尽管设置为 targetSDK 31，但 Flutter 应用程序无法从 Android 12 的 Google 商店安装

Question

我在 Playstore 中有一个 Flutter 应用程序，如果您有 Android 12，它只会弹出一条错误消息：\n“AppName 无法安装”

\n

我的Flutter版本是2.5.0

\n

由于我的设置，我希望该应用程序可以安装在 Android 12 上。是否有任何 \xc3\xb2ther 原因导致此失败？

在 Android 12 模拟器上安装此程序时，安装失败并显示以下消息：

在我将此值添加到我的应用程序清单中后，我再次启动它，并且在 Visual Studio 代码中出现了一个无尽的安装加载图标。我的设备上有该应用程序，但点击它后它会立即关闭

您必须将 android:exported 设置为在 app\xe2\x80\x99s AndroidManifest.xml 文件中声明了 <intent-filter> 的任何 <activity>、<activity-alias>、<service> 或 <receiver> 组件.\nALSO!!!!\n您必须对您使用的每个包执行相同的操作。我建议不要手动执行此操作，因为这可以通过调用“Pubclearcache”之类的内容来修改，而是尝试将包更新到最新版本。
