I use ndk-gdb of android-ndk-r9d-linux-x86 in ubuntu 12.04 to debug the android native application "hello-jni", but it receive this error.
WARNING: The shell running this script isn't bash. Although we try to avoid bashism in scripts, things can happen.

but the android-ndk-r8e-linux-x86 is ok, i wonder why? Thanks.
I believe 'ndk-gdb' has been deprecated in favor of 'ndk-gdb.py' (although this has not been widely advertised, IMO.) Using r9d, I had the same problem you reported above, but the python version worked without issue.

Change /bin/sh to /bin/bash will solve the warning and the "bad substitution" problem.
