Sign the apk before running for this case to avoid crash.

As a safe workaround is perfect. I can delete the file that generates the problem, but for developers in countries with other encodings, this can be a nightmare! – Tano Mar 08 '15 at 21:35
This doesn't seem to work anymore. I just wiped the emulator's data to continue with the development and tried not to add files with non-ascii characters. – Adrián Pérez Sep 11 '16 at 16:06

sounds insane, why should I sign if I still developing my app? – user924 Oct 29 '17 at 15:58
As mentioned by Tano deleting files will make yourself tired and bored. Signing APK is relief for you. – Ganesh Kanna Oct 31 '17 at 05:12

If this happens for files OUTSIDE (not bundled in) your apk, just test on a real device. For me the emulator was causing the issue.
