Apps targeting Android 12 and higher are required to specify

如果应用以 Android 12 或更高版本为目标平台,并且包含使用 intent 过滤器的 activity、服务或广播接收器,那么必须为这些应用组件显式声明 `android:exported` 属性。如果未显式声明 `android:exported` 的值,您的应用将无法在搭载 Android 12 或更高版本的设备上进行安装。

Apps targeting Android 12 and higher are required to specify an explicit value for `android
:exported` attribute in the AndroidManifest.xml file for all components (activities, services, receivers, providers). This attribute indicates whether a component is accessible from other apps or not. It helps enhance the security of Android apps by explicitly defining the accessibility of each component.
Previously, if this attribute was not specified, the default behavior was that components were considered exported. However, starting from Android 12, specifying an explicit value for this attribute is mandatory for all components.
To specify the value for `android:exported`, you need to set it to either `true` or `false` depending on your app's requirements. If you want to allow other apps to access the component, set it to `true`. If you want to restrict access to only your app, set it to `false`.
Here is an example of how the `android:exported` attribute can be set for an activity in the AndroidManifest.xml file:
```xml
<activity android:name=".MainActivity"
...
android:exported="true">
...
</activity>
```
Make sure to review and update the `android:exported` attribute for all components in your AndroidManifest.xml file when targeting Android 12 and higher to comply with the new requirement.

如果您的应用程序的目标版本是Android 12或更高版本,则需要指定`android:exported`属性的显式值。这是因为在Android 12中,`android:exported`属性默认值将更改为false,以提高应用程序安全性。
要解决此错误提示,请在应用程序的AndroidManifest.xml文件中明确指定`android:exported`属性的值。例如,如果您希望允许其他应用程序调用您的活动,则可以将`android:exported`属性设置为true。如果您不希望活动可以由其他应用程序调用,则应将`android:exported`属性设置为false。例如:
```
<activity
android:name=".MainActivity"
android:exported="true">
...
</activity>
```
请注意,这只是一个示例,您需要根据您的应用程序的实际情况进行修改。
