我是 Android 中 Map View 实现的新手。我正在尝试启动一个包含谷歌地图的新活动（单击按钮）。我似乎正在做http://developer.android.com/guide/tutorials/views/hello-mapview.html中提到的所有事情。但是我收到以下错误：-

这是 showLocator 方法的样子：-

public void showLocator(View view) {
    Intent i = new Intent(SelfDefActivity.this, LocationActivity.class);
    final int result=1;
    startActivityForResult(i, result);
    finish();
}

这就是我的清单的样子：--

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="org.sam"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="10" />

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.NoTitleBar" >
        <activity
            android:name=".SelfDefActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".LocationActivity"
            android:label="@string/location_activity" >
            <uses-library android:name="com.google.android.maps" />
        </activity>
    </application>

</manifest>

谁能告诉我哪里出错了？

在清单文件中为您的活动添加完整路径

像android:name="your package name.LocationActivity"

正如您的活动名称所暗示的那样，您正在检查位置，您应该为此添加权限，如下所示

您的清单应如下所示

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="org.sam"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="10" />

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.NoTitleBar" >
        <activity
            android:name=".SelfDefActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".LocationActivity"
            android:label="@string/location_activity" >   
        </activity>
        <uses-library android:name="com.google.android.maps" />
    </application>

</manifest>

你试试这种类型

</application>
         <activity
          ......
          .....

         </activity>

 <uses-library android:name="com.google.android.maps" />

</application>
