Flutter: Gradle build failed to produce an .apk file. It's likely that this file was generated under <app_root>\build, but the tool couldn't find it

Question

I am trying to test drive an app. I keep getting a strange issue with this problem as app fail to debug/run. SDK version is 28 while the rest is below:

Flutter 1.13.9-pre.79 • channel master • https://github.com/flutter/flutter.git
Framework • revision 9eb9ea0ffa (6 hours ago) • 2020-01-13 21:30:42 -0800
Engine • revision 0235a50843
Tools • Dart 2.8.0 (build 2.8.0-dev.0.0 28c335d5a2)

Gradle build failed to produce an .apk file. It's likely that this file was generated under C:\Development\\build, but the tool couldn't find it.

Is there a way to pass this issue or a configuration that can allow me to run by providing or giving the output path to Gradle? The .apk seems to generated as the error states.

UPDATE:

Android Studio -v 3.5.3 
Gradle -v 3.4.2 
Gradle Wrapper -v 5.1.1

Solution 1

in my case I have a multi flavor app like this:

update 04/15/2021:

{
    // Use IntelliSense to learn about possible attributes.

    "version": "0.2.0",
    "configurations": [
            {
                    "name": "YOUR_PROJECT_NAME",
                    "program": "lib/main.dart",
                    "request": "launch",
                    "type": "dart",
                    "args": [
                            "--flavor",
                            "ADD_YOUR_FLAVOR_NAME_HERE" //development or staging or production
                        ]
            }
    ]

Another way:

 android {

    ...

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }

    flavorDimensions "flavor-type"

    productFlavors{
        development{
            dimension "flavor-type"
        }
        staging{
            dimension "flavor-type"
        }
        production{
            dimension "flavor-type"
        }
    }
}

So if you want to run app you have to write the flavor name and then the class name that hold main() function

flutter run --flavor staging -t lib/main_staging.dart

and I solved my error and built the .apk

Solution 2

Added the flavor name in Build name from Edit Configurations and it worked!

Solution 3

Ok, I found that it's args in launch.json if you use vscode

Solution 4

Add below code in to the app level build.gradle file after buildTypes:

flavorDimensions "flavor"

productFlavors {
    staging {
        dimension "flavor"
    }
}

And Modify your Edit Configurations like below Image :

Solution 5

After confirming the android/app/build.gradle have no issues related to flavor, please run command

flutter run --flavor dev lib/main_dev.dart 

instead of

flutter run lib/main_dev.dart --flavor dev

What version of Android Studio, Gradle Plugin for Android, and Gradle Wrapper are you using? If I remember correctly this error only happened on an older version of one of these. You should be on at least Android Studio 3.5.3, using Gradle Plugin version 3.5.3 and Gradle Wrapper version 5.4.1

[oetoni]

@Ovidiu thanks first. Now the AS version is 3.5.3 (indeed), the GP version was 3.4.2 and GW version was 5.1.1, I updated, but issue still present, I tried also a gradle clean build

[Ovidiu]

Ignore my previous comment, that's not what's causing the error. I managed to replicate it by executing 'flutter run' in a project that has configured flavors. According to your screenshot you have a flavor named 'debug', so you'd want to execute 'flutter run --flavor=debug'

[oetoni]

sorry @Ovidiu, I must disagree, I did run along a form pot in github about the flavor argument and a possibility of this causing the issue but I can assure you I have non. According to this cogitas.net/creating-flavors-of-a-flutter-app, I did checked my /android/app/build.gradle and I found non there. Maybe is there another way to check if there are flavors and I don't know off... how did you determine the fact that I have a debug flavor?

[TWL]

it looks like you've got apk file name variants, and some workarounds at github.com/flutter/flutter/issues/44796 show that you need to double check the name of the apk files.

Solved the problem for both Android and iOS. Thanks!

[Sanjayrajsinh]

should be the same build flavor name, I make a mistake that I write "stage" instead of "staging" in build flavor
