I asked a question about how to update Volley cache in Android yesterday and no one answered it, and I can not find any documentation about updating cache in Volley. I'm wondering if maybe I misunderstood the way cache could be updated or not.
How can I update Volley cache?
EDIT:
just for clarification, i bring my code below to explain my issue:
private void checkCache(String service_address, final int termId, int node_Id) { Cache cache = MyApplication.getInstance().getRequestQueue(true).getCache(); Cache.Entry entry = cache.get(service_address); /* cache is full- maybe new maybe old */ if (entry != null) { if(networkChecker.isConnected()) { Calendar calendar = Calendar.getInstance(); long serverDate = MyApplication.getInstance().getRequestQueue(false).getCache().get(service_address).serverDate; if (Utility.getMinutesDifference(serverDate, calendar.getTimeInMillis()) >= 30) { MyApplication.getInstance().getRequestQueue(false).getCache().invalidate(service_address, true); //does this code referesh cache?how to referesh cache for new incomming data } } ShowOrUpdateBadger(); pDialog.hide(); } /* //cache is empty---- should get all news */ else { /* can not fetch data-->close app */ if (!networkChecker.isConnected()) { pDialog.cancel(); Utility.ShowFaildMessage(MainActivity.this); } /* load from internet */ else { GetonlineNewGalleryData(service_address, termId, true, node_Id); } } } I call above method in my application's opening in onCreate() in MainActivity. The question is, in below code, how can I update cache with new news?
if (entry != null) { ... } EDITE:
I update my code ,and my code is like below:
private void checkCache(String service_address, final int termId, int node_Id) { Cache cache = MyApplication.getInstance().getRequestQueue().getCache(); Cache.Entry entry = cache.get(service_address); if(networkChecker.isConnected()) { if(entry!=null) { MyApplication.getInstance().getRequestQueue().getCache().invalidate(service_address,true); MyApplication.getInstance().getRequestQueue().getCache().remove(service_address); } GetonlineNewGalleryData(service_address, termId, true, node_Id); } else { if(entry==null) { pDialog.cancel(); Utility.ShowFaildMessage(MainActivity.this); } else { ShowOrUpdateBadger(); pDialog.hide(); } } Now the problem is , my cache data was 400 news and new data is 2 news after doing update cache my cache number is 802 news!
