Avoiding IllegalArgumentException when using NULL as placeholder value in query?

I'm trying to get contacts photo from content providers and facing some kind of issue with this query.

Cursor p开发者_高级运维hoto = cr.query( 
                   PicURI,  
                   new String[] {
                      CommonDataKinds.Photo.PHOTO
                   }, 
                   Data._ID + "=?",  
                   new String[] { photoId }, 
                   null);

This is the related line from logcat:

java.lang.IllegalArgumentException: the bind value at index 1 is null

After some tests,i figured out that I get this exception if one of the contacts have no picture set.

I searched and found this same problem. Seems like it's a bug. And I can't solve it. Any help will be appreciate.

You certainly don't want to find photos with id=null, so you have to use this code:

if (photoId != null) {
   //your code here
}

Would be nice, if you posted full stack trace.

You're correct - it is the same problem as this:

You're also correct about it's being a bug.

The "bug" is in your code. You need to check your arguments for "nulls", and you should NOT do a query or an update if any of your input parameters are null!

Two choices:

if (myphoto[i] == null)
  query.bindNull(i)

... or ...

if (myphoto[i] != null)
  query ()

It's YOUR responsibility to validate and clean up YOUR data before calling an API...

IMHO...
