How do you get the app version code at runtime? I have found many solutions to get the app version as a single integer. However I need the major.minor.patch version of the version code.

2The `versionCode` *is* "a single integer". It has never been in the "major.minor.patch" format. `versionName` *could* be in that format, but it does not have to be. There is no requirement for any developer of any Android app to use "major.minor.patch" for anything. – CommonsWare Jun 12 '15 at 10:42

That would mean to get the versionName that follows the semantic versioning principles.
Get the versionName:
packageManager.getPackageInfo(packageName(), PackageManager.GET_META_DATA)
.versionName; // throws NameNotFoundException
Parse the versionName:
// check versionName against ^\d+\.\d+\.\d+$
final String[] versionNames = versionName.split("\\.");
final Integer major = Integer.valueOf(versionNames[0]);
final Integer minor = Integer.valueOf(versionNames[1]);
final Integer patch = Integer.valueOf(versionNames[2]);
DO make sure to handle all possible errors.

The problem was actually that I didn't know that versionName was what I needed. – 7heViking Jun 12 '15 at 11:38

1I had to escape the dot to make this work, ie.: final String[] versionNames = versionName.split("\\."); – Stephan Henningsen Mar 14 '16 at 13:15

you get it by this way
PackageManager manager = context.getPackageManager();
PackageInfo info = manager.getPackageInfo(
context.getPackageName(), 0);
String version = info.versionName;
int code = info.versionCode;
