Remarks

Guesses canonical filename that a download would have, using the URL and contentDisposition.

File extension, if not defined, is added based on the mimetype.

The contentDisposition argument will be treated differently depending on targetSdkVersion.

<ul> <li>For targetSDK versions < VANILLA_ICE_CREAM it will be parsed based on RFC 2616. <li>For targetSDK versions >= VANILLA_ICE_CREAM it will be parsed based on RFC 6266. </ul>

In practice, this means that from VANILLA_ICE_CREAM, this method will be able to parse filename* directives in the contentDisposition string.

The function also changed in the following ways in VANILLA_ICE_CREAM:

<ul> <li>If the suggested file type extension doesn't match the passed mimeType, the method will append the appropriate extension instead of replacing the current extension. <li>If the suggested file name contains a path separator ("/"), the method will replace this with the underscore character ("_") instead of splitting the result and only using the last part. </ul>
