Re: How to Delete Persistent Store When App is Uninstalled?

you can use custom persistent classes, those will be removed on uninstall.
if you only use inherent persistant classes (like hashtable) they will remain, and there is no known way to remove them.

create a new bean class with a member of type string, implement persistable, and store that instead.

class Bean implements Persistable {
private String stringy;
public String getStringy(){
return stringy;
}
public void setStringy(String stringy){
this.stringy=stringy:
}
}
