these lines of code to show that navigation icon.
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}

Simply put this code in your styles.xml file:
<item name="homeAsUpIndicator">@drawable/ic_drawer</item>
<item name="android:homeAsUpIndicator">@drawable/ic_drawer</item>
I had this same problem and this worked for me.
EDIT
Programmatically you can set:
getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_drawer);
Solution 3
You have to put this code:
getActionBar().setHomeButtonEnabled(true);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeAsUpIndicator(R.drawable.ic_drawer);
or
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_drawer);
I hope that this code help you.

I solved the same issue by having a <meta-data>
specified for my activity but the android:value points to the same Activity.
Hence, if say Activity name is MainActivity then add the below tag to your activity in the manifest file.
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.MainActivity" />
Hope this helps. :)

I am implementing a navigation drawer for my app. Now it works perfectly except for one small glitch. When I set the Navigation Drawer Icon (ic_drawer) to replace the regular "HomeAsUp" caret icon, I still get the arrow. The Nav Drawer icon does not show. I have implemented every method that was on the android developers website. But it doesn't seem to work.
Below is my code:
DrawerLayout mDrawerLayout; FrameLayout leftDrawer, rightDrawer, contentFrame; ActionBarDrawerToggle mDrawerToggle; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_home); initializeViews(); } private void initializeViews() { // TODO Auto-generated method stub mDrawerLayout = (DrawerLayout) findViewById(R.id.mDrawerLayout); mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, R.string.drawer_open_content_desc, R.string.drawer_close_content_desc); getActionBar().setHomeButtonEnabled(true); getActionBar().setDisplayHomeAsUpEnabled(true); mDrawerLayout.setDrawerListener(mDrawerToggle); leftDrawer = (FrameLayout) findViewById(R.id.drawerLeft_frame); rightDrawer = (FrameLayout) findViewById(R.id.drawerRight_frame); contentFrame = (FrameLayout) findViewById(R.id.content_frame); } @Override protected void onPostCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onPostCreate(savedInstanceState); mDrawerToggle.syncState(); } @Override public void onConfigurationChanged(Configuration newConfig) { // TODO Auto-generated method stub super.onConfigurationChanged(newConfig); mDrawerToggle.onConfigurationChanged(newConfig); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.home, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // TODO Auto-generated method stub if (mDrawerToggle.onOptionsItemSelected(item)) { return true; } return super.onOptionsItemSelected(item); }
