서비스에서 이어폰 연결여부를 확인합니다. 연결되면  SafeEarphone.java 메인 액티티가 실행되게끔

이어폰이 연결되어있지않으면 Main.java 액티비티가 실행되게끔 했습니다.

아래는 Main.java 소스입니다.

  package com.ksh.SafeEarphone;import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.Window;public class Main extends Activity { /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  requestWindowFeature(Window.FEATURE_NO_TITLE);
  setContentView(R.layout.start);
    startService(new Intent("com.ksh.SafeEarphone"));
  Handler handler = new Handler () {
    
            @Override
            public void handleMessage(Message msg)
            {
                // TODO Auto-generated method stub
                super.handleMessage(msg);
                finish();
            }
        };
        handler.sendEmptyMessageDelayed(0, 2500);
        // TODO Auto-generated method stub 
 }}

Manifest에는 아래와같이 작성했습니다.

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
 package="com.ksh.SafeEarphone" android:versionCode="1"

SafeEarphone.java 에는 건드리지않아 이상이없구요.

어플실행시 이어폰은 꽂지않은 상태에서는 잘되는데

이어폰이 연결된상태에서 실행하면 애플리케이션이 예상치않게 중단 되었습니다. 다시시도해주세요. 하면서 안되네요..

어떻게 해야 될까요??ㅠ_ㅠ 도와주세요~
