我在使用“android:name="ManageApps"”的第二个 Activity 上收到此错误，
'net.web44.jimappdev.thecoincollector.ManageApps' is not assignable to 'android.app.Activity' Validates resource references inside Android XML files.

最佳答案
看起来您的 ManageApps Activity 不在包 namespace 中:
<activity
android:name="ManageApps"
android:label="@string/app_name">
<intent-filter>
<action android:name="net.web44.jimappdev.thecoincollector.manageapps" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
名称必须以 . 开头才能被视为包 namespace 的一部分:
android:name=".ManageApps"
此外，尽管我不是 100% 确定，但我始终假设操作名称区分大小写。在上面的 list 部分中，您使用 manageapps 作为操作名称的最后一部分，而在 Java 代码中构建 Intent 时以混合大小写的方式使用它:
startActivity(new Intent("net.web44.jimappdev.thecoincollector.ManageApps"));
