Framework API
以下部分介绍了对 Android 2.0.1 平台提供的应用框架 API 所做的更改。不过，请注意，Android 2.0.1 是 Android 2.0 的次要版本，因此如需详细了解对 Android 2.0 所做的更改，请参阅 Android 2.0 版本说明。
API 级别
Android 2.0.1 平台提供了更新后的框架 API 版本。Android 2.0.1 API 会被分配一个整数标识符（6），该标识符存储在系统本身中。此标识符称为“API 级别”，可让系统在安装应用之前正确确定应用是否与系统兼容。
如需在应用中使用 Android 2.0.1 中引入的 API，您需要在应用清单的 <uses-sdk> 元素的属性中设置适当的值“6”。
如需详细了解如何使用 API 级别，请参阅 API 级别文档。
API 变更摘要
下面总结了框架 API 的变更。
行为变更
下面总结了会影响某些框架 API 行为但不会添加或移除 API 功能的变更。
蓝牙
ACTION_REQUEST_ENABLE 和 ACTION_REQUEST_DISCOVERABLE 返回的值发生了变化：
现在，如果联系人未持久化（例如，保存操作被修剪为无操作），ACTION_INSERT intent 会返回 RESULT_CANCELED。
问题修复
以下简要介绍了影响某些框架 API 的 bug 修复。
资源
该框架现在会正确选择使用 API 级别限定符的项目文件夹中的应用资源。例如，drawable-v4/ 是适用于 API 级别 4（或更高级别）设备的可绘制资源文件夹。此版本匹配功能无法正常运行，现已修复。
现在，当使用（现已废弃的）Contacts API 发出请求时，ACTION_INSERT intent 会返回适当类型的 URI。
其他框架修复
API 差异报告
如需详细了解 Android 2.0.1（API 级别 6）与 API 级别 5 中的 API 变更，请参阅 API 差异报告。API 级别 6 中的 API 变更非常少，因此您可能还会对 4 和 5 之间的 API 差异感兴趣。

Release-mode signing includes integrated support for `zipalign` optimization. For more information, see [Signing Your Applications](/tools/publishing/app-signing#releasecompile).\n- Adds new Ant build system with support for Emma instrumentation projects (code coverage).\n\nFramework API\n-------------\n\nThe sections below provide information about changes made to the application\nframework API provided by the Android 2.0.1 platform. Note,\nhowever, that Android 2.0.1 is a minor release to Android 2.0, so for more\ninformation about the changes made to in Android 2.0, please refer to the\n[Android 2.0 version notes](/about/versions/android-2.0#api).\n\n### API level\n\nThe Android 2.0.1 platform delivers an updated version of the framework\nAPI. The Android 2.0.1 API\nis assigned an integer identifier --- **6** --- that is\nstored in the system itself. This identifier, called the \"API Level\", allows the\nsystem to correctly determine whether an application is compatible with\nthe system, prior to installing the application.\n\nTo use APIs introduced in Android 2.0.1 in your application, you need to\nset the proper value, \"6\", in the attributes of the `\u003cuses-sdk\u003e`\nelement in your application's manifest.\n\nFor more information about how to use API Level, see the [API Levels](/guide/topics/manifest/uses-sdk-element#ApiLevels) document.\n\n### API changes summary\n\nThe following is a summary of changes to the framework APIs.\n\n- New `quickContactBadgeStyle*` attributes that let applications apply necessary styles to the [QuickContactBadge](/reference/android/widget/QuickContactBadge) widget.\n- Remove support for the [ACTION_CONFIGURATION_CHANGED](/reference/android/content/Intent#ACTION_CONFIGURATION_CHANGED) broadcast when declared as a filter in the manifest. To receive this broadcast, an application must do so from the application at run-time, with [registerReceiver(BroadcastReceiver, IntentFilter)](/reference/android/content/Context#registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter)).\n\n### Behavior changes\n\nThe following is a summary of changes that affect the behavior of some\nframework APIs but do not add or remove API functionality.\n\n#### Bluetooth\n\nChanges to the values returned by [ACTION_REQUEST_ENABLE](/reference/android/bluetooth/BluetoothAdapter#ACTION_REQUEST_ENABLE) and\n[ACTION_REQUEST_DISCOVERABLE](/reference/android/bluetooth/BluetoothAdapter#ACTION_REQUEST_DISCOVERABLE):\n\n- [ACTION_REQUEST_ENABLE](/reference/android/bluetooth/BluetoothAdapter#ACTION_REQUEST_ENABLE) now returns [RESULT_OK](/reference/android/app/Activity#RESULT_OK) if Bluetooth was successfully enabled and [RESULT_CANCELED](/reference/android/app/Activity#RESULT_CANCELED) if the user rejected the request to enable Bluetooth, rather than 0 and -1 (or -2), respectively.\n- [ACTION_REQUEST_DISCOVERABLE](/reference/android/bluetooth/BluetoothAdapter#ACTION_REQUEST_DISCOVERABLE) now returns [RESULT_CANCELED](/reference/android/app/Activity#RESULT_CANCELED) if the user rejected the request to enable discoverability or if Bluetooth is not enabled, rather than -1 and -2, respectively.\n\n#### Contacts\n\nThe [ACTION_INSERT](/reference/android/content/Intent#ACTION_INSERT) Intent now returns [RESULT_CANCELED](/reference/android/app/Activity#RESULT_CANCELED) in cases where the contact was not\npersisted (for example, if the save was trimmed to a no-op).\n\n### Bug fixes\n\nThe following is a summary of bug fixes that affect some framework APIs.\n\n#### Resources\n\nThe framework now correctly selects application resources in project\nfolders that use the API Level qualifier. For example, `drawable-v4/` is a\nfolder of drawable resources for API Level 4 (or higher) devices. This version\nmatching did not work properly and has been fixed.\n\n#### Contacts\n\nThe [ACTION_INSERT](/reference/android/content/Intent#ACTION_INSERT) Intent now returns the\nappropriate kind of URI when the request is made using the (now\ndeprecated) [Contacts](/reference/android/provider/Contacts) APIs.\n\n#### Other Framework fixes\n\n- [getCallingPackage()](/reference/android/app/Activity#getCallingPackage()) now properly reports the package name, rather than the process name.\n\n### API differences report\n\nFor a detailed view of API changes in Android 2.0.1 (API Level 6), as compared to\nAPI Level 5, see the [API\nDifferences Report](/sdk/api_diff/6/changes). There are very few API changes in API Level 6,\nso you might also be interested in reviewing the [API\ndifferences between 4 and 5](/sdk/api_diff/5/changes)."]]
