我有一个网络服务，我正在使用ksoap2连接到它并上传一些图片。
过程是：
问题： 一切顺利。上传并显示上传的项目......直到...突然通知才会从栏中消失。
过了一段时间它再次显示并继续上传，我试着设置一些东西来上传最后一项并从那里开始，我不知道我做得对，我想有一个关于此的建议。
这是我致电服务的活动：
Intent mServiceIntent = new Intent(this, UploadService.class);
Bundle bund = new Bundle();
bund.putStringArray("pathList", pictureList);
bund.putString("tags", tag);
boolean hasGeotag = UserManagerClass.UserLogged.isActiveLocation();
bund.putBoolean("hasGeotag", hasGeotag);
if (hasGeotag) {
GeoTag gtag = UserManagerClass.UserLocation;
bund.putDouble("latitude", gtag.getLatitude());
bund.putDouble("longitude", gtag.getLongitude());
bund.putString("city", gtag.getCity());
bund.putString("country", gtag.getCountry());
bund.putString("address", gtag.getAddress());
}
bund.putInt("idOwner", IDOWNER);
bund.putInt("idUser", UserManagerClass.UserLogged.getID());
bund.putInt("albumindex", albumIndex);
bund.putInt("privacyindex", privacyIndex);
bund.putString("comment", comment);
mServiceIntent.putExtras(bund);
startService(mServiceIntent);

}

savePosition();
String mes = sp.uploadPicture(dataup, tags, SoapPost.UPLOAD_PICTURE, pic);
Log.e("picID", mes);

updateNotification(false);
Thread.sleep(1 * 1000);

现在通知不会隐藏，直到所有文件都上传...谢谢。
