Goal

Sharing a crash log (as reported by Crashlytics) on specific devices.

Expected Results

To verify if my current API usage is correct and hopefully find a resolution.

Actual Results

Code:

public class BaseRealm {
    private RealmConfiguration config = new RealmConfiguration.Builder().build();
    protected Realm mRealm = Realm.getInstance(config);
}

public class RepoImpl extends BaseRealm implements RepoInterface {
    @Override
    public void add(String item) {
        MyPOJO data = new MyPOJO();
        data.setItem(item);
        data.setTimestamp(System.currentTimeMillis());
        mRealm.beginTransaction();
        mRealm.copyToRealmOrUpdate(data);
        mRealm.commitTransaction();
    }
    @Override
    public int getResultCount() {
        return mRealm.where(MyPOJO.class).findAllSorted("timestamp", Sort.DESCENDING).size();
    }
    @Override
    public MyPOJO getItemObjectByIndex(int index) {
        try {
            return mRealm.where(MyPOJO.class).findAllSorted("timestamp", Sort.DESCENDING).get(index);
        } catch (Exception e) {
            return null;
        }
    }
    @Override
    public void remove(int position) {
        mRealm.beginTransaction();
        mRealm.where(MyPOJO.class).findAllSorted("timestamp", Sort.DESCENDING).deleteFromRealm(position);
        mRealm.commitTransaction();
    }
    @Override
    public void closeRealm() {
        mRealm.close();
    }
    @Override
    public Realm getRealm() {
        return mRealm;
    }
    @Override
    public void clearRealm() {
        getRealm().beginTransaction();
        getRealm().deleteAll();
        getRealm().commitTransaction();
    }

The RepoImpl instance is being created from two separate classes and the realm instance is being closed only when onDestroy() is triggered in each of the classes. clearRealm() is currently never called.

Realm version(s): 2.2.1

Android Studio version: 2.2.3

Which Android version and device: Samsung SM-A500F (Android 6.0) and Lenovo S1a40 (Android 4.4.4)

It's seemingly working well on other devices.
