更改活动启动意图错误[重复]

Question

我已将我想首先运行的活动从 MainActivity 更改为另一个。我通过编辑 Android 清单和复制来做到这一点：

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

到我想要的活动。现在，当我在我的 android 设备上运行或调试我的应用程序时，它已成功安装，但它不会像在我必须单击图标之前那样自动启动，我收到下面的错误，如果我在模拟器中运行它，正确的活动只会在第一次安装后它只是忽略该活动并始终启动MainActivity。

请帮忙。

Answer 1

确保只有一个活动中有这个标签

<intent-filter>
        <action android:name="android.intent.action.MAIN" />

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

否则你会混淆系统，android会在菜单中制作两个不同的图标启动器，

是的，从模拟器和设备中卸载所有组件并重新安装应用程序
