iText在Android中合併pdf錯誤

該代碼在Java應用程序中運行良好。但是當我轉移到Android時我無法編譯。錯誤信息：「該類型java.awt.geom.AffineTransform中不能得到解決它間接地從需要的.class文件中引用」在該行：iText在Android中合併pdf錯誤

cb.addTemplate(page, 0, 0);//compile error at this line

然後我試圖註釋掉上面的行...但發生了什麼事情，這次合併的PDF文件是在Android中創建的，但內部沒有內容......只有空白頁。

這是使用的代碼。任何幫助表示讚賞。（嘗試也同時使用droidText並單獨正常iText的罐子...仍然沒有運氣）
