  • The default theme for applications is now dark holographic: * {@link 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 * {@link android.app.Activity}. *
  • An application will crash if it does not call through * to the super implementation of its * {@link android.app.Activity#onPause 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.

*

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 * {@link #HONEYCOMB} or later; it had been {@link #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 * {@link android.content.res.Configuration#screenWidthDp}, * {@link android.content.res.Configuration#screenHeightDp}, and * {@link android.content.res.Configuration#smallestScreenWidthDp}. * Supplying these in <supports-screens> as per * {@link android.content.pm.ApplicationInfo#requiresSmallestWidthDp}, * {@link android.content.pm.ApplicationInfo#compatibleWidthLimitDp}, and * {@link 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 {@link android.content.pm.PackageManager#FEATURE_SCREEN_PORTRAIT} * and {@link 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.

    *
  • {@link android.os.AsyncTask} will use the serial executor * by default when calling {@link android.os.AsyncTask#execute}.

    *
  • {@link android.content.pm.ActivityInfo#configChanges * ActivityInfo.configChanges} will have the * {@link android.content.pm.ActivityInfo#CONFIG_SCREEN_SIZE} and * {@link 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. *

*/ public static final int HONEYCOMB_MR2 = 13; /** * October 2011: Android 4.0. *

*

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

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

*
    *
  • You must explicitly request the {@link android.Manifest.permission#READ_CALL_LOG} * and/or {@link android.Manifest.permission#WRITE_CALL_LOG} permissions; * access to the call log is no longer implicitly provided through * {@link android.Manifest.permission#READ_CONTACTS} and * {@link android.Manifest.permission#WRITE_CONTACTS}. *
  • {@link android.widget.RemoteViews} will throw an exception if * setting an onClick handler for views being generated by a * {@link android.widget.RemoteViewsService} for a collection container; * previously this just resulted in a warning log message. *
  • New {@link 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. *
  • {@link android.webkit.WebSettings#setAllowFileAccessFromFileURLs(boolean) * WebSettings.setAllowFileAccessFromFileURLs} and * {@link android.webkit.WebSettings#setAllowUniversalAccessFromFileURLs(boolean) * WebSettings.setAllowUniversalAccessFromFileURLs} default to false. *
  • Calls to {@link android.content.pm.PackageManager#setComponentEnabledSetting * PackageManager.setComponentEnabledSetting} will now throw an * IllegalArgumentException if the given component class name does not * exist in the application's manifest. *
  • {@link android.nfc.NfcAdapter#setNdefPushMessage * NfcAdapter.setNdefPushMessage}, * {@link android.nfc.NfcAdapter#setNdefPushMessageCallback * NfcAdapter.setNdefPushMessageCallback} and * {@link android.nfc.NfcAdapter#setOnNdefPushCompleteCallback * NfcAdapter.setOnNdefPushCompleteCallback} will throw * IllegalStateException if called after the Activity has been destroyed. *
  • Accessibility services must require the new * {@link android.Manifest.permission#BIND_ACCESSIBILITY_SERVICE} permission or * they will not be available for use. *
  • {@link android.accessibilityservice.AccessibilityServiceInfo#FLAG_INCLUDE_NOT_IMPORTANT_VIEWS * AccessibilityServiceInfo.FLAG_INCLUDE_NOT_IMPORTANT_VIEWS} must be set * for unimportant views to be included in queries. *
