IndexOutOfBoundException: Inconsistency detected. Invalid item position 3

[Shajeel-Afzal]

Admobadapter version or commit: 1.2.6 Android compileSdkVersion: 27

I am getting a lot of Crash Reports in Crashlytics about IndexOutOfBoundException and users are also complaining it in the Google Play Store Reviews. I am using AdmobAdapter along with FirebaseUI library, Following is my code:

mAdapter = new FirebaseRecyclerAdapter<LiveScoreModel, RecyclerView.ViewHolder>(options) {

        public LiveVH mLiveVH;

        @Override
        protected void onBindViewHolder(RecyclerView.ViewHolder holder, int position, LiveScoreModel model) {
            mLiveVH = (LiveVH) holder;
            mLiveVH.setLiveMatchInfo(mAdapter.getItem(position));
        }

        @Override
        public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            mLiveVH = new LiveVH(LayoutInflater.from(parent.getContext()).inflate(R.layout.live_match_item, parent, false));
            mLiveVH.setOnDiscussionClickListener(LiveScoreFragment.this);
            mLiveVH.setOnShareClickListener(LiveScoreFragment.this);
            return mLiveVH;
        }

        @Override
        public void onDataChanged() {
            super.onDataChanged();
            if (mAdapter.getItemCount() == 0) {
                mStatefulLayout.showEmpty();
            } else
                mStatefulLayout.showContent();
        }

        @Override
        public void onError(DatabaseError error) {
            super.onError(error);

            switch (error.getCode()) {
                case DatabaseError.DISCONNECTED:
                case DatabaseError.NETWORK_ERROR:
                    mStatefulLayout.showOffline();
                    break;

                case DatabaseError.PERMISSION_DENIED:
                    mStatefulLayout.showEmpty();
                    mStatefulLayout.setEmptyText(R.string.no_permission);
                    break;

                default: {
                    mStatefulLayout.showEmpty();
                    mStatefulLayout.setEmptyText(R.string.something_went_wrong_while_getting_scores);
                }
            }
        }
    };

       int listAdsLimit = 20;
        int adsFrequency = 3
        int firstAdIndex = 2

        List<BannerAdPreset> adPresets = new ArrayList<>();

            adPresets.add(new BannerAdPreset(getString(R.string.recyclerview_banner_ad_unit_1)));
            adPresets.add(new BannerAdPreset(getString(R.string.recyclerview_banner_ad_unit_2)));
            adPresets.add(new BannerAdPreset(getString(R.string.recyclerview_banner_ad_unit_4)));

        mAdapterWrapper = AdmobBannerRecyclerAdapterWrapper.builder(getActivity())
                .setFirstAdIndex(firstAdIndex < 2 ? 2 : firstAdIndex)
                .setNoOfDataBetweenAds(adsFrequency < 2 ? 2 : adsFrequency)
                .setLimitOfAds(listAdsLimit <= 1 ? 3 : listAdsLimit)
                .setTestDeviceIds(((GlobalApplication) getActivity().getApplication()).getTestDeviceIds())
                .setAdPresets(adPresets)
                .setAdapter(mAdapter)
                .build();

        mLiveScoreRV.setAdapter(mAdapterWrapper);

And following is my code for click handling:

LiveScoreModel item;
        if (mAdapterWrapper != null) {
            final AdmobAdapterCalculator adapterCalc = mAdapterWrapper.getAdapterCalculator();
            int fetchingAdsCnt = mAdapterWrapper.getFetchingAdsCount();
            int sourceCnt = mAdapterWrapper.getAdapter().getItemCount();
            position = adapterCalc.getOriginalContentPosition(position, fetchingAdsCnt, sourceCnt);

            item = mAdapter.getItem(position);
        } else {
            item = mAdapter.getItem(position);
        }

        MatchDiscussionActivity.start(getActivity(), item.getTeam1_name(), item.getTeam2_name(),
                (item.getYmid() == null || item.getYmid().isEmpty()) ? item.getMid() : item.getYmid());

And here is the full Crash Report:

Hi @Shajeel-Afzal Plz check if it could be related to your issue https://stackoverflow.com/questions/30220771/recyclerview-inconsistency-detected-invalid-item-position ?

[Shajeel-Afzal]

Thank you @kot331107, I'll try and update here.

[kot331107]

@Shajeel-Afzal any update?

[Shajeel-Afzal]

@kot331107, I have disabled the ads for now. I'll update and let you know once I have Crash Reports.

[Yura-Savchuk]

I received the same crash. It occurred for me when when banner cannot be displayed because of lost internet connection or wrong configuration.

[JuanNova]

In my case I have solved that with the next line:recyclerView.setItemAnimator(null); In your case try to put mLiveScoreRV.setItemAnimator(null); before mLiveScoreRV.setAdapter(mAdapterWrapper); or when you initialize it.

[kot331107]

@JuanNova thx

closing it for now ...

[thirtyyuan]

In my case I have solved that with the next line:recyclerView.setItemAnimator(null); In your case try to put mLiveScoreRV.setItemAnimator(null); before mLiveScoreRV.setAdapter(mAdapterWrapper); or when you initialize it.

What's the different?

I also faced this problem. This problem occurred when we delete some positions without notifying RecyclerView. Finally I was solve my problem with this code binding.mRecyclerView.getRecycledViewPool().clear(); // to clear RecyclerView old cache. Use this code where you are showing your RecyclerView( in Activity, Fragment ). WARNING: use this code before adding ArrayList to RecyclerView. Otherwise, it throws an error. I hope it helps.
