title: How do I change the height of the Android Navigation Bar in the AOSP for Android M?
body: <p>I want to change the height of the Navigation Bar. I am making this change in the Android Framework files. I am changing the values I send in to the following method:</p>
  
  <pre><code>mTmpNavigationFrame.set(0, top, displayWidth, displayHeight - overscanBottom);
  </code></pre>
  
  <p>Located in:</p>
  
  <p><strong>frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java</strong> </p>
  
  <p>But it's not increasing the height. After replacing the binaries, it is working differently. The default keys - back, home, recent - are not visible properly.
  So how do I increase the height without disturbing the existing buttons in the Navigation Bar? </p>
  
  <p>Do I have to make any changes to <strong>.\SystemUI\src\com\android\systemui\statusbar\phone\NavigationBarView.java</strong> of SystemUI instead? Am I doing the changes in the correct place?</p>
