    Hi all

    I'm new to here and i hope i can get some help. I not searched the forums for similar topics cause i do not have much time, so please forgive me if this question asked before.

    So, I want to check that the network connection is alive on the phone from program but when i try to run this code
    Code (Text):
    2. private boolean isOnline() {
    3.         ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    4.         NetworkInfo netInfo = cm.getActiveNetworkInfo();
    5.         if (netInfo != null && netInfo.isConnectedOrConnecting()) {
    6.             return true;
    7.         }
    8.         return false;
    9.     }
    I get the message "Sorry 'Appname' is stopped unexpectedly. Try again"
    Can someone help me with this?


    I might have to search the solution elsewhere, i added permissions for network, run the application and got the same error but when i tried to start it from the menu it said application not installed.

    Thank you

    You need to add the following lines to your manifest:
    Code (Text):
    2. <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    3. <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
