[Internal] Internal error in Firestore (0.6.6-dev).

[superdiazzz]

Environment

• Android device: RedMi
• Android OS version: 4.4.4
• Firebase/Play Services SDK version: 16.0.5
• FirebaseUI version: 4.2.1

Describe the problem:

I switched to using firebase-ui for certain purposes (previously I used firestore only in version 11.8.0). When replacing using Firebase-ui, the firestore used has increased version to 17.1.1 and then crashes

Steps to reproduce: Almost immediately, when connected to firestore realtime events, we get this:

java.lang.RuntimeException: Internal error in Firestore (0.6.6-dev).
        at com.google.firebase.firestore.obfuscated.zzgf.zzb(com.google.firebase:firebase-firestore@@17.1.1:377)

        at android.os.Looper.loop(Looper.java:136)
        at android.app.ActivityThread.main(ActivityThread.java:5111)

I have researched various ways such as "Clear the data in the application manager on the device. Then run the app again." but still the same.

Library

implementation 'com.firebaseui:firebase-ui-firestore:4.2.1'
implementation 'com.google.firebase:firebase-auth:16.0.5'
implementation 'com.google.firebase:firebase-storage:16.0.5'
implementation 'android.arch.core:runtime:1.1.1'

[samtstern]

@superdiazzz could you add this dependency: implementation 'com.google.firebase:firebase-firestore:17.1.3'

And then try again? It may fix your issue and if it does not, we will at least have a better stack trace since releases of 17.1.2 and up are no longer obfuscated (so no more zzgf.foo stuff)

[superdiazzz]

@samtstern now an error with the latest version like this

Process: com.xsamplegarage.app.custom_in, PID: 9330

let me clarify again, this only happens in specific devices like Redmi 4.4.4, and for other devices it works well

[samtstern]

@superdiazzz I can't tell without seeing the rest of your stack trace (there should be a "caused by" section) but it's possible it's the same as this issue: https://github.com/firebase/firebase-android-sdk/issues/115

Could you provide more of the stack trace?

[superdiazzz]

I think this error can be explored in this part, because the action in the callback is skipped, when I check the console there is a log sequence like the following

in addition to the source of my problem, I did the following code in firestore:

DocumentReference docRef = fdb.collection(Constant.FIRESTORE_DOCUMENT_USER).document(username);
        docRef.get().addOnSuccessListener( documentSnapshot -> {
          // my breakpoint did not reach this  
          Log.d(TAG, "readProfile: " + user.toString());

        }).addOnFailureListener(e -> {
            // also my breakpoint did not reach this
            Log.d(TAG, "readProfile: error " + e);

        });

when I debug it is stuck into the "looper" method and debug ends if I continue

[gsoltis]

Huh, that is more interesting. I was unable to produce this using an emulator at the same Android version. I can confirm that the aforementioned class exists on my classpath. Can you double check to confirm that you only have a single version of firestore on your classpath? Maybe run a clean before building again as well?

[gsoltis]

Also, see if you can confirm that the class exists in your copy of the library. My copy of the jar is located at ${HOME}/.gradle/caches/transforms-1/files-1.1/firebase-firestore-17.1.3.aar/23021475f9623405571a5c7c5062d58c/jars, yours may be in a similar location. You can then run jar -tf classes.jar | grep SQLiteSchema. You should see a few classes, including com/google/firebase/firestore/local/SQLiteSchema$$Lambda$2.class.

[superdiazzz]

@gsoltis I have done clean before building but still give the same results. then when I enter into this path C:/Users/User/.gradle/caches/transforms-1/files-1.1/firebase-firestore-17.1.3.aar/fd8376ec33d52550b992cd5c78618cf8/jars then run jar -tf classes.jar | grep SQLiteSchema give me results 'jar' is not recognized as an internal or external command, but when I browse from log error and enter into the jar file. i found a class SQLiteSchema$$Lambda$2, its path as follows C:/Users/User/.gradle/caches/transforms-1/files-1.1/firebase-firestore-17.1.3.aar/fd8376ec33d52550b992cd5c78618cf8/jars/classes.jar!/com/google/firebase/firestore/local/SQLiteSchema$$Lambda$2.class:10 I don't understand why I still get errors like this

[gsoltis]

If you run gradlew.bat app:dependencies can you confirm that you only have one version of Firestore? It seems like you must have multiple versions of the library being loaded if the class exists in the jar but your application can't find it.

[superdiazzz]

@gsoltis gradlew.bat app:dependencies i run this, then i found only one version firestore. I don't have an idea how to clear or renew library on my path.

[gsoltis]

Hmm, I would try a clean and rebuild. If that doesn't work, verify your classpath as the app sees it, possibly with a snippet of code as described here: https://www.mkyong.com/java/how-to-print-out-the-current-project-classpath/

[superdiazzz]

@gsoltis Sorry to give a long response, here is my clashpath. After the file is executed. Do you see duplicates? if I search there is only one firestore

UPDATE I solved my issue after another device trigger similarly crash with new "cause by". But I don't know whether this is an elegant answer. current solution

Just go to disable Instant Run Go to File -> Settings -> Build,Execution, Deployment -> Instant Run -> Uncheck the checkbox for instant run. Run your app once and this apk file work properly..

@superdiazzz thank you for following up and sharing that you were able too solve this issue by disabling Instant Run. You shouldn't have to do this, but it's good to know.

Closing because it doesn't have to do with FIrebaseUI.
