在网上搜了大半天，也没能找到出现该警告的确切原因。通过测试发现，如果不加载url就不会出现该警告。突然间有个想法，莫非是跟页面中的html代码有关?
可是，页面是个静态html 页面，只包含几行最基本的代码呀！后来测试加载其他的页面，问题依久重现。可见出现异常的原因跟html页面没有关系
这里是报错相关代码方法所在、
private synchronized void removeMessages(int what) {1676 if (mBlockMessages) {1677 return;1678 }1679 if (what == EventHub.WEBKIT_DRAW) {1680 mDrawIsScheduled = false;1681 }1682 if (mMessages != null) {1683 Throwable throwable = new Throwable(1684 "EventHub.removeMessages(int what = " + what + ") is not supported " +1685 "before the WebViewCore is set up.");1686 Log.w(LOGTAG, Log.getStackTraceString(throwable));1687 } else {1688 mHandler.removeMessages(what);1689 }1690 } 将 mWebView.getSettings()放在loadurl 后面的。。。
mWebView = (WebView) findViewById(R.id.web_view);
// load file
mWebView.loadUrl(SERVER_URL);
mWebView.getSettings().setJavaScriptEnabled(true);
这是网上大多人使用的更改方法。。还是有人这么改成功了//
