Crash in the application in the libc

I am getting a crash in the application in the libc. I dont know the reason, please help me if anyone knows about this crash.

I got this information in the website, but i dont have any shared resources (other than one .so file as library) and this didn't resolved my issue.

Regards, SSuman185

You might get a better idea of where your error is by using the addr2line tool. You can do something like:

arm-linux-androideabi-addr2line -e libc.so -C 0005d050

The strace tool may also provide some insight if you have a dev phone.

Thanks for your support. Actually in my code i was doing byte to short conversion which was corrupting the heap. I dont know how its getting corrupted even after allocating sufficient memory. After i moved this byte to short conversion to the native layer in the decoder, i am not getting crash now.

thought it may help you guys. So, conclusion is not only for native, even when there is any corruption in memory in java layer also, i am getting the dump with libc. Which was misleading me to concentrate on native layer even though the problem was in Java layer.

Thanks & Regards,
