Question

我想在我的真实设备Android上运行我的应用，但收到此错误：

我安装了Android sdk，并在Windows7中添加了我的Path：

C:\Development\android-sdk\platform-tools;
C:\Development\android-sdk\tools;
C:\Development\android-sdk\android-sdk

问题出在哪里???

Answer 1

似乎仅与代理有关。您可以通过两种方式设置代理。

创建/修改gradle.properties @ c:\Users\<username>\.gradle\

OR

转到您的项目位置，并执行与上述相同的操作

示例：platforms/android/gradle.properities

在文件

systemProp.http.proxyHost=proxyhost
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=username
systemProp.http.proxyPassword=pwd
systemProp.http.nonProxyHosts=*.nonproxyrepos.com|localhost
systemProp.https.proxyHost=proxyhost
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=username
systemProp.https.proxyPassword=pwd
systemProp.https.nonProxyHosts=*.nonproxyrepos.com|localhost

Answer 2

此链接帮助了我：http://forum.ionicframework.com/t/proxy-error-when-downloading-gradle-zip-during-ionic-emulate-android/31701

要查找.gradle，请转到您的用户文件夹（默认为c:\Users\<your login>）。如果gradle.properties不存在，只需创建一个

Answer 3

查看您的堆栈跟踪，它似乎是某种连接问题。您的计算机是否正在使用任何代理连接到网络？如果是，则必须为您的构建工具配置。我可以看到它只是试图下载 gradle-2.2.1-all.zip ，并且由于连接问题而失败。

解决方案：在nodejs中配置代理的步骤

npm config set proxy http://proxy.company.com:8080

npm config set https-proxy http://proxy.company.com:8080

希望信息对您有所帮助。
