加载webview 退出再进去显示不全

再退出之前做清除操作 不然会因为上一个js的缓存 导致加载不出来

mWebView.clearHistory();

mWebView.clearFormData();

mWebView.clearCache(true);

//webView.destroy();

CookieSyncManager cookieSyncManager = CookieSyncManager.createInstance(mWebView.getContext());

CookieManager cookieManager = CookieManager.getInstance();

cookieManager.setAcceptCookie(true);

cookieManager.removeSessionCookie();

cookieManager.removeAllCookie();
