The Android Arsenal - File System

What is RXASSETMANAGER?

An RxJava2 implementation of the Android AssetManager.

Any help or contribution is welcome.

How do you GET it?

Use the jcenter() or mavenCentral() repository.

  repositories {
    jcenter()
    mavenCentral()
  }

Then pick a module.

Core

  dependencies {
    implementation "com.github.jonathanmerritt.rxassetmanager:core:x.y.z"
  }

Core-ext - includes :core automatically.

  dependencies {
    implementation "com.github.jonathanmerritt.rxassetmanager:core-ext:x.y.z"
  }

How do you USE it?

Create an instance.

val manager = RxAssetManager(context)

Then open the asset as an InputStream for the given file name/path.

Core

manager.open("file.txt").subscribe {  }

Or open as InputStreams for the given folder name/path.

Core-ext

manager.listOpen("folder").subscribe {  }

Please check the sample app for more examples.

What does it DO?

Miminally wraps the original android assetmanager into rxjava2 types.

Core - Intended to be a 1:1 copy, it's only diverted from that slighty.

TODOs

Probable

Properly setup scripts for doc and source jars. (*partially done*)
Add testing for the app and mocks for the lib. (*partially done*)
Make docs descriptive and add comments.
Use an actual versioning structure(debug, release & dev, beta, production & flavors etc...).
Put sample app on google play.
...

Possible

~~Figure out a better build configuration(maybe buildSrc and/or .kts).~~
Create an advanced fragment in the sample app, for more real examples.
Consider handling errors in the api(?).
...
