ResourcesCompat.getDrawable() vs AppCompatResources.getDrawable()

Question

I\'m a bit confused with these two APIs.

ResourcesCompat.getDrawable(Resources res, int id, Resources.Theme theme)

Return a drawable

Answer 1

Here is my understand after some test

ContextCompat.getDrawable(@NonNull Context context, @DrawableRes int resId)

ResourcesCompat.getDrawable(@NonNull Resources res, @DrawableRes int id, @Nullable Theme theme)

AppCompatResources.getDrawable(@NonNull Context context, @DrawableRes int resId)

VectorDrawableCompat.create(@NonNull Resources res, @DrawableRes int resId, @Nullable Theme theme

The first thing see is VectorDrawableCompat and ResourcesCompat can specific theme

I) Without using

AppCompatDelegate.setCompatVectorFromResourcesEnabled(true); in onCreated of Application class

1) For vector image

• API >= 21

  • ContextCompat work well
  • ResourcesCompat work well
  • AppCompatResources work well
  • VectorDrawableCompat work well

• API < 21

  • ContextCompat crash
  • ResourcesCompat crash
  • AppCompatResources work well
  • VectorDrawableCompat work well

2) For normal image

• In all level
  • ContextCompat work well
  • ResourcesCompat work well
  • AppCompatResources work well
  • VectorDrawableCompat crash

II) Using

AppCompatDelegate.setCompatVectorFromResourcesEnabled(true); in onCreated of Application class

1) For vector image

• In all level
  • ContextCompat work well
  • ResourcesCompat work well
  • AppCompatResources work well
  • VectorDrawableCompat work well

2) For normal image

• In all level
  • ContextCompat work well
  • ResourcesCompat work well
  • AppCompatResources work well
  • VectorDrawableCompat crash
