manual de android en pdf

Question

Estoy recibiendo un "error nosuchmethod" en los teléfonos de algunos usuarios (por ejemplo, Motorola Razr i) pero funciona bien en mi HTC. A continuación se muestra el código.

Drawable rBlack;
rBlack = getResources().getDrawable(R.drawable.rblack, getTheme());
java.lang.NoSuchMethodError: android.content.res.Resources.getDrawable

Y si uso este código:

flipButton.setImageDrawable(getDrawable(R.drawable.rblack));

Me sale este error

Answer 1

Intenta agregar la siguiente línea de código:

context.getResources().getDrawable(R.drawable.your_image_name);

Answer 2

Voy a apostar que está fallando en getDrawable(R.drawable.rblack, getTheme()); que se agregó en API 21. Cambie esa línea a:

if(android.os.Build.VERSION.SDK_INT >= 21){
rBlack = getResources().getDrawable(R.drawable.rblack, getTheme());
} else {
rBlack = getResources().getDrawable(R.drawable.rblack);
}

Answer 3

ContextCompat.getDrawable(Context context, int id)
