We started noticing this on Android 8 and 8.1 devices after we upgraded appcompat library from 1.3.1 to 1.4.0. Seems like that the newest library is using a different/newer classes for handling emojis.

Thanks for the report, this is a combination we didn't predict and need to resolve.

 In the current version of the libraries, precomputed text won't work with the presence of emoji in 1.4.0. There is no workaround using precomputed text in the current library, so the best solution is to `setText` as proposed.

Notes for resolution (options discussed):
1. Disabling emoji processing for precomputed text from InputFilter etc
2. Integrate emoji into PrecomputedTextCompat to apply emoji processing prior to precomputation (needs research)

    Unprecompute text when adding emoji
   
    Emoji2 will now unwrap PrecomputedText to add emoji automatically. This
    has the effect of discarding precomputed text when emoji spans are added.
   
    Apps wishing to optimize this may call EmojiCompat.procss manually, then
    avoid the PrecomutedText path if any spans are added.
   
    Relnote: "Emoji2 will add emoji to PrecomputedText by discarding
    previously precomputed text layout."

Can I know in which appcompat version that includes this fix? I'm using appcompat v1.4.1 and suddenly receive a lot of such crash :(

Hi someone is using my device for a business, Google ads, and a YouTube channel. The YouTube is mashup and I found a name in my Facebook where it should have only been my name. Now when I go to look up the emoji comments from the above I'll get a page saying I can't access and it won't let me go.

I'd like to know if you can look into this or how will it go?

When support this? i face the same problem, it multiple query and insert, it'll block

hopefully we'll have this in 2.1 . What is your use case, are you accessing the same database from different processes or are you creating 2 instance of the same RoomDatabase in the same process?

Create one instance of RoomDatabase, and use LiveData paging query the datas and when querying, i also use the db connect insert the data, the query always wait the insert end and return

BTW, other thread insert the data, or update the data

if you are in the same process, don't use multiple RoomDatabase instances.

Why the LiveData been blocked? the query always waiting for the insert end and return

    Multi-instance invalidation
   
    Developers can now sync observers for InvalidationTracker and LiveData
    between multiple RoomDatabase instances by
    RoomDatabase.Builder.enableMultiInstanceInvalidation(). This can also be
    used for database instances in other processes. All the instances have
    to be using the same database file.
   
    When multi-instance invalidation is turned on, all the tables are
    observed by an instance of MultiInstanceInvalidationClient, and
    invalidation detected in one instance is broadcast to other instances by
    remote procedure call.
