From source file:com.heniktechnology.hncore.dynamic_data_base.Cache.java

public static synchronized void initialize(Configuration configuration) {
    if (sIsInitialized) {
        HNLoger.info("ActiveAndroid already initialized.");

    sModelInfo = new ModelInfo(configuration);
    sDatabaseHelper = new DatabaseHelper(configuration);

    // TODO: It would be nice to override sizeOf here and calculate the memory
    // actually used, however at this point it seems like the reflection
    // required would be too costly to be of any benefit. We'll just set a max
    // object size instead.
    sEntities = new LruCache<String, Model>(configuration.getCacheSize());

    openDatabase();

    sIsInitialized = true;
