and how to fix it ?

i found this issues:https://github.com/couchbase/couchbase-lite-java-core/issues/97#issuecomment-62040966

but i have try to clean the document cache,it will crash again.

 Database db = DBController.getInstance().getCouchDatabase();

            if (db != null) {

                try {

                    entity.save(db);

                } catch (CouchbaseLiteException e) {

                    db.clearDocumentCache();

                    entity.save(db);

                }

            }

It's preventing you from clobbering a later revision that was added.  This can happen if you have the following situation:

* Show user rev1 of document in UI

* Couchabse lite sync's rev2 of doc in background

* You try to save user's changes, based off rev1 (which is now stale)

* Couchbase Lite throws that error, since you passed in rev1 as the previous revision, but rev1 is no longer the latest revision it knows about.

Does that sound like what's happening in your case?

If you debug it, you should see that you are trying to save a revision based on a stale previous revision.  If not, it might be a bug in Couchbase Lite worth looking into.

Can you produce some standalone code that reproduces the problem?

My some code here:

  public static void updateCardReviewInCouchBase(CardReviewInfoDocument entity) {

        try {

            Database db = DBController.getInstance().getCouchDatabase();

            if (db != null) {

                try {

                    Log.e("TAG", "updateCardReviewInCouchBase: " + entity.getId());

                    entity.save(db, new AbstractDocument.OnDocumentPersistenceListener() {

                        @Override

                        public void onBeforeSave(Map<String, Object> properties) {

                            Log.e("TAG", "onBeforeSave:properties:" + properties.toString());

                        }

                        @Override

                        public void onAfterSave(Document document) {

                            Log.e("TAG", "onAfterSave:properties:" + document.getProperties().toString());

                        }

                    });

                } catch (CouchbaseLiteException e) {

                    db.clearDocumentCache();

                    entity.save(db);

                }

            }

        } catch (CouchbaseLiteException e) {

            e.printStackTrace();

        }

    }

update method:

     public final void save(Database database, OnDocumentPersistenceListener callback) throws CouchbaseLiteException {

        if (callback != null) {

            callback.onBeforeSave(mProperties);

        }

        // Create document if required

        if (mDocument == null) {

            mDocument = database.createDocument();

        }

        // com.couchbase.lite.CouchbaseLiteException: Conflicts not allowed and there is already an existing doc with id: 1180a204-bddd-4ea8-9070-5b24fd17f2de

        mDocument.putProperties(mProperties);

        if (callback != null) {

            callback.onAfterSave(mDocument);

        }

    }

I think  if i save  (mDocument.putProperties(mProperties)) error. at this time  i can try call the update method ( mDocument.update(new Document.DocumentUpdater())).

and i found the log:
