I'm downloading XML files from the web to display information. Its quite taxing on the battery to download stuff from the internet so I wan't to implement a cache. I looked at the documentation for cachemanager but its not very helpful. Can anyone tell me how to properly use this? Here is what I currently have:
I believe I am adding stuff to the cache correctly. I get the input stream like so: in = OpenHttpConnection(strSearchURL); then I put it in a CacheResult object so I can use the CacheManager to save it. cr = new CacheResult(); cr.setInputStream(in); CacheManager.saveCacheFile(strSearchURL, cr); My problem is getting info from the cache. Here is what I have: CacheResult cr = new CacheResult(); cr = CacheManager.getCacheFile(strSearchURL, null); That gives me a null pointer exception. I think it may have to do with the fact that I am passing in null for the second paramater instead of a Map<String, String>. But I have no idea how to make that Map or what should be in it to get what I want. So, can someone show me a code sample of succesfully using the cachemanager, or tell me how to fix my code and properly add the Map to the getCacheFile call? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
