How to replace SwipeRefreshLayout loading animation with a Lottie animation

I'm trying to replace SwipeRefreshLayout loading animation with a Lottie animation
I have gone through all the libraries listed in android arsenal, none of them is feasible for my requirement as they do not implement Lottie animation and all the libraries have pre-coded animation
I have also tried this library which says "LottieSwipeRefreshLayout" from Github. but it is not working, as the animation is not visible, I do not want to use a library for such a small concept please suggest me the best way to implement.
Help me like this very much important for my task

"LottieSwipeRefreshLayout" worked out for me. the main catch is to use attribute app:layout_type="content" in your recyclerview,scroll view, nested scroll view etc.
Also to customize the Lottie animation modification can be done in listeners onTriggerListener and onProgressListener which are overridden in LottiePullToRefreshLayout class

Custom animation transition for Android

I have started working on the app and I would like to add some nice animation. I have seen some transitions where it has fade in effects, left to right ect.
But can anyone tell me what should I use or where to start to develop animations like this?

It's Shared or Scene animation in which you can share component from one activity to another activity or fragment to fragment
here is official docs and simple example

You can also use these links. It may be help you.

How to create flip animation in android?

I have a tablelayout with multiple viewFlipper in each square. What I want is whichever viewflipper i touch, the view should flip. Everything is working fine but what I need is this kind of animation.
The animator files given there cannot be used in viewFlipper.setInAnimation(this, android.R.anim.fade_in);. We need to use anim for it not animator.
Android do give some built in animations but all of them are fade, slide etc but not flip. I think flipping is one of the most used animations, why isn't android providing one in default or am I missing something ?

You can try github library - Flip 3D View.

Finally I was able to solve this. Although there is a library but you need not used the whole library just for flipping views. check out this tutorial. Basically you create an animator xml as shown in the android guide in question. Then you can use it to animate any object not only views. Just use it like this
Animator flipAnimator = AnimatorInflater.loadAnimator(this,R.animator.card_flip_left_in);
flipAnimator.setTarget(cardView);
flipAnimator.start();

Use transition methods in Transitions-Everywhere library

I'm using TransitionsEverywhere library https://github.com/andkulikov/Transitions-Everywhere and I'm wondering if is it possible to use methods setSharedElementEnterTransition or setEnterTransition using TransitionInflater from this library? Or is there another solution to use smooth and pretty transition between two fragments on Android 4?

It is not possible in Transitions-Everywhere library. You can check this issue on github account :
https://github.com/andkulikov/transitions-everywhere/issues/11
I didn't try but this library seems like doing fragment transitions on pre-lollipop devices :

Changing animation style of ViewPager

I want to change the animation style of Android's ViewPager class with using Android Animation Framework. Is it possible?

See my answer at: Slowing speed of Viewpager controller in android, might be helpful.
You can further customize the Scroller class to change the Interpolator to something more extreme.

You can use new android-support-v4.jar to do it.
Please reference the following official web page: Customize the Animation with PageTransformer
http://developer.android.com/training/animation/screen-slide.html

Maybe this post can be helpful if you are looking for a different animation. This animation did not use android's native pager. There are some issues that should be solved but at all i think it is helpful

Look at the example here
http://code.google.com/p/maniana/source/browse/#git%2FManiana%2Fsrc%2Fandroid%2Fsupport%2Fv4%2Fview
Search ViewPager.java for mForcedScrollDurationMillis. It's a hack to control the smooth scroll speed.
It also require to remove ViewPager and its internal classes from the original jar

Something other than slide may be more involved.
