Permission Denied on trying to open a realm in INTERNAL STORAGE

[vyashole]

Goal

I want to investigate this crash.

Expected Results

Permission denied should not occur because my realm is in internal storage with the following config:

        Realm.init(this); //this is application context here
        realmConfig =  new RealmConfiguration.Builder().name("collect.realm").schemaVersion(21).migration(new Migration()).build();

Actual Results

Stacktrace

Note: my proguard mapping file is configured to not include file names, that's why everything is SourceFile

Steps & Code to Reproduce

Never reproduced this manually. Received this stacktrace in our crash reporting tool. Appears to be happening only on Lenovo A7010a48 running Android 6.0. This crash happens when Realm.getDefaultInstance() is called from the onCreate() of my MainActivity, which means the app crashed on launch. init() happens in the Application class. The app is a single process application so there is probably no way for init() to go wrong.

Version of Realm and tooling

Realm version(s): 2.3.1

Realm sync feature enabled: no

Android Studio version: 2.3.3

Which Android version and device: Lenovo A7010a48 running Android 6.0

Hi @adwaitv We have seen a number of bugs with vendors. Most likely it is a bug on that particular device. See e.g #3972 for a possible work-around.

Without further information and a way to reproduce it, I doubt there is much we can do about it, unfortunately 😢

I'll keep this open a little longer as @beeender might remember seeing this error elsewhere or have other ideas.

Dup to #3972 without reproducing it, it is hard to tell why .... could be same reason with #3972 (comment)
