Ich versuche ein einfaches Hello World -Programm auf meinem Android -Telefon zu montieren und auszuführen. Mein Host -Laptop ist ein Ubuntu 22.04 64 -Bit -System. Ich habe den Android-Ndk-R27C heruntergeladen und an meinen Android-Ordner extrahiert, in dem mein SDK bereits angewiesen ist. /HOME/Entwickler/Android/Android-NDK-R27C-Linux/Android-NDK-R27C/Toolchains/LLVM/Prebuilt/Linux-X86_64/bin
