Mi aplicación se está ejecutando y trabajando plenamente en el emulador, pero que se estrella en un dispositivo físico

Kenneth Quilantang:

Pueden ustedes ayudarme con mi problema? Mi programa se ejecuta sin problemas en Android Studio emulador (Pixel 2 API 28), pero después de lo instalo en mi teléfono (Samsung Galaxy S8 + API 28), que sólo sigue chocando cada vez que toque el botón de juego :(. Yo también probado en algunos teléfonos y todavía tengo el mismo problema

En realidad, ¿no es cierto mi programa pero lo encontré en youtube pero el que hace el código en youtube me dio la luz verde para usarlo en mi proyecto a largo plazo.

Link del video sobre cómo hacer que el programa en el youtube:

https://www.youtube.com/watch?v=5W3rVBDYFjE

Este es el enlace del código fuente se puede ejecutar:

https://github.com/heyletscode/2D-Game-In-Android-Studio

Todo lo que quiero es ejecutar este código en un dispositivo físico, especialmente en mi teléfono Samsung Galaxy S8 +. Me parece que no puede resolver el problema que estoy un poco desesperada. Soy muy nuevo para programación en Java Lo siento mucho.

Código para la clase com.heyletscode.ihavetofly.Flight a lo solicitado por @Marc

Md. Asaduzzaman:

El problema real es en GameView.java:64 , donde la altura de la pantalla fija y ancho utilizan en lugar de dinámica. Este código funciona sin problemas en el dispositivo con la pantalla inferior o igual 1920x1080 px.

Causará un problema cuando el tamaño de pantalla se pone más que como el screenRatioX y screenRatioY viene <1, el cual a su vez a O en Flight.java:32 por fundido, lo que causó la excepción, ya

anchura y la altura debe ser> 0

Para tamaño de la pantalla Uso dinámico, puede utilizar lo siguiente:

 Display display = getWindowManager().getDefaultDisplay();
 Point size = new Point();
 display.getSize(size);

Uso size.x y size.y en lugar de 1920f y 1080f respectivamente. Gracias

Supongo que te gusta
