Permiso de escritura de archivos de Android 6.0 denegado

Yo estaba ejecutando un código antiguo que se utiliza para trabajar en Android 5.1. Ahora no funciona con el siguiente error en FileOutputStream ( EACCES (Permission denied) ) .

¿Cualquier entrada?

• No apuntar a las últimas versiones de Android
• Cómo actualizar automáticamente android: versionName?
• Uso de atributos desde el nivel API más allá de minSdkVersion
• ¿Es posible incluir / importar código al Manifiesto de Android?
• INSTALL_FAILED_CONFLICTING_PROVIDER en Android

1. Versión del SDK: 23
2. Todos los permisos proporcionados en el manifiesto.

código:
