在android_studio运行cordova项目时遇到的问题

一、All packages are not available for download! The following packages are not available:- Package id platforms;android-19

项目运行后报这个错但是还能在模拟器上打开，只是在项目尝试下载这些包下载不了之后，过程很长，在问题二解决后这个问题也没有了 。

二、-source 1.6中不支持diamond运算符，请使用-source 7或更高版本以启用diamond 运算符

解决：修改File->Project Structure->android

三、在html添加script事件无反应，在js里也是

解决：在html中添加script-src * 'unsafe-inline'

        <meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *; img-src 'self' data: content:;script-src * 'unsafe-inline'">

其实控制台当时也有提示，只是不知道啥意思

10-19 09:46:48.370 1606-1606/io.cordova.hellocordova D/SystemWebChromeClient: file:///android_asset/www/index.html: Line 45 : Refused to execute inline event handler because it violates the following Content Security Policy directive: "default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'". Note that 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
