Release Mode Android | couldn't find "libflutter.so" #36

Hi all,

I'm having an issue when using the library and building a release apk for Android.

Reproduce issue

Create an empty flutter project
Replace main.dart with

https://pub.dartlang.org/packages/mlkit#-example-tab-

Update pubspec.yaml to

mlkit: ^0.6.2 image_picker:

run $ flutter build apk
I am getting the following

AndroidRuntime: java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/eu.my-domain.mlkit-test-VnjMxahfeCGMItX8kAUbAg==/base.apk"],nativeLibraryDirectories=[/data/app/eu.my-domain.mlkit-test-VnjMxahfeCGMItX8kAUbAg==/lib/arm64, /data/app/eu.my-domain.mlkit-test-VnjMxahfeCGMItX8kAUbAg==/base.apk!/lib/arm64-v8a, /system/lib64, /system/vendor/lib64]]] couldn't find "libflutter.so"

This seems to be linked to
flutter/flutter#18939
flutter/flutter#18494

Any ideas why this is hapenning?

Hi,

when you build apk, try the command.
flutter build apk --release --target-platform android-arm64

if you still have the same 'couldn't find "libflutter.so"' error,
your device could be 32bit.

in that case, change your android build.gradle file something like below.
build.gradle
defaultConfig {
ndk{
abiFilters "armeabi-v7a"
}
…
}

and try the command below.
flutter build apk --release --target-platform android-arm

lance-blo · 2018-09-15T08:53:07Z

Thanks. Right, as described here flutter/issues/18939, this makes the app run.

But my problem is that I will not be able to publish the app to the PlayStore as I will be targeting only one architecture.

I have tested several other plugins that are not creating the described problem.

Any ideas as to why this is happening?

azihsoyn · 2018-09-15T08:56:36Z

Hi, Thanks reporting and commenting!

I'll check it later ASAP! 😄

sayurikunugi · 2018-09-15T09:00:02Z

that's true.
my app works fine both for 64-bit and 32-bit, when using 32bit build.
how about yours?

lance-blo · 2018-09-15T09:19:48Z

Ok after several testing I have the below (my device is 64-bit).

Targeting 64-bit architecture does work.
flutter build apk --release --target-platform android-arm64

However targeting 32-bit reproduces the issue.
flutter build apk --release --target-platform android-arm

To get the 32-bit version running I need to use:
defaultConfig { ndk{ abiFilters "armeabi-v7a" } }

Albert221 · 2018-11-19T18:56:14Z

Is there any update on this?

azihsoyn · 2018-11-20T00:55:21Z

Hi, @Albert221

#36 (comment) does not resolve your issue?

RockCoder7 · 2018-12-02T13:52:47Z

This works for me! Thank you sooooooooo much!

defaultConfig { ndk{ abiFilters "armeabi-v7a" } }

hey , so first thank you , second does that mean I have to produce two different apks? or the first command is enough for the two versions ?
EDIT : arm-64 is backwards compatible , so using the abifilters and choosing only armeabi-v7a will work on all devices , unless you have an app that uses something specific to arm64 devices , then you have to make two apks , an apk for every platform, I guess you can declare this issue as solved

kelvinji2009 · 2019-01-14T04:18:37Z

@afamobius What's your minSdkVersion?

shoxter · 2019-01-19T17:08:15Z

@afamobius So is it backwards compatible without defaultConfig { ndk{ abiFilters "armeabi-v7a" } } or you needed that for it to be backwards compatible?

dhaval0122 · 2019-06-20T14:36:25Z

any solution? i have upgrade flutter to 1.7.4 still app crash while open.

nimesh1997 · 2019-06-22T09:47:41Z

After Upgraded flutter to 1.7.4 new error comes how to resolve this in flutter version?

amreniouinnovent · 2019-09-02T04:27:37Z

this works for me
defaultConfig {
ndk {
abiFilters 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'mips', 'mips64', 'arm64-v8a'
}
}

marvinsxtr · 2019-10-01T01:00:49Z

After none of the solutions above worked for me, i looked into the documentation and found that it worked fine when i ran
flutter build apk --split-per-abi
and picked the release-apk corresponding to my system architecture.

Same..

this works for me
defaultConfig {
ndk {
abiFilters 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'mips', 'mips64', 'arm64-v8a'
}
}

do you run build appbundle or apk or splitapk
?

kw2019ltd · 2020-03-28T04:28:38Z

We need fix from the flutter team

Hello. Trying to build flutter app for x86 32 bit, but libflutter.so is not generated.
How can i fix this?

armv7, arm46 and x86_64 are generated without issues

devDeejay · 2020-05-07T12:14:36Z

Any fixes guys :( ?

z85510 · 2020-06-11T20:51:45Z

I have the same problem.
I've tried to add

ndk{
abiFilters "armeabi-v7a"
}

but after adding this line in build.gradle then my app doesn't work on x86 emulators.

premtemp1 · 2020-06-18T12:57:52Z

Getting the same error as @emadd ..
any solution
this my filter setting --
abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64'

rlecheta · 2020-07-14T12:11:15Z

I'm integrating flutter in some existing app and I have the same error
/base.apk!/lib/x86_64, /system/lib64]]] couldn't find "libflutter.so"
at java.lang.Runtime.loadLibrary0(Runtime.java:1012)
at java.lang.System.loadLibrary(System.java:1669)
And this doesn't solve the problem:
ndk {
abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86_64'
}
I can build a release apk, but I can't run it on emulador using Android Studio.

uzumaki258 · 2020-09-09T07:02:03Z

I have the same issue with Android 5.1 and 5.1.1:
nativeLibraryDirectories=[/vendor/lib, /system/lib]]] couldn't find "libflutter.so"
I have used it.
buildTypes {
release {
// other configs
ndk {
abiFilters 'armeabi-v7a','arm64-v8a','x86_64'
}
signingConfig signingConfigs.release
}

Same here, tested all configurations proposed. 2 years and still open.
