        ItemAdapter adapter = new ItemAdapter(this, itemObject);

        // Get a reference to the ListView, and attach the adapter to the listView.

                Intent intent = new Intent(Handicrafts.this,

        switch(item.getItemId())
        {
            case R.id.paint:
                Intent paintIntent=new Intent(Handicrafts.this,MainActivity.class);
                startActivity(paintIntent);
                break;
            case R.id.covers:
                Intent collageIntent=new Intent(Handicrafts.this,collages.class);

        Items currentItems = getItem(position);

        TextView nameTextView = null;
        if (gridview != null) {
            nameTextView = (TextView) gridview.findViewById(R.id.product_name);

Probable duplicate of this post. Try to recycle bitmap of your ImageView before you update your iconView's drawable. But first of all consider using view holder approach as a best practice for simple ListView and GridView controls — Cool Soft

15451212 byte allocation -- this is equivalent to a 1965 x 1965 pixel image. This is much too large. If this is coming from your resources, either they are too large or are in the wrong directory. — CommonsWare

Try to use RecyclerView and ViewHolder approach and you can also use Picasso or Glide library to smooth loading of image into ImageView. You are tying to show images in a grid manner, so I think you can use RecyclerView and make the RecyclerView LayoutManager in stack format.

 compile 'com.github.bumptech.glide:glide:3.7.0'
 compile 'com.squareup.picasso:picasso:2.5.2'
 compile 'com.android.support:recyclerview-v7:25.3.1'

Have a look at this - https://guides.codepath.com/android/using-the-recyclerview Let me know if any problem occur!

your_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="and.com.bakingtime.activity.MainActivity">

   <android.support.v7.widget.RecyclerView
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:id="@+id/recycler_view" />
</LinearLayout>

list_item.xml

<android.support.v7.widget.CardView
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/card_view"
    android:layout_width="80dp"
    android:layout_height="wrap_content"
    card_view:cardUseCompatPadding="true"
    card_view:cardCornerRadius="8dp"
    android:layout_marginBottom="16dp">
        <ImageView
            android:id="@+id/photo"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:scaleType="centerCrop" />
 </android.support.v7.widget.CardView>

your_adapter_class.java

public class your_adapter_class extends RecyclerView.Adapter<RecyclerViewHolders> {

    private List<ItemObject> itemList;
    private Context context;

    public RecyclerViewAdapter(Context context, List<ItemObject> itemList) {
        this.itemList = itemList;
        this.context = context;
    }

    @Override
    public RecyclerViewHolders onCreateViewHolder(ViewGroup parent, int viewType) {

        View layoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item, null);
        RecyclerViewHolders rcv = new RecyclerViewHolders(layoutView);
        return rcv;
    }

    @Override
    public void onBindViewHolder(RecyclerViewHolders holder, int position) {
        Picasso.with(context).load((itemList.get(position).getPhoto()).into(holder.thumbnail);
    }

    @Override
    public int getItemCount() {
        return this.itemList.size();
    }
}

your_ViewHolder.java

public class your_ViewHolder extends RecyclerView.ViewHolder{

    public ImageView thumbnail;

    public RecyclerViewHolders(View itemView) {
        super(itemView);
        thumbnail = (ImageView)itemView.findViewById(R.id.photo);
    }
}

MainActivity.java
In your MainActivity onCreate making a GridLayoutManager and attaching it to your recyclerView

      private GridLayoutManager lLayout;

      // inside onCreate
       List<ItemObject> rowListItem = getAllItemList();
        lLayout = new GridLayoutManager(MainActivity.this, 2);

        RecyclerView rView = (RecyclerView)findViewById(R.id.recycler_view);
        rView.setLayoutManager(lLayout);

        RecyclerViewAdapter rcAdapter = new RecyclerViewAdapter(MainActivity.this, rowListItem);
        rView.setAdapter(rcAdapter);

    //getAllItemList method
    private List<ItemObject> getAllItemList(){

    List<ItemObject> itemObject = new ArrayList<ItemObject>();

    itemObject.add(new ItemObject("",R.drawable.a1));
    itemObject.add(new ItemObject("",R.drawable.a2));
    itemObject.add(new ItemObject("",R.drawable.a3));
    itemObject.add(new ItemObject("",R.drawable.a4));
    itemObject.add(new ItemObject("",R.drawable.a5));

    itemObject.add(new ItemObject("",R.drawable.a6));
    itemObject.add(new ItemObject("",R.drawable.a7));
    itemObject.add(new ItemObject("",R.drawable.a8));
    itemObject.add(new ItemObject("",R.drawable.a9));
    itemObject.add(new ItemObject("",R.drawable.a10));
    itemObject.add(new ItemObject("",R.drawable.a11));
    itemObject.add(new ItemObject("",R.drawable.a12));
    itemObject.add(new ItemObject("",R.drawable.a13));
    itemObject.add(new ItemObject("",R.drawable.a14));
    itemObject.add(new ItemObject("",R.drawable.a15));

    itemObject.add(new ItemObject("",R.drawable.a16));
    itemObject.add(new ItemObject("",R.drawable.a17));
    itemObject.add(new ItemObject("",R.drawable.a18));
    itemObject.add(new ItemObject("",R.drawable.a19));

    return ItemObject;
