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;
