Lottie-android: Bug: Weird crash when showing a Lottie animation : "Invalid Layer Save Flag"

[AndroidDeveloperLB]

Tested on Pixel 2 with Android P DP3.
I tried to disable hardware acceleration. Didn't help.
Version 2.5.5 of the library, but also on 2.5.4 (updated because I was hoping it will fix it).
Doesn't seem to occur on older Android versions.
Also, file can be shown just fine via the sample Lottie app from the Play Store.
I see some logs of this sort, before the crash.

E/AbstractTracker: Can't create handler inside thread that has not called Looper.prepare()

But I can't find out where this occurs, and can't see which class cause it.

I've also noticed that another animation of Lottie also causes this crash, but another doesn't.

This is how we use it:

<...LottieAnimationViewEx
    android:layout_width="@dimen/please_wait_big__animation_size" android:layout_height="@dimen/please_wait_big__animation_size" app:lottie_autoPlay="true"
    app:lottie_loop="true" app:lottie_rawRes="@raw/please_wait_big"
    tools:src="@android:drawable/sym_def_app_icon"/>

And this is the code of the LottieAnimationViewEx class:

class LottieAnimationViewEx @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0) : LottieAnimationView(context, attrs, defStyleAttr) {

    init{
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
            useHardwareAcceleration(true)
    }

}

This is what I get in logs :

I wanted to create a new POC with this issue, and publish here, but then I got this weird error, just by adding the dependency of Lottie :

What's going on?

[AndroidDeveloperLB]

Attached the POC I wanted to make...
MyApplication7.zip

[AndroidDeveloperLB]

If needed , here's the animation file:
https://ufile.io/orxu6

[klinker24]

I started seeing this on DP3, when I updated the target SDK to 28. Not all animations crash, but the one posted above, does.

Everything still works fine on older versions of Android, with the target SDK of 28.

[AndroidDeveloperLB]

Why does it occur?
Have you reported to Google if needed?
https://issuetracker.google.com/issues

[klinker24]

I was just commenting to clarify that it happens when updating the target SDK to 28. Being on DP3 alone does not force this error. I do not know why it happens yet and do not know enough to say if it is an issue with Lottie or with Android.

Since it happens on the target SDK update, it would appear that this is a new platform restriction that will either need implemented in Lottie, or, we will need more information on how to build animations that will work with this new restriction.

[AndroidDeveloperLB]

I believe now it's the best time to investigate it, and not after Android P will become final.

[AndroidDeveloperLB]

ok reported here:
https://issuetracker.google.com/issues/110178681

[gpeal]

Fixed by https://github.com/airbnb/lottie-android/commit/8ce2bef08477279a25cf357bf7ce4d325b0aab97

[ColtonIdle]

Any chance there will be a release at some point soon that includes this? @gpeal

[vsay01]

@gpeal I used implementation 'com.airbnb.android:lottie:2.5.5' and experiences the same issue once upgrade to Android P. I would appreciate if this fix got released. Thanks

[vsay01]

@ColtonIdle Looks like there are the release v2.5.6 and v2.5.7.

I tried to add v2.5.7 but I got error that the link not resolved.

For v2.5.6, it's working fine and no more crash.

@gpeal might want to update in the wiki page the latest version since current version shown v.2.5.5 which not include this fix.

Thanks

[eric-labelle]

Yeah, 2.5.7 seemed to be broken for me too, and had nothing more than 2.5.6 so I did take 2.5.6 too to fix the problem.

[pattagobi]

its not working or me :/

[AndroidDeveloperLB]

@gpeal This was fixed and available on final release, or not?

[pattagobi]

@AndroidDeveloperLB Status: Won't Fix (Intended Behavior) this is google

[AndroidDeveloperLB]

@pattagobi So what should we do?
How was it fixed?

[GuilhE]

implementation 'com.airbnb.android:lottie:2.7.0' fixes the issue

[AndroidDeveloperLB]

@GuilhE OK thanks.

[AndroidDeveloperLB]

@GuilhE I've noticed there is a new version 2.8.0, but it causes build issues, while 2.7.0 don't. How come?
I decided to report about this here:

https://github.com/airbnb/lottie-android/issues/967

[GuilhE]

I've replied in your thread but I will leave it here as well:

I don't believe this is an error, I believe version 2.8.0 is probably using androidx while your project isn't.

https://github.com/airbnb/lottie-android/issues/967#issuecomment-426201610

[sh3r1]

Hello Good day! I am using lottie version 2.5.5 and also encountered this error, then i updated the version to 2.7.0. I would like to ask if need to migrate to androidX when using version 2.8.0?

[AndroidDeveloperLB]

@sh3r1 Please write on the issue I created. And now that I look at the changes, I think 2.8.0 does require android-X.
Well it was a matter of time till such issues would come, in one library or another...

[gpeal]

@sh3r1 Yes, 2.8.0 requires androidx.

[AndroidDeveloperLB]

@gpeal Can you please mention it on the main page of the repository? I didn't see it mentioned, and was wondering what I'm doing wrong...

[gpeal]

@AndroidDeveloperLB I added some information in the README and CHANGELOG for it.

[AndroidDeveloperLB]

@gpeal Thank you!
I suggest updating the docs too:
http://airbnb.io/lottie/android/android.html

[ollydixon]

Upgrading to 2.7.0 causes a whole load of build errors for me.private LottieAnimationView.CacheStrategy cacheStrategy; just one example.

I'm targeting build version 28.

Any ideas?

[AndroidDeveloperLB]

@voidstarfire Better ask this in a new issue...

[gpeal]

@voidstarfire The API changed in 2.7.0 and caching now happens automatically and with a LRU cache. You can remove those calls.

Details available in the changelog

[ollydixon]

They only way I could fix this way by also forcing support libs for 28

subprojects {
    afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion 28
                buildToolsVersion "28.0.3"
            }
        }
        if (project.hasProperty("dependencies")) {
            dependencies {
                implementation 'com.android.support:support-core-utils:28.0.0'
                implementation 'com.android.support:appcompat-v7:28.0.0'
            }
        }
    }
}

[nichojo89]

As for as Xamarin Android is concerned I was able to resolve this by simply upgrading to Lottie version 2.7.0!

[iamcodder]

Thanks man.I am using the 3.0.0 version and I'm getting the crash error.I change it version (2.7.0) and worked my app.

[iagormoraes]

They only way I could fix this way by also forcing support libs for 28

subprojects {
    afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion 28
                buildToolsVersion "28.0.3"
            }
        }
        if (project.hasProperty("dependencies")) {
            dependencies {
                implementation 'com.android.support:support-core-utils:28.0.0'
                implementation 'com.android.support:appcompat-v7:28.0.0'
            }
        }
    }
}

This solution for me didin't worked, still receiving error on build LottieAnimationView.CacheStrategy cacheStrategy. Tested on with lottie 2.7.0. Only android 9 crashes.

EDIT: The version 2.5.6 works with RN 59 and target SDK 28 on android 9.

[gpeal]

@iamcodder Can you attach a sample project that reproduces this?
@iagorm You'll have to post on lottie-react-native if this is a RN library issue. Otherwise, can you attach an Android sample project that reproduces this?

[gturedi]

same for s9 android9
