Proposing to add tips to `doctor`

[romeerez]

For me react-native doctor was showing that "Android Studio not found" and "Android SDK" is not found. And I even could not google anything how it tries to find it. So I went to source code, find that cli use envinfo package for this, went to envinfo source and discovered that android studio must be in /opt/android-studio/bin/studio.sh and SDK info must come from sdkmanager terminal utility which was not working.

To solve it:

• make symbolic link from studio.sh that you have to /opt/android-studio/bin/studio.sh
• sdkmanager requires JDK 8, and I had 14, install it and then put JAVA_HOME="/usr/lib/jvm/java-8-openjdk" to your .zshrc or .bashrc (update path to yours jdk)

Please add some help to doctor

I used doctor because react-native run-android just silently hangs, and this is not good

@romeerez: thanks for proposing this, the more I think about it the more I like it.

I'll try to get a small experience ready for this so we can evaluate it, I was thinking about that the CLI can, perhaps, show a few bullet points explaining how it tried to find the SDK or whatever other software, something like:

- Android
	○ SDK ❌
		- Found `ANDROID_HOME` path at `/path/to/android`;
		- Found SDK path at `/path/to/sdk`;
		- Important file (`random_file.sh`) not found.

This can, of course, get pretty extensive so I would recommend hiding it under a flag, something like --tips.

Thoughts?

I don't think that it may get extensive, there is a small amount of such checks, but it would be helpful for sure. If it's unwanted to get verbose doctor report, at least would be nice to have a tip how to get tips

[lucasbento]

There are quite a few checks inside of envinfo that would be nice to have covered.

If doctor outputs an error we can show a message that using the --tips flag can be useful.
