Public methods

compareTo

added in API level 24
public int compareTo (VersionInfo other)

Compares other with this VersionInfo.

Parameters
other VersionInfo: VersionInfo to be compared

Returns
int 0 if the argument is a VersionInfo object that has version information equals to this object. Less than 0 if the argument is a VersionInfo object that has version information greater than this object. Greater than 0 if the argument is a VersionInfo object that has version information less than this object.

equals

added in API level 24
public boolean equals (Object other)

Checks if this version information is equals to the argument version

Parameters
other Object: object to be compared

Returns
boolean true if other is equals to this object's version information, false otherwise

getInstance

added in API level 24
public static VersionInfo getInstance (String version)

Returns an instance of VersionInfo with the argument version.

Parameters
version String: version String in the format of "major.minor.milli.micro" or "major.minor.milli" or "major.minor" or "major", where major, minor, milli, micro are non-negative numbers <= 255. If the trailing version numbers are not specified they are taken as 0s. E.g. Version "3.1" is equivalent to "3.1.0.0".

Returns
VersionInfo an instance of VersionInfo with the argument version.
