Yea I caught that on my own. Here I went even further to convert the
version to string, and prevent a null pointer by using an empty string
that exists.
String versionNo = "";
PackageInfo pInfo = null;
try{
pInfo = getPackageManager().getPackageInfo
("com.yourpackagehere",PackageManager.GET_META_DATA);
} catch (NameNotFoundException e) {
pInfo = null;
}
if(pInfo != null)
versionNo = ""+pInfo.versionCode;
You also need some imports
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
