当我尝试从 Azure 中的管道启动模拟器时出现以下错误：

nohup $ANDROID_HOME/emulator/emulator -avd xamarin_android_emulator -no-snapshot > 
/dev/null 2>&1 &
$ANDROID_HOME/platform-tools/adb wait-for-device shell 'while [[ -z $(getprop 
sys.boot_completed | tr -d '\r') ]]; do sleep 1; done; input keyevent 82'

$ANDROID_HOME/platform-tools/adb devices

echo "Emulator started"

下面给出的是我的管道 yml

# Android
# Build your Android project with Gradle.
# Add steps that test, sign, and distribute the APK, save build artifacts, and more:
# https://learn.microsoft.com/azure/devops/pipelines/languages/android

#trigger:
#- feature/azure-cicd

pool:
  vmImage: 'macos-latest'

steps:

- bash: | 
    # Install AVD files
    echo "y" | $ANDROID_HOME/tools/bin/sdkmanager --install 'system-images;android-19;google_apis;x86' 
    echo "AVD system-image successfully downloaded and installed." 
  displayName: 'Download and install emulator image'
  
- bash: | 
    # Create emulator
    echo "no" | $ANDROID_HOME/tools/bin/avdmanager create avd -n xamarin_android_emulator -k 'system-images;android-19;google_apis;x86' --force

    $ANDROID_HOME/emulator/emulator -list-avds 
  displayName: 'Create emulator'

- bash: | 
    # Start emulator in background
    nohup $ANDROID_HOME/emulator/emulator -avd xamarin_android_emulator -no-snapshot > /dev/null 2>&1 &
    $ANDROID_HOME/platform-tools/adb wait-for-device shell 'while [[ -z $(getprop sys.boot_completed | tr -d '\r') ]]; do sleep 1; done; input keyevent 82'

    $ANDROID_HOME/platform-tools/adb devices

    echo "Emulator started" 
  displayName: 'Start emulator'

- bash: | 
    ./gradlew testdevelopDebug connectedMockDebugAndroidTest --stacktrace --no-daemon
    ./gradlew --stop 
  displayName: 'Run Instrumented Tests' 
  continueOnError: true

当我使用 android-28 而不是 android-19 时，这非常有效

我需要在管道中进行任何更改以启动模拟器吗？

任何帮助深表感谢

【解决方案1】：

yml 中的 adb 调用已完成以获取状态并在本地检查。在 yml 中，我试图将 while 循环传递给 adb。

此示例描述了正确的用法和解决方案：

while [ "`adb shell getprop sys.boot_completed | tr -d '
' `" != "1" ] ; do sleep 1; done
