Hello World,
I'm writing an app, that should get network info on startup. I've
written the following code, however if the phone is in airplane mode,
it keeps crashing allthough I use a try/catch-statement:
public class HelloAndroid extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TelephonyManager tel = (TelephonyManager)
getSystemService(Context.TELEPHONY_SERVICE);
String imsi = "000000000000000";
String networkOperator = "00000";
try {
imsi = tel.getSubscriberId();
networkOperator = tel.getNetworkOperator();
} catch (Exception e) {
alert("Exception",e+"");
}
}
private void alert(String alerttitle, String alertmessage) {
AlertDialog alertDialog = new
AlertDialog.Builder(this).create();
alertDialog.setTitle(alerttitle);
alertDialog.setMessage(alertmessage);
alertDialog.setButton("OK", new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
which) {
return;
} });
alertDialog.show();
}
}
I have also tried isNetworkAvailable method described at
http://www.androidsnippets.org/snippets/78/ but it crashes in airplane
mode, too.
Any hints on how to solve this?
Thanks for any help in advance!
