Question

我创建了一个新的 Flutter 应用程序，但我第一次无法运行它。它在运行 Gradle 任务 assembleDebug 时卡住了。这是我收到的错误信息

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:stripDebugDebugSymbols'.
> NDK at C:\Users\Hp\AppData\Local\Android\sdk\ndk-bundle did not have a source.properties file

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 3m 10s
Exception: Gradle task assembleDebug failed with exit code 1
Exited (sigterm)

我已经跑了 flutter doctor，这是结果

Answer 1

对于 Android studio 4.1.1+ (gradle-plugin: 4.1.1 or above) 使用 ndkVersion

<块引用>

local.properties 中没有 ndk.dir。如果有，删除它

build.gradle（模块）

android {
  defaultConfig {
     // ...
     ndkVersion = "21.1.6352462"
  }
}

或者在您的 Android Studio 中，转到 File -> Project Structure -> SDK Location -> Under "Android NDK Location"，点击“下载”Android NDK

等待下载并重新构建项目。干杯。
