A simple & fluent Android ORM, how can it be easier ? And it's compatible with RxJava2 !

Observable.fromArray(

  new Computer(Computer.WINDOWS, "MasterRace", Arrays.asList(new Software("Photoshop"))),

  new Computer(Computer.WINDOWS, "Gamerz"),

  new Computer(Computer.LINUX, "MasterRace", Arrays.asList(new Software("Gimp"))))

  .flatMap(computerDb::add)

  .subscribe();
  Observable.just(new Computer(Computer.MAC, "Mac Mini"))

  .flatMap(computerDb::add)

  .doOnNext(computer -> computer.getSoftwares().add(new Software("Photoshop")))

  .flatMap(computerDb::update)

  .subscribe();
  computerDb.select()

  .label().equalsTo("MasterRace")

  .or()

  .softwares(SoftwareDatabase.where().name().equalsTo("Photoshop"))

.asObservable()

  .subscribe(computers -> Log.d(TAG, computers.toString()));

First, initialize !

Don't forget to initialise RxAndroidOrm in your applicarion:

public class MyApplicarion extends Applicarion {

@Override public void onCreate() {

super.onCreate();

RxAndroidOrm.onCreate(this);

  
}
  
}

Second, annotate your models

Use Annotations to mark classes to be persisted:

@Model public class Computer {

@Id long id;
  String name;

List<Software> softwares; 
}

Logging

You can log all SQL queries from entities managers:

computerDb.logQueries((query, datas) -> Log.d(TAG, query) 
}

TODO

  • Enum support

Resources

Rapidly fast implementation of SharedPreferences which stores each preference in files separately, performs disk IO via NIO with memory mapped byte buffers and works IPC (between processes).

This library introduces dynamic control over vector drawables. Each and every aspect of a vector drawable can be controlled dynamically (via Java instances), using this library.

Features :

  • Control : Control every attribute related to path, group, vector and clip-path like color, alpha, strokeWdith, translation, scale, rotation etc.
  • Clip Paths : The library supports clip paths.
  • Trimming : The library allows trimming of path by using trimEnd, trimStart and trimOffset parameters.

A simple tree view with drag and drop capabilities.

A sample application showы how to realize immersive parallax effect header like Google Play app.

A custom GLSurfaceView to show image with ripple effect using OpenGL.

A powerful, flexible and easy to use Video and Image compression library for Android.

Image

It's usually said that "A picture is worth a thousand words". Images adds flair and beauty to our android apps, but we usaully have problems with these images due to thier large size. With SiliCompressor you can now compress and use your images more smoothly.

Video

Due to the high resolution of our Smartphone cameras and cameras from other devices, Video files have become large in size and thus difficult for it to be shared with others on social apps, social media and even when we need to upload it on our server. With SiliCompressor you can now compress your video file while maintaining it quality.
