How to remove dark line and gradient under action bar

Question

How do i remove this line under the action bar?
_{(source: android.com)}

I would like it to be a solid color like the way google+ or the below app is:

i have tried

<item name="windowContentOverlay">@null</item>
<item name="android:windowContentOverlay">@null</item>

But that doesnt seem to remove it. All i want to do is just use a solid color, no tiled image, no gradient.

they this code it is override Background of actiobar

ActionBar actionBar = getSupportActionBar();
actionBar.setBackgroundDrawable(getResources().getDrawable(
            R.drawable.actionbar));

drawable/actionbar.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#06B697" />
</shape>
