我正在嘗試使用Android Studio 2.3構建NDK項目，NDK與它集成在一起，Gradle 3.3中，我使用了一些共享庫（它與NDK一起提供，設備），以及這些共享庫在上市的CMakeLists.txt做「清潔工程」搖籃成功不誤，編譯NDK項目時Android Studio中的鏈接器錯誤
8:36 PM Gradle sync started

但上運行它給出了一個鏈接錯誤的項目。

從錯誤中，好像工具鏈不能鏈接到libaaudio，但我用1頭文件在我的代碼從這個未來是.so這樣
#include <aaudio/AAudio.h>
也NDK是正確的向我展示這個模塊的所有可用選項，所以我不認爲這個.so與項目沒有關聯。只是爲了確認更多的libaaudio已經存在於這些路徑中（這個lib帶有NDK包）

你是在編譯代碼的時候，你需要下載代碼（從android studio IDE或https://github.com/googlesamples/android-audio-high-performance？它被設置爲使用android-26和clang 。你可以試試去你下載的目錄，然後rm -fr your-dir/app/.externalNativeBuild，你的app/app/build？如果它仍然發生，那是一個bug，將會看到它。thx – Gerry
我有將minSdkVersion設置爲24，我認爲系統在API版本24中查找libaaudio，當然這並不存在，將minSdkVersion設置爲26即可編譯。 – hellrocker
謝謝！DanAlbert是正確的，aaudio只支持android-O及更高版本。 – Gerry
