我正在逐个上传多张图片到服务器。在这行代码bm = BitmapFactory.decodeFile(imagepath);中，我遇到了OOM错误。我每上传一张图片文件后都回收了位图，但仍然出现错误。我的代码有什么问题吗？还有，是否有更好的方法从ArrayList逐个上传多张图片？

System.out.println("sammy_reached_loadNext");
if(finalImages.size()>0){
System.out.println("sammys_imagelist_after: "+finalImages.size());

System.out.println("sammys_current_pic_path "+path);
new UploadSingleImage(path).execute();
}else{
File dir = new File(file_path);
if (dir.isDirectory()){
String[] children = dir.list();
if(children!=null){
for (int i = 0; i < children.length; i++){
new File(dir, children[i]).delete();
