问题 I have a small issue regarding Ethernet . My three questions are: Can we programmatically Turn-On/Off Ethernet ? Can we programmatically Enable/Disable Ethernet ? Can we programmatically Connect Ethernet ? The above Questions are done with the Wifi . Like We can programmatically Turn-On/Off Wifi . We can programmatically Enable/Disable Wifi . We can programmatically Connect Wifi using WifiManager . Does android provides any EthernetManager like as WifiManager to handle Ethernet ? Or, if this

问题 To check for internet connectivity, i am using this code: public boolean isOnline() { ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo netInfo = cm.getActiveNetworkInfo(); //return netInfo != null && netInfo.isConnectedOrConnecting(); return netInfo != null && netInfo.isAvailable() && netInfo.isConnected(); } This is the most commonly used code i found everywhere - however it is not working reliably. This is returning true, although i

问题 I am using this code to setup a proxy for my WebView on Android and it is working well. I have modified the code to use an exclusion list. On devices using the android.net.ProxyProperties I am passing an exclusion list like ".google.com,.bing.com" and on devices using the System properties I am passing " .google.com| .bing.com". It is all working fine on ICS, and Lollipop but I can not get it to work on KitKat. I don't have 4.2/4.3 devices to test on but I'll try it on an emulator later,

问题 When I run this piece of code on Android 2.3.6, it works fine. On 4.0 I get a StrictMode exception. From some questions on SO, seems like you cant do network operations on the UI thread. But I am not doing any UI operation on the UI thread. I am calling doBackground directly and not execute, since I need to check the return value of the doBackground. I guess the below should have worked. What am I missing here ? handler.postDelayed(new Runnable() { @Override public void run() { God

问题 I am having some strange issues when I want to verify, whether an Android device is connected to a specific Wi-Fi (identified by SSID) AND it has a MOBILE data network active at the same time. It is also likely that my issue is connected to Android 9 (SDK 28), as I did not get any complaints from users with previous Android versions. So here is what I have: This is my main method, that should tell me whether the device is currently connected to it's target Wi-Fi: public boolean

问题 I have commad-line tool, which sends broadcast and wait result. Server code (error handling omitted): int makeAddr(const char* name, struct sockaddr_un* pAddr, socklen_t* pSockLen) { int nameLen = strlen(name); pAddr->sun_path[0] = '\0'; strcpy(pAddr->sun_path+1, name); pAddr->sun_family = AF_LOCAL; *pSockLen = 1 + nameLen + offsetof(struct sockaddr_un, sun_path); return 0; } int main(int argc, char* argv[]) { //... // Create socket in abstract namespace struct sockaddr_un sockAddr = {0};

问题 I want to show alert that connection not available in my android application. I am calling some rest request in my application. To check this network unavailability scenario I manually disconnect my wifi in my laptop (I am testing in simulator) . Code where I call service is here resp = client.execute(httpPostRequest); and here I am catching exception catch (IllegalStateException e) { //assertTrue(e.getLocalizedMessage(), false); e.printStackTrace(); } catch (ClientProtocolException e) { /

问题 I have an activity which needs to perform an operation once a connection to a network has been established. I tried implementing the Observer pattern but am getting a NullPointerException when I try to register the Observer activity to the subject. Any thoughts? NetworkStatus public class NetworkStatus implements NetworkStatusSubject, Runnable { List<NetworkObserver> observerList; Context context; public NetworkStatus(Context context) { this.context = context; } public static boolean
