Expected result: The app to start from scratch as it was killed by the system and i am not saving native state

Actual result: The app tries to open and then crashes within a second . It works fine on subsequent launches until this issue occurs again.
This only occurs on release builds and not debug builds . Debug builds give the expected result

ercadev · 2019-12-28T08:56:34Z

I have the same issue. Are you sure it has to do with out of memory? I have not digged too deep in the problem yet and thought it had to do with my pageview where i keep the state alive on page change

kriticalflare · 2019-12-28T12:53:09Z

@ercadev I verified that it was due to OOM by going through logcat and finding that crash occurred only when the system killed the app in background. You can also try and verify this. The system does log which app is being killed

ercadev · 2019-12-28T13:04:18Z

@ercadev I verified that it was due to OOM by going through logcat and finding that crash occurred only when the system killed the app in background. You can also try and verify this. The system does log which app is being killed

But is that expected? That app gets killed if for example you have to many apps open? Have you solved the provlem yet?

Its expected for the app to get killed in oom conditions. And since flutter doesn't provide the same native state restoration as native platforms , you expect the app to start from scratch after getting killed. But in this case its crashing.

Open App > Killed by OOM > Crashed when opening from recents/Multi tasking > Opens fine now

Have you solved the problem yet?

Nope. Maybe its some proguard/r8 like issue caused due to minification in release builds but I don't have the skill to debug this

ercadev · 2019-12-28T17:27:10Z

Okay I understand. I don't have the skill either. Hope someone with knowledge can answer. I'm going to try some things and will come back to you if I find something.

ercadev · 2019-12-29T09:27:07Z

So my problem seems to been gone now. I don't get these crashes anymore and the only thing i did was to follow the step "Enabling Proguard" here

kazume · 2019-12-29T10:27:23Z

I have proguard configured but am also experiencing those crashes :-/

kriticalflare · 2019-12-29T11:32:37Z

@ercadev My suspicion about this being a proguard issue turned out to be right . I too enabled proguard and i can confirm that the crash is fixed now.

@kazume maybe you have proguard not configured properly or you dont have the correct rules for any plugin that you maybe using.

kazume · 2019-12-29T11:44:57Z

So my problem seems to been gone now. I don't get these crashes anymore and the only thing i did was to follow the step "Enabling Proguard" here

I followed exactly these steps to enable proguard (admittedly the first time I've set it up).

kriticalflare · 2019-12-29T12:56:38Z

@kazume can't say much without see what you did exactly. Share the repo if you can

kazume · 2019-12-29T13:14:02Z

@kazume can't say much without see what you did exactly. Share the repo if you can

https://bitbucket.org/kazume/frosty

kriticalflare · 2019-12-29T13:30:11Z

@kazume you seem to be missing a proguard rules file. Also you seem to be using a lot of plugins that might need extra proguard rules maybe

kazume · 2019-12-29T13:34:25Z

puh ok, thx for the review ... I'll look into that :)

kazume · 2019-12-31T11:14:41Z

@kazume you seem to be missing a proguard rules file. Also you seem to be using a lot of plugins that might need extra proguard rules maybe

Thx again for the hint. I created the proguard-rules file but it was at the wrong location :) now the crash is history for me as well.

kriticalflare · 2020-01-16T15:41:39Z

Flutter docs now recommend using R8 alone , and all references of proguard have been removed. But the crash still occurs in release when proguard isnt used.
https://flutter.dev/docs/deployment/android#r8

flutter/flutter#47635

themisir · 2020-01-17T12:44:36Z

Is there any solution for latest stable version of flutter? I did not enabled proguard or disabled R8.

kriticalflare · 2020-01-19T05:10:47Z

@themisir for now you will need to enable proguard on release builds. You can see the commit i referenced this issue for reference

Cphilo · 2020-01-21T09:54:17Z

This issue help me a lot.

armadilov · 2020-01-22T10:07:12Z

I still see this issue using Stable Channel - v1.12.13+hotfix.5.

Hint: To easily test/reproduce - allow only 1 background process on your android device (via developer options), so when you switch between apps, it needs to recreate from scratch.

Fix: Enable proguard on your release builds. I used these instructions:
https://medium.com/@swav.kulinski/flutter-and-android-obfuscation-8768ac544421

Ajmal-Jalal · 2020-01-31T05:56:05Z

This happens for me as well, couldn't fix it yet.

bedryck · 2020-02-01T13:08:22Z

I have the same issue when clearing ram and resume the app.

pascalw · 2020-03-03T06:34:49Z

@matthew-carroll thanks that would be great!

Easiest way to reproduce seems to be this:

Generate a new empty app on Flutter stable (Flutter 1.12.13+hotfix.8) (flutter create flutter_crash_on_resume)
Build a release apk (flutter build apk --release --target-platform android-arm64) and install it
Open the app and put it in the background
Kill the app using ADB adb shell am kill com.example.flutter_crash_on_resume
Try to launch it -> crash. Launch it again and it will start properly.

If you instead build the app with flutter build apk --release --target-platform android-arm64 --no-shrink and repeat the same steps, the app will not crash after kill.

Edit: Updated with ADB command to simulate OOM kill.

orestesgaolin · 2020-03-03T08:04:55Z

I can confirm that @pascalw's steps reproduce the issue on my side. I can privately share access to the project that has this exact issue @matthew-carroll.

matthew-carroll · 2020-03-03T21:37:20Z

Thanks @pascalw and @orestesgaolin

With @pascalw's reproduction steps I have repro'd the crash. I'm investigating now.

matthew-carroll · 2020-03-03T23:37:40Z

I added a @Keep annotation on the custom state object and that appears to have resolved the issue on my end. I have a PR up here:
flutter/engine#16916

It would be great if someone who is comfortable with local engine compilation could give that PR a try to verify what I found locally.

pascalw · 2020-03-04T19:35:12Z

@matthew-carroll thanks for the fix! I tried compiling the engine locally but my computer doesn't have enough resources 🙈

Now that your PR is merged, is there a way to verify it via the master channel?

matthew-carroll · 2020-03-04T20:11:59Z

The only option to verify it is still to compile the engine locally. You'll need to wait for an engine roll into the framework to be able to verify this on the master framework branch.

goderbauer · 2020-03-04T22:44:19Z

Closing since we believe this got fixed with flutter/engine#16916. Please re-open if this is not correct.

huextrat · 2020-03-05T08:27:56Z

Will the engine update be effective on Flutter Stable branch too?

tvolkert · 2020-03-05T16:49:35Z

This fix is on master and in the dev channel at versions v1.15.8 and above. It's not going to be cherrypicked onto stable, but it will be part of the next stable release.

pascalw · 2020-03-05T20:32:32Z

Thanks! I can confirm it's fixed if I build my APK using master 👍

canewsin · 2020-03-07T19:10:46Z

@tvolkert when can we expect next stable release ? Because I do face that issue on my new app, which is already has crashes on Android 9.0.
Edit : it's happening on all versions 😢

tvolkert · 2020-03-08T00:06:54Z

@canewsin we're working to push this to beta next week (in the next few days). The next stable is 4-6 weeks away.

canewsin · 2020-03-08T02:41:59Z

@matthew-carroll instead of switching to master or dev repo of flutter, can we put a proguard rule in our project, to keep class ?

Could you give me the proguard rule !

canewsin · 2020-03-08T09:29:52Z

Currently I was using --no-shrink option hope it will solve the error.

ercadev · 2020-03-08T09:31:55Z

@canewsin Here is the old documentation how to enable proguard. Works perfectly for me.
https://web.archive.org/web/20191016174553/https://flutter.dev/docs/deployment/android#enabling-proguard

canewsin · 2020-03-08T09:46:15Z

@ercadev I know how to use proguard, but my issue is, I use many libraries, so if I forgot to add any rule to it, which is required by library, then it will break another part of app. So, instead I opt for --no-shrink option.

AmruthPillai · 2020-03-08T13:44:34Z

I released my app today, which was built on the stable build, but few users are getting this issue. Don't know what the cause of the problem is, it's a very specific and small subset of users facing this problem, but it has caused users to rate the app with 1 star :(

What can I do to build the app without this error?

matthew-carroll · 2020-03-08T18:38:39Z

@blasten we're on R8 now, right? Do you know if there is a rule that devs can add to solve this problem locally until the next stable Flutter release?

blasten · 2020-03-09T21:49:54Z

While waiting for the next stable release, it's possible to add a proguard rule. Check this article.

In <your-app-directory>/android/app/proguard-rules.pro, add this line:

-keep public class io.flutter.embedding.android.FlutterSplashView.$SavedState { *; }

…s are getting See flutter/flutter#47635

oom- · 2020-04-02T20:42:20Z

Any news regarding this point ? I have exactly same situation with the last verstion:

Flutter 1.12.13+hotfix.9 • channel stable • https://github.com/flutter/flutter.git

Engine • revision af51afceb8

I will setup proguard waiting for stable.
