IOError: [Erro 2] Nenhum arquivo ou diretório: u '/… / RetroApp-debug.apk'
Sou iniciante em programação de bibliotecas kivy, mas fiz uma aplicação muito simples, como no tutorial do Kivy. Na área de trabalho, ele funciona bem. Mas do que eu queria fazer o arquivo .apk (não tinha usado o Linux). Eu tentei várias etapas para criar um arquivo .apk, mas finalmente quando instalei e abri este programa. Ocorreu um erro. Eu tentei muitas especificações e new_android, mas nada funcionou. Finalmente atualizei meu buildozer para a última versão. Mas agora, após a depuração do buildozer android, ele escreve este erro:
IOError: [Erro 2] Esse arquivo ou diretório não existe: u '/ home / kivy / reyyy / .buildozer / android / platform / build / dists / RetroApp / build / outputs / apk / RetroApp-debug.apk'.
