WARNING: Unmaintained code ahead
As an alternative please try out Google's own FPL Utils - NDK perf, which provides a non-intrusive way to profile your applications using Linux perf. However be warned that this too is only supported on 2 somewhat-obsolete devices.
The general churn in Android means that this library has suffered some severe bit-rot over the last couple of years. If you can help then pull requests are appreciated, but I no longer have the time or motivation to work on the project.
Profile Android NDK code. Further instructions on the docs/Usage.md page.
