本例不含依赖工程的情况，如有依赖工程，请先导出为jar包再打包：
1. 基于Android 2.1以上版本；
2. 签名的密钥文件生成；
1）. 创建证书：keytool -genkey -alias mykey.keystore -keyalg RSA -keystore mykey.keystore 密码同系统登陆密码
3）. 查看证书库：keytool -list -keystore mykey.keystore
4）. 导出到证书文件：keytool -export -alias mykey.keystore -file mykey.crt -keystore mykey.keystore
5）. 导入证书的信息：keytool -import -keystore mykey.keystore -file mykey.crt mykey.crt导入到名为mykey.keystore的证书库中
6）. 查看证书信息：keytool -printcert -file mykey.crt
7）. 删除密钥库中的条目：
keytool -list -keystore mykey.keystore
keytool -delete -keystore mykey.keystore -alias mykey.keystore
8）. 修改证书条目的口令：keytool -keypasswd -alias mykey.keystore -keystore mykey.keystore
