Flutter:Gradle 构建未能生成 .apk 文件.这个文件很可能是在<app_root>\build下生成的,但是工具找不到 [英] 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
问题描述
我正在尝试试驾一个应用.由于应用程序无法调试/运行,我一直遇到这个问题的奇怪问题.SDK 版本为 28,其余版本如下:
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 构建未能生成 .apk 文件.这很可能文件是在 C:\Development\\build 下生成的,但是工具找不到.
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.
有没有办法通过提供或将输出路径提供给 Gradle 来传递这个问题或允许我运行的配置?.apk 似乎是在错误状态下生成的.
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.
更新:
Android Studio -v 3.5.3
Gradle -v 3.4.2
Gradle Wrapper -v 5.1.1
推荐答案
就我而言,我有一个像这样的多口味应用:
in my case I have a multi flavor app like this:
2021 年 4 月 15 日更新:
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing 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
]
}
]
另一种方式:
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"
}
}
}
因此,如果您想运行应用程序,您必须编写风味名称,然后编写包含 main() 函数的类名
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
我解决了我的错误并构建了 .apk
and I solved my error and built the .apk
