[LLVMdev] ASan for Android Applications

[Evgeniy Stepanov]

You are citing the "Android platform workflow" section, which is about
sanitizing components of the Android system itself.
For NDK apps, see "Android NDK workflow" in the same document.

You need -eng build because preloading libraries into dalvik vm is not
allowed in user builds. JellyBean includes several bugfixes in the
dynamic loader that asan needs.

Was there any useful output in adb logcat when your program crashed?
