Syntax error on tokens, ConstructorHeaderName expected instead & Syntax error on token “(”, < expected

问题

I'm getting two errors stating Syntax error on tokens, ConstructorHeaderName expected instead & Syntax error on token "(", < expected

on the line:

mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);

...any suggestions?

public class DataCountService extends Service {
    String text = "USR;1";
    String ERROR = Constants.PREFS_NAME;
    private Timer timer = new Timer();
    private long period;
    private long delay_interval;




    EndCallListener callListener = new EndCallListener();
    TelephonyManager mTM = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
    mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);

    private class EndCallListener extends PhoneStateListener {
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            if(TelephonyManager.CALL_STATE_RINGING == state) {
              //  Log.i(LOG_TAG, "RINGING, number: " + incomingNumber);
            }
            if(TelephonyManager.CALL_STATE_OFFHOOK == state) {
                //wait for phone to go offhook (probably set a boolean flag) so you know your app initiated the call.
              //  Log.i(LOG_TAG, "OFFHOOK");
            }
            if(TelephonyManager.CALL_STATE_IDLE == state) {
                //when this state occurs, and your flag is set, restart your app
              //  Log.i(LOG_TAG, "IDLE");
            }
        }
    }

回答1:

The line

mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);

is not included in any method. You should put this in the constructor(which seems like what you want) or a regular method.

回答2:

mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);

Should be inside a method, not directly inside class. Refer this question for example implementation.
