7 errors total when Build Target is set to Ice Cream Sandwich:

Comment 2 PJ 2012-04-23 16:26:30 UTC
This is now the issue on Froyo and Gingerbread. On Ice Cream Sandwich the build errors persist:

Steps to reproduce:
1. Open 'ViewPagerIndicator'.
2. Build the application.
3. Run the application.
4. Verify application launch successfully.
5. Click 'Circles->Default'.
6. 'System.ArgumentException has been thrown.

Actual result:
After clicking on 'Circles->Default' following error displayed 'System.ArgumentException has been thrown'

Expected result:
Application should run successfully after clicking 'Circles->Default'.

Stack trace:
System.ArgumentException: Unable to determine JNI class for 'Android.Support.V4.View.ViewPager'.

The listener-related breakage is fixed:


Color related breakage is fixed:


The "JNI class" error is fixed in 240492ec.

You'll also need the Support fix in b43e81da.

ViewPagerIndicator launches for me, though I haven't explored the entire app...
Comment 4 PJ 2012-04-24 10:38:47 UTC
Circles->Default is no longer an issue (I personally verified) at least on an HTC Flyer.

The build issues when target framework is set to Ice Cream Sandwich remain:

I can re-file this as a separate issue if you'd like, but re-opening for now.
