Android - 3D pie chart

Question

My requirements:

• 3D pie chart for an Android device.
• Must work offline.
• Clicking on a separate pie.
• The pie should look like this:

Here is a brief overview of the problems I encountered in order to draw a three-dimensional pie chart.

• Orson Charts . I found one library that can satisfy my need, but it is paid (high rates). ( http://www.object-refinery.com/orsoncharts/android/index.html )

• Google Graphics Library - which draws a pie chart using an API call we don’t want. Our application should work offline. ( https://google-developers.appspot.com/chart/interactive/docs/gallery/piechart

• jFreeChart . This is a java library, but swing packages are used to create graphs. Swing is not included in android, so there is a restriction on the use of this library. ( http://www.java2s.com/Code/Java/Chart/JFreeChartPieChart3DDemo2withRotation.htm )

• aFreeChart . It is intended for the android that used above (jFreeChart), but did not include a 3D drawing for the pie chart. ( http://afreechart.googlecode.com/svn/doc/screenshot/index.html )

Please suggest me if you can use any library.
