Hi. Thanks for your bug report! I have had a look at the issue and have pushed a fix to PyPi. Please try version 2.2.2 and see if that works for you. I was not able to reproduce the error so if you can send me the application you were testing with I can try to make a better fix. Thanks.

Thanks for you work!

Thanks. Will download and try with grab taxi. Did the update I pushed yesterday work for you?

[onegithuber]

yes ,it did.
but the symbol is unknowed.

[chame1eon]

Okay, at least it is running now. I will take a look and see if I can figure out why the symbol was not resolving for that application you were using. It will be a couple of weeks until I have access to an Android ARM device to test with.

[chame1eon]

Thanks for sending your test app, I have now tried it on an Android phone testing with the hellfire binary. I found out that the hellfire library does not have DebugSymbols for those functions in the jnitrace backtrace. As such, jnitrace cannot output the symbol information. I have, however, improved the output of jnitrace so that it will now show you the relative address for the backtrace function, rather than "unknown", so that you can go and take a look at it in a dissembler. Thanks for your bug report! Closing this as the crash is resolved.

Oh and those improvements to the backtrace output are available in version 2.2.3.
