  cache.set("key", "value", 60 * 1000); // It can store things for a minute,
  cache.set("key", "value", 60 * 60 * 1000); // for an hour,
  cache.set("key", "value", 0); // or forever.
  cache.set("key", "value"); // And also for the short version of forever.

  cache.get("key"); // It can get them again,
  cache.remove("key"); // and remove it if you want.

  cache.get("unExistingKey"); // If something doesn't exists, it returns null
  cache.get("tooOldKey"); // The same if a key is too old

  cache.set("AnInteger", new Integer(42)); // You can save all kind of Objects...
  cache.set("ACollection", new ArrayList()); // ...whatever you want

  cache.removeAll(); // You can also clean it,
  cache.size(); // and ask it how many elements it has

  • tray --- (From grandcentrix & Tag is Caching) : a SharedPreferences replacement for Android with multiprocess support. [对系统的SharedPreferences添加多进程支持].

    // create a preference accessor. This is for global app preferences.
    final AppPreferences appPreferences = new AppPreferences(getContext()); // this Preference comes for free from the library
    // save a key value pair
    appPreferences.put("key", "lorem ipsum");

    // read the value for your key. the second parameter is a fallback (optional otherwise throws)
    final String value = appPreferences.getString("key", "default");
    Log.v(TAG, "value: " + value); // value: lorem ipsum

    // read a key that isn't saved. returns the default (or throws without default)
    final String defaultValue = appPreferences.getString("key2", "default");
    Log.v(TAG, "value: " + defaultValue); // value: default

          .useDefaultSerializerInRam(RAM_MAX_SIZE)
                 .noDisk();

  //To put an object into your cache, simply call put
