我是Cordova的新手，并按照本指南尝试了一个示例应用程序： http://cordova.apache.org/docs/en/3.5.0/guide_platforms_android_index.md.html#Android%20Platform%20Guide
不幸的是，我在命令行中收到以下错误：

任何人都可以帮我这个吗？非常感谢你！
答案 0 :(得分：0)
您是否曾阅读过复制到问题中的构建输出？
它包含通常输出错误消息的末尾：
[dx]写输出错误：java.security.NoSuchAlgorithmException：SHA-1 MessageDigest不可用
建立失败
这是因为构建失败而需要调查的错误消息。
接下来，我使用"SHA-1 MessageDigest not available"运行搜索，并在Stack Overflow上找到：
使用WWW搜索引擎可以找到包含此错误消息字符串的更多网页。
在阅读答案和其他一些网页后，我现在知道这个错误消息可能有几个不同的原因。您必须自己找出哪些原因导致构建中的错误消息。
