Public Methods

public static String formatFileSize (Context context, long sizeBytes)

Added in API level 3

Formats a content size to be in the form of bytes, kilobytes, megabytes, etc. If the context has a right-to-left locale, the returned string is wrapped in bidi formatting characters to make sure it's displayed correctly if inserted inside a right-to-left string. (This is useful in cases where the unit strings, like "MB", are left-to-right, but the locale is right-to-left.)

Parameters
context Context: Context to use to load the localized units
sizeBytes long: size value to be formatted, in bytes
Returns
String formatted string with the number

public static String formatIpAddress (int ipv4Address)

Added in API level 3

This method was deprecated in API level 12.
Use getHostAddress(), which supports both IPv4 and IPv6 addresses. This method does not support IPv6 addresses.

Returns a string in the canonical IPv4 format ###.###.###.### from a packed integer containing the IP address. The IPv4 address is expected to be in little-endian format (LSB first). That is, 0x01020304 will return "4.3.2.1".

Parameters
ipv4Address int
Returns
String

public static String formatShortFileSize (Context context, long sizeBytes)

Added in API level 5

Like formatFileSize(Context, long), but trying to generate shorter numbers (showing fewer digits of precision).

Parameters
context Context
sizeBytes long
Returns
