【问题描述】：
当我尝试在本地或 AppCenter 上构建我的 Flutter 项目的 Android 版本时，我收到此错误，它找不到自己构建的 APK！ ：
...
[ ] BUILD SUCCESSFUL in 3m 51s
[ ] 904 actionable tasks: 903 executed, 1 up-to-date
[ +711 ms] Running Gradle task 'assembleRelease'... (completed in 232.8s, longer than expected)
[ +15 ms] "flutter apk" took 260,152ms.
Gradle build failed to produce an .apk file. It's likely that this file was generated under /Users/runner/runners/2.163.1/work/1/s/build, but the tool couldn't find it.

【解决方案1】：
你应该检查你的 appcenter-post-clone.sh 它应该是这样的
#!/usr/bin/env bash
#Place this script in project/android/app/
cd ..
# fail if any command fails
set -e
# debug log
set -x
cd ..
git clone -b beta https://github.com/flutter/flutter.git
export PATH=`pwd`/flutter/bin:$PATH
flutter channel stable
flutter doctor
echo "Installed flutter to `pwd`/flutter"
# build APK
flutter build apk --release
# if you need build bundle (AAB) in addition to your APK, uncomment line below and last line of this script.
#flutter build appbundle
# copy the APK where AppCenter will find it
mkdir -p android/app/build/outputs/apk/; mv build/app/outputs/apk/release/app-release.apk $_
# copy the AAB where AppCenter will find it
mkdir -p android/app/build/outputs/bundle/; mv build/app/outputs/bundle/release/app-release.aab $_
