Code comparison

AndroidViewAnimations:

YoYo.with(Techniques.Tada)
    .duration(700)
    .repeat(5)
    .playOn(findViewById(R.id.edit_area));

awesome-android-ui (using a library from the collection, e.g., Material-Animations):

TransitionManager.beginDelayedTransition(container);
view.setVisibility(visible ? View.VISIBLE : View.GONE);

Summary

AndroidViewAnimations is a focused library for view animations, while awesome-android-ui is a curated list of various UI libraries and components. AndroidViewAnimations provides a simple API for applying pre-defined animations, whereas awesome-android-ui offers a wide range of UI resources that developers can choose from based on their specific needs.

The choice between these repositories depends on the project requirements. If you need a quick and easy way to add animations to your views, AndroidViewAnimations might be more suitable. However, if you're looking for a comprehensive collection of UI resources and are willing to integrate multiple libraries, awesome-android-ui provides a broader selection of options for enhancing your Android app's user interface.

Pros of Lottie-Android

• Supports complex, high-quality animations created in Adobe After Effects
• Renders animations natively on device, reducing file size and improving performance
• Extensive customization options, including dynamic property manipulation

Cons of Lottie-Android

• Steeper learning curve, especially for designers unfamiliar with After Effects
• Requires additional tools and workflow (Adobe After Effects, Bodymovin plugin)
• Potentially higher initial development time for complex animations

Code Comparison

AndroidViewAnimations:

YoYo.with(Techniques.Tada)
    .duration(700)
    .repeat(5)
    .playOn(findViewById(R.id.button));

Lottie-Android:

LottieAnimationView animationView = findViewById(R.id.animation_view);
animationView.setAnimation(R.raw.button_animation);
animationView.playAnimation();

Summary

AndroidViewAnimations offers simple, pre-defined animations with minimal setup, making it ideal for quick implementations. Lottie-Android provides more complex, customizable animations but requires additional tools and expertise. Choose based on your project's animation requirements and development resources.

Pros of ViewAnimator

• More flexible and customizable animation chaining
• Supports both View and ViewProperty animations
• Easier to create complex animation sequences

Cons of ViewAnimator

• Slightly more verbose syntax for simple animations
• Less extensive pre-built animation library

Code Comparison

ViewAnimator:

ViewAnimator
    .animate(view)
    .scale(0, 1)
    .alpha(0, 1)
    .onStart { }
    .onStop { }
    .start()

AndroidViewAnimations:

YoYo.with(Techniques.FadeIn)
    .duration(700)
    .playOn(view);

Key Differences

• ViewAnimator offers a more fluent API for chaining animations
• AndroidViewAnimations provides a larger set of pre-defined animations
• ViewAnimator supports both View and ViewProperty animations, while AndroidViewAnimations focuses on View animations

Use Cases

• ViewAnimator: Complex, custom animation sequences
• AndroidViewAnimations: Quick implementation of common animations

Community and Maintenance

• Both projects are well-maintained and have active communities
• AndroidViewAnimations has a larger user base and more stars on GitHub
• ViewAnimator has more recent updates and active development

Integration

Both libraries are easy to integrate into Android projects, with similar setup processes through Gradle dependencies.

Pros of Rebound

• More flexible and customizable spring animations
• Can be used for non-UI animations and physics simulations
• Supports both Android and iOS platforms

Cons of Rebound

• Steeper learning curve due to its lower-level API
• Requires more code to implement simple animations
• Less out-of-the-box animations compared to AndroidViewAnimations

Code Comparison

AndroidViewAnimations:

YoYo.with(Techniques.Bounce)
    .duration(700)
    .repeat(5)
    .playOn(findViewById(R.id.animation_target));

Rebound:

Spring spring = springSystem.createSpring();
spring.addListener(new SimpleSpringListener() {
    @Override
    public void onSpringUpdate(Spring spring) {
        float value = (float) spring.getCurrentValue();
        animationTarget.setScaleX(value);
        animationTarget.setScaleY(value);
    }
});
spring.setEndValue(1);

AndroidViewAnimations offers a more concise and straightforward approach for common animations, while Rebound provides greater control and flexibility at the cost of more verbose code. AndroidViewAnimations is better suited for quick, pre-defined animations, whereas Rebound excels in creating custom, physics-based animations across multiple platforms.

Pros of Material-Animations

• Focuses on Material Design animations and transitions
• Provides more complex, scene-based animations
• Includes detailed examples and explanations for each animation type

Cons of Material-Animations

• Limited to Material Design-specific animations
• Requires more setup and configuration for each animation
• Less suitable for simple, quick animations on individual views

Code Comparison

Material-Animations:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_transition);
    setupWindowAnimations();
}

AndroidViewAnimations:

YoYo.with(Techniques.Tada)
    .duration(700)
    .repeat(5)
    .playOn(findViewById(R.id.edit_area));

Material-Animations focuses on scene transitions and complex animations, requiring more setup but offering powerful Material Design-specific effects. AndroidViewAnimations provides a simpler API for quick, individual view animations with a wide variety of pre-defined effects.

Material-Animations is better suited for apps strictly following Material Design guidelines and requiring intricate transitions between screens or components. AndroidViewAnimations is more versatile for adding simple, eye-catching animations to individual views across various app styles.
