url_launcherをAndroidで動作しない問題(flutter)

Posted at

起きていた問題

以下をAndroidで試そうとしても"Could not launch url"となってしまう。

import 'package:url_launcher/url_launcher.dart';

 onTap: () {
  launchURL("https://www.google.com");
},
..............
  launchURL(String url) async {
    if (await canLaunch(url)) {
      await launch(url);
    } else {
      throw 'Could not launch $url';
    }
  }

解決策

以下をandroid>app>src>AndroidManifest.xmlに追記。

<!-- Nest within the manifest element, not the application element-->
<queries>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="https" />
    </intent>
    <intent>
        <action android:name="android.intent.action.DIAL" />
        <data android:scheme="tel" />
    </intent>
    <intent>
        <action android:name="android.intent.action.SEND" />
        <data android:mimeType="*/*" />
    </intent>
</queries>

<application>
    ....
</application>
