repositories{

mavenCentral()

}

dependencies {

 compile ('com.google.android.gms:play-services-maps:10.0.1')

}

按以上配置，運行clean時報錯，無法加載play-services-maps 10.0.1包。
點擊Android Studio的提示如何修復(fù)的鏈接，就會自動下載Google的相關(guān)依賴包到本地。下載時彈出窗口中顯示的一些信息如下。

1.public boolean shouldOverrideUrlLoading(WebView view, String url) { 
       view.loadUrl(url);
       return true;
  }
重寫shouldOverrideUrlLoading方法，返回true表示點擊鏈接是在當前webview里打開，而不是調(diào)用瀏覽器打開


WebViewClient與WebChromeClient的區(qū)別 http://blog.csdn.net/jackyhuangch/article/details/8310033

1. Android Studio2.2在mac下啟動報錯
找不到原因，改為使用Android Studio 2.1.3
下載地址：http://tools.android.com/download/studio/builds/2-1-3

2. 編譯某項目報錯Could not find property 'config' on SigningConfig container
在build.grade文件的android->signingConfigs節(jié)點下增加config配置
    }
...

3. 編譯報錯failed to find target android-22
修改build.grade文件的相關(guān)屬性：

參考dubbo里的NetUtils類
