안드로이드 문제의 도넛 차트

Question

안녕하세요, 저는 안드로이드에서 도넛 차트를 만들고 싶습니다. 나는 좋은 모범을 보았습니다. 라이브러리를 추가했는데 프로젝트에 오류가 표시되지 않습니다. 그러나 같은 것을 실행하는 시점에 logcat에서 다음과 같은 오류가 발생합니다.

당신이 당신의 소스 코드와 그것을하는 고해상도/xml 디렉토리가 있는지 확인하십시오 아래 XML 파일이 있습니다.

chart.xml

<?xml version="1.0" encoding="utf-8"?> 
<ai:chart xmlns:ai="http://www.artfulbits.com/android/aiCharts"> 
    <ai:area /> 
    <ai:series type="Doughnut" showLabel="true"/> 
    <ai:title text="Doughnut ingredients"/> 
</ai:chart>
