SC3056

(or "In dash, ... are not supported." when using dash)

#!/bin/sh
echo "${!ANDROID_*}"

The easiest solution is to switch to a shell that does support name matching prefixes, like bash:

#!/bin/bash
echo "${!ANDROID_*}"

Alternatively, extract the data you want from env or set

Using ${!name*} to find all variable names with a given prefix is a bash and ksh extension that dash and POSIX sh does not support.

If you only intend to target shells that supports this feature, you can change the shebang to a shell that guarantees support, or ignore this warning.

You can use # shellcheck disable=SC3000-SC4000 to ignore all such compatibility warnings.
