1 在三星手機上出現這個問題，其他手機沒發現問題。

java.lang.IllegalStateException: Call CookieSyncManager::createInstance() or create a webview before using this class 清除Cookie或者獲取Cookie前，首先同步。

報錯程式碼：

public String getCookies(Context context, String domain, String key){
		//獲取Cookie
		CcookieManager cookieManager = CookieManager.getInstance();
		String cookie = cookieManager.getCookie(domain);
		return cookie;
	}
 

修改後:[清除Cookie前，首先同步]

public String getCookies(Context context, String domain, String key){
		//首先同步Cookie
		CookieSyncManager cookieSyncManager = CookieSyncManager
				.createInstance(context);
		cookieSyncManager.startSync();
		cookieSyncManager.sync();
		//獲取Cookie
		CookieManager cookieManager = CookieManager.getInstance();
		String cookie = cookieManager.getCookie(domain);
		return cookie;
	}
 

參考：[Android清除cookie報錯java.lang.IllegalStateException: Call CookieSyncManager::createInstance() or create a webview before using this class]
