这个错误是由于你的AndroidManifest.xml文件中的一些测试活动（InstrumentationActivityInvoker）缺少了`android:exported`属性的显式定义，而在目标为Android 12及更高版本的应用程序中，当组件具有定义的意图过滤器时，需要为`android:exported`属性指定显式值。你可以按照以下步骤进行修复：

1. 打开`app/src/androidTest/AndroidManifest.xml`文件。

2. 找到以下三个元素：

<activity
    android:name="androidx.test.core.app.InstrumentationActivityInvoker$BootstrapActivity" />

<activity
    android:name="androidx.test.core.app.InstrumentationActivityInvoker$EmptyActivity" />

<activity
    android:name="androidx.test.core.app.InstrumentationActivityInvoker$EmptyFloatingActivity" />

3. 对于每个元素，添加`android:exported`属性并设置一个显式值（`true`或`false`），如下所示：

<activity
    android:name="androidx.test.core.app.InstrumentationActivityInvoker$BootstrapActivity"
    android:exported="false" />

<activity
    android:name="androidx.test.core.app.InstrumentationActivityInvoker$EmptyActivity"
    android:exported="false" />

<activity
    android:name="androidx.test.core.app.InstrumentationActivityInvoker$EmptyFloatingActivity"
    android:exported="false" />

4. 保存文件并重新运行测试。

这样就可以解决`android:exported`未显式定义的错误。希望对你有帮助！如果还有其他问题，请随时提问。
