title: Coverity - Explicit null dereferenced (FORWARD_NULL) in contentResolver.delete()
body: <p>Deleting all the rows from ContentProvider using delete() statement gives the Coverity error.<br></p>
  
  <p><strong>Explicit null dereferenced (FORWARD_NULL)</strong><br>
  <strong>Passing null pointer selection to delete, which dereferences it.</strong></p>
  
  <pre><code>String selection = null;
  String[] selectionArgs = null;
  
  mContentResolver.delete(MyContentProvider.MY_CONTENT_URI, selection, selectionArgs);
  </code></pre>
  
  <p>Is there any way to fix this Coverity issue ??</p>
