Hi all,
I got an problem on getting the TelephonyManager in my personal service. The
code as below:
public class MyService extends Service {
@Override
public IBinder onBind(Intent intent) {
return mBinder;
}
/**
* The implementation of IMyService defined through AIDL.
*/
public IBinder mBinder = new IMyService.Stub() {
public Map getConfig() {
...
TelephonyManager tel =
(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
...
The code will throw an NullPointerException on the
line: (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
why??
