HONEYCOMB

public static final int HONEYCOMB

Released publicly as Android 3.0 in February 2011.

Applications targeting this or a later release will get these new changes in behavior:

The default theme for applications is now dark holographic: R.style.Theme_Holo.
On large screen devices that do not have a physical menu button, the soft (compatibility) menu is disabled.
The activity lifecycle has changed slightly as per Activity.
An application will crash if it does not call through to the super implementation of its Activity.onPause() method.
When an application requires a permission to access one of its components (activity, receiver, service, provider), this permission is no longer enforced when the application wants to access its own component. This means it can require a permission on a component that it does not itself hold and still access that component.
Context.getSharedPreferences() will not automatically reload the preferences if they have changed on storage, unless Context.MODE_MULTI_PROCESS is used.
ViewGroup.setMotionEventSplittingEnabled(boolean) will default to true.
WindowManager.LayoutParams.FLAG_SPLIT_TOUCH is enabled by default on windows.
PopupWindow.isSplitTouchEnabled() will return true by default.
GridView and ListView will use View.setActivated for selected items if they do not implement Checkable.
Scroller will be constructed with "flywheel" behavior enabled by default.

Constant Value: 11 (0x0000000b)

HONEYCOMB_MR1

public static final int HONEYCOMB_MR1

H MR1.

Released publicly as Android 3.1 in May 2011.

Constant Value: 12 (0x0000000c)

HONEYCOMB_MR2

public static final int HONEYCOMB_MR2

H MR2.

Released publicly as Android 3.2 in July 2011.

Update to Honeycomb MR1 to support 7 inch tablets, improve screen compatibility mode, etc.

As of this version, applications that don't say whether they support XLARGE screens will be assumed to do so only if they target HONEYCOMB or later; it had been GINGERBREAD or later. Applications that don't support a screen size at least as large as the current screen will provide the user with a UI to switch them in to screen size compatibility mode.

This version introduces new screen size resource qualifiers based on the screen size in dp: see Configuration.screenWidthDp, Configuration.screenHeightDp, and Configuration.smallestScreenWidthDp. Supplying these in <supports-screens> as per ApplicationInfo.requiresSmallestWidthDp, ApplicationInfo.compatibleWidthLimitDp, and ApplicationInfo.largestWidthLimitDp is preferred over the older screen size buckets and for older devices the appropriate buckets will be inferred from them.

Applications targeting this or a later release will get these new changes in behavior:

New PackageManager.FEATURE_SCREEN_PORTRAIT and PackageManager.FEATURE_SCREEN_LANDSCAPE features were introduced in this release. Applications that target previous platform versions are assumed to require both portrait and landscape support in the device; when targeting Honeycomb MR1 or greater the application is responsible for specifying any specific orientation it requires.
AsyncTask will use the serial executor by default when calling AsyncTask.execute(Params...).
ActivityInfo.configChanges will have the ActivityInfo.CONFIG_SCREEN_SIZE and ActivityInfo.CONFIG_SMALLEST_SCREEN_SIZE bits set; these need to be cleared for older applications because some developers have done absolute comparisons against this value instead of correctly masking the bits they are interested in.

Constant Value: 13 (0x0000000d)

ICE_CREAM_SANDWICH

public static final int ICE_CREAM_SANDWICH

Released publicly as Android 4.0 in October 2011.

Applications targeting this or a later release will get these new changes in behavior:

For devices without a dedicated menu key, the software compatibility menu key will not be shown even on phones. By targeting Ice Cream Sandwich or later, your UI must always have its own menu UI affordance if needed, on both tablets and phones. The ActionBar will take care of this for you.
2d drawing hardware acceleration is now turned on by default. You can use android:hardwareAccelerated to turn it off if needed, although this is strongly discouraged since it will result in poor performance on larger screen devices.
The default theme for applications is now the "device default" theme: R.style.Theme_DeviceDefault. This may be the holo dark theme or a different dark theme defined by the specific device. The R.style.Theme_Holo family must not be modified for a device to be considered compatible. Applications that explicitly request a theme from the Holo family will be guaranteed that these themes will not change character within the same platform version. Applications that wish to blend in with the device should use a theme from the R.style.Theme_DeviceDefault family.
Managed cursors can now throw an exception if you directly close the cursor yourself without stopping the management of it; previously failures would be silently ignored.
The fadingEdge attribute on views will be ignored (fading edges is no longer a standard part of the UI). A new requiresFadingEdge attribute allows applications to still force fading edges on for special cases.
Context.bindService() will not automatically add in Context.BIND_WAIVE_PRIORITY.
App Widgets will have standard padding automatically added around them, rather than relying on the padding being baked into the widget itself.
An exception will be thrown if you try to change the type of a window after it has been added to the window manager. Previously this would result in random incorrect behavior.
AnimationSet will parse out the duration, fillBefore, fillAfter, repeatMode, and startOffset XML attributes that are defined.
ActionBar.setHomeButtonEnabled() is false by default.

Constant Value: 14 (0x0000000e)

ICE_CREAM_SANDWICH_MR1

public static final int ICE_CREAM_SANDWICH_MR1

I MR1.

Released publicly as Android 4.03 in December 2011.

Constant Value: 15 (0x0000000f)

JELLY_BEAN

public static final int JELLY_BEAN

Released publicly as Android 4.1 in July 2012.

Applications targeting this or a later release will get these new changes in behavior:

You must explicitly request the Manifest.permission.READ_CALL_LOG and/or Manifest.permission.WRITE_CALL_LOG permissions; access to the call log is no longer implicitly provided through Manifest.permission.READ_CONTACTS and Manifest.permission.WRITE_CONTACTS.
RemoteViews will throw an exception if setting an onClick handler for views being generated by a RemoteViewsService for a collection container; previously this just resulted in a warning log message.
New ActionBar policy for embedded tabs: embedded tabs are now always stacked in the action bar when in portrait mode, regardless of the size of the screen.
WebSettings.setAllowFileAccessFromFileURLs and WebSettings.setAllowUniversalAccessFromFileURLs default to false.
Calls to PackageManager.setComponentEnabledSetting will now throw an IllegalArgumentException if the given component class name does not exist in the application's manifest.
NfcAdapter.setNdefPushMessage, NfcAdapter.setNdefPushMessageCallback and NfcAdapter.setOnNdefPushCompleteCallback will throw IllegalStateException if called after the Activity has been destroyed.
Accessibility services must require the new Manifest.permission.BIND_ACCESSIBILITY_SERVICE permission or they will not be available for use.
AccessibilityServiceInfo.FLAG_INCLUDE_NOT_IMPORTANT_VIEWS must be set for unimportant views to be included in queries.

Constant Value: 16 (0x00000010)

JELLY_BEAN_MR1

public static final int JELLY_BEAN_MR1

J MR1.

Released publicly as Android 4.2 in November 2012.

Applications targeting this or a later release will get these new changes in behavior:

Content Providers: The default value of android:exported is now false. See the android:exported section in the provider documentation for more details.
View.getLayoutDirection() can return different values than View.LAYOUT_DIRECTION_LTR based on the locale etc.
WebView.addJavascriptInterface requires explicit annotations on methods for them to be accessible from Javascript.

Constant Value: 17 (0x00000011)

JELLY_BEAN_MR2

public static final int JELLY_BEAN_MR2

J MR2.

Released publicly as Android 4.3 in July 2013.

Constant Value: 18 (0x00000012)

KITKAT

public static final int KITKAT

Released publicly as Android 4.4 in October 2013.

Applications targeting this or a later release will get these new changes in behavior. For more information about this release, see the Android KitKat overview.

The default result of PreferenceActivity.isValueFragment becomes false instead of true.
In WebView, apps targeting earlier versions will have JS URLs evaluated directly and any result of the evaluation will not replace the current page content. Apps targetting KITKAT or later that load a JS URL will have the result of that URL replace the content of the current page
AlarmManager.set becomes interpreted as an inexact value, to give the system more flexibility in scheduling alarms.
Context.getSharedPreferences no longer allows a null name.
RelativeLayout changes to compute wrapped content margins correctly.
ActionBar's window content overlay is allowed to be drawn.
The Manifest.permission.READ_EXTERNAL_STORAGE permission is now always enforced.
Access to package-specific external storage directories belonging to the calling app no longer requires the Manifest.permission.READ_EXTERNAL_STORAGE or Manifest.permission.WRITE_EXTERNAL_STORAGE permissions.

Notification.Builder will not have the colors of their various notification elements adjusted to better match the new material design look.
Message will validate that a message is not currently in use when it is recycled.
Hardware accelerated drawing in windows will be enabled automatically in most places.
Spinner throws an exception if attaching an adapter with more than one item type.
If the app is a launcher, the launcher will be available to the user even when they are using corporate profiles (which requires that the app use LauncherApps to correctly populate its apps UI).
Calling Service.stopForeground with removeNotification false will modify the still posted notification so that it is no longer forced to be ongoing.
A DreamService must require the Manifest.permission.BIND_DREAM_SERVICE permission to be usable.

Constant Value: 21 (0x00000015)

AlarmManager.setTimeZone will fail if the given timezone is non-Olson.
Activity transitions will only return shared elements mapped in the returned view hierarchy back to the calling activity.
