显然,在代码中有一个关于android:exported的错误,这应该是真的。在这个错误中,我必须明确声明android:exported=“true”是关于接收器的。现在我的问题是,我在AndroidManifest中根本没有使用接收器。请根据我所附的AndroidManifest的图片和源代码提供帮助。

exported出现问题。您需要将android:exported="false"设置为所有其他活动(android:exported="true"用于启动活动或启动活动)。
如果您的目标是android〉=12,则将所有其他活动设置为android:exported="false"
如以下代码

<activity
            android:name="com.Coading.freecode.activity.MainActivity"
            android:screenOrientation="portrait"
            android:exported="false" // as here mentioned
            android:windowSoftInputMode="adjustPan" />

导出的属性用于定义应用中的Activity、服务或接收器是否可访问以及是否可从外部应用启动。
强制定义每个Activity、服务和接收器的导出值增加了一层新的安全性,因为开发人员需要设置它才能将应用编译到Android 12。
请参见文档https://developer.android.com/about/versions/12/behavior-changes-12#exported
