How to increment build numbers for iOS and Android 👀

Hello, I am more of a programmer than a content writer. In this tutorial, ‘am gonna put some simple and easy tricks I have learned so far.

Let’s get this started.

Increment Build Number/Version Code Automatically

This is purely based on the number of git commits. I liked it.

iOS:

• Go to your project Target, on the right side you will see Build Phases.
• Tap on the Build phases Tab.
• Tap on the + icon to add your script to increment the build number automatically.

It’s good to have the name of the script, I titled it as increment-build-script. sh.

#Update build number with number of git commits if in release mode
if [ ${CONFIGURATION} == "Release" ]; then
buildNumber=$(git rev-list HEAD | wc -l | tr -d ' ')
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "${PROJECT_DIR}/${INFOPLIST_FILE}"
fi;

Android:

The following snippet should be placed in build.Gradle(project) level. It will check the commit number of your master branch and change

ext {
    buildToolsVersion = "28.0.3"
    minSdkVersion = 19
    compileSdkVersion = 28
    targetSdkVersion = 28
    supportLibVersion = "28.0.0"
    googlePlayServicesVersion = "16.0.0"
    getVersionCode = { ->
            try {
                def stdout = new ByteArrayOutputStream()
                exec {
                commandLine 'git', 'rev-list', '--count', 'master'
                    standardOutput = stdout
                }
                return Integer.parseInt(stdout.toString().trim())
            }
            catch (ignored) {
                return -1;
            }
        }}

just call this getVersionCode in your app-level build. gradle file to get the dynamic version code.

defaultConfig {
    applicationId "com.example.app"
    minSdkVersion rootProject.ext.minSdkVersion
    targetSdkVersion rootProject.ext.targetSdkVersion
    versionCode rootProject.ext.getVersionCode()
    versionName "4.0"
    multiDexEnabled true
}
