repositories{

mavenCentral()

}

dependencies {

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

}

按以上配置，运行clean时报错，无法加载play-services-maps 10.0.1包。
点击Android Studio的提示如何修复的链接，就会自动下载Google的相关依赖包到本地。下载时弹出窗口中显示的一些信息如下。

1.public boolean shouldOverrideUrlLoading(WebView view, String url) { 
       view.loadUrl(url);
       return true;
  }
重写shouldOverrideUrlLoading方法，返回true表示点击链接是在当前webview里打开，而不是调用浏览器打开

1. Android Studio2.2在mac下启动报错
找不到原因，改为使用Android Studio 2.1.3
下载地址：http://tools.android.com/download/studio/builds/2-1-3

2. 编译某项目报错Could not find property 'config' on SigningConfig container
在build.grade文件的android->signingConfigs节点下增加config配置
    }
...

3. 编译报错failed to find target android-22
修改build.grade文件的相关属性：
