Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead

I'm trying to set up a toolbar with a burger menu, this is my code,and
the error is:


This Activity already has an action bar supplied by the window decor.
Do not request
Window.FEATURE_SUPPORT_ACTION_BAR
and set
windowActionBar to false in your theme to use a Toolbar instead.


The problem is that I don't know where I am getting the error from, and
also the fact that I tried everything.

MainActivity.java

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
txResult = (TextView) findViewById(R.id.txResult);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);}

// Set a Toolbar to replace the ActionBar.


// Find our drawer view



private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
selectDrawerItem(menuItem);
return true;
}
});
}

public void selectDrawerItem(MenuItem menuItem) {
// Create a new fragment and specify the planet to show based on
// position
Fragment fragment = null;

Class fragmentClass;
switch(menuItem.getItemId()) {
case R.id.nav_first_fragment:
fragmentClass = MainActivity.class;
break;
case R.id.nav_second_fragment:
fragmentClass = SecondActivity.class;
break;
case R.id.nav_third_fragment:
fragmentClass = ThirdActivity.class;
break;
default:
fragmentClass = MainActivity.class;
}

try {
fragment = (Fragment) fragmentClass.newInstance();
} catch (Exception e) {
e.printStackTrace();
}

// Insert the fragment by replacing any existing fragment
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.flContent, fragment).commit();

// Highlight the selected item, update the title, and close the drawer
menuItem.setChecked(true);
setTitle(menuItem.getTitle());
mDrawer.closeDrawers();
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
// The action bar home/up action should open or close the drawer.
switch (item.getItemId()) {
case android.R.id.home:
mDrawer.openDrawer(GravityCompat.START);
return true;
}

return super.onOptionsItemSelected(item);
}

Answer

You don't need this:

<item name="windowActionBar">false</item>

Your theme parent Theme.AppCompat.Light.NoActionBar already declares that there is no action bar (but a toolbar).
