How to get the build/version number of your Android application?

Question

I need to figure out how to get or make a build number for my Android application. I need the build number to display in the UI.

Do I have to do something with AndroidManifest.xml?

Answer 1

If you're working the Gradle plugin/Android Studio, as of version 0.7.0, version code and version name are accessible statically in BuildConfig. Get sure you ship your app's package and not extra BuildConfig:

import com.yourpackage.BuildConfig;

...

int versionCode = BuildConfig.VERSION_CODE;

String versionName = BuildConfig.VERSION_NAME;

No Setting object required!

Also, secure to define them in your build.gradle file rather of the AndroidManifest.xml.

defaultConfig {

versionCode 1

versionName "1.0"

}
