Hey! Just want to say first that I really appreciate your work.

I'm using this library in an application and found a bug when using proguard. Without any changes to the proguard.project.txt file, I get this error when trying to use the animations:

W/System.err(22899): java.lang.NoSuchMethodException: <init> [float]
W/System.err(22899):    at java.lang.Class.getConstructorOrMethod(Class.java:472)
W/System.err(22899):    at java.lang.Class.getConstructor(Class.java:446)
W/System.err(22899):    at com.daimajia.easing.Skill.a(SourceFile:104)
W/System.err(22899):    at com.daimajia.easing.Glider.a(SourceFile:33)

I worked around this by adding to my proguard-project.txt file:

-keep class com.daimajia.easing.** { *; }
-keep interface com.daimajia.easing.** { *; }

It might be helpful to add this to documentation (like the README).

Remove android:icon & android:label so there won't be issue on merging manifests.

All resources should be namespaced. And maybe default generated resources should not be included in released builds This will cause aapt duplicate file errors if imported into a project that has a default generated ic_launcher file in a drawable-hdpi directory.

Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'.

It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html

I modified readme.md for this change

Multiplying the 's' member of the class by 1.525 every time calculate was called was causing the method to be unusable. Simply removing that multiplication gives the result I would expect, and makes the code resemble the BackEaseIn and BackEaseOut methods more closely.

PropertyAnimation文档里似乎更推荐通过自定义Interpolator来控制所选属性的变化率。而TypeEvaluator的描述是：If you want to animate a type that is _unknown_ to the Android system, you can create your own evaluator by implementing the TypeEvaluator interface，似乎更加强调针对自定义类型或属性改变的情况。 自己在项目中几乎都使用Interpolator，这里不太明白，请教一下。 Thank you!:)

According this issue we want to migrate daimajia/AndroidViewAnimations to AndroidX.

Since daimajia/AndroidViewAnimations depends on this project, migrate this project to AndroidX first should be better.

Actually this project can support AndroidX without migration, but we should also keep this project up to date.

So we remove unused and outdated dependency appcompat-v7, and upgrade targetSdkVersion to 29.

GitHub changed the way Markdown headings are parsed, so this change fixes it.

See bryant1410/readmesfix for more information.

Hi, I want to know how to concatenate animations, I mean:

For example:

1. I have two list of animations. Each list contain animations to play together. 2.I want to execute secuencially, first the list one (play together) and then execute the list two (play together).

I'm trying to execute this situation using listeners, but I don't know why doesn't work. This is my code:

    final Point distance = new Point(Math.abs(pointPlane.distace(pointImage1).getX()), Math.abs(pointPlane.distace(pointImage1).getY()));
    AnimatorSet set = new AnimatorSet();
    set.playTogether(
            Glider.glide(Skill.Linear, 700, ObjectAnimator.ofFloat(imagePlane, "translationY", 0, -1 * distance.getY())),
            Glider.glide(Skill.Linear, 700, ObjectAnimator.ofFloat(imagePlane, "translationX", 0, distance.getX()))
    );
    set.setDuration(2000);
    set.start();
    set.addListener(new Animator.AnimatorListener() {
        @Override
        public void onAnimationStart(Animator animator) {}

        @Override
        public void onAnimationEnd(Animator animator) {
            imagePlane.setX(pointImage1.getX());
            imagePlane.setY(pointImage1.getY());
            final Point distance = new Point(Math.abs(pointPlane.distace(pointImage2).getX()), Math.abs(pointPlane.distace(pointImage2).getY()));
            AnimatorSet set2 = new AnimatorSet();
            set2.playTogether(
                    Glider.glide(Skill.Linear, 700, ObjectAnimator.ofFloat(imagePlane, "translationY", 0, 30)),
                    Glider.glide(Skill.Linear, 700, ObjectAnimator.ofFloat(imagePlane, "translationX", 0, 30))
            );
            set2.setDuration(2000);
            set2.start();
        }

        @Override
        public void onAnimationCancel(Animator animator) {}

        @Override
        public void onAnimationRepeat(Animator animator) {}
    });

Thanks in advance!

}

Is it possible to add custom skills in my project by including the lib (without the need to clone the project and add it in the source code)?

Thanks in advance.

Hi AnimationEasingFunctions, Thanks so much because your lib very great! Sorry becase my english very bad! I try to start animtorset via method playTogether But i have problem about move back View to old position! How can i do that? Please help me! Hope nice day to you guys
