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.

the apk is too large,you can download apk by this url.and the so file name is libhellfire.so https://play.google.com/store/apps/details?id=com.grabtaxi.passenger Thanks for you work!

chame1eon commented 5 years ago

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

onegithuber commented 5 years ago

yes ,it did. but the symbol is unknowed.

chame1eon commented 5 years ago

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 commented 5 years ago

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.

chame1eon commented 5 years ago

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