I thought the " @ " only concerned the id when you write for example : id="@+id/widget24", but actually it appears almost everywhere like : android:text="@string/table_layout_1_star" or, android:icon="@drawable/icon".
Could someone help me, i don't get the meaning of this thing.

thx

Someone else might have a more precise definition.
But the way I see it, it's put at the beginning of an XML entry to say "This is not an ordinary string, this is actually pointing to a file/memory address/ID/etc." to whatever is reading it.

I just want to know basically the meaning of @, and what you're saying seems to be true now that i think about it.
thank you.

Hello LW,

using the @ like this:

makes it a "relative"-Pointer. What means that you are pointing to another resource within this project
