您可以使用Store_redirect包。

StoreRedirect.redirect(androidAppId: "com.iyaffle.rangoli",
                    iOSAppId: "585027354");

您可以更改DNS服务器并选择手动选项。转到Apple菜单，然后转到系统偏好设置〉网络。一些谷歌公共DNS服务器示例：：8.8.8.88.8.4.4我用这种方法解决了同样的问题。

在应用程序上方的AndroidManifest.xml中添加以下依赖项

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES" />

<queries>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="https" />
    </intent>
    <!-- If your app opens https URLs -->
    <intent>
        <action android:name="android.intent.action.VIEW" />
