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?

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;

That's too many "getPackage"s for a single line of code... O_O – Cephron Apr 12 '11 at 20:06

Great! But is there a way to get the value from an xml file (especially to use it as `android:summary` of a `Preference` node)? – Ethan Leroy Jul 31 '12 at 20:31

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());
}
