Coverity - Explicit null dereferenced (FORWARD_NULL) in contentResolver.delete()

Question

Deleting all the rows from ContentProvider using delete() statement gives the Coverity error.

Explicit null dereferenced (FORWARD_NULL)
Passing null pointer selection to delete, which dereferences it.

String selection = null;
String[] selectionArgs = null;

mContentResolver.delete(MyContentProvider.MY_CONTENT_URI, selection, selectionArgs);

Is there any way to fix this Coverity issue ??

Show us your `ContentProvider.delete` code and full logcat please :) — zozelfelfo, Oct 15 '14 at 07:04
@zozelfelfo This is not build error. Statement works fine and deletes all the rows as expected when executed. This error is shown in the Coverity static analysis tool. — Vijay C, Oct 15 '14 at 09:28

According to your code the issue seems right - you forward "null"... Can you post the code of your ContentResolver Implementation?

To remove the warning you may try to use:

String selection = "";
String[] selectionArgs = new String[0];

As you may see in the source code the selection (at least) for logging is set to:

selection != null ? selection : "",
