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());
}
