RecyclerView with Glide fast scroll results OutOfMemory (OOM)

Question

I have a RecyclerView. The row in the recyclerview contains an ImageView. I'm using Glide to load the images (size is 30-80 KB / image). If I scrolling from top to the bottom I get OutOfMemoryException in the end. The test device is quite old: Samsung Galaxy S3.

I know there is plenty of similar questions. I've tried them all, but I haven't been successful so far.

The RecyclerView is in a fragment in a ViewPager (with 2 pages).

Row's layout:

...
 <ImageView
    android:id="@+id/catch_pic"
    android:layout_width="0dp"
    android:layout_height="@dimen/_250sdp"
    android:layout_marginTop="8dp"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/description"/>
...

My adapter:

...
@Override
public void onBindViewHolder(@NonNull final RecyclerView.ViewHolder holder, int position) {
    final Catch actualCatch = mItems.get(position);

    CatchViewHolder catchHolder = (CatchViewHolder) holder;

    if (actualCatch.getCatchPic() != null && !actualCatch.getCatchPic().isEmpty()) {
        catchHolder.mCatchPic.setVisibility(View.VISIBLE);

        Glide
            .with(catchHolder.itemView.getContext())
            .load(BASE_URL_FOR_IMAGES.concat(actualCatch.getCatchPic()))
            .apply(new RequestOptions().transforms(new CenterCrop(), new RoundedCorners(30)).skipMemoryCache(true))
            .into(catchHolder.mCatchPic);
    } else {
        catchHolder.mCatchPic.setVisibility(View.GONE);
    }
}

@Override
public void onViewRecycled(@NonNull RecyclerView.ViewHolder holder) {
    super.onViewRecycled(holder);

    CatchViewHolder catchHolder = (CatchViewHolder) holder;

    Glide.with(holder.itemView.getContext()).clear(catchHolder.mCatchPic);
}
...

Logcat detail(while scrolling):

I slowly go mad. Can anybody help me where is the error?

Edit #1:

If I temporarily limit the ViewPager to 1 fragment, the result is the same:

Is `onViewRecycled` invoked ? Looks like due to fast scrolling, too many images are being loaded resulting in OOM. Instead try overriding `destroyItem` as mentioned in [this](https://github.com/bumptech/glide/issues/679) thread. Moreover, since you are using viewPager, is there possible heavy lifting going on there ? You might try to allocate one pager at a time in memory — NightFury, Feb 07 '19 at 18:57
Thank you for your answer. I've completed my question. Yes, the onViewRecycled invoked. — wyzard, Feb 07 '19 at 19:11
In `onViewRecycled` perhaps also try setting the ImageView drawable to null? `catchHolder.mCatchPic.setImageDrawable(null)` — sbearben, Feb 07 '19 at 21:22
