我试图解决这个问题很长时间，但仍然被卡住。我已经在 AndroidManifest.xml 文件中声明了我的 Activity，但仍然发生 ActivityNotFoundException，请帮助！

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sel.appsinfo" >

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/MyAppTheme" >
    <activity
        android:name="com.sel.appsinfo.AppsInfoMainActivity"
        android:uiOptions="splitActionBarWhenNarrow" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity></application>

看起来 AppsInfoMainActivity 扩展了 BaseActivity 但 BaseActivity 扩展了其他可能无效的内容。确保它正在扩展 Activity 或 AppCompat Activity 类并且导入正确

确保包含 MAIN 的 XML 中的 Intent Filter 标记也包含

<category android:name="android.intent.category.DEFAULT" />

我认为您的课程路径有问题。请检查类路径，如果错误，请更正。

我解决了，这是因为我有太多不必要的库：|

如果它正在扩展 Activity 或 AppCompat Activity 类并且导入正确，则依赖项列表中可能有 2 个版本的 android-support-v4.jar，但并非所有版本都相同（仅在此检查基于 SHA-1时间）。一切都必须相同。

嗯，也许清洁项目会有所帮助。
