Answer 1

没有在AndroidManifest.xml里面声明com.example.aboutme.welcome这个activity吧。

追问

是这样吗

追答

嗯。用.welcom做android:name的话，先确定你的packagename是不是对的。

追问

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.aboutme"

我第一次的APP没有声明welcome这个activity，然后发送给真机了，是不是eclipse中没有更新我后来修改的APP呢

追答

项目有变动之后，要在eclipse中重新run才能更新。

追问

唉，我重新生成了一个APK都没用，我还是慢慢找错吧

Answer 2
