eclipse html5 - No grammar constraints(DTD or XML schema)detected for the document(Android)

element w3c (8)

I have the same problem as many here, but i DO HAVE xmlns:android and the xml=... tags. Still I have the same error. I don't wan't just click the ignore instead of warning in the settings so hence the question here posted.

The source is:

<?xml version="1.0" encoding="utf-8"?>
<GridLayout xmlns:android=""
    android:layout_height="match_parent" >


The error:

"No grammar constraints (DTD or XML schema) detected for the document. grid_layout_test2.xml /SomeProject/res/layout line 1 XML Problem"


You could also add

<!DOCTYPE androidXML>


<?xml version="1.0" encoding="utf-8" ?>

and then just right-click your project and select Validate

Move marked files outside project folder.( or Move the folder containint marked files.) Reflesh the project.(Select the project in Project explorer, ->) Move back files. Reflesh the project.

Solution For Eclipse:

add <!DOCTYPE something> to the begining of each problematic XML,

after the xml tag <?xml version="1.0" encoding="utf-8"?>

you can write anything for doctype, but basically it's supposed to be manifest, activity, etc. from what I understand

For me it was a Problem with character encoding and unix filemode running eclipse on Windows:

Just marked the complete code, cutted and pasted it back (in short: CtrlA-CtrlX-CtrlV) and everything was fine - no more "No grammar constraints..." warnings

simple way is first select all(ctrl+a) cut it (ctrl+x) than past, same error comes on most bottom do same process again and save it, angain do the above process, than your xml file is free from this type of error.

I retrieve a solution from a bug issue :

  1. Click Window > Preferences > XML > XML Files > Validation
  2. Change the setting 'validating files'>'No grammar specified' from warning to ignore.
  3. Re-validate your project. No more warnings now.

It works for me.

Be careful, my solution is a kind of "I do not understand so that I prefer to deactivate"...

In my case I solved this problem by this

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>

Android does not support OpenType (OTF), only TrueType (TTF), so your Molot.otf font probably will not work. I wrote both of those blog posts you link to in your opening sentence (the one is a pirated copy of the other), and they do not use Molot.otf.

(BTW, I somewhat repaired the formatting of that post -- AndroidGuys keeps changing WordPress hosts, and so my older posts are terribly broken in terms of formatting).

EDIT: As stated in the comments, Android DOES now support OTF.
