颤振 - 使用工具：overrideLibrary="io.flutter.plugins.camera"

Question

在颤振中实现相机时，我在清单文件中遇到了这个问题

    android\app\src\main\AndroidManifest.xml Error:
        uses-sdk:minSdkVersion 16 cannot be smaller than version 21 declared in library [:camera] D:\My Files\flutter-apps\login\build\camera\intermediates\merged_manifests\debug\processDebugManifest\merged\AndroidManifest.xml as the library might be using APIs not available in 16
        Suggestion: use a compatible library with a minSdk of at most 16,
                or increase this project's minSdk version to at least 21,
                or use tools:overrideLibrary="io.flutter.plugins.camera" to force usage (may lead to runtime failures)

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 21 declared in library [:camera] D:\My Files\flutter-apps\login\build\camera\intermediates\merged_manifests\debug\processDebugManifest\merged\AndroidManifest.xml as the library might be using APIs not available in 16

Answer 1

如果你想使用相机插件，你需要在你的 android build.gradle 文件中将你的 Flutter Android minSdkVersion 更新为 21：

./android/app/build.gradle

应该是这样的：

 defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.my_flutter_app"
        minSdkVersion 21
        targetSdkVersion 27
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

如果您查看plugin page，您可以看到他们也告诉您该怎么做。
