Estou tentando usar o ehCache no Android e obtendo o seguinte erro

    at net.sf.ehcache.CacheManager.getInstance(CacheManager.java:907)

aqui está o meu código em que estou tentando inicializar

private static Cache getCache(String cacheName) throws IllegalStateException{
    CacheManager cacheManager = CacheManager.getInstance();
    Cache cache;
    if(!cacheManager.cacheExists(cacheName)) {
        cacheManager.addCache(cacheName);
    }
    cache = cacheManager.getCache(cacheName);
    return cache;
}

Parece que o EHCache não funcionará no Android? Alguém pode colocar alguma luz nisso? Depois que recebi o erro, também coloquei um ehcache.xml com alguma configuração em res / xml / Theehcache.xml

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="true"  monitoring="autodetect" dynamicConfig="true">

    <!-- By default, Ehcache stored the cached files in temp folder. -->    <!-- <diskStore path="java.io.tmpdir" /> -->

    <!-- Ask Ehcache to store cache in this path -->    <!--<diskStore path="c:\\cache" /> -->

    <!-- Sample cache named cache1
    This cache contains a maximum in memory of 10000 elements, and will expire
    an element if it is idle for more than 5 minutes and lives for more than
    10 minutes.

    If there are more than 10000 elements it will overflow to the
    disk cache, which in this configuration will go to wherever java.io.tmp is
    defined on your system. On a standard Linux system this will be /tmp" 
    -->     
    <cache name="cache1" maxEntriesLocalHeap="10000" maxEntriesLocalDisk="1000" eternal="false" diskSpoolBufferSizeMB="20" timeToIdleSeconds="300" timeToLiveSeconds="600" memoryStoreEvictionPolicy="LFU" transactionalMode="off">         
        <persistence strategy="localTempSwap" />
    </cache>

</ehcache>
