Load too many json files --> Out Of Memory

[tuanhs0606]

Dear,

Currently I am facing the following problem: I have about 30 json files, and currently if I need to display all 30 json files I need 30 LottieAnimationView to display 30 json files and use setRepeatCount(LottieDrawable.INFINITE). This leads to Out Of Memory problem With this case could you suggest me how to solve Out Of Memory problem or is there a way to use 30 json files displayed on 1 LottieAnimationView?

Reguards, Thank you so much!

Can you do some profiling to determine what is using the memory? Do you have bitmaps in your animations? Lottie itself doesn't use very much memory.

1. Do you have bitmaps in your animations ==> yes
2. please help me check one in them(json file) https://drive.google.com/file/d/1FFVOuew9Ryv4_TnTPJ0Wviqpynb8hamF/view?usp=sharing

@tuanhs0606 I don't have time to look at your animation right now but, most likely, this has less to do with Lottie and more to do with bitmaps. I'd recommend using the Android Studio memory profiler to see where the memory is being used.

1. I'd recommend using the Android Studio memory profiler to see where the memory is being used.

==> i just check Android Studio memory profiler, when i use lines code following but memory doesn't decrease

                animationViewEffect.pauseAnimation();
                animationViewEffect.cancelAnimation();
                animationViewEffect.clearAnimation();
                animationViewEffect.removeAllAnimatorListeners();
                animationViewEffect.removeAllUpdateListeners();
               LottieCompositionFactory.clearCache(application);

==> How to clear/decrease this?

2. Please check log cat when happen Out Of memory: java.lang.OutOfMemoryError at android.graphics.Bitmap.nativeCreate(Native Method) at android.graphics.Bitmap.createBitmap(Bitmap.java:1095) at android.graphics.Bitmap.createBitmap(Bitmap.java:1041) at android.graphics.Bitmap.createBitmap(Bitmap.java:991) at android.graphics.Bitmap.createBitmap(Bitmap.java:952) at com.airbnb.lottie.LottieDrawable.ensureSoftwareRenderingBitmap(LottieDrawable.java:1533) at com.airbnb.lottie.LottieDrawable.renderAndDrawAsBitmap(LottieDrawable.java:1486) at com.airbnb.lottie.LottieDrawable.draw(LottieDrawable.java:525) at android.widget.ImageView.onDraw(ImageView.java:1360) at android.view.View.draw(View.java:21868) at android.view.View.updateDisplayListIfDirty(View.java:20741)

Can you set the render mode to hardware?

[tuanhs0606]

@gpeal Sorry I haven't been able to go online and reply to you for the past few days

Can you set the render mode to hardware? ==> Yes, I also tried with this setting but it still happen OOM problem animationView.setRenderMode(RenderMode.HARDWARE);

Please check the json file with more size than I am using(About 14Mb): https://drive.google.com/file/d/1XhUESPey7IjGq5xfTF59ofpZaPvJ81nb/view?usp=sharing

. Thank you!

@gpeal Could you help me about my problem above?

[gpeal]

@tuanhs0606 Because I work on Lottie on nights and weekends and I'm the sole maintainer, I prioritize requests from sponsors. For a request like this, I have a queue of Lottie work that I get through and will only get to this once it bubbles up to the top.

@tuanhs0606 Can you share the preview of screen that you are trying to build using layout inspector. I think this issue maybe due to not using recyclerview or not using recyclerview properly (recyclerview with wrap content inside nested scrollview)

[gpeal]

I fixed a likely unrelated bug I discovered while taking a look at your animation. However, you have 181 720p bitmaps in your animation. Lottie is meant to be a vector renderer. If you're going to load effectively png sequences, you're likely better off with something else.

[tuanhs0606]

@gpeal Thanks for your support. I check memory in app by use Profiler tool. I see the following:

• use clear cache but not work: LottieCompositionFactory.clearCache();

• But using these lines of code it can see clear memory:

  animationViewEffect.setCacheComposition(true); animationViewEffect.setRenderMode(RenderMode.SOFTWARE); animationViewEffect.enableMergePathsForKitKatAndAbove(true); animationViewEffect.setRepeatCount(LottieDrawable.INFINITE); animationViewEffect.setAnimationFromJson(lottieJsonEffect, pathLottieJson); (Not set play for animationViewEffect)

Can you help me explain?

[gpeal]

None of those will help you as long as you are rendering your animation because your animation itself loads like 600mb of bitmaps.

[tuanhs0606]

@gpeal Thank you. Could you help me suggest me any other way show like lottie view and set background color to transparent?

I have same issue, native bitmap memory 200MB, I use reflect call LottieImageAsset bitmap recycle or After the animation ends, directly set a new empty resource lottieAnimView.setAnimation(R.raw.empty) "{}"

[OhPeterPan]

我有同样的问题，本机位图内存 200MB，我使用反射调用 LottieImageAsset 位图回收 或 动画结束后直接设置一个新的空资源 lottieAnimView.setAnimation(R.raw.empty)

What is the Empty file format? I created a.json file, but it directly triggered the crash
