How to insert "<<" text in TextView?

Question

I need to insert "<<" in android:text = "<<" but there are raise problem with:

Multiple annotations found at this line:
    - [I18N] Hardcoded string "<<", should use @string resource
    - The value of attribute "android:text" associated with an element type "Button" must not contain the '<' 
     character.

Can you tell me how can I insert << in xml file TextView text?

Answer 1

Try << instead of <<. You have to escape those characters because they influence your XML layout.
