getDataFromCache(...) not working about robospice

[rciovati]

Could you post a simple project that reproduces this?

You can reproduce this issue with:

1. checkout robospice-sample-spring-android
2. I'm using Gson instead of Jackson
3. put following lines of code in your MainActivity class:

    @Override
    protected void onResume() {
        super.onResume();
        ListTweets tweets;
        try {
            Future<ListTweets> task = contentManager.getDataFromCache(ListTweets.class, "tweets.android");
            tweets = task.get();
        } catch (CacheLoadingException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        }
    }

4 search with the query "android"
5 you get an ANR error

Was you spiceManager started before reaching this line ?

Also, please consider the asynchronous nature of a call to
getDataFromCache. When you call this method, it will return a future as the
spiceManager must bind to the spiceService and, when bound, ask for the
cache content.

When you call the method get() of that future, it will block until the
getDataFromCache actually completes. This operation should not be called on
the main thread but inside an AsyncTask. Otherwise, get will block your UI
thread and create an ANR. There is no workaround for it.

I was writing what @stephanenicolas said.

BTW, you can use the getFromCachemethod that is async. ;)
We use it in the same sample: http://bit.ly/WrhFNn

Right. Thx Ricardo. ;)

OK, so there is no possibility to get cached data synchronously?
