Qachee

Qachee is a generic cache system to use specially for Android Apps. It is just a LRU Memory cache with policy expiration and lots of useful methods.

Instructions - Maven Central

  1. Add this library in your build.gradle:
dependencies {
    compile 'com.github.nicolasjafelle:qachee:1.2'
}

Instructions - Android Library Module

  1. Clone the git repo
  2. Import the "Qachee" module into your Android-gradle project.
  3. Add "Qachee" module in your settings.gradle
  4. DONE

How to Use it

First you need to extends the QacheeableObject which implements the Qacheeable interface, then you have to implements getKey, you can return a String value or anything that make your instance unique, like getClass().getSimpleName() + hashcode()

@Override
public String getKey() {
 Log.i("HASHCHODE", "KEY VALUE FOR " + getName() + "= " + getClass().getSimpleName() + hashCode());
 return getClass().getSimpleName() + hashCode();
}

You can set the Expiration Time Policy, default is:

ExpirationTime.ONE_MINUTE 

Simple in your Application or any place use:

QacheeManager.getInstance().setExpirationTime(ExpirationTime.THIRTY_SECONDS);

Then just simple use QacheeManager to add, remove and get your Qacheeable objects.

Character character = QacheeManager.getInstance().get(getItem(position), Character.class, true);

OR...

// If toArray() returns empty means: there is nothing previously stored.
// If toArray() returns null the stored data is no longer valid.
List<Character> list = QacheeManager.getInstance().toArray(Character.class, true);

if(list == null || list.isEmpty()) {
 new DemoTask(getActivity()).execute();
}else {
 adapter = new CharacterAdapter(list);
 listView.setAdapter(adapter);
}

When your object is stored in the Qachee you do not need to re-add or update it, simple use it. REMEMBER always to check if the object is stored in Qachee, REMEMBER always work with Qachee, like this:

Character selectedCharacter = (Character) listView.getItemAtPosition(pos);
selectedCharacter = (Character) QacheeManager.getInstance().get(selectedCharacter, true);
