चूंकि अपाचे पुस्तकालय को हटा दिया गया है , उन लोगों के लिए जो उपयोग करना चाहते हैं HttpURLConncetion, मैंने इस उत्तर की मदद से गेट और पोस्ट अनुरोध भेजने के लिए इस वर्ग को लिखा है :

if (msCookieManager.getCookieStore().getCookies().size() > 0) {
//While joining the Cookies, use ',' or ';' as needed. Most of the server are using ';'
conn.setRequestProperty(COOKIE ,
TextUtils.join(";", msCookieManager.getCookieStore().getCookies()));
}
