Question

in my android project all of my .java view files import the R file based on the name of the current package. When I change the name of my package name in the Android Manifest (dynamically, not refactoring via Eclipse or any other IDE), I need to the references of all my java files to point to the new R file that gets generated

I am making a build script via Ant, but I am not sure what the regular expression convention would look like

The strings that need to be replaced look like this:

import com.mysite.myapp.R;

ie.

import com.sushiroll.california.R

This is what I have in my ant build script

<replaceregexp file="src/*"
           match="import*.R"
           replace="import ${current.package}.R"
           byline="true">
        <fileset dir="src/.">
            <include name="*.java"/>
        </fileset>
</replaceregexp>

where I want to match all strings that say import and end in .R

and replace it with import $current.package}.R

how would I word that for ant regex? the match and replace that I wrote were just guesses

Answer 1

You need to group old package name chars before .R

if you know package name

    match="import com\.mysite\.myapp\.R;"

if you do now know package name, but be prepared to be failed for wrong imports if you import R from different packages

    match="import (.*).R;"

replace to

replace="import ${current.package}.R;"

and the

    <fileset dir="src">
        <include name="**/*.java"/>
    </fileset>
