No data saved in PERSISTENCE

[ildar2]

There are three Source types: MEMORY, PERSISTENCE and CLOUD; I get results from cloud and memory, but after I close app I lose all data: no data returned from PERSISTENCE. How can I fix/debug this?

[UmarBhutta]

Same is happening with me.

[leejiang1]

I had the same when data encrypted

Are you solve it？ Can you answer me quickly ？

[ildar2]

Yeah, I used something else

What method can you use to achieve the same effect, thanks

I've created interface MbCache to store my object (called Dashboard). Implementation can be any persistence lib. then I just manually saved and retrieved it

    @Inject
    protected MbCache mCache;

    @Inject
    public DataRepository() {
    }

    private boolean dashboardCacheValid;
    private boolean firstTimeDashboardRequested = true;

    public void invalidateDashboardCache() {
        //todo for LocalCache
        Timber.v("dashboard cache invalidated");
        firstTimeDashboardRequested = false;
        dashboardCacheValid = false;
    }

    public Observable<Dashboard> getDashboard(String phoneNum, boolean getNewData) {
        Dashboard fromCache = mCache.getDashboard();
        if (firstTimeDashboardRequested) {
            dashboardCacheValid = fromCache.cacheValid();
            firstTimeDashboardRequested = false;
        }
        if (!fromCache.cacheValid()) invalidateDashboardCache();
        if (dashboardCacheValid && !getNewData) {
            return Observable.just(fromCache);
        } else {
            Observable<Dashboard> observableToCache = Observable.concat(Observable.just(fromCache),
                    mNetworkHelper.getDashboardRaw(phoneNum)
                            .doOnNext(dashboard -> {
                                dashboardCacheValid = true;
                                mCache.putDashboard(dashboard);
                            }));
            return cacheObservable(CACHE_PREFIX_GET_DASHBOARD + phoneNum, observableToCache);
        }
    }

When I manually clear the application's cache and then retrieve the data from the rxcache again, I will not get a data error
