Problems using PieChart of achartengine

I'm facing problems using PieChart from the achartengine library. According to 开发者_运维知识库the demo, the PieChart extends AbstractChart.java, not AbstractChart.class in the library. Hence, the functions buildCategoryRenderer(int[] args) and buildCategoryDataset(String arg0, double[] arg1) don't exist in the library.

How does one initiate a PieChart and show it as an separate intent?

You can follow the instructions here in order to download and setup the AChartEngine demo into your IDE. Then, take a look at BudgetPieChart. It extends the AbstractChart class that is located into the same demo package.

However, from version 0.6.0, the AbstractChart will be renamed to AbstractDemoChart to avoid naming issues.

I know it is too late, just putting for people stumble up on the same question:
