A regex pattern problem in PointSettings, in Android

[kadhikary]

In Android, the client seems to be unable to instantiate the PointSettings class, possibly due to an error in the Pattern regex at this line :

private static final Pattern ENV_PROPERTY = Pattern.compile("(\$\{env\.)(.+)(})");

I wonder if this is needed 👍
"(\\$\{env\\.)(.+)(})"

There is another Pattern next to this line.
