Public Methods

public Bitmap getFavicon ()

Since: API Level 1

Return the favicon of this history item or null if no favicon was found.

Returns
  • A Bitmap containing the favicon for this history item or null. Note: The VM ensures 32-bit atomic read/write operations so we don't have to synchronize this method.

public int getId ()

Since: API Level 1

This method is deprecated.
This method is now obsolete.

Return an identifier for this history item. If an item is a copy of another item, the identifiers will be the same even if they are not the same object.

Returns
  • The id for this item.

public String getOriginalUrl ()

Since: API Level 3

Return the original url of this history item. This was the requested url, the final url may be different as there might have been redirects while loading the site.

Returns
  • The original url of this history item.

public String getTitle ()

Since: API Level 1

Return the document title of this history item.

Returns
  • The document title of this history item. Note: The VM ensures 32-bit atomic read/write operations so we don't have to synchronize this method.

public String getUrl ()

Since: API Level 1

Return the url of this history item. The url is the base url of this history item. See getTargetUrl() for the url that is the actual target of this history item.

Returns
  • The base url of this history item. Note: The VM ensures 32-bit atomic read/write operations so we don't have to synchronize this method.

Protected Methods

protected synchronized WebHistoryItem clone ()

Since: API Level 1

Clone the history item for use by clients of WebView.

Returns
  • a copy of this object.

protected void finalize ()

Since: API Level 1

Invoked when the garbage collector has detected that this instance is no longer reachable. The default implementation does nothing, but this method can be overridden to free resources.

Note that objects that override finalize are significantly more expensive than objects that don't. Finalizers may be run a long time after the object is no longer reachable, depending on memory pressure, so it's a bad idea to rely on them for cleanup. Note also that finalizers are run on a single VM-wide finalizer thread, so doing blocking work in a finalizer is a bad idea. A finalizer is usually only necessary for a class that has a native peer and needs to call a native method to destroy that peer. Even then, it's better to provide an explicit close method (and implement Closeable), and insist that callers manually dispose of instances. This works well for something like files, but less well for something like a BigInteger where typical calling code would have to deal with lots of temporaries. Unfortunately, code that creates lots of temporaries is the worst kind of code from the point of view of the single finalizer thread.

If you must use finalizers, consider at least providing your own ReferenceQueue and having your own thread process that queue.

Unlike constructors, finalizers are not automatically chained. You are responsible for calling super.finalize() yourself.

Uncaught exceptions thrown by finalizers are ignored and do not terminate the finalizer thread. See Effective Java Item 7, "Avoid finalizers" for more.
