Jarsigner: ANDROIDS缺少签名块

Question

我已经签署了apk，但是当我试图使用jarsigner验证时：

jarsigner -verify -verbose -certs sample.signed.apk

但我说错了：

jarsigner: Signature Block missing for ANDROIDS

我不知道该在哪里调查这个问题。谁能给我个提示吗？

Answer 1

原来我在JDK1.6上使用的jarsigner版本。在我把它升级到1.7之后。问题解决了。

Answer 2

你是怎么在jar文件上签名的？

在Java文档中，这里看起来像

-verify
   If this appears on the command line, the specified JAR file will 
   be verified,not signed. If the verification is successful,
   "jar verified" will be displayed. If you try to verify an unsigned
   JAR file, or a JAR file signed with an unsupported algorithm 
   (e.g., RSA when you don't have an RSA provider installed), 
   the following is displayed: "jar is unsigned. (signatures  
   missing or not parsable)" It is possible to verify JAR files 
   signed using either jarsigner or the JDK 1.1 javakey tool, or both.
