我的应用程序不断崩溃，我不知道出了什么问题。我只是在应用程序中添加了一个新包

下面的代码是我的 logcat 错误输出

下面是我的android清单文件，我添加了活动意图

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.example.coverflow"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <application 
        android:icon="@drawable/icon" 
        android:label="@string/app_name"
        android:largeHeap="true">
        <activity android:name="com.coverflow.CoverFlowExample"
            android:configChanges="orientation|keyboardHidden"
                  android:label="@string/app_name">

您已经提供了您的包名称package="com.example.coverflow"，并且您正在通过此名称访问您的活动android:name="com.coverflow.CoverFlowExample"。这里你忘记写了example，所以你的全名是错误的。

请改成这样：

android:name="com.example.coverflow.CoverFlowExample"
