You can get the location of the C function that caused the crash using the Android NDK Stacktrace Analyzer.
The steps are on the wiki, but basically you need to get the stack trace from logcat into a file (adb logcat > mycrash.log
), then dump your library to a text file, then run the program on the two of them. Here's the shell script I use to do the lot:
#!/bin/sh
if test $# -lt 2 ; then
echo "Extract readable stack trace from Android logcat crash"
echo "Usage $0 lib.so crash.log"
exit 1
fi
of=$(mktemp)
echo "Disassemble $1"
~/tools/android-ndk-r5/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-objdump -S $1 > $of
echo "Parse stack trace in $2"
~/bin/parse_stack.py $of $2
Change the paths to the Android NDK and parse_stack.py file as you need.
