Local preview works fine, but Android preview or build don’t work at all. Here’s the log from build command ```auto > fuse build --target=Android --run -v .... ....

Thanks for reporting this. Our crew will look into it tomorrow. ---

Hey! Those errors indicate that the app is somehow being built with an out-of-date C++ compiler (the source lines use C++11 features). Try running `fuse install android` in a terminal, and let us know if that helps! Cheers! ---

Hello Olle, Running `fuse install androidz doesn’t do anything for me, because I’ve already done that and provided paths to Adnroid SDK and NDK installed with Xamarin a while back. I’m using the current Fuse Tools 0.11. I’ve been constantly installing Android Platform SDK up to Android 6.0 (API Level 23) and I have most the following API Level SDKs installed: 23, 22, 21, 19, 16. I’m continuously developing a Cordova app and they build fine. I have NDK version r8b and the current is r11b. Isn’t the C++ compiler part of the NDK? I’ll try upgrading the NDK and see if it helps. Cheers, Maks ---

Hey again Maks, Yeah, the C++ compiler comes with the NDK. What directories do you have that match `$YOUR_NDK_DIR/toolchains/arm-linux-androideabi-*`? It looks like Fuse will use GCC 4.9, 4.8, or 4.6 (in that order), but it’s possible that we don’t actually still support e.g. GCC 4.6. ---

Hi Olle, According to your instructions NDK r8b uses GCC 4.6. I deleted the old NDK I had, downloaded the new one which uses GCC 4.9 and ran `fuse install android` again. I used the path where I extracted the new NDK and now everything works fine 🙂 I think this requires updating the guide [Export for Android](https://www.fusetools.com/learn/guides/preview-and-export-android) a bit to inform that you need to specify a minimum NDK version when choosing an existing installation. Thanks for your help. Best, Maks ---

That’s great news! I’ve also created an internal issue to investigate more in depth what went wrong there. Thanks for your report!
