我正在尝试为 Android 编写语音文本应用程序。现在该应用程序不会在模拟器上崩溃，但是当我将其上传到三星 Galaxy s 1900 时，我在 Eclipse 中收到以下错误消息:

在模拟器中运行时，程序只是说模拟器不支持语音，但不会崩溃。

我已经检查过最小 API 不是太高，但 Eclipse 已将其设置为 2.2，所以我认为这很好。
有人知道可能出了什么问题或如何调试吗？
亲切的问候，
最佳答案
问题是您正在尝试使用 ActionBar在运行 Android 2.2(API 级别 8)的设备上，但 ActionBar 是在 API 级别 11 中添加的。
所以你基本上有两个选择:
- 不要在您的应用中使用
ActionBar。 - 使用
ActionBarSherlock库，它将操作栏向后移植回 Android 2.x(尽管您仍然需要在代码中进行一些细微的更改，请阅读ActionBarSherlock的文档以了解更多详细信息)。
