web view 有缓存啊&br&//设置 缓存模式&br&webView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT); &br&// 开启 DOM storage API 功能 &br&
webView.getSettings().setDomStorageEnabled(true); &br&这样你就可以在返回前一个页面的时候不刷新了

先打开界面然后关闭网络再刷新一次就能辨别出来是原生还是web了，是web的话就会显示网页无法访问之类的，原生的那些界面控件还在。

社交帐号登录用Okhttp框架登录之后的Cookie设置到webView无效?
如题，我自己的安卓应用中，使用到的请求框架是Okhttp，登录是用该框架请求的，然后有将cookie保存起来，应用中有页面使用webview，然后需要将cookie设置到webview中去。现在的情况是网上找的各种方法都有试过，但是一直无效，webview加载url的时候依然会跳转到网页端的登录页面。求各路大神解决。
安卓WebView用的是谷歌的浏览器内核，可以看成是内嵌进去的chrome，由于谷歌的安全机制，安卓WebView的cookie在本地是访问不了的，我们项目的hybrid，本地文件是放在asset文件夹里，所以读写不了cookie，不知道你的是不是

Android提供了WebView控件展示web页面的能力，还可通过WebViewClient类辅助WebView处理各种通知、请求。
核心代码：
mWebView = (WebView) findViewById(R.id.WebView);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl(&&);
Activity文件
package com.app.
import android.app.A
import android.os.B
import android.view.KeyE
import android.webkit.WebV
import android.webkit.WebViewC
import android.widget.T
* WebView控件
* @author 402-9
public class WebViewTest extends Activity{
private WebView webV
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);//设置使用够执行JS脚本
webView.getSettings().setBuiltInZoomControls(true);//设置使支持缩放
webView.getSettings().setDefaultFontSize(5);
webView.loadUrl(&http://10.0.2.2:8888/csdn/&);
webView.setWebViewClient(new WebViewClient(){
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);// 使用当前WebView处理跳转
//true表示此事件在此处被处理，不需要再广播
@Override //转向错误时的处理
public void onReceivedError(WebView view, int errorCode,
String description, String failingUrl) {
// TODO Auto-generated method stub
Toast.makeText(WebViewTest.this, &Oh no! & + description, Toast.LENGTH_SHORT).show();
@Override //默认点回退键，会退出Activity，需监听按键操作，使回退在WebView内发生
public boolean onKeyDown(int keyCode, KeyEvent event) {
// TODO Auto-generated method stub
if ((keyCode == KeyEvent.KEYCODE_BACK) && webView.canGoBack()) {
webView.goBack();
return super.onKeyDown(keyCode, event);

In my Android app, I am trying to switch from android-async-http to okhttp which supports async networking sind version 2.0. While the former ships with an implementation of a , I don't know how to implement something like this for okhttp.
In my app I have a login routine during which a get request is sent that, if successful, should set a cookie. This cookie should be appended to all subsequent network requests and should survive application restarts.
on SO, indicating that the following piece of code, if executed somewhere in the app, activates persistent cookie management and okhttp would use it:
CookieManager cookieManager = new CookieManager();
cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);
CookieHandler.setDefault(cookieManager);
However, for me it does not work. Is the CookieManager the right way to go? How could I monitor which cookies were set and stored to further debug the issue?

You can set your CookieStore in the OkHttp client with the following code:
OkHttpClient client = new OkHttpClient();
client.setCookieHandler(new CookieManager(
new PersistentCookieStore(getApplicationContext()),
CookiePolicy.ACCEPT_ALL));
trying to improve
in two points:
the URI should not be used if the domain and path attributes of the cookies are available.
In SerializableHttpCookie class the HttpCookie httpOnly attribute is not serialized (it does not have accessors nor mutators). My solution was to use reflection to be able to access this private attribute.
Putting the code into a custom Application's onCreate function solves the issue. It works now.
public class MyApplication extends Application {
public void onCreate() {
super.onCreate();
// enable cookies
java.net.CookieManager cookieManager = new java.net.CookieManager();
cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);
CookieHandler.setDefault(cookieManager);
I managed to get persistent cookies with okhttp with the following CookieStore, which is partly copied from the one of android-async-http. It works with API lvl 9 and maybe fewer.
