Hi,

I’m trying to use the facebook SDK and i downloaded your NativeFacebookLogin sample from GitHub: [https://github.com/fusetools/fuse-samples/tree/feature-NativeFacebookLogin/Samples/NativeFacebookLogin](https://github.com/fusetools/fuse-samples/tree/feature-NativeFacebookLogin/Samples/NativeFacebookLogin)

I filled the appID in the FacebookAppId.uxl file (i did no more changes), but when i’m compiling for android using -DGRADLE (just the way it says in the example), i get this error, am i missing something or it’s a bug?:

I’m using fuse 0.27.1 and win 8.1.

What’s listed in the log file the C++ compiler points to?

`C:/wit-labs/Proyectos/NativeFacebookLogin/build/Android/Debug/FacebookLoginExample/app/build/tmp/compileMainActivityArmeabi-v7aDebugSharedLibraryMainActivityMainCpp/output.txt`

Also: what happens when you run with the `--info` toggle as suggested?

Hi Cristian,

You have found a bug! Luckily it’s one I’ve already fixed otherwise, in our effort to appear bug free, we would have to delete your account, you, and all evidence of this problem 😛

The issue was that, internally, I had a mistake in how I was mapping the Uno types to Java types. The fix for this is in the next release so please hang tight and we will get it out asap.

Thanks for reporting this
