In your log I see this line: 在您的日志中，我看到以下行：
06-09 07:22:06.009 1334-1334/Abc.com I/art: Rejecting re-init on previously-failed class java.lang.Class<com.itextpdf.awt.PdfGraphics2D>
Notice awt . 注意awt 。 AWT is a part of Java that is not available on Android. AWT是Java的一部分，在Android上不可用。 You are using iText for Java (which version???) but you should use the Android port instead, iTextG. 您正在使用Java的iText（哪个版本？？？），但应改用Android端口iTextG。 It is functionally identical to iText, but with all the things stripped out that aren't available on Android. 它在功能上与iText相同，但是剔除了所有在Android上不可用的功能。
iTextG is available on Maven Central: https://mvnrepository.com/artifact/com.itextpdf/itextg so you can use it in Gradle, or whatever your favorite build system is. iTextG在Maven Central上可用： https ://mvnrepository.com/artifact/com.itextpdf/itextg，因此您可以在Gradle或任何您喜欢的构建系统中使用它。
