Android Realm默认数据库清除

在Realm.deleteRealm(realm.getConfiguration());添加realm.close()如下之前,它就像一个魅力

try {
      realm.close()
      Realm.deleteRealm(realm.getConfiguration());
                //Realm file has been deleted.
} catch (Exception ex){
                ex.printStackTrace();
                //No Realm file to remove.
}
