Use ContextCompat to retrieve drawables

Given I'm injecting a drawable into my fragment like that:

@DrawableRes(R.drawable.bg_button_with_stroke_orange)
protected Drawable backgroundDrawable;

Then Android Annotations generates this code:

private void init_() {
    Resources resources_ = context_.getResources();
    backgroundDrawable = resources_.getDrawable(drawable.bg_button_with_stroke_orange);
}

Which then generates this compiler warning for targetSdk=22 builds:

TheClass_.java:33: warning: [deprecation] getDrawable(int) in Resources has been deprecated
        backgroundDrawable = resources_.getDrawable(drawable.bg_button_with_stroke_orange);

Instead, AndroidAnnoations should, given the class ContextCompat is available, generate this:

private void init_() {
    backgroundDrawable = ContextCompat.getDrawable(context_, drawable.bg_button_with_stroke_orange);
}

Benefits:

Obviously, the compiler warning would be gone
More importantly, the theme will be applied to the drawable on Lollipop+ devices
