Question

I am trying to write the parameters to the managedQuery method in android and having trouble with the WHERE clause, here is what i wrote;

Cursor imageCursor;

// lots of other junk

String[] proj = {MediaStore.Images.Media.TITLE};

imageCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj, MediaStore.Images.Media.DATA = filename, proj, null );

“filename” is a string variable holding the path of an image, example /mnt/sdcard/pic05.png

I want it to return a cursor holding a record that is the same record for the pic05.png image and the cursor returned would hold the TITLE column information for this specific picture. How did i mess up the sql WHERE CLAUSE? I thought that my syntax must be wroing on the where clause

Answer 1

Add ‘ ‘ around filename. Try this

   Cursor imageCursor;

     // lots of other junk

       String[] proj = {MediaStore.Images.Media.TITLE};
    String selection = MediaStore.Images.Media.DATA + "='" + filename +"'";

     imageCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj, selection, null, null );
