): Bitmap!

A convenient helper method to get the channel logo associated to the given channel ID from the system content provider.

Parameters

storeChannelLogo

open static fun storeChannelLogo(
    @NonNull context: Context, 
    channelId: Long, 
    @NonNull logoUri: Uri
): Boolean

Stores channel logo in the system content provider from the given URI. The method will try to fetch the image file and decode it into Bitmap. Once the image is successfully fetched, it will be stored in the system content provider and associated with the given channel ID.

The URI provided to this method can be a URL referring to a image file residing in some remote site/server, or a URI in one of the following formats:

content (android.content.ContentResolver#SCHEME_CONTENT)
android.resource ( #SCHEME_ANDROID_RESOURCE)
file (android.content.ContentResolver#SCHEME_FILE)

This method should be run in a worker thread since it may require network connection, which will raise an exception if it's running in the main thread.

Parameters
`context`	Context: the context used to access the system content provider
`channelId`	Long: the ID of the target channel with which the fetched logo should be associated
`logoUri`	Uri: the `Uri` of the logo file to be fetched and stored in the system provider

Return
`Boolean`	`true` if successfully fetched the image file referred by the give logo URI and stored it in the system content provider, or `false` if failed.
