// 检测网络

public static boolean checkNetworkAvailable(Context context) {
ConnectivityManager connectivity = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity == null) {
return false;
} else {
NetworkInfo[] info = connectivity.getAllNetworkInfo();
if (info != null) {
for (int i = 0; i < info.length; i++) {
if (info[i].getState() == NetworkInfo.State.CONNECTED) {
NetworkInfo netWorkInfo = info[i];
if (netWorkInfo.getType() == ConnectivityManager.TYPE_WIFI) {
return true;
} else if (netWorkInfo.getType() == ConnectivityManager.TYPE_MOBILE) {
return true;
}
}
}
}
}

return false;
}
