android - ROLI JUCE Android CMake 错误，生成的空白演示应用程序无法在 Android Studio 中编译

Question

下载 Projucer 后我生成了一个空白应用程序，我将它导出到 Android(在 Debug模式下)并在 Android studio 中打开它。修复与 SDK 和 NDK 版本有关的错误后(我更新了引用以使用最新版本构建)，代码无法在 CMake 阶段构建，并显示以下错误输出:

我曾尝试重新安装 Projucer、运行不同版本的 Android Studio 并生成不同的演示项目，但它们都在同一点失败。在同一台计算机 (macOS) 上生成 Xcode 文件并下载相同的 Projucer 时，代码会在模拟的 iOS 上编译和运行。

我是否遗漏了某些库或某个地方的文件路径不正确？

引发错误的文件来自他们自己的库，所以我不确定是什么导致了这个问题，我们将不胜感激!

错误特别发生在 USE_FUCNTION(glDrawBuffer ...) 行，因为我尝试在库文件中移动这行代码并且错误随之移动(它在代码块的末尾所以我想看看是不是那个代码块失败了，但它似乎特别是那一行)

Answer 1

将 Android 导出器中的“最低 SDK 版本”设置为 24 之类的值，而不是默认值 10。

当前的默认值有点低，在下一个 JUCE 版本中将提高到 28。
