最近在做一个项目，涉及html5和native交互，交互过程中会出现上面的log。

前提：

1.一个activity有七屏，每一屏对应一个Fragment，每一个Fragment对应一个webview

2.每一个webview都执行了该方法

mWebView.addJavascriptInterface(new NativeHtml5(getActivity()), "js2java_android");

现象：

1.点击首页内容后，就出现闪退。log为以上。

解决办法：

1.一个activity只保持一个NativeHtml5 对象。即不要每一个Fragment就new 一个js接口。
