How to close Objectbox Store and delete data files

Question

I'v got an exception after I call put() with my data list.
I know that I closed the box before with a reason (deleteAllFiles() must be closed).
How should I open it again? As I see, dataBoxStore is not null after I closed it.

My code:

dataBoxStore = MyObjectBox.builder().androidContext(this).name("DB").build();

dataBoxStore.close();
dataBoxStore.deleteAllFiles();

final Box<Data> areaLocationBox = dataBoxStore.boxFor(Data.class);
areaLocationBox.put(myList);

Exception:

 Caused by: java.lang.IllegalStateException: Store is closed
    at io.objectbox.BoxStore.checkOpen(BoxStore.java:261)
    at io.objectbox.BoxStore.beginTx(BoxStore.java:310)
    at io.objectbox.Box.getWriter(Box.java:107)
    at io.objectbox.Box.put(Box.java:389)

With ObjectBox 1.3 this got simpler. You can use one of the static BoxStore.deleteAllFiles methods without initiating a BoxStore:

BoxStore.deleteAllFiles(context, "DB");

dataBoxStore.put(myList);

Throw the exception of Store is closed while and dataBoxStore is not null.

What I found is to initiate the boxStore again to use it:

dataBoxStore = MyObjectBox.builder().androidContext(this).name("DB").build();

dataBoxStore.close();
dataBoxStore.deleteAllFiles();

dataBoxStore = MyObjectBox.builder().androidContext(this).name("DB").build();
final Box<Data> areaLocationBox = dataBoxStore.boxFor(Data.class);
areaLocationBox.put(myList);

If someone can find another option to solve it just tell me. but as I see there is no any function to open the boxStore without to initiate it again. – motis10 Nov 22 '17 at 14:57
It is OK. I just realized that the static `deleteAllFiles` method with `File`parameter is not really usable for Android. Will think about that for upcoming 1.2.2 release. – Markus Junginger Nov 22 '17 at 15:47
@MarkusJunginger Great. So can you mark it as the correct answer for now? – motis10 Nov 22 '17 at 16:24
Will be deprecated in hopefully a few hours... :-) – Markus Junginger Nov 22 '17 at 16:35
@MarkusJunginger did it fix? If so please update the answer or please mark it as current answer. – motis10 Nov 23 '17 at 23:16
Done interally, but for the release, we'll have to finish something else first. – Markus Junginger Nov 24 '17 at 11:13
