[FIXED] Alternative for Formatter.formatIpAddress(int);

Issue

I'd used this code in my application, but the warning says its : "The method formatIpAddress(int) from the type Formatter is deprecated"

android.text.format.Formatter.formatIpAddress(mWifiManager.getConnectionInfo().getIpAddress());

what's the quick fix for this?

Solution

The documentation states

Use getHostAddress(), which supports both IPv4 and IPv6 addresses. This method does not support IPv6 addresses.

where getHostAddress() refers to InetAddress.getHostAddress().

However, WifiInfo just has a ipv4 address as an int and AFAIK there's no practical way to convert it to an InetAddress. The deprecation is because the function doesn't support ipv6 but neither does WifiInfo. So I'd say just use formatIpAddress() because it works and add @SuppressWarnings("deprecation") to get rid of the warning.
