ckChangeLog - An Android Library to display a Change Log

Screenshot Screenshot

This library provides an easy way to display a change log in your app.


  • Displays changes since the last app update
  • Can display the complete change log history
  • Uses a simple XML file as source
  • Supports partial translations
  • Easily extendable to use something other than a dialog

  1. Create the master change log in res/xml/changelog_master.xml. Formatted like this:
<?xml version="1.0" encoding="utf-8"?>
    <release version="1.1" versioncode="11" >
        <change>Totally new and shiny version</change>
    <release version="1.0" versioncode="10" >
        <change>Fixed: A bug fix</change>
        <change>Some other changes I can't quite remember</change>
    <release version="0.1" versioncode="1">
        <change>First release</change>
  1. Create translations of this changelog_master.xml file in files named changelog.xml under language-specific versions of res/xml/, e.g. res/xml-de/changelog.xml.

  2. Display the change log dialog by putting the following code in your activity's onCreate() method:

ChangeLog cl = new ChangeLog(this);
if (cl.isFirstRun()) {

Include the library

The easiest way to add ckChangeLog to your project is via Gradle. Just add the following lines to your build.gradle:

dependencies {
    compile 'de.cketti.library.changelog:ckchangelog:1.2.2'

To tell Gradle where to find the library, make sure build.gradle also contains this:

repositories {

Customize labels

In order to change the labels of the dialog add the following items to your strings.xml:

  <string name="changelog_full_title">Change Log</string>
  <string name="changelog_title">What\'s New</string>
  <string name="changelog_ok_button">OK</string>
  <string name="changelog_show_full">More…</string>
