Question

我有一个Android / Kotlin应用程序，我想配置某些页面的深层链接，以便在我的应用程序中打开（看起来像本机）。

目前，我有意图过滤器，用户将用户重定向到使用WebView的活动，我在其中打开所需的网址：

<activity android:name=".activity.WebViewActivity">
        <intent-filter android:label="Futurity">
            <action android:name="android.intent.action.VIEW" />

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data
                android:host="api.example.com"
                android:pathPrefix="/auth/confirm"
                android:scheme="https" />
        </intent-filter>
</activity>

class WebViewActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_web_view)

        val data = intent.data

        // construct url
        val url = if (intent.data != null ) {
            "https://" + data.host + data.path + "?" + data.query
        }

        appWebView.webViewClient = WebViewClient()
        appWebView.loadUrl(url)
    }
}

这很好用，但出于安全考虑，我想使用Chrome自定义标签。

但是，当我尝试配置自定义选项卡而不是WebView时，我在页面（在chrome选项卡中启动）和intent过滤器之间获得了无限循环重定向，后者立即将用户重定向回活动：

CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder();
CustomTabsIntent customTabsIntent = builder.build();
customTabsIntent.launchUrl(this, Uri.parse(url));

如何实现与webviews相同的行为但不修改网址？它甚至可行吗？

我做了一些挖掘，发现你应该搜索支持＆＃34;温暖服务的套餐＆＃34;。如果返回包，则可以将包名称分配给Intent。 Google有一些带有帮助类的GitHub仓库。有问题的是CustomTabHelper#getPackageNameToUse()。

所以在你的情况下：

如果找不到包裹，那么您会想要一些后备代码，否则无限循环会继续发生。
