Excessive junk system caused by GC on android 2.3.5 during animation

In my application, I have a ViewSwitcher with two children:

<ViewFlipper
    android:id="@+id/galeryviewflipper"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">            
        <ImageView
            android:id="@+id/galeryimageview_0"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:scaleType="fitCenter"
        />
    (... other stuff here)
    </RelativeLayout>

    <RelativeLayout>
    (... copy previous except for IDs)              
    </RelativeLayout>               
</ViewFlipper>

Then I switch the images in the gallery (each photo is 800x600 in size):

//(setup wanted images into ImageViews)
//then:
viewFlipper.setInAnimation(instance, R.anim.fade_in);
viewFlipper.setOutAnimation(instance, R.anim.fade_in);
viewFlipper.setDisplayedChild(nextIndex);

In Android 2.3.4, everything goes as expected, but on the 2.3.5 phone (Galaxy S2) dalvik calls GC several times during the animation, which leads to a sloppy user (pay attention to the GC time and duration!). I do not explicitly name System.gc anyhere in the application.
