User versionName value of AndroidManifest.xml in code

Question

The AndroidManifest.xml contains the version name of the application, something like

android:versionName="1.0" 

Now the question - is it somehow possible to access this version name in the source code, so that I can display it for example in an About Dialog?

Answer 1

If you use ADT and Eclipse:

String version = getPackageManager().getPackageInfo(getPackageName(), 0).versionName; 

If you use Gradle, there is an easier way, since it puts the data into BuildConfig for you:

String version = BuildConfig.VERSION_NAME; 

Answer 2

Konstantin's answer (above) is correct, but for what it's worth I found that I got a compiler error if I did not catch a NameNotFoundException , as follows:

import android.content.pm.PackageManager.NameNotFoundException; try {     String version = getPackageManager().getPackageInfo(getPackageName(), 0).versionName; } catch (NameNotFoundException e) {     Log.e("tag", e.getMessage()); }
