Flutter和Android发布aab包时，'android:exported=true'无效。

Question

我试图上传AAB文件到Play控制台，但是提示上传了一个具有意图过滤器的活动、活动别名、服务或广播接收器的APK或Android应用捆绑包，但没有设置'android:exported'属性。该文件无法在Android 12或更高版本上安装。请参见：developer.android.com/about/versions/12/behavior-changes-12#exported错误。我还将exported=true属性设置为该活动。同时添加了android:exported="true" tools:node="merge"。

根据建议，我已经在清单中进行了更改，但仍然遇到同样的问题。

你的compileSdkVersion和targetSdkVersion是多少？应该是30或31。 - Hardik Mehta

它的compileSdkVersion为31，targetSdkVersion也为31。 - Ankur Shinde

请尝试不使用 tools:node="merge" 工具。 - Hardik Mehta

是的，我也尝试过不加它。但仍然出现相同的错误。如果我从其他库将exported = false更改为true，那么它将开始向构建报告错误。 - Ankur Shinde

你能分享一下那个错误吗？ - Hardik Mehta

Answer 1

我会全局搜索所有导出的值集清单文件。在这些文件之间，我只会更改 Firebase Messaging 的清单文件中的值。我将在 Firebase Messaging 的清单文件中设置 android:exported="true"。

你能分享一下你的代码，看看应该在哪里添加吗？ - MD ZDN

打开 Android 模块中的项目，全局搜索 "android:exported" 并将值更改为 true。 - Ankur Shinde

Answer 2

使用Android Studio打开您的Android清单文件，并查看由其他Flutter包生成的合并选项卡，以了解活动、活动别名、服务或带有意图过滤器的广播接收器。

将android:exported="true"添加到任何具有意图过滤器的活动、活动别名、服务或广播接收器中。
