请看以下几行： android.content.ActivityNotFoundException:找不到显式活动类{com.thenewboston.travis/com.thenewboston.travis.Data}；您是否在AndroidManifest.xml中声明了此活动？03-12 18:30:01.853:E/AndroidRuntime（331）

这是您的答案，您没有在AndroidManifest.xml中声明您的活动，请在清单文件中添加以下代码：

您必须向我们提供堆栈跟踪。答案就在这个堆栈跟踪中。对于引用同一个idcool，您有start和start。我听说过它03-11 19:41:59.913:E/AndroidRuntime（317）：at java.lang.reflect.Method.invokenactive（本机方法）03-11 19:41:59.913:E/AndroidRuntime（317）：at java.lang.reflect.Method.invoke（Method.java:521）03-11 19:41:59.913:E/AndroidRuntime（317）：在com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run（ZygoteInit.java:868）03-11 19:41:59.913:E/AndroidRuntime（317）：在com.android.internal.os.ZygoteInit.main（ZygoteInit.java:626）03-11 19:41:59.913:E/AndroidRuntime（317）：在dalvik.system.NativeStart.main（本机方法）这不是一个完整的错误跟踪，请将其发布在您的问题中，而不是评论中。但它设置在意图括号中，例如…boston.travis.Data>和intent.category.default抱歉，非常抱歉，您的权利要求我在.activity菜单中的活动有多愚蠢
