Android fixes

[mhsmith]

• Clarify that the user-facing Android and iOS versions can be found in platform.release, not platform.version, which is a kernel build number that's much less likely to be useful.

• Don't capture stderr from android-env.py. This allows it to display the message "Installing NDK - this may take several minutes", which is quite important, otherwise the user will probably think the script has hung.

• Previously the NDK was detected only by checking for the existence of its directory, which will be left in an unusable state by interrupted installations. Fixed by checking for the package.xml file, which sdkmanager creates after installation is complete.

• Fix a couple of warnings found by linters: use of an undefined payload variable in Android/__main__.py, and defining an unused it variable in MainActivity.kt.

Can you have a better title? it does not really say what it does

[mhsmith]

Sorry, description updated. There isn't really a better title, since the only thing these bugs have in common is Android, but since they're all very small,I thought it was better to put them all in the same PR to avoid multiplying the backports.
