##加签名##

格式：

$ jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore -signedjar my_application_signed.apk my_application.apk alias_name例：jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore D:/xx/key/xx.jks -signedjar e:/app-product-release-signed.apk e:/app-product-release-unsigned.apk alisasxx提示“jar 已签名。”则成功

问题：

1、jarsigner: 无法对 jar 进行签名: java.util.zip.ZipException: invalid entry compressed size (expected 47019 but got 48319 bytes)原因：应为次apk包已经被签过名。

##验证签名##

jarsigner -verify -verbose -certs e:/app-product-release-unsigned.apk

##对齐##

zipalign -v 4 your_project_name-unaligned.apk your_project_name.apk
