Studio Android reliant la bibliothèque externe en C++ dans Windows

Question

Quelqu'un peut-il m'expliquer comment lier correctement la bibliothèque externe écrite en C++ dans le projet ndk?

J'essaie d'utiliser la bibliothèque SDL comme décrit dans cette vidéo: https://www.youtube.com/watch?v=BSBISI0sCqo&t=306s mais le problème se produit lorsque je tente d'exécuter l'une des commandes dans le terminal:

F:/Programmation/Android/Indie/app/src/main/cpp> C:/Users// AppData/Danijel locales/Android/sdk/NDK faisceau/NDK-build NDK_LIBS_OUT = ../jniLibs

ce résultat appel en erreur :

Android NDK: APP_PLATFORM non défini. Valeur par défaut de la version prise en charge minimum android- 14. Android NDK: votre APP_BUILD_SCRIPT pointe vers un fichier inconnu: F: /Programming/Android/Indie/app/src/main/cpp/jni/Android.mk C:/Users/Danijel/AppData/Local/Android/SDK/ndk-bundle/build //../ build/core/add-appl ication.mk:101: *** Android NDK: Abandonner .... Arrêtez. Donc, je sais que le chemin actuel contient le dossier cpp (que je ne peux pas renommer en jni), pas jni, mais la même chose arrive quand j'essaie de définir le chemin dans Gradle.
