wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside

that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor

<h2>Documentation</h2>
Add this to your xml
<com.larswerkman.colorpicker.ColorPicker
android:id="@+id/picker"
android:layout_width="285dp"
android:layout_height="290dp"/>
To change the thickness of the wheel and the pointer you can add this.
app:wheel_size="2"
app:pointer_size="4"
To get the color of the colorpicker
ColorPicker picker = (ColorPicker) findViewById(R.id.picker);
picker.getColor();
