Platform error occurred when running the UTP test suite
FAILURE: Build failed with an exception.
错误消息看起来像是存储问题，但模拟器应该有足够的存储空间。这就是我启动模拟器的方式：
emulator -avd S21 -memory 2048 -wipe-data -no-boot-anim -cache-size 1000 -noaudio -no-window -partition-size 8192 &
这是设备创建
avdmanager create avd --force -c 2G -k "system-images;android-32;google_apis;x86_64" -n S21
然后gradle脚本会这样调用：
./gradlew connectedDebugAndroidTest
当我手动构建通用 apk 时，通过 adb 安装它，然后 运行 仪器测试它是否正常工作。但据我了解，无需手动安装应用程序即可正常工作。
有什么问题？
我找到了解决办法。问题是模拟器启动需要很长时间，所以插桩测试失败，因为在模拟器启动时无法安装APK
Message: Failed to install APKs: UNKNOWN
我根据此处的评论改编了解决方案 Detect when Android emulator is fully booted 以延迟后续步骤，直到模拟器完全启动：
emulator -avd S21 -memory 2048 -wipe-data -no-boot-anim -cache-size 1000 -noaudio -no-window -partition-size 8192 &
adb wait-for-device shell 'while [[ -z $(getprop sys.boot_completed) ]]; do sleep 1; done;'
我想 运行 仪器测试作为我的 CI 管道的一部分，但是当我 运行 测试失败时，因为无法安装 APK（据我所知):

Platform error occurred when running the UTP test suite
FAILURE: Build failed with an exception.
错误消息看起来像是存储问题，但模拟器应该有足够的存储空间。这就是我启动模拟器的方式：
emulator -avd S21 -memory 2048 -wipe-data -no-boot-anim -cache-size 1000 -noaudio -no-window -partition-size 8192 &
这是设备创建
avdmanager create avd --force -c 2G -k "system-images;android-32;google_apis;x86_64" -n S21
然后gradle脚本会这样调用：
./gradlew connectedDebugAndroidTest
当我手动构建通用 apk 时，通过 adb 安装它，然后 运行 仪器测试它是否正常工作。但据我了解，无需手动安装应用程序即可正常工作。
有什么问题？
我找到了解决办法。问题是模拟器启动需要很长时间，所以插桩测试失败，因为在模拟器启动时无法安装APK
Message: Failed to install APKs: UNKNOWN
我根据此处的评论改编了解决方案 Detect when Android emulator is fully booted 以延迟后续步骤，直到模拟器完全启动：
emulator -avd S21 -memory 2048 -wipe-data -no-boot-anim -cache-size 1000 -noaudio -no-window -partition-size 8192 &
adb wait-for-device shell 'while [[ -z $(getprop sys.boot_completed) ]]; do sleep 1; done;'
