使用webview.canGoBackOrForward无反应，查看log抛了异常。

java.lang.Throwable: A WebView method was called on thread 'JavaBridge'. All WebView methods must be called on the same thread. (Expected Looper Looper called on Looper (JavaBridge), FYI main Looper is Looper (main) )

因为在不同线程中操作了webview导致。除了canGoBackOrForward，goBackOrForward，loadUrl等都可能出现此问题。

解决方法便是抛给主线程来处理，代码如下：

new Handler(Looper.getMainLooper()).post(new Runnable() {
                @Override
                public void run() {
                    // run中代码根据实际情况填写
                    // if (mWebView.canGoBackOrForward(step)) {
                        // mWebView.goBackOrForward(step);
                    // }
                }
            });
