What libc implementation is used in Android platform? What malloc implementation is used (ptmalloc or tcmalloc or anything other)?
libc is Bionic and malloc is Doug Lea version named dlmalloc (with USE_LOCKS enabled for thread-safety).
Update: dlmalloc was removed in january 2016: https://github.com/android/platform_bionic/commit/c650447239352d43acc2fd99a8579a85ae0469ab https://sourceforge.net/p/android-x86/bionic/ci/0ac0cee0d1ab60a92103a5021e76ec31da2e3234/ “Merge “Remove dlmalloc.””
So, Android 7 uses external malloc implementation jemalloc (from FreeBSD/Facebook) – http://jemalloc.net/ and https://github.com/jemalloc/jemalloc; android variant of code is there: https://android.googlesource.com/platform/external/jemalloc/
