Android apk 簽名

##加簽名##

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 已簽名。」則成功

問題：

一、jarsigner: 沒法對 jar 進行簽名: java.util.zip.ZipException: invalid entry compressed size (expected 47019 but got 48319 bytes)

緣由：應爲次apk包已經被簽過名。

##驗證簽名##

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

##對齊##

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