Cómo obtener contactos en Android
Estoy desarrollando una aplicación para componer sms en la plataforma android. Para eso necesito conseguir "Contactos", "Contactos Recientes" y "Grupos". Por favor, dígame cualquier tutorial o el código de cómo hacerlo. Al hacer clic en cualquiera de estos tres botones debe haber contactos junto con una casilla de verificación para la selección de múltiples contactos. Gracias.
Aquí está el código para obtener contactos programáticamente
