Hello I am running into a silly error and I think I might be missing something. I currently have a list of objects. The objects have a title, description and an image. The title and description display properly, but for some reason the Image won't. I added the objects on another activity and made a list, when the user selects the item they wanted to see it send the id to this new page where it pulls the object. I added a random image as jpg to the application to see if it pulse and it does, but it looks a little weird. Any ideas why the images won't be pulling from the list? Thank you in advance.

JAVA:
CustomOBJ selOBJ = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.det);
Bundle objID = getIntent().getExtras();
for(int x = 0; x < MainActivity.listobjs.size(); x++){

ImageView objPic=(ImageView)findViewById(R.id.img);
Title.setText(selOBJ.getName());
description.setText(selOBJ.getDescription());
objPic.setImageDrawable(selOBJ.getObjPic());
}
CustomOBJ Class:
public class CustomOBJ {
private String objID;
private String name;
private String Description;
private Drawable objPic;
public CustomOBJ(String i, String n, String d, Drawable pic) {
objID = i;
name = n;
Description = d;
objPic = pic;
}
public String getID() { return objID; }
public String getName() {return name;}
public String getDescription() {return description;}
public Drawable getObjPic() {return objPic; }
}
MainActivity:
public void jsonTolist(){
//parse json data
try{
jArray = new JSONArray(welcome.result);
for(int i=0;i<jArray.length();i++){
JSONObject json_data = jArray.getJSONObject(i);
Log.i("log_tag", "title:" + json_data.getString("title")
);
if(listobjs.isEmpty() || isNewsName(listobjs,json_data) == false){
Drawable drawable = LoadImageFromWebOperations(json_data.getString("img"));
selOBJ = new CustomOBJ(json_data.getString("id"), json_data.getString("title"), json_data.getString("desc"), drawable);
listobjs.add(selOBJ);
}
}
}catch(JSONException e){
Log.e("log_tag", "Error parsing data " + e.toString());
}
}
Load Images:
private Drawable LoadImageFromWebOperations(String url){
try{
InputStream is = (InputStream) new URL(url).getContent();
Drawable d = Drawable.createFromStream(is, "src name");
return d;
}catch (Exception e) {
System.out.println("Exc="+e);
return null;
}
}
Sender Side:
Bundle d1 = new Bundle();
d1.putInt("d",0);
Receiver Side:
Bundle objID = getIntent().getExtras();
int x = objID .getInt("d");
if (MainActivity.listobjs.get(x).getID()
.equals(objID.getString("object") ))
{
selOBJ = MainActivity.listobjs.get(x);
}
Before doing this kindly check CustomOBJ class have a valid constructor or not.
