like this?
String string = "Congrats {{customer}}";
String newValue = string.replace("{{customer}}", "xyz");
// 'string' remains the same..but 'newValue' has the replacement.
System.out.println(newValue);

what kind of error do you get? Note that the string is only replaced on the 'newValue' variable..not on the 'string' variable itself.
Use the replace method on the String object to do this. Since String is immutable it will return a new object instance with the replaced text. Example:
String myString = "Congrats {{customer}}";
myString = myString.replace("{{customer}}","John");
System.out.println(myString);
Output:
Congrats John
See also the String javadoc for many more useful utility methods.

That looks like a mustache template.
See https://github.com/spullara/mustache.java
Typically, in your case:
HashMap<String, Object> scopes = new HashMap<String, Object>();
scopes.put("customer", "xyz");
Writer writer = new OutputStreamWriter(System.out);
MustacheFactory mf = new DefaultMustacheFactory();
Mustache mustache = mf.compile(new StringReader("Congrats {{customer}}, you become the potential winner of auction"), "example");
mustache.execute(writer, scopes);
writer.flush();

Using resources, you can use method like this:
String customer = "Joe Doe";
String textHello;
textHello = String.format(getString(R.string.hello_customer), customer);
where hello_customer is your string resorce strings.xml.
strings.xml part should look like this:
<string name="hello_customer">Congrats %1$s, you become the potential winner of auction with \"xyz\".</string>
