If you want to use it on XML content then add the below line in your Gradle file  applicationVariants all   variant - gt      variant resValue  quot string quot    quot versionName quot   variant versionName    And then use it on your XML content like this   lt TextView         android gravity  quot center horizontal quot          android layout width  quot match parent quot          android layout height  quot wrap content quot          android text  quot  string versionName quot    gt

No  you don t need to do anything with AndroidManifest xml Basically  your app s version name and version code is inside the app level Gradle file  under defaultConfig tag  defaultConfig      versionCode 1    versionName  quot 1 0 quot     Note  When you wish to upload an app to the playstore  it can give any name as the version name  but the version code have to be different than the current version code if this app is already in the play store  Simply use the following code snippet to get the version code  amp  version name from anywhere in your app  try       PackageInfo pInfo     context getPackageManager   getPackageInfo context getPackageName    0       String version   pInfo versionName      int verCode   pInfo versionCode    catch  PackageManager NameNotFoundException e        e printStackTrace

Using Gradle and BuildConfig Getting the VERSION NAME from BuildConfig BuildConfig VERSION NAME  Yep  it s that easy now  Is it returning an empty string for VERSION NAME  If you re getting an empty string for BuildConfig VERSION NAME then read on  I kept getting an empty string for BuildConfig VERSION NAME  because I wasn t setting the versionName in my Grade build file  I migrated from Ant to Gradle   So  here are instructions for ensuring you re setting your VERSION NAME via Gradle  File build gradle def versionMajor   3 def versionMinor   0 def versionPatch   0 def versionBuild   0    Bump for dogfood builds  public betas  etc   android      defaultConfig       versionCode versionMajor   10000   versionMinor   1000   versionPatch   100   versionBuild      versionName  quot   versionMajor    versionMinor    versionPatch  quot          Note  This is from the masterful Jake Wharton  Removing versionName and versionCode from AndroidManifest xml And since you ve set the versionName and versionCode in the build gradle file now  you can also remove them from your AndroidManifest xml file  if they are there

There are some ways to get versionCode and versionName programmatically   Get version from PackageManager  This is the best way for most cases   try        String versionName   packageManager getPackageInfo packageName  0  versionName       int versionCode   packageManager getPackageInfo packageName  0  versionCode     catch  PackageManager NameNotFoundException e         e printStackTrace         Get it from generated BuildConfig java  But notice  that if you ll access this values in library it will return library version  not apps one  that uses this library  So use only in non-library projects   String versionName   BuildConfig VERSION NAME   int versionCode   BuildConfig VERSION CODE      There are some details  except of using second way in library project  In new Android Gradle plugin  3 0 0   some functionalities removed  So  for now  i e  setting different version for different flavors not working correct  Incorrect way  applicationVariants all   variant - gt      println  variantApp      variant getName         def versionCode    SOME GENERATED VALUE IE TIMESTAMP      def versionName    SOME GENERATED VALUE IE TIMESTAMP       variant mergedFlavor versionCode   versionCode     variant mergedFlavor versionName   versionName    Code above will correctly set values in BuildConfig  but from PackageManager you ll receive 0 and null if you didn t set version in default configuration  So your app will have 0 version code on device  There is a workaround - set version for output apk file manually  applicationVariants all   variant - gt      println  variantApp      variant getName         def versionCode    SOME GENERATED VALUE IE TIMESTAMP      def versionName    SOME GENERATED VALUE IE TIMESTAMP       variant outputs all   output - gt          output versionCodeOverride   versionCode         output versionNameOverride   versionName

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  quot 1 0 quot  or  quot 2 5 quot  or  quot 2 Alpha EXTREME  quot  or whatever  Example   Kotlin  val manager   this packageManager val info   manager getPackageInfo this packageName  PackageManager GET ACTIVITIES  toast  quot PackageName    quot    info packageName    quot  nVersionCode    quot                info versionCode    quot  nVersionName    quot                info versionName    quot  nPermissions    quot    info permissions   Java  PackageManager manager   this getPackageManager    PackageInfo info   manager getPackageInfo this getPackageName    PackageManager GET ACTIVITIES   Toast makeText this        quot PackageName    quot    info packageName    quot  nVersionCode    quot           info versionCode    quot  nVersionName    quot           info versionName    quot  nPermissions    quot    info permissions  Toast LENGTH SHORT  show

Here is a clean solution  based on the solution of scottyab  edited by Xavi   It shows how to get the context first  if it s not provided by your method  Furthermore  it uses multiple lines instead of calling multiple methods per line  This makes it easier when you have to debug your application  Context context   getApplicationContext       or activity getApplicationContext   PackageManager packageManager   context getPackageManager    String packageName   context getPackageName     String myVersionName    quot not available quot      initialize String  try       myVersionName   packageManager getPackageInfo packageName  0  versionName    catch  PackageManager NameNotFoundException e        e printStackTrace       Now that you received the version name in the String myVersionName  you can set it to a TextView or whatever you like      Set the version name to a TextView TextView tvVersionName    TextView  findViewById R id tv versionName   tvVersionName setText myVersionName
