为什么要签名app
- android app那么多,要给app一个唯一身份,有了这个唯一身份才能上传到app商店中
- 升级应用时若包名一致但签名不一致，APP也会安装失败
- 所以正式版app都要签名,还有许多我不知道的原因......
注意
- 打包前先检查你的app id,起一个不会和别人重复的名字.很多人还在使用
io.ionic.starter,请赶紧改了.一般命名是com.公司英文名称.应用英文名称
制作签名文件(.keystore文件)
- 使用如下命令生成签名文件
keytool -genkey -v -keystore 你起的名字.keystore -alias 你起的别名 -keyalg RSA -validity 10000
生成签名(.keystore)文件的过程
生成的.keystore文件
使用签名文件
- 把上一部生成的签名文件复制到app根目录下
- 然后在app根目录下创建一个名字为
release-signing.properties的文件,这个文件的内容如下
storeFile=E://work_space//jianshu//ionic2_tabs//ionic2_tabs.keystore
keyAlias=ionic2_tabs
storePassword=ionic2_tabs
keyPassword=ionic2_tabs
打包正式版app(release版)
- 把上一部创建的
release-signing.properties文件复制到./platforms/android根目录下
找不到
./platforms/android目录?执行命令cordova platform add android
- 最后执行
ionic cordova build android -release或ionic cordova build android --prod --release生成正式版app
真正的上线的版本都要使用--prod参数,这会压缩app,使app体积变小,启动更快.缺点是这个参数打包很慢,我这里大概需要5到10分钟
最后
其实release-signing.properties和.keystore文件放到项目根目录是为了方便使用和好写此教程.

你重新生成一个吧,注意你的release-signing.properties中的路径,别名别写错了
