Why getDrawable() doesn't work on some Android devices?

Question

I am getting \"nosuchmethod error\" on some user\'s phones (eg. Motorola Razr i) but it works fine on my HTC. Below is the code.

Drawable rBlack;
rBlack = getRes         


        

Answer 1

I'm going to bet it is failing on getDrawable(R.drawable.rblack, getTheme()); which was added in API 21. Change that line to:

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