Modify a XML template for an Android app

I just got an android app producing PDFs of Model releases. Thing is the release isn't great so i modified the template to add values and modify the text. Everything went great till i thought "why would i manually insert the date if it can be done automatically ?" I looked up some codes here but, as i just understand the basics of programing, it didn't work. Anyone can give me a bit of code to insert the current date automatically at the end of my paragraph? Here is the template if it can help :

<?xml version="1.0" encoding="utf-8"?>
<Agreement>
  <Title>Adult Model Release Contract</Title>
  <Description>Model release form for an     adult</Description>
  <Version>1</Version>
  <Variables>
    <Variable title="fullname" type="text">Model's Full     Legal Name</Variable>
    <Variable title="email" type="text">E-mail </Variable>
    <Variable title="adress" type="text">Adress</Variable>
    <Variable title="phone" type="number">Phone</Variable>
    <Variable title="social" type="text">Social     Network</Variable>
    <Logo bottom="690" left="40" width="175"/>
  </Variables>
  <Text>
    <Paragraph style="bold" spacing="80">Model     Release</Paragraph>
    <Paragraph>%fullname% (the “Model”),blah blah blah ... </Paragraph etc ...
