android-advancedrecyclerview: AnimatorCompatHelper Class Not Found Exception using AppCompat 26.0.0

Hi, guys. Sorry for the inconvenience 🙇

I am going to start working for the new support libraries v26.0.0. Hopefully, I can manage all features work well with the new libraries soon…

I’ve just pushed a new branch which bumps support libraries to v26. I am now working on this branch and its still a pre-stable version.

• feature/support_libraries_v26

---

If you want to try it out now, please add the following jitpack configuration to build.gradle.

repositories {
    maven { url "https://jitpack.io" }
}
dependencies {
    compile 'com.github.h6ah4i:android-advancedrecyclerview:feature~support_libraries_v26-SNAPSHOT'
}

@FredDev06 @SUKI-Huang I’m using develop branch as workaround:

compile 'com.github.h6ah4i:android-advancedrecyclerview:develop-SNAPSHOT'

Any updates on this? Android O just got officially released by the way yesterday, which means we’re still waiting for an official fix on the main branch.

@svenoaks, @devjta, @SUKI-Huang, @tdtran, @AXwjg, @fdonzello

Hi all, sorry for the very late response 🙇

I have just released v0.11.0 today and it includes the fix of this issue, so I am going to close this issue within a few days.

Creating the AnimatorCompatHelper class seems to work but not sure if totally safe. compile ‘com.github.h6ah4i:android-advancedrecyclerview:develop-SNAPSHOT’ has weird animation when item is dragged to new position that wasn’t present in older. https://github.com/h6ah4i/android-advancedrecyclerview/issues/425

I am afraid that this might be a regression of the latest release.

I hope this issue would be solved by implementing the new onItemDragStarted() / onItemDragFinished() methods. Please read the following migration guide for more detials. (If you still see the issue with v0.11.0 , please create a new issue report.) Thanks.

This solution worked for me: https://stackoverflow.com/questions/43320496/noclassdeffounderror-android-support-v4-animation-animatorcompathelper

Added to the bottom of the build.gradle (Module:app):

configurations.all { resolutionStrategy.eachDependency { DependencyResolveDetails details -> def requested = details.requested if (requested.group == ‘com.android.support’) { if (!requested.name.startsWith(“multidex”)) { details.useVersion ‘25.4.0’ } } } }

I am about to publish my app in which I used this library. So, I would like to know whether I should wait for its stable release or pre-stable version (feature~support_libraries_v26-SNAPSHOT) is also fine.

@h6ah4i tried it, and still crashing

and yes, I have cleaned and reinstalled,

EDIT

Solved with

compile 'com.github.h6ah4i:android-advancedrecyclerview:feature~support_libraries_v26-SNAPSHOT'

I made a pull request with a temporally fix using appcompat 25.3.1

He’s alive!!! Thanks man.

Yeah, was barking at the wrong tree 😄 Found the error/cultrip for it…

But if you have to wait for external programs + HAVE to use the Android 8.0/Oreo SDK, just create the class with the HoneyCombImplementation:

Create class: android.support.v4.animation.AnimatorCompatHelper

public class AnimatorCompatHelper { private static TimeInterpolator mDefaultInterpolator; public static void clearInterpolator(View view){ if(view != null){ if (mDefaultInterpolator == null) { mDefaultInterpolator = new ValueAnimator().getInterpolator(); } view.animate().setInterpolator(mDefaultInterpolator); } } }

Has this issue of NoClassDefFoundError been fixed?

Same here! The snapshot version with support library 26 does not seem to be available anymore. 😕

compile 'com.github.h6ah4i:android-advancedrecyclerview:feature~support_libraries_v26-SNAPSHOT'

does not available now ? I got an error this morning

Error:Could not find com.github.h6ah4i:android-advancedrecyclerview:feature~support_libraries_v26-SNAPSHOT.
