I have set a custom outputFileName in the module level gradle file. When I try to run the application by pressing the play button (or using menu commands for debu/release build), the apk is getting built but the application is not getting installed on the connected device.

Getting the following error.

Finished with error: Gradle build failed to produce an .apk file. It's likely that this file was generated under C:\Users\BnayA\Work\Office\sangrahapp\build, but the tool couldn't find it.

I googled the solution for it, but nothing helped me to fix it.

Below is my app/module level Gradle config.

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

ant.condition(property: 'os', value: 'windows') {
    os(family: 'windows')
}
ant.condition(property: 'os', value: 'unix') {
    os(family: 'unix')
}

                case 'windows':

            standardOutput = stdout

Try to replace 

outputFileName = new File(outputFileName.replace(".apk", "-${defaultConfig.versionName}.apk"))

with the following code

 outputFileName = new File(
             output.outputFile.parent,
             outputFileName.replace(".apk", "-${defaultConfig.versionName}.apk"))

Update: replace this

splits {
        abi {
            universalApk true
        }
    }

with the following

splits {
        abi {
            enable true
            reset()
            universalApk false
        }
    }

Please add signing config in debug also.

signingConfig signingConfigs.debug
