android - Flutter .apk 已构建但未安装在设备/模拟器中

Question

我在模块级 gradle 文件中设置了自定义 outputFileName。当我尝试通过按下播放按钮(或使用 debu/release 构建的菜单命令)来运行应用程序时，apk 正在构建，但应用程序没有安装在连接的设备上。

收到以下错误。

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.

我用谷歌搜索了它的解决方案，但没有任何帮助我解决它。

下面是我的应用程序/模块级别的 Gradle 配置。

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')
}

Answer 1

尝试更换

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

使用以下代码

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

更新:
替换这个

splits {
        abi {
            universalApk true
        }
    }

与以下

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

请在 debug 中添加签名配置还。

signingConfig signingConfigs.debug
