Spring for Android Memory issue

I have in a JSON folder on a server about 2000 products. Each one has price,available_sizes and many more entries. For this reason I decide to make an on the fly binding, by using the RESTTemplate class of the Spring for Android framework. This is working perfectly fine. However, I detect with with MAT(Memory Analyzer Tool) that maybe this approach is too heavy for a mobile because detects possible memory leak.

Here there are the Pojo attributes:

@JsonProperty
private String brand;
@JsonProperty
private String colours;
@JsonProperty
private String img;
@JsonProperty
private Float GBP;
@JsonProperty
private String name;
@JsonProperty
private String prodnum;
@JsonProperty
private String sizes;

However, I don't want to use the

   System.gc();

and the other related methods because I read that the reduce the performance. Can anyone help and propose me something that could be memory efficient?

You should only load as many item you can display in the device.

Displaying all item is too much, because user may not read them all.

You display 10 ( for example) and upon scroll to the bottom, you display another 10.

To implement something like this, you can use Pagination in List View.
