Ich habe gerade versucht, die achartengine-Demo zu verwenden, aber jedes Mal, wenn ich auf etwas klicke, um das Diagramm anzuzeigen, wird die Fehlermeldung "Die Anwendung AChartengine wurde unerwartet beendet. Bitte versuchen Sie es erneut" angezeigt. Jemand weiß mir zu sagen, wie ich es machen kann? Ich habe die Anweisungen auf dieser Seite befolgthttp://www.achartengine.org/content/goodies.html und ich benutze einen Emulator-Standard mit API-Level 7. Ich habe diese Fehler:
