Tengo una aplicación simple para que ingreses texto en la vista de texto y presionas enviar y muestra el texto en otra actividad. Sin embargo, cuando presiono "Enviar", me da el mensaje "Desafortunadamente, el mensaje ha detenido". Miré otros hilos en SO, peroDesafortunadamente myfirstproject dejó de funcionar error en java Parece el más cercano y dijeron que verificara el archivo LogCat, y se le ocurrió más de un error:
