Android System Bar Tint KITKAT



Android 4.4(KitKat) introduced translucent system UI styling for status and navigation bars.
Jgilfelt repository on Git-hub demonstrated how to use it.

 Here are the style files-
A. values folder->styles.xml
<resources>

    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.

        <!--
            Theme customizations available in newer API levels can go in

Colors
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="actionbar_bg">#FF0099CC</color>
    <color name="statusbar_bg">#FF0099CC</color>
</resources>

How To Use

1. Make status bar and navigationbar transparent. Make DefaultActivity.java register in Manifest. Use FullBleedTheme.
<activity
     android:name="com.tutorialsface.systembartint.DefaultActivity"
     android:label="@string/default_example"
     android:theme="@style/FullBleedTheme" >
     <intent-filter>
         <action android:name="android.intent.action.MAIN" />
         <category android:name="com.tutorialsface.systembartint.SAMPLE" />
     </intent-filter>

 </activity>

DefaultActivity.java

import android.app.Activity;
import android.os.Bundle;
public class DefaultActivity extends Activity {
      @Override
      protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_default);
            // create our manager instance after the content view is set
            SystemBarTintManager tintManager = new SystemBarTintManager(this);
            // enable status bar tint
            tintManager.setStatusBarTintEnabled(true);
            // enable navigation bar tint
            tintManager.setNavigationBarTintEnabled(true);
      }

}

activity_default.xml

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    android:clipToPadding="false"
    tools:context=".DefaultActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="16dp"
        android:textSize="18sp"
        android:text="@string/text" />

</ScrollView>
2. Make Actionbar and Status bar of Same color. Make MatchActionBarActivity.java and register in Manifest. Use ActionBarTheme
<activity
    android:name="com.tutorialsface.systembartint.MatchActionBarActivity"
    android:label="@string/match_actionbar_example"
