Error: Xml declaration should proceed all document content (auto generated java code in colors.xml)

Question

Xml declaration should proceed all document content

Suddenly I am getting this error in my android project and i have not made any changes , but yet this popped up ,with some auto generated java code.

have tried commenting the above , but thats not working so tried adding the following code to make it correct

<resources>
    <color name="colorPrimary">#3F51B5</color>
    <color name="colorPrimaryDark">#303F9F</color>
    <color name="colorAccent">#FF4081</color>
    <color name="your_color">#FFFFFF</color>
</resources>

still nothing happened.

Are you adding Java code to an XML file? That might be the issue. — Edric, Dec 08 '19 at 09:39

Yup - just as I've suspected, you _have_ entered Java code into an XML file. Simply remove the Java code to fix the issue. — Edric, Dec 08 '19 at 09:46

Because a space is created before the first line of code :

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

This is because XML files should only contain valid XML markup and not contain Java code. Change the contents of your XML file to exclude the Java code by either commenting it out with  or by deleting the Java code altogether.

commenting was not working ... deletion worked ... thanks – Ankita Basu Dec 08 '19 at 09:48
@AnkitaBasu Just curious, but how did you end up pasting Java code into an XML file in the first place? – Edric Dec 08 '19 at 09:48
@AnkitaBasu, Commenting should also work. ` #3F51B5 #303F9F #FF4081 #FFFFFF ` – Md. Asaduzzaman Dec 08 '19 at 09:50
