TvContract.Channels.Logo

public static final class TvContract.Channels.Logo
extends Object

A sub-directory of a single TV channel that represents its primary logo.

To access this directory, append CONTENT_DIRECTORY to the raw channel URI. The resulting URI represents an image file, and should be interacted using ContentResolver.openAssetFileDescriptor.

Note that this sub-directory also supports opening the logo as an asset file in write mode. Callers can create or replace the primary logo associated with this channel by opening the asset file and writing the full-size photo contents into it. (Make sure there is no padding around the logo image.) When the file is closed, the image will be parsed, sized down if necessary, and stored.

Usage example:

 public void writeChannelLogo(long channelId, byte[] logo) {
     Uri channelLogoUri = TvContract.buildChannelLogoUri(channelId);
     try {
         AssetFileDescriptor fd =
             getContentResolver().openAssetFileDescriptor(channelLogoUri, "rw");
         OutputStream os = fd.createOutputStream();
         os.write(logo);
         os.close();
         fd.close();
     } catch (IOException e) {
         // Handle error cases.
     }
 }

Inherited methods

From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait(long millis, int nanos) Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed. final void wait(long millis) Causes the current thread to wait until either another thread invokes the notify() method or the notifyAll() method for this object, or a specified amount of time has elapsed. final void wait() Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object.
