Bundle - is key case sensitive?

Question

I\'m using Bundle to send data.

Bundle b = new Bundle();
b.putDouble(\"x\", this.Location.X);
b.putDouble(\"y\", this.Location.Y);

Is key case

Answer 1

Bundle and other Key Mapping mechanism are case sensitive.

Answer 2

Looks like a simple Map, so probably. Why don't you test it?

EDIT: The key is a String. "x".equals("X") == false
