Seems like we need to update README for the example app.

@jakub-gonet it is not updated yet. LOL I googled this and got here.
Also, it is confusing it does not tell where to run npx react-native run-android(for android): in root of project or in Examples directory. It may be confusing for some people, for it tells to install packages both in root and in Example directory .At the first place, why NDK is a dependency?
