static val HONEYCOMB: Int

H.

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: android.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 android.app.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 android.content.Context#MODE_MULTI_PROCESS is used.
• android.view.ViewGroup#setMotionEventSplittingEnabled will default to true.
• android.view.WindowManager.LayoutParams#FLAG_SPLIT_TOUCH is enabled by default on windows.

• android.widget.Scroller will be constructed with "flywheel" behavior enabled by default.

Value: 11

HONEYCOMB_MR1

static val HONEYCOMB_MR1: Int

H MR1.

Released publicly as Android 3.1 in May 2011.

Value: 12

HONEYCOMB_MR2

static val HONEYCOMB_MR2: Int

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 android.content.res.Configuration#screenWidthDp, android.content.res.Configuration#screenHeightDp, and android.content.res.Configuration#smallestScreenWidthDp. Supplying these in <supports-screens> as per android.content.pm.ApplicationInfo#requiresSmallestWidthDp, android.content.pm.ApplicationInfo#compatibleWidthLimitDp, and android.content.pm.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 android.content.pm.PackageManager#FEATURE_SCREEN_PORTRAIT and android.content.pm.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.

• android.os.AsyncTask will use the serial executor by default when calling android.os.AsyncTask#execute.

• ActivityInfo.configChanges will have the android.content.pm.ActivityInfo#CONFIG_SCREEN_SIZE and android.content.pm.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.

Value: 13

ICE_CREAM_SANDWICH

static val ICE_CREAM_SANDWICH: Int

I.

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: android.R.style#Theme_DeviceDefault. This may be the holo dark theme or a different dark theme defined by the specific device. The android.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 android.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.
• android.content.Context#bindService will not automatically add in android.content.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.
• android.view.animation.AnimationSet will parse out the duration, fillBefore, fillAfter, repeatMode, and startOffset XML attributes that are defined.
• ActionBar.setHomeButtonEnabled() is false by default.

Value: 14

Released publicly as Android 4.03 in December 2011.

Value: 15

JELLY_BEAN

static val JELLY_BEAN: Int

J.

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 android.Manifest.permission#READ_CALL_LOG and/or android.Manifest.permission#WRITE_CALL_LOG permissions; access to the call log is no longer implicitly provided through android.Manifest.permission#READ_CONTACTS and android.Manifest.permission#WRITE_CONTACTS.
• android.widget.RemoteViews will throw an exception if setting an onClick handler for views being generated by a android.widget.RemoteViewsService for a collection container; previously this just resulted in a warning log message.
• New android.app.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 android.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.

J MR1.

Released publicly as Android 4.2 in November 2012.

• The default result of PreferenceActivity.isValueFragment becomes false instead of true.
• In android.webkit.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

• Notification.Builder will not have the colors of their various notification elements adjusted to better match the new material design look.
• android.os.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.
• android.widget.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 android.content.pm.LauncherApps to correctly populate its apps UI).
• Calling android.app.Service#stopForeground with removeNotification false will modify the still posted notification so that it is no longer forced to be ongoing.
• A android.service.dreams.DreamService must require the android.Manifest.permission#BIND_DREAM_SERVICE permission to be usable.
