mresolver = Ctx.getcontentresolver (); The top of the CTX is a context,activity.this is that context, this context is equivalent to a contextual environment. Once you get this context, you can call the Getcontentresolver interface to get the Contentresolver instance. Contentresolver instances obtained, you can make a variety of queries, the following I take the audio database as an example to explain the method of adding and deleting, video and image and audio very similar.
