getDrawble(int) is deprecated

So for this function now it is advised to pass and int and a theme, In this case how would you do that Drawable drawable = getResources().getDrawable(page.getImageId()); if I make the second parameter null then I get an error and one fix it shows is to add @TargetApi(Build.VERSION_CODES.LOLLIPOP) to the top of the function loadPage Can you explain please.

Hello,

You'll likely want to be using ContextCompat.getDrawable() from the support library. This is the current method for supporting older APIs as well as well. You do have to import ContextCompat. You will need to pass in the context(which will be the activity that you are in most likely) as well as the resource id. For example,

Drawable someDrawable = ContextCompat.getDrawable(this, R.id.drawable_id)

Please let us know if this helps or if you need more assistance.

In this case what would the drawable_id be?

In this case, the R.id.drawable_id would be the call to page.getImageId()

When I had this issue I simply just changed it to this: Drawable drawable = getDrawable(page.getImageId());

I believe when you're doing this, you're using the context's getDrawable(int) method. Looking in the documentation here, you'll notice that method was added in API 21, so if you try running the code on a device(or emulator) prior to API 21, your app will most likely crash.

I just used ContextCompat.getDrawable(context, int id) and it works ok.

private Context mContext; mContext = getApplicationContext(); Drawable drawable = ContextCompat.getDrawable(mContext, page.getImageId());
