How can you get the build/version number of your Android application? – Dev

The best answers to the question “How can you get the build/version number of your Android application?” in the category Dev.


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?



try {
    PackageInfo pInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), 0);
    String version = pInfo.versionName;
} catch (PackageManager.NameNotFoundException e) {

And you can get the version code by using this

int verCode = pInfo.versionCode;


If you’re using the Gradle plugin/Android Studio, as of version 0.7.0, version code and version name are available statically in BuildConfig. Make sure you import your app’s package, and not another BuildConfig:

import com.yourpackage.BuildConfig;
int versionCode = BuildConfig.VERSION_CODE;
String versionName = BuildConfig.VERSION_NAME;

No Context object needed!

Also make sure to specify them in your build.gradle file instead of the AndroidManifest.xml.

defaultConfig {
    versionCode 1
    versionName "1.0"


There are two parts you need:

  • android:versionCode
  • android:versionName

versionCode is a number, and every version of the app you submit to the market needs to have a higher number than the last.

VersionName is a string and can be anything you want it to be. This is where you define your app as “1.0” or “2.5” or “2 Alpha EXTREME!” or whatever.



val manager = this.packageManager
val info = manager.getPackageInfo(this.packageName, PackageManager.GET_ACTIVITIES)
toast("PackageName = " + info.packageName + "\nVersionCode = "
            + info.versionCode + "\nVersionName = "
            + info.versionName + "\nPermissions = " + info.permissions)


PackageManager manager = this.getPackageManager();
PackageInfo info = manager.getPackageInfo(this.getPackageName(), PackageManager.GET_ACTIVITIES);
     "PackageName = " + info.packageName + "\nVersionCode = "
       + info.versionCode + "\nVersionName = "
       + info.versionName + "\nPermissions = " + info.permissions, Toast.LENGTH_SHORT).show();


Slightly shorter version if you just want the version name.

    String versionName = context.getPackageManager()
    .getPackageInfo(context.getPackageName(), 0).versionName;
} catch (PackageManager.NameNotFoundException e) {
        return false;
