android - UnsatisfiedLinkError: dlopen failed: cannot locate symbol "strtof" referenced by "libsupportjni.so" on API <20

Question

I'm getting the following error immediately on launch, but only for devices running API <20.

**edit: I initially reported this in Android Studio 2.4, and it's still an issue in Android Studio 3.0 stable

Answer 1

Go to Run -> Edit Configurations -> Profiling, and disable "Enable advanced profiling". This feature is not currently compatible with API <20, and will cause this or similar crashes. This may be fixed in the future, but as of Android Studio 2.4 preview 7, it's an open issue. Related issue
