我正在尝试在我的项目中编译flac扩展以与Android Studio,ExoPlayer一起使用。我尝试按照ExoPlayer自述文件中的说明进行操作,但是出现以下错误:
cd ExoPlayer
EXOPLAYER_ROOT="$(pwd)"
FLAC_EXT_PATH="${EXOPLAYER_ROOT}/extensions/flac/src/main"
NDK_PATH="~/Downloads/android-ndk-r17c"
cd "${FLAC_EXT_PATH}/jni"
mv ~/Downloads/flac-1.3.2 flac
${NDK_PATH}/ndk-build APP_ABI=all -j4
...:~/Downloads/ExoPlayer/extensions/flac/src/main/jni$
NDK_PATH=.../Downloads/android-ndk-r17c
...:~/Downloads/ExoPlayer/extensions/flac/src/main/jni$ ${NDK_PATH}/ndk-build APP_ABI=all -j4

要获取flac扩展以在Android Studio中进行编译,我需要转到:
工具| SDKManager | SDKTools和已检查的Cmake
