The method managedQuery(Uri, String[], String, String[], String) from the type Activity is deprecated

问题

When I compile the following code

cursor = activity.managedQuery( imageUri, proj, null, null, null );

I get following warning

The method managedQuery(Uri, String[], String, String[], String) from the type Activity is deprecated

The code is working fine. What should I do to avoid this?

回答1:

The managedQuery method is deprecated, meaning it should no longer be used and there is an updated method available. The replacement for this is getContentResolver().query():

cursor = activity.getContentResolver().query(imageUri, proj, null, null, null);

You can normally find out why the method is deprecated, and what you should use instead, by a quick Google of the method name, or depending on how good the javadoc is it may inform you through your IDE.

The above answer is very apt. I just wanted to add to this thread more info as to why managedQuery is deprecated. Here is a nice explanation for why the managedQuery is replaced by getContentResovler().query()
