应用包名验证
1）下载空白包
2）使用jarsigner生成签名包
jarsigner -verbose -keystore “签名文件.jks” -signedjar “生成的包.apk” “E:\app-release-unsigned.apk（空白包）” 证书别名
jarsigner -verbose -keystore “E:\test.jks” -signedjar “E:\app-release-signed.apk” “E:\app-release-unsigned.apk” test
jarsigner 在 android安装文件中存在 D:\Android\Android Studio\jbr\bin\
