Question

我尝试从此GIT中心链接https://github.com/yandex-money/yandex-money-sdk-android启动程序示例。我用Eclipse。但是当它开始运行时，会出现一个错误：其中一个错误 - 无法实例化活动ComponentInfo java.lang.ClassNotFoundException。下面的logcat：

这是我的清单文件的内容：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="ru.yandex.money.android.sample" >

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

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <activity
            android:name="ru.yandex.money.android.sample.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="ru.yandex.money.android.sample.PayActivity"/>

    </application>

</manifest

＆GT; 从主要代码我改变了两件事：我已经将android版本从2.1更改为3.0，在styles.xml文件中我已经将字符串<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar">替换为<style name="AppTheme" parent="android:Theme.Holo">。错误的原因在哪里？
