textSize is not defined in the platform's base theme.
These are the text size-related attributes in the theme:
!-- Default appearance of text: color, typeface, size, and
style. --
attr name=textAppearance format=reference /
!-- Default appearance of text against an inverted background:
color, typeface, size, and style. --
attr name=textAppearanceInverse format=reference /
!-- Text color, typeface, size, and style for large text.
Defaults to primary text color. --
attr name=textAppearanceLarge format=reference /
!-- Text color, typeface, size, and style for medium text.
Defaults to primary text color. --
attr name=textAppearanceMedium format=reference /
!-- Text color, typeface, size, and style for small text.
Defaults to secondary text color. --
attr name=textAppearanceSmall format=reference /
!-- Text color, typeface, size, and style for large inverse text.
Defaults to primary inverse text color. --
attr name=textAppearanceLargeInverse format=reference /
!-- Text color, typeface, size, and style for medium inverse
text. Defaults to primary inverse text color. --
attr name=textAppearanceMediumInverse format=reference /
!-- Text color, typeface, size, and style for small inverse text.
Defaults to secondary inverse text color. --
attr name=textAppearanceSmallInverse format=reference /
So the textSize attribute is rarely set as part of the base platform, except
inside of a TextAppearance style:
http://developer.android.com/reference/android/R.styleable.html#TextAppearance
So generally I wouldn't expect that code to work, unless textSize has been
explicitly supplied by you in a theme. Instead, you need to retrieve the
resource of the TextAppearance size you want, and then can retrieve the
textSize from that.
That said, what *should* happen is you just get the default value you passed
in, because the theme doesn't hold its own value. You should never get a
crash. The obtainStyledAttributes() method is supposed to build an array of
values that corresponds to the array you passed in to it. So a crash like
this is completely independent of whatever is defined in the theme, and just
an outright bug in whatever platform code it is running on.
Also your code has another issue where it is using array.getResourceId() --
once you do get down to the TextAppearance, generally the values there are
literals, not references to other resources. So this also will always fail
(it doesn't have a resource id), even if textSize does have a value, again
resulting in you getting your default value. You should just call
getDimensionPixelSize() with the array offset at which you want to retrieve
your value -- 0 in your case.
Oh.
That is probably the crash. :) If for some reason there *is* some value for
textSize, if getResourceId() returns non-0, then you will pass a value 0
to getDimensionPixelSize(), which is outside the array you originally passed
in.

I'm getting this exception:

I'm expecting a standard value from the system since thats what I'm asking
for.
It actually works on all devices I can get my hands on and of course the
error reporting doesn't tell me anything useful except a stack trace.
Does anyone have a solution that might work instead of this one?
Does anyone know what device this might be?
I do know that it has to be a 2.2 device or better because I've made the
minimum 2.2 (froyo)
At the moment the only idea I can come up with is to simply send a static
value, but I'm obviously going to have to guess what the device is.
