我有一个片段，我正试图从一个按钮单击开始另一个活动，如下所示：

Intent i = new Intent(getActivity(), RoundPagerActivity.class);
// put extras
startActivity(i);

应用程序在调用 时startActivity(i)崩溃Fatal Exception。这是日志猫：

这是我的清单文件：

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

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

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

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

        <!-- other activities -->

        <!-- activity that calls the pager activity -->
        <activity
            android:name="com.wilk.android.tablink.RoundListActivity"
            android:label="@string/app_name" >

        </activity>

        <!-- activity that is called -->
        <activity
            android:name="com.wilk.android.tablink.RoundPagerAcivity"
            android:label="@string/app_name" >
            <meta-data
                android:name="android.support.PARENT_ACTIVITY"
                android:value="com.wilk.android.tablink.RoundListActivity" />

        </activity>

    </application>

</manifest>

奇怪的是，我有另一个应用程序以完全相同的方式执行此操作而没有问题。我在这里查看了其他问题，并且很确定我已经用尽了这些选择，至少是那些似乎适用的选择。我也尝试在新活动中设置断点，但没有一个被击中。谁能看到我刚刚忽略的东西？

它在您的清单中拼写错误。你有：android:name="com.wilk.android.tablink.RoundPagerAcivity"它应该是android:name="com.wilk.android.tablink.RoundPagerActivity"。

另外，我不知道这是否重要，但在我的应用程序中，我还有一个关于“详细信息”活动的属性，如下所示：

    <activity
        android:name="com.wilk.android.tablink.RoundPagerActivity"
        android:label="@string/app_name"
        android:parentActivityName="com.wilk.android.tablink.RoundListActivity">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.wilk.android.tablink.RoundListActivity" />
    </activity>
