Answer 1

After 3 days of struggle i found a solution for not increasing Heap memory by using this

i replace all my ImageView like this

<com.example.util.SingleShotImageView
                    android:id="@+id/grid_image"
                    android:layout_width="170dp"
                    android:layout_height="240dp"
                    android:adjustViewBounds="true"
                    android:layout_centerInParent="true"
                     />

Using this class i use to clear the Image bitmap heap size in onDetachedFromWindow function

public class SingleShotImageView extends ImageView {

    public SingleShotImageView(Context context) {
        super(context);
    }

    public SingleShotImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public SingleShotImageView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onDetachedFromWindow () {
        setImageDrawable(null);
        setBackgroundDrawable(null);
        setImageBitmap(null);
        System.gc();
    }

}

now it works fine and my heap memory remains
