* fix for android crash For some reason, a recent commit removed the check for a null return from `getCurrentActivity()`. But since `getCurrentActivity()` might return null, the app will crash with a NullPointerException. This restores the null check. It also fixes inconsistent handling of null `tag` argument in both iOS and Android. This does not affect usage from JS because the JS interface will not pass null to that argument; however other native code could still call these methods and pass null for `tag`. * remove unnecessary parens --------- Co-authored-by: Marc Shilling <marcshilling@gmail.com>
