We used need to check the user's net is work before we need to connect the work. how can we do this?

Just see the code:

Private void checkNet () {ConnectivityManager cm = (ConnectivityManager) this. getSystemService (Context. CONNECTIVITY_SERVICE); NetworkInfo info = cm. getActiveNetworkInfo (); if (info! = Null & info. isConnected () {Toast. makeText (this, "net is working", 0 ). show ();} else {Toast. makeText (this, "net isn' t work", 0 ). show (); // jump to the setting Intent intent = new Intent (); intent. setClassName ("com. android. setting "," com. android. settings. wirelessSettings "); startActivity (intent );}}

And u need to add the permission to ur AndroidManifest. xml:

Android. permission. ACCESS_NETWORK_STATE
