Re: Delete Persistent Data when the app is uninstalled

Hi Friends,


I have the same issue. I delete the app & then reinstall from the command prompt then it show the previous data.


public static class MyIntHashtable extends IntHashtable implements Persistable {


 public static IntHashtableStore getInstance(long UID) {

        PersistentObject  po = PersistentStore.getPersistentObject(UID);    
        IntHashtable store = (IntHashtable) po.getContents();

        if (store == null) {
            store = new MyIntHashtable();
        return store;



Can some tell me how can I resolve it. When i delete app data should be deleted & when i reinstall the app then i dont face the old data.


Thanks In Advance
