仔细阅读红色字体处的报错信息知道：原来是我编写的APP中含有的多个Activity，必须要在AndroidManifest.xml中进行声明，声明如下：

<?xml version="1.0" encoding="utf-8"?>

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

    package="com.himi.clock"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk

        android:minSdkVersion="15"

        android:targetSdkVersion="17" />

    <application

        android:allowBackup="true"

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme" >

        <activity

            android:name=".MainActivity"

            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=".ClockActivity" />

        <activity android:name=".StopwatchActivity" />

        <activity android:name=".TimerActivity" />

    </application>

</manifest>

再次加载程序到手机里面，发现这时候是可以运行的，没有报错了

那么为什么要这样在AndroidManifest.xml声明注册多个activity？？？

答：我们知道不同activity代表不同的窗口界面，Android系统只有先注册了不同的activity，系统内部才能对它操作，比如利用intent操作。
