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(); }
