Versioning Android apps

build.gradle

apply plugin: 'com.android.application'

ext.versionMajor = 1
ext.versionMinor = 2
ext.versionPatch = 3
ext.versionClassifier = null
ext.isSnapshot = true
ext.minimumSdkVersion = 19

android {
	compileSdkVersion 27
	buildToolsVersion "27.0.0"

	defaultConfig {
		applicationId "com.sample"
		targetSdkVersion 27
		minSdkVersion project.ext.minimumSdkVersion
		versionCode generateVersionCode() // 190010203
		versionName generateVersionName() // 1.2.3-SNAPSHOT
	}
}

private Integer generateVersionCode() {
	return ext.minimumSdkVersion * 10000000 + ext.versionMajor * 10000 + ext.versionMinor * 100 + ext.versionPatch
}

private String generateVersionName() {
	String versionName = "${ext.versionMajor}.${ext.versionMinor}.${ext.versionPatch}"
	if (ext.versionClassifier == null && ext.isSnapshot) {

	}

	if (ext.versionClassifier != null) {
		versionName += "-" + ext.versionClassifier

Hi Maxi

For example, when the application version name is 3.1.0, the version code for a minimum API level 4 APK would be something like 040030100. The first two digits are reserved for the minimum API Level (4 in this case), the third digit is for either screen sizes or GL texture formats (not used in this example, so a 0 is assigned), and the last six digits are for the application’s version name (3.1.0).

I've got my minimum screensize set to 600dp for tablets, how can I setup the third digit — and my actual question is how are you 'changing' this number so I can plan accordingly.

Thanks!!

Hi what does ext means here? How does it helps?

ext.versionMajor = 1
ext.versionMinor = 2
ext.versionPatch = 3
ext.versionClassifier = null
ext.isSnapshot = true
ext.minimumSdkVersion = 15

can you help me on how to integrate this gradle file in CI/CD to pass incremental values automatically to these variables for every build
ext.versionMajor = 1
ext.versionMinor = 2
ext.versionPatch = 3

Hi

what will be the max limit for
private Integer generateVersionCode() {
return ext.minimumSdkVersion * 10000000 + ext.versionMajor * 10000 + ext.versionMinor * 100 + ext.versionPatch
}

this
when app version is 9999.9999.9999 is present

will this work?

Hi. This is explained here: https://medium.com/dipien/versioning-android-apps-d6ec171cfd82
The maximum supported version will be 99.99.99
