Description Song Chen 2013-07-25 19:30:49 UTC
When setting the Android to language Chinese - Traditional, the app will crash when some .net functions are used. For example, string.EndsWith.

From Song Chen:

I am using 4.8.0. You can just simply download the “Hello World” example, and add the string.EndsWith method anywhere, e.g. the button click handler. Then deploy it to a device with language set to Chinese – Traditional, and you will see the app crash after clicking the button.


Steps to reproduce:
1. Set the Android Language to: 中文(繁體)
2. Run the attached example (Android template project, plus a call to string.EndsWith())
3. Click the button
4. The program quits

Change the language to something else, kill the app (or redeploy, or restart the device), run it again, click the button, and the app does not quit.
