I need to display the app's build version in my settings page.

So how can i get the versionCode and versionName from AndroidManifest.xml file programmatically.

Or

Is there any way to get the build version programmatically in xamarin.forms.

Answer 1

For version name:

Application.Context.ApplicationContext.PackageManager.GetPackageInfo(Application.Context.ApplicationContext.PackageName, 0).VersionName 

For version code:

Application.Context.ApplicationContext.PackageManager.GetPackageInfo(Application.Context.ApplicationContext.PackageName, 0).VersionCode

With a Dependency service:

For iOS:

using Foundation;  [assembly: Xamarin.Forms.Dependency(typeof(Screen_iOS))]  namespace XXX.iOS {     public class Screen_iOS : IScreen     {          public string Version         {             get             {                 NSObject ver = NSBundle.MainBundle.InfoDictionary["CFBundleShortVersionString"];                 return ver.ToString();             }         }      } } 

For Android:

using Xamarin.Forms;  [assembly: Dependency(typeof(ScreenAndroid))]  namespace XXX.Droid {     class ScreenAndroid : Java.Lang.Object, IScreen     {          public string Version         {             get             {                 var context = Forms.Context;                 return context.PackageManager.GetPackageInfo(context.PackageName, 0).VersionName;             }         }      } } 

And the interface:

interface IScreen {     string Version { get; } }
