Java – ResolveInfo getIconResource() gives very strange results (incorrect icon)

I’m creating a list of apps installed on my phone. I’m using PackageManager and ResolveInfo to retrieve all installed applications. Due to memory issues, I use getIconResource() instead of loadIcon().

My question is how to use iconResource int to display the correct icon in the imageView?

Edit: Add code

This is the part where I create a list where installed applications are stored in Arraylist apps

private void loadApps(){
        manager = getPackageManager();
        apps = new ArrayList<AppDetail>();

if(apps.size()==0) {
            Intent i = new Intent(Intent.ACTION_MAIN, null);
            i.addCategory(Intent.CATEGORY_LAUNCHER);
            List<ResolveInfo> availableActivities = manager.queryIntentActivities(i, 0);
            for (ResolveInfo ri : availableActivities) {
                AppDetail app = new AppDetail();
                app.label = ri.loadLabel(manager);
                app.name = ri.activityInfo.packageName;
                app.icon = ri.activityInfo.getIconResource();
                app.allowed = false;
                apps.add(app);
            }
            Log.i("applist", apps.toString());
        }
    }

In the ArrayAdapter, I want to put the icon in the ImageView

ImageView appIcon = (ImageView)convertView.findViewById(R.id.item_app_icon);
            int id = apps.get(position).icon;
            appIcon.setImageResource(id);

This is the result on the phone, which shows strange icons (some apps even use the Google plus icon :

It also gives an error about resource not found:

W/ResourceType:getEntry failed because entryIndex 1 exceeded type entryCount 1
W/ResourceType: Failed to get entry for 0x7f030001 (t=2 e=1) in package 0 (error -2147483647)
W/ImageView: Resource not found: 2130903041

The problem is that I retrieve the image from the wrong place. Here is the code to get the correct icon:

ImageView appIcon = (ImageView)convertView.findViewById(R.id.item_app_icon);
            String packageName = apps.get(position).name.toString();

try {
                Drawable icon = getPackageManager().getApplicationIcon(packageName);
                appIcon.setImageDrawable(icon);
            } catch (PackageManager.NameNotFoundException e) {
                e.printStackTrace();
            }
