Android-Throwable: A WebView method was called on thread 'JavaBridge'.

错误详情:

01-30 03:36:52.441 12000-12048/cn.h5 D/@@@: e.ttt:java.lang.RuntimeException: java.lang.Throwable: A WebView method was called on thread 'JavaBridge'. All WebView methods must be called on the same thread. (Expected Looper Looper (main, tid 1) {18b9c7c8} called on Looper (JavaBridge, tid 481) {789820c}, FYI main Looper is Looper (main, tid 1) {18b9c7c8})

当出现以上错误后，处于阻塞状态，无任何效果，出现此错误的原因是：

webView.loadUrl("javascript:show(" + json + ")");

解决方法：

runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                       
                        webView.loadUrl("javascript:show(" + json + ")");
                    }
                });
