Lo que si firmo la aplicación como esta: http://mobile.tutsplus.com/tutorials/android/publish-to-android-market/ ¿El usuario todavía necesita tener "aplicaciones no comerciales" habilitado en la configuración? – madcoderz
Sí. Para todos los dispositivos que no estés instalando en el mercado, debes tener habilitada esa casilla de verificación, hasta donde yo sé. Y esa es su intención, así que si encuentras una forma de evitarlo (cosa que dudo), simplemente puedes esperar a que se 'arregle' más adelante. – Nanne
Gracias por su ayuda. Es realmente apreciado. – madcoderz
