int DONUT

2009年9月：Android 1.6。

面向此版本或更高版本的应用程序将获得这些行为的新变化：

• They must explicitly request the WRITE_EXTERNAL_STORAGE permission to be able to modify the contents of the SD card. (Apps targeting earlier versions will always request the permission.)

• They are assumed to support different screen densities and sizes. (Apps targeting earlier versions are assumed to only support medium density normal size screens unless otherwise indicated). They can still explicitly specify screen support either way with the supports-screens manifest tag.

HONEYCOMB

int HONEYCOMB

2011年2月：Android 3.0。

面向此版本或更高版本的应用程序将获得这些行为的新变化：

• The default theme for applications is now dark holographic: 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 MODE_MULTI_PROCESS is used.
• setMotionEventSplittingEnabled(boolean) will default to true.
• FLAG_SPLIT_TOUCH is enabled by default on windows.
• PopupWindow.isSplitTouchEnabled() will return true by default.

HONEYCOMB_MR2

int HONEYCOMB_MR2

2011年6月：Android 3.2。

更新至Honeycomb MR1以支持7英寸平板电脑，改进屏幕兼容模式等。

从这个版本开始，没有说他们是否支持XLARGE屏幕的应用程序只会在HONEYCOMB或更高版本HONEYCOMB ; 它已经是GINGERBREAD或更高版本。 不支持至少与当前屏幕一样大的屏幕尺寸的应用程序将为用户提供UI以将其切换到屏幕尺寸兼容模式。

该版本引入了基于在DP屏幕尺寸新的屏幕大小的资源预选赛：看screenWidthDp ， screenHeightDp ，并smallestScreenWidthDp 。 在<载体的筛选>供给这些按requiresSmallestWidthDp ， compatibleWidthLimitDp和largestWidthLimitDp优于较老的画面尺寸的桶和用于旧设备的适当的存储桶将从他们推断。

面向此版本或更高版本的应用程序将获得这些行为的新变化：

• 此版本中引入了新的FEATURE_SCREEN_PORTRAIT和FEATURE_SCREEN_LANDSCAPE功能。 假定针对以前平台版本的应用程序需要在设备中支持纵向和横向支持; 当针对Honeycomb MR1或更高版本时，应用程序负责指定它需要的任何特定方向。

• 当调用 execute(Params...)时，默认情况下 AsyncTask将使用串行执行 execute(Params...) 。

• ActivityInfo.configChanges将设置CONFIG_SCREEN_SIZE和CONFIG_SMALLEST_SCREEN_SIZE位; 这些需要被旧的应用程序清除，因为一些开发人员已经对这个值进行了绝对比较，而不是正确地屏蔽他们感兴趣的位。

常量值：13（0x0000000d）

ICE_CREAM_SANDWICH

int ICE_CREAM_SANDWICH

2011年10月：Android 4.0。

面向此版本或更高版本的应用程序将获得这些行为的新变化：

• 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: Theme_DeviceDefault. This may be the holo dark theme or a different dark theme defined by the specific device. The 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 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 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.

常量值：14（0x0000000e）

ICE_CREAM_SANDWICH_MR1

int ICE_CREAM_SANDWICH_MR1

2011年12月：Android 4.0.3。

常量值：15（0x0000000f）

JELLY_BEAN

int JELLY_BEAN

2012年6月：Android 4.1。

面向此版本或更高版本的应用程序将获得这些行为的新变化：

• You must explicitly request the READ_CALL_LOG and/or WRITE_CALL_LOG permissions; access to the call log is no longer implicitly provided through READ_CONTACTS and 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 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.

常量值：16（0x00000010）

2012年11月：Android 4.2，莫阿胶豆！

• 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 LAYOUT_DIRECTION_LTR based on the locale etc.
• WebView.addJavascriptInterface requires explicit annotations on methods for them to be accessible from Javascript.

常量值：17（0x00000011）

int KITKAT

2013年10月：Android 4.4，KitKat，另一款美味佳肴。

面向此版本或更高版本的应用程序将获得这些行为的新变化：

• 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 READ_EXTERNAL_STORAGE permission is now always enforced.
• Access to package-specific external storage directories belonging to the calling app no longer requires the READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE permissions.

面向此版本或更高版本的应用程序将获得这些行为的新变化：

• Context.bindService now requires an explicit Intent, and will throw an exception if given an implicit Intent.
• 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 BIND_DREAM_SERVICE permission to be usable.

常量值：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.
