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

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 :

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

[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.
