Fuse

Fuse is a simple generic LRU cache for Android, backed by both memory cache (LruCache) and disk-based cache (DiskLruCache) by Jake Wharton

TLDR

Here is how you might wanna use Fuse to cache your network call.

Fuse.init(cacheDir.path)

Fuse.jsonCache.get(URL("http://jsonplaceholder.typicode.com/users/1")) { result ->
    result.success { json ->
        //do something with json object (result is Result<JsonObject, Exception>)
    }
}

//if you wanna know source of cache, can be either MEM(LruCache), DISK(DiskLruCache), NOT_FOUND(newly fetched)
Fuse.stringCache.get(filesDir.resolve("json.txt")) { result, type ->
    //do something with string object (result is Result<String, Exception>)
    when (type) {
        Cache.Type.NOT_FOUND -> 
        Cache.Type.MEM -> 
        Cache.Type.DISK -> 
    }
}

Yeah, that's about it.

Dependency

• DiskLruCache

Installation

Use jitpack.io

repositories {
    maven { url "https://jipack.io" }
}

dependencies {
    compile 'com.github.kittinunf:fuse:master-SNAPSHOT'
}

How it works?

1. Fuse searches at 1st layer at LruCache (Memory), if found, delivers. If not found go to 2.
2. Fuse searches at 2nd layer at DiskLruCache (Disk), if found delivers, If not found go to 3.
3. Fuse performs fetch (by conformance with Fetcher interface), then store into LruCache and DiskCache, respectively. Subsequent uses will be much faster by going through 1 & 2.

Fuse itself, is released under MIT of course, but as Fuse depends on LruCache and DiskLruCache. Licenses on dependencies still applies.
