为什么下载好的pedometer在我的android虚拟机上无法运行呢

Question

想实践一下pedometer的效果，所以在网上找了下，有源码，下载地址为http://code.google.com/p/pedometer/但是在本机上导入项目后，启动虚拟机时提示出现异常，只能强制关闭..........我导入的时候设定android包是2.3.3，AndroidManifest.xml文件代码为<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="name.bagi.levente.pedometer"
      android:versionName="1.1.0" android:versionCode="2">
      
    <uses-sdk android:minSdkVersion="3" />    <uses-permission android:name="android.permission.WAKE_LOCK" />    <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="false">
        <activity android:name=".Pedometer"
                  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=".Settings"
                android:label="@string/activity_settings">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>        <service android:name=".StepService"/>    </application>
</manifest> 请问问题是出在那里了呢？求教！！！感激不尽
