connectivity - Verfiying Network Connection in Android -


इस सवाल का पहले से ही एक उत्तर है: < 44 उत्तर

मैं जानना चाहता हूँ कि कैसे डेटा भेजने से पहले एंड्रॉइड में नेटवर्क कनेक्शन की पुष्टि करें ? क्या कोई मेरी मदद कर सकता है ? मैं इस कोड की कोशिश करता हूँ, लेकिन कोई भी परिणाम नहीं 

  सार्वजनिक बूलियन हैकनेक्टिंगटोइंटरनेट () (कनेक्टिविटी प्रबंधक कनेक्टिविटी = (कनेक्टिविटी प्रबंधक) ctx.getSystemService (context.CONNECTIVITY_SERVICE); अगर (कनेक्टिविटी! = नल) {NetworkInfo [] info = connectivity.getAllNetworkInfo (); अगर (जानकारी! = नल) {for (int i = 0; i & lt; info.length; i ++) {if (info [i] .getState () == NetworkInfo.State.CONNECTED) {वापस सत्य; }            }         }     }     विवरण झूठा है; }

अपने मेनिफेस्ट की जांच करें: 

  & lt ; उपयोग-अनुमति एंड्रॉइड: name = "android.permission.ACCESS_NETWORK_STATE" / & gt;
