UnsatisfiedLinkError: dlopen failed: cannot locate symbol "strtof" referenced by "libsupportjni.so" on API <20
android, android-studio, debugging
Solution
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
Problem
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 ``` D/dalvikvm: Trying to load lib /mnt/asec/[[packagename]]-1/lib/libsupportjni.so 0x41b13f30 E/dalvikvm: dlopen("/mnt/asec/[[packagename]]-1/lib/libsupportjni.so") failed: dlopen failed: cannot locate symbol "strtof" referenced by "libsupportjni.so"...
