--------------------编程问答-------------------- 没有找到这个类：org.example.mymap.MyMap
--------------------编程问答-------------------- 是不是在AndroidManifest.xml 文件中，没有声明 MyMap 这个Activity。 --------------------编程问答-------------------- ++ --------------------编程问答-------------------- 你的类org.example.mymap.MyMap没有在AndroidManifest.xml中进行注册~~~ --------------------编程问答-------------------- Caused by: java.lang.ClassNotFoundException: org.example.mymap.MyMap in loader dalvik.system.PathClassLoader[/data/app/org.example.mymap-1.apk]
主要看这句 --------------------编程问答-------------------- 需要在AndroidManifest.xml中，对Activity进行注册。
--------------------编程问答--------------------
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.example.mymap"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>
<application

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

我注册了啊，大家看看有什么问题吗？ --------------------编程问答--------------------

我注册了啊
--------------------编程问答-------------------- 不会是activity的packagename不对吧？ --------------------编程问答-------------------- 错误找到了 原来是manifest.xml中有一行代码敲错了 <uses-liberary android:name="com.google.android.maps"/> 应该是library 多谢大家
--------------------编程问答-------------------- 楼主，既然解决了，就结贴散分吧。
