FirestorePagingAdapter crashes when scrolling in version 8.0.1

After updating FirebaseUi from implementation 'com.firebaseui:firebase-ui-firestore:8.0.0' to implementation 'com.firebaseui:firebase-ui-firestore:8.0.1' FirestorePagingAdapter crashes when I scroll the RecyclerView. I think it always crashes at the same position, maybe at this position it loads new items for the first time.
I get the following crashlog:
java.lang.IllegalStateException: The same value, PageKey{StartAfter=1MbZLsOSoWUPAdDnNOGlthxGjDC2 - 02:52:33 - 11.04.2022, EndBefore=null}, was passed as the nextKey in two
sequential Pages loaded from a PagingSource. Re-using load keys in
PagingSource is often an error, and must be explicitly enabled by
overriding PagingSource.keyReuseSupported.

TextView with clickablespan throwing exception on long click

I've a TextView in my app where every word is a clickable span. Everything works fine until I long click any word, which throws the following exception:

I've tried setting android:longClickable="false" on the TextView but in vain. Any idea how it can be fixed?
Thanking in anticipation!

Android App crash because of Null Pointer exception on setting onClick listener in Editor class

I have created a Linear Layout onclick of a button which has an edit text. While typing there is a popup window for suggestions that comes up and the app crashes.
Stack trace:

I found some related answers which stated that this happens on using Android PopupWindow class since the suggestions are using a PopupWindow as well. My code does not use PopupWindow as well.
This crash is happening mostly on Samsung Note 5, and Galaxy S6.
Any help would be appreciated!

It's saying that your button (which you used like buttonName.setOnClickListener()) is not defined. Check your find view by id function, id inside of it etc.

I think it is because you set in XML a click, but don't have in your class. A check has this tag and remove:
android:onClick="save"

Android Weird Null Object Reference on Button.setText(mText)

I'm stuck with the weirdest error I've ever got since I started programming. I'm setting a text to a button. Nothing complicated there!
I do it this way:
btnButton.setText(cell.getText());
btnButton exists since I've passed some others things to it before setting its text and cell.getText() is not null either since I can log the text in my console.
Still, I get this weird error:

Can someone help me fix this? It sometimes work but it depends from where in the application that I come from.
Thanks!
EDIT
Here's my whole code when creating the button. I assign it's width and initial text and then if the text should be truncated, I measure to make sure that my button will still fit in the size I gave it otherwise, I change it to textView.
It's when I set it back to normal after that it gives me the error.
Button btnButton = new Button(getActivity());
btnButton.setWidth(width);
btnButton.setText(cell.getText());
if(adjustedAutogrid.getColumn(indexCell).isTruncated()){
btnButton.setText("…");
btnButton.measure(0, 0);
if(btnButton.getMeasuredWidth() > width){
TextView btnText = new TextView(getActivity());
btnText.setWidth(width);
btnText.setText(cell.getText());
cell.getCSS().applyToTextView(btnText);
btnText.setEllipsize(TextUtils.TruncateAt.END);
btnText.setLines(1);
layout.addView(btnText);
break;
}
btnButton.setText(cell.getText());
btnButton.setEllipsize(TextUtils.TruncateAt.END);
btnButton.setLines(1);
}
And for those wondering from where it causes problem, well it's a bit complicated. I receive information through internet (an XML) that I convert to a table that I show. I must set the different cells the appropriate size and content. When I load what we call an AutoGrid coming from the XML, all my AutoGrid works except for one...
Edit 2
Everything works fine if I leave the text to the ellipsize symbol (…). It really is when i try to set the text again that it doesn't work..

I don't know why but it seems that if I set the text later with my button that everything is fine...
btnButton.setWidth(width);
btnButton.setEllipsize(TextUtils.TruncateAt.END);
btnButton.setLines(1);
btnButton.setText(cell.getText()); // this line used to be the first one
If someone has an explanation, please fill free to enlighten me!
