我不能再运行 Flutter 项目了

Question

昨天我最后一次在我的 Flutter 项目上工作。今天我只启动了 Android Studio 并尝试启动我的项目，我收到了一条错误消息。我尝试了一切，我还检查了是否有一些更新等。

我能做些什么来解决这个问题？

这是错误信息：

Answer 1

minSdkVersion 16 cannot be smaller than version 23

您使用的其中一个插件 (xyz.luan.audioplayers) 与 API23 以下的 android 版本不兼容。您需要将项目的最低 SDK 版本设置为 23 或更高版本。

转到项目中的android 文件夹并打开app 文件夹，然后打开build.gradle 文件。

在该文件中，在defaultConfig 下编辑以下行

minSdkVersion 23

Answer 2

您需要仔细阅读official document。如前所述，使用<uses-sdk tools:overrideLibrary="xyz.luan.audioplayers"/> 配置您的build.gradle 文件。

Gradle 构建失败

为了支持 playBytes 方法，这对使用 API >= 23 功能有硬性要求，并且您的构建可能会失败，具体取决于您的最低 sdk 目标。要覆盖它，您需要将 添加到您的 build.gradle
