Cómo autopublicarse la aplicación android

• Sin conocimientos adicionales, y pueden instalarse con un solo clic. Sin embargo, tienen que tener la instalación de "aplicaciones no comerciales" habilitada en los ajustes.
• Las notificaciones de actualización sólo pueden funcionar si la programa en su aplicación. Solicitar algún tipo de bandera de su sitio o algo. Así que no hay apoyo básico para eso
• No es necesario desinstalar ni reinstalar. Cuidado con su versionNumber sin embargo.

-¿El usuario necesitaría algún conocimiento adicional para poder instalar la aplicación? Sí. No puede instalar aplicaciones no firmadas sin autorizar la instalación de "Fuentes desconocidas" en la configuración de las aplicaciones.

-¿El usuario puede instalarlo con un solo clic? Nope. Él tiene que obtener su sitio, descargarlo, abrirlo y aprobar que quiere instalarlo.

-¿Y las actualizaciones, el usuario puede recibir una notificación cuando hay una nueva versión? Creo que el soporte de actualización es solo para aplicaciones de mercado. Tendrás que escribir algo tú mismo

-¿El usuario necesitaría unistall y volver a instalar la aplicación al actualizar a una versión más reciente? Ver respuesta anterior – depende de cómo implementarlo.
