我正在用android开发我的项目。其基于位置的服务。在这里，我尝试在单个项目下结合三个活动。所以我在布局中创建了三个 xml 文件。并且还包括 Manifest 中的三个活动。但是当我尝试执行我的项目时，它显示应用程序已意外停止。请再试一次。我认为这个错误在 R.java 中。但我不知道确切的错误。请帮助我。

我的 logcat 显示像

你在使用文字转语音吗？从 logcat 看起来你是。要使用 TTS，您必须首先检查设备上是否安装了 TTS。

这个答案显示了如何检查它是否已安装：

SpeechToText 并运行 ACTION_CHECK_TTS_DATA 意图

这可能与这里的问题相同

无法实例化服务：ClassNotFoundException

由于最近的 ADT 更新，只需要将“lib”文件夹更改为“libs”...
