Update to CLANG and LLVM's libc++ Library #83

Closed JeremyMColegrove closed 5 years ago

JeremyMColegrove commented 5 years ago

According to Androids CLANG migration "https://android.googlesource.com/platform/ndk/+/master/docs/ClangMigration.md#how-to-fix-common-problems" upgrading to GCC is by removing "NDK_TOOLCHAIN" Also gnustl has been depreciated: "https://developer.android.com/ndk/guides/cpp-support" But 'c++_static' works.' c++_shared' does not (this was just trial and error, correct me if I am wrong). LLVM's libc++ is the C++ standard library that has been used by the Android OS since Lollipop, and as of NDK r18 is the only STL available in the NDK

@Blakletter without this patch I'm not able to compile the library for the current versions: react-native 0.59.8 / NDK 19.2.5345600. But when trying to use it the app crashes, here are the relevant parts of the log I believe:
