Android build number names

List of Android version names

Android versions up to Android 10! 10 got, additionally to their nummeric version number, a code-name, which was assigned by Google. Like the naming of Ubuntu versions (names of animals with an adjective [1] ), Android version names were names of, mostly american, sweets, where the first letter was in alphabetical order.

The assignment of numeric and textual version names are not always consistent. Android 4.0 and Android 4.1, for example, have different version names, but Android 5.0, 5.1 and 5.1.1 share the same version name.

Starting with Android 10! 10, Android versions do not get a codename anymore. Since then, the Android versions will be released with their version number only. [2] [3] [4] [5]

The table in this article lists all the different versions of Android, starting with the earliest Application Programming Interface (API) level to the latest API level. Thus the list is from the oldest Android versions to the latest.

Android Versions by Name, Number, Availability and API Level

Each version of Android is given a code name. The code name is traditionally the name of a dessert, cake or sweet, e.g, Gingerbread, Froyo, Jelly Bean, etc. — as the sugar laden picture below shows. The table that follows lists the code names, version numbers, first release date and Application Programming Interface (API) versions, along with the equivalent Software Development Kit (SDK) constants (Build.VERSION_CODES). The Android version number on a device is normally found in the settings. Select Settings, then About Phone or About Device and look at the Firmware Version or Android Version entry.

Oreo	8.1.0	December 2017	27	O_MR1

The above table was derived from the following sources (note that some release dates are derived from the Android developers documentation, the actual SDK availability may have been a little earlier, see the Wikipedia article):

When programming an App the API level is used to determine whether specific Android features are present or not. The API level can be read in versions prior to Donut (Cupcake, 1.1 and 1.0) using:

int APILevel = Integer.parseInt(Build.VERSION.SDK);

And from Donut onwards using:

int APILevel = Build.VERSION.SDK_INT;

(Build.VERSION.SDK is deprecated, i.e. it will be removed from the API at some future release).

When using functionality from a later API, but the App needs to support earlier Android versions, wrap the newer functionality in a separate class. Then check the API level before instantiating the class to prevent a VerifyError exception from occurring. See the article Support Multiple API Versions in Android.

Versioning with Flutter

Please note: This is my first article since I left university. So please be patient.
2nd note: My Java/Kotlin/Swift/Dart is much better than my English 😉

Does it bother you to increase the version in the Android as well as in the iOS part again and again? You can be helped.

Every time you want to create a new version you have to increase the build number in Android as well as in iOS: You have to modify the app/build.gradle file and the Info.plist file.

Would it be nice to have just one place to do that?

If you create a new Flutter project the pubspec.yaml file has a version property like this:

Flutter uses this value to set the version in both Android and iOS for you. You only need to call flutter run or flutter build or press the play button in IntelliJ / Android Studio / the IDE of your choice.

The Format

Flutter expects an exact format of the version property.

It has two parts separated by a + . The first part is the build name ( versionName Android / CFBundleShortVersionString iOS) and the second part is the build number ( versionCode Android / CFBundleVersion iOS).

The build name can have up to 3 integers separated by dots. The build number is just one integer.

How to modify them?

You can still edit the pubspec.yaml file by hand but sometimes you need a way to modify them automatically for example when your CI builds a new version.

To change the version automatically, you have two options —-build-name and —build-number . These two options are options of the flutter build command:

I use Fastlane to do my CI builds. My fastfile looks like this:

How to update an old Flutter project?

You can also do the above with an old flutter project, but you need to make some changes.

Flutter Part

All you have to do is to add the version property to your pubspec.yaml file. It should look like this:

Android Part

Every time you call flutter run or flutter build Flutter updates the local.properties file. You only need to use the values in your app/build.gradle file.

To do that modify you app/build.gradle file that it looks like this:

Read the values from the local.properties file (lines 14 till 22) and use them (line 39 and 40).

iOS Part

flutter run and flutter build updates the Generated.xcconfig file too, just use its values.

Change the CFBundleShortVersionString value to $(FLUTTER_BUILD_NAME) (line 18) and the CFBundleVersion value to $(FLUTTER_BUILD_NUMBER) (line 21).

Open the project in Xcode, select the Build Settings tab of the Runner target and search for versioning . Change the value of Current Project Version to $(FLUTTER_BUILD_NUMBER) .

Bonus

T̶h̶e̶ ̶f̶o̶l̶l̶o̶w̶i̶n̶g̶ ̶d̶e̶p̶e̶n̶d̶s̶ ̶o̶n̶ ̶#̶1̶6̶9̶3̶4̶.̶ ̶C̶u̶r̶r̶e̶n̶t̶l̶y̶,̶ ̶i̶t̶ ̶i̶s̶n̶’̶t̶ ̶m̶e̶r̶g̶e̶d̶,̶ ̶s̶o̶ ̶y̶o̶u̶ ̶h̶a̶v̶e̶ ̶t̶o̶ ̶w̶a̶i̶t̶ ̶a̶ ̶l̶i̶t̶t̶l̶e̶ ̶b̶i̶t̶.̶ ̶B̶u̶t̶ ̶a̶s̶ ̶w̶e̶ ̶s̶a̶y̶ ̶i̶n̶ ̶G̶e̶r̶m̶a̶n̶y̶̶…

It was never merged, but you can use the package_info plugin instead.

Now that our Flutter project knows the version it would be nice to access it to show it somewhere, in an about dialog for example.

With #16934 Flutter generates a lib/build_config.g.dart file which looks like this:

You can now easily use it to show the version or to do other fancy things depending on the build, for example, if it is a debug build or which flavor was build.
