mayLaunchUrl

added in version 24.1.0
boolean mayLaunchUrl (Uri url, 
                Bundle extras, 
                List<Bundle> otherLikelyBundles)

Tells the browser of a likely future navigation to a URL. The most likely URL has to be specified first. Optionally, a list of other likely URLs can be provided. They are treated as less likely than the first one, and have to be sorted in decreasing priority order. These additional URLs may be ignored. All previous calls to this method will be deprioritized.

Parameters
url Uri: Most likely URL.
extras Bundle: Reserved for future use.
otherLikelyBundles List: Other likely destinations, sorted in decreasing likelihood order. Inside each Bundle, the client should provide a Uri using KEY_URL with putParcelable(String, android.os.Parcelable).

int postMessage (String message, 
                Bundle extras)

Returns
int An integer constant about the postMessage request result. Will return RESULT_SUCCESS if successful.
