| 443 | * or later, your UI must always have its own menu UI affordance if needed, |
| 444 | * on both tablets and phones. The ActionBar will take care of this for you. |
Dianne Hackborn | 2d6833b | 2011-06-24 16:04:19 -0700 | [diff] [blame] | 445 | * <li> 2d drawing hardware acceleration is now turned on by default. |

| 447 | * {@link android.R.attr#hardwareAccelerated android:hardwareAccelerated} |
| 448 | * to turn it off if needed, although this is strongly discouraged since |
| 449 | * it will result in poor performance on larger screen devices. |
Adam Powell | 6e90a36 | 2011-08-14 16:48:32 -0700 | [diff] [blame] | 450 | * <li> The default theme for applications is now the "device default" theme: |
| 451 | * {@link android.R.style#Theme_DeviceDefault}. This may be the |
| 452 | * holo dark theme or a different dark theme defined by the specific device. |
| 453 | * The {@link android.R.style#Theme_Holo} family must not be modified |
| 454 | * for a device to be considered compatible. Applications that explicitly |
| 455 | * request a theme from the Holo family will be guaranteed that these themes |
| 456 | * will not change character within the same platform version. Applications |
| 457 | * that wish to blend in with the device should use a theme from the |

Dianne Hackborn | 9d0e37e | 2011-09-22 12:58:54 -0700 | [diff] [blame] | 459 | * <li> Managed cursors can now throw an exception if you directly close |
| 460 | * the cursor yourself without stopping the management of it; previously failures |
| 461 | * would be silently ignored. |
| 462 | * <li> The fadingEdge attribute on views will be ignored (fading edges is no |
| 463 | * longer a standard part of the UI). A new requiresFadingEdge attribute allows |
| 464 | * applications to still force fading edges on for special cases. |
Dianne Hackborn | 81e9276 | 2011-10-09 16:00:21 -0700 | [diff] [blame] | 465 | * <li> {@link android.content.Context#bindService Context.bindService()} |
| 466 | * will not automatically add in {@link android.content.Context#BIND_WAIVE_PRIORITY}. |
| 467 | * <li> App Widgets will have standard padding automatically added around |
| 468 | * them, rather than relying on the padding being baked into the widget itself. |
| 469 | * <li> An exception will be thrown if you try to change the type of a |
| 470 | * window after it has been added to the window manager. Previously this |
| 471 | * would result in random incorrect behavior. |
| 472 | * <li> {@link android.view.animation.AnimationSet} will parse out |
| 473 | * the duration, fillBefore, fillAfter, repeatMode, and startOffset |
| 474 | * XML attributes that are defined. |
