Resources.NotFoundException thrown on res/color/secondary_text_dark.xml

Question

I've received a crash report with an error caused by a Resource.NotFoundException. What is strange, however, is that it is thrown by the Android compatibility library in a DialogFragment when it is trying to use the res/color/secondary_text_dark.xml colour (during its creation). This is an Android resource (found in android.R.color.secondary_text_dark), so I assume that every device should have this available.

I have an idea that the exception is caused because Proguard has obfuscated the resources, but I'm not sure how to avoid this. I am not able to reproduce the crash on my Nexus One, so I will not be able to check if a change fixes this.

Am I right about the obfuscator or are there any other things which could cause this?

Thank you very much.

I've attached the log here:

</LinearLayout>

The textColor in the first TextView refers to this in my colors.xml file

<color name="ltgrey">#ffe0e0e0</color>

Answer 1

it is thrown by the Android compatibility library in a DialogFragment when it is trying to use the res/color/secondary_text_dark.xml colour (during its creation). This is an Android resource (found in android.R.color.secondary_text_dark), so I assume that every device should have this available.

Android is trying to load R.color.secondary_text_dark, not android.R.color.secondary_text_dark, based upon your stack trace.
