 <!-- 上传服务 -->

        <service
            android:name="com.evt.services.ServicesUpload"
            android:enabled="true"
            android:exported="false" >
            <intent-filter>
                <action android:name="com.evt.services.ServicesUpload" />
            </intent-filter>
        </service>



activity中：



private ServicesUpload servicesUpload; // 上传服务



Intent intent = new Intent("com.evt.services.ServicesUpload");
 bindService(intent, conn, Context.BIND_AUTO_CREATE);



ServiceConnection conn = new ServiceConnection() {


 @Override
 public void onServiceConnected(ComponentName arg0, IBinder arg1) {
 // TODO Auto-generated method stub
 servicesUpload = ((ServicesUpload.ServicesUploadBinder) arg1)
 .getServicesUpload();
 }


 @Override
 public void onServiceDisconnected(ComponentName name) {
 // TODO Auto-generated method stub


 }


 };


 @Override
 protected void onDestroy() {
 // TODO Auto-generated method stub
 unbindService(conn);
 super.onDestroy();
 }



调用方法：



servicesUpload.startDownLoad();
