根据我在Java方面的经验，jarsigner用于为JAVA ARchive（JAR）文件生成签名，并验证签名JAR文件的签名。
令我惊讶的是，Android也使用jarsigner到sign the Android application package(APK)，这与JAR格式不同。
jarsigner是否不要求将二进制文件打包在JAR中？它是如何在引擎盖下工作的？

APK文件只是具有不同内容的zip文件。
Is there a difference between typical a ZIP file and an APK file?

The JAR feature enables the packaging of class files, images, sounds, and
other digital data in a single file for faster and easier distribution. A tool
named jar enables developers to produce JAR files.
(Technically, any zip file can also be considered a JAR file, although when
created by the jar command or processed by the jarsigner command, JAR files
also contain a META-INF/MANIFEST.MF file.)
