为什么注册了activity还报错呢？
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.whxph.activity02.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>

这里是我的注册：
<activity
android:name=".OtherAvtivity"
android:label="@string/other">
</activity>
</application>

报错：
android.content.ActivityNotFoundException: Unable to find explicit activity class {com.whxph.activity02/com.whxph.activity02.OtherActivity}; have you declared this activity in your AndroidManifest.xml? Android activity
[解决办法]
OtherAvtivity 你是不是把c写成v了？
[解决办法]
貌似Activity的Ac写成Av了...
