Flutter release app native crash, abort error [FATAL:flutter/shell/platform/android/library_loader.cc(24)] Check failed: result

Question

Below is the log of the crash:

Build fingerprint: 'google/walleye/walleye:9/PPR2.181005.003/4984323:user/release-keys' Revision: 'MP1' ABI: 'arm' pid: 17914, tid: 17914, name: yapp.mobile.app >>> myapp.mobile.app <<< signal 6 (SIGABRT), code -6 (SI_TKILL), fault addr -------- Abort message: '[FATAL:flutter/shell/platform/android/library_loader.cc(24)] Check failed: result. '

I do realize the yapp.mobile.app doesn't match my applicationId (myapp.mobile.app) and was wondering if that would cause a problem.

Also from what it looks like it could be my sqlite library which is from a flutter plugin using sflite for flutter, and not sure if the proguards I have set below will encompass that.

And I've read removing minifyEnabled true in my build.gradle could be a possible fix.

Also I don't know what that about message is trying to tell me, any help or guidance would be great.

build.gradle:

signingConfigs { release { keyAlias keystoreProperties['keyAlias'] keyPassword keystoreProperties['keyPassword'] storeFile file(keystoreProperties['storeFile']) storePassword keystoreProperties['storePassword'] } } buildTypes { release { signingConfig signingConfigs.release minifyEnabled true useProguard true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } flutter { source '../..' } dependencies { testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.1' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1' }

proguard-rules.pro:

#Flutter Wrapper -keep class io.flutter.app.** { *; } -keep class io.flutter.plugin.** { *; } -keep class io.flutter.util.** { *; } -keep class io.flutter.view.** { *; } -keep class io.flutter.** { *; } -keep class io.flutter.plugins.** { *; }

it said deleting build and nothing else so i'm not sure if it was already deleted or not, my guess it was because i never ran flutter clean before — Mfreeman

Ok i was able to get the same error by adding a debug build type in my build.gradle so it doesn't seem that flutter clean worked for that error, but when i removed minifyEnabled it does work, but i would like to keep that in order to keep my code optimized — Mfreeman

In my case it was because of an lib that wasn't flagged to keep on proguard-rules.pro, then I changed like this:

#Flutter Wrapper -keep class io.flutter.app.** { *; } -keep class io.flutter.plugin.** { *; } -keep class io.flutter.util.** { *; } -keep class io.flutter.view.** { *; } -keep class io.flutter.** { *; } -keep class io.flutter.plugins.** { *; } -keep class vn.hunghd.flutterdownloader.** { *; } -keep class com.baseflow.permissionhandler.** { *; }

As I said, in my case, you can check if it's your case, by looking at the imports, at:

/android/app/src/main/java/io/flutter/plugins/GeneratedPluginRegistrant.

My bad, in my case I have placed proguard-rules.pro file in root directory instead of app folder, may help someone.
