Android WebView 保存cookie 最简单方式

//初始化webView 时调用
/**
 * 设置 cookies
 * @param cookiesPath 请求地址
 */
public void setCookies(String cookiesPath) {
  Map<String, String> cookieMap = new HashMap<>();
  String cookie = getSharedPreferences("cookie", Context.MODE_PRIVATE).getString("cookies", "");// 从SharedPreferences中获取整个Cookie串
  if (!TextUtils.isEmpty(cookie)) {
    String[] cookieArray = cookie.split(";");// 多个Cookie是使用分号分隔的
    for (int i = 0; i < cookieArray.length; i++) {
      int position = cookieArray[i].indexOf("=");// 在Cookie中键值使用等号分隔
      String cookieName = cookieArray[i].substring(0, position);// 获取键
      String cookieValue = cookieArray[i].substring(position + 1);// 获取值

      String value = cookieName + "=" + cookieValue;// 键值对拼接成 value
      Log.i("cookie", value);
      CookieManager.getInstance().setCookie(getDomain(cookiesPath), value);// 设置 Cookie
    }
  }
}
//stop 生命周期调用
/**

private void saveCookie() {
  CookieManager cookieManager = CookieManager.getInstance();
  String cookieStr = cookieManager.getCookie(getDomain(getString(R.string.app_url)));
  SharedPreferences preferences = getSharedPreferences("cookie", Context.MODE_PRIVATE);
  SharedPreferences.Editor editor = preferences.edit();
  editor.putString("cookies", cookieStr);
  editor.commit();
