I'm trying to upgrade my app from API19 to API21

The main changes I've made to the gradle properties are:

compileSdkVersion 21
buildToolsVersion "21.0.2"

minSdkVersion 8
targetSdkVersion 21


compile 'com.android.support:appcompat-v7:21.0.0'

The app builds ok, but I always get the following error:

I've tried the version 4 (which I was using previously) and the v7 ActionBarDrawerToggle (with a change to the new format for the constructor) but always get the same error. The apps theme is a parent of Theme.AppCompat.Light.DarkActionBar

I'm not really sure what to look at.

I had the same problem when trying to use ?attr/selectableItemBackground and based on your answer and some digging around on the internet I found out what was wrong for me (and probably you as well).

From this answer I learned that "? mark is used to reference style in current theme." Which means that when you use ?attr/ you refer to something in the current theme.

I noticed that I got this crash only when inflating using the application context and not when using the activity context. This blog post explains what's happening in "Context Capabilities" section.

...[When using the application context] inflation will be done with the default theme for the system on which you are running, not what’s defined in your application.

This mean that ?attr/ won't work since they refer to the current theme, not the default system theme you're inflating with.

So ?attr/ works fine if you make sure to inflate using the Activity context instead of the application context.
