我的应用程序上显示了一张图片，而另一张图片没有显示，但是两张图片都可以从浏览器中访问。
在我的免费主机上的这张图片无法在我的应用程序中显示。请注意，我可以从免费主机服务器上看到该图片：
http://www.justedhak.comlu.com/images/uploaded_images.jpg
这是从一个随机网站上获取的内容，它正在应用程序中显示。
http://api.androidhive.info/json/movies/1.jpg
我的问题是，我上传图片的方式有问题吗？还是免费主机（000webhost）有问题？请给我您的意见。
我将图片上传到服务器，然后在活动中显示url，但它没有在应用程序中显示。然而，我添加了另一个图像URL，它在应用程序中显示。
这是获取URL图像的代码。

try {
JSONObject jsonObj = new JSONObject(myJSON);

for(int i=0;i<peoples.length();i++){

String url = c.getString(TAG_PATH);
Listitem.add(new Listitem(id,url));
}

// gridView.setAdapter(gridAdapter);

这是上传图片
