在設備Android上構建時出錯

Question

我想在我的真實設備Android上運行我的應用程序但我收到此錯誤：

Running command: D:\WebStorm\Path\platforms\android\cordova\run.bat ANDROID_HOME=C:\Program Files (x86)\Android\android-sdk JAVA_HOME=C:\Program Files\Java\jdk1.8.0_40 WARNING : No target specified, deploying to device '02c5cabed02456d5'.

我安裝了Android sdk，並在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

問題出在哪兒？？？

Answer 1

這似乎只是代理問題。 您可以通過兩種方式設置代理。

1. 創建/編輯gradle.properties @ c:\\Users\\<username>\\.gradle\\

OR

2. 轉到您的項目位置並執行與上述相同的操作

示例： platforms/android/gradle.properities

3. 在文件中寫下以下內容

 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

這個鏈接幫助了我： http ： //forum.ionicframework.com/t/proxy-error-when-downloading-gradle-zip-during-ionic-emulate-android/31701

要查找.gradle ，請轉到您的用戶文件夾（默認為c:\\Users\\<your login> ）。 如果gradle.properties不存在，只需創建一個

Answer 3

看看你的堆棧跟蹤，它似乎是某種連接問題。 您的計算機是否正在使用任何代理連接到網絡？ 如果是，則必須為您的構建工具配置。 我可以看到它只是試圖下載gradle-2.2.1-all.zip並且由於連接問題而失敗。

解決方案：在nodejs中配置代理的步驟

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

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

希望信息對您有所幫助。
