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

Use:

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

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"}

Slightly shorter version if you just want the version name.

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