.forEach for List - org.gradle.api.GradleException: - Error: Call requires API level 24 (current min is 22): java.lang.Iterable#forEach [NewApi]

Question

我有这个代码：

private val recipes: List<Recipe>,
...
recipes.forEach {
        recyclerItems.add(RecipeBinder(it, imageLoader, onRecipeClick))
}

并且检查我有这个错误：

Caused by: org.gradle.api.GradleException: Lint found errors in the project; aborting build.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':androidclient:lintMyAppDebug'.
> Lint found errors in the project; aborting build.

  Fix the issues identified by lint, or add the following to your build script to proceed with errors:
  ...
  android {
      lintOptions {
          abortOnError false
      }
  }
  ...
  The first 3 errors (out of 18) were:

Error: Call requires API level 24 (current min is 22): java.lang.Iterable#forEach [NewApi]
          recipes.forEach {

我使用的 Kotlin 版本：1.6.10 和类路径 'com.android.tools.build:gradle:4.2.2' 如何解决？请帮助

Answer 1

尝试转换这个：

recipes.forEach {
    recyclerItems.add(RecipeBinder(it, imageLoader, onRecipeClick))
}

对此：

recipes.iterator().forEach {
    recyclerItems.add(RecipeBinder(it, imageLoader, onRecipeClick))
}

我认为仅使用 forEach，编译器认为它是来自 Java(https://developer.android.com/reference/java/util/ArrayList#forEach(java.util.function.Consumer%3C?%20super%20E%3E)) 的那个，它需要 API 24 .

（与问题无关，但我强烈建议您获取最新的 AGP 版本）

Answer 2

转到您应用的 build.gradle 级文件， 并更改 minSdkVersion 22 -> minSdkVersion 24

Answer 3

你有两个选择

1.将最低 SDK 版本设置为 24 在模块级别 build.gradle 中，在 defaultConfig 下，将 minimumSdk 设置为 21 并更改其余代码以匹配它

 defaultConfig {
    applicationId "com.somedomain.somepackage"
    **minSdkVersion 24**
    targetSdkVersion 31
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

2.Use Kotlin for in 循环

for(recipe in recipes){
recyclerItems.add(RecipeBinder(recipe, imageLoader, onRecipeClick))
}
