connectivity

I am using the following code to check for the internet connection through out my app. public class ConnectionChangeReceiver extends BroadcastReceiver { @Override public void onReceive( Context context, Intent intent ) { ConnectivityManager connectivityManager = (ConnectivityManager)context.getSystemService( Context.CONNECTIVITY_SERVICE ); NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo(); NetworkInfo mobNetInfo = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE ); if (activeNetInfo != null) { Toast.makeText( context, "Active Network Type : " +

I want to write a script, that would keep checking if any of the devices in network, that should be online all day long, are really online. I tried to use ping, but if [ "`ping -c 1 some_ip_here`" ] then echo 1 else echo 0 fi gives 1 no matter if I enter valid or invalid ip address. How can I check if a specific address (or better any of devices from list of ip addresses) went offline? StianE Ping returns different exit codes depending on the type of error. ping 256.256.256.256 ; echo $? # 68 ping -c 1 127.0.0.1 ; echo $? # 0 ping -c 1 192.168.1.5 ; echo $? # 2 0 means host reachable 2 means

I would like to test my application for cases of low network connectivity. Except standing in the elevator, what is the best way to do this? I've tried wrapping my phone in an aluminum foil, but it didn't help much. I need to test it on a real device, not in an emulator. inazaruk You can use emulator for this. Take a look at this page: Android Emulator . Pay attention to next two arguments: -netdelay <delay> Set network latency emulation to . Default value is none. See the table in Network Delay Emulation for supported values. -netspeed <speed> Set network speed emulation to . Default value is

I am developing an application which connects to the server. By now the login and data transmission works fine if theserver is available. The problem arises when the server is unavailable. In this case the method sends a login request and waits for the response. Does anyone know how to check if the server is available (visible)? The pseudocode of the simple logic that has to be implemented is the following: String serverAddress = (Read value from configuration file) //already done boolean serverAvailable = (Check if the server serverAddress is available)//has to be implemented (Here comes the

This question already has an answer here: Check INTENT internet connection 12 answers I am making an app where a user is uploading information and files to my server on a somewhat frequent basis. This is done in new threads through a dedicated uploader service. I know from this thread Detect whether there is an Internet connection available on Android that you can check if there is an internet connection relatively easily. You can also get socketTimeoutExceptions to detect internet connectivity issues. All that is well and good, and lets me cache my uploads easily enough when the connection
