Deep-linking not fired from WebView

问题

I understand your request. Here is the translation of the code you provided:

  1. 我正在尝试从应用程序的 WebView 中触发我的Android应用程序中的深层链接，但是在触发 ACTION_VIEW 意图时，我收到了 `ERR_UNKNORN_URL_SCHEME` 错误，该网站试图执行 `window.location.href = app://ls.mydomain.it/?key=XXX`。
  3. WebView 在 Fragment 中加载如下：
  5.         binding.webview.settings.javaScriptEnabled = true
  6.         binding.webview.settings.loadWithOverviewMode = true
  7.         binding.webview.webViewClient = object : WebViewClient() {
  8.             override fun shouldOverrideUrlLoading(view: WebView?, request: WebResourceRequest?): Boolean {
  9.                 return false
  10.             }
  11.         }
  12.         binding.webview.settings.domStorageEnabled = true
  13.         binding.webview.loadUrl("https://ls.mydomain.it/?deviceId=${deviceId}")
  15. 我已经在清单中添加了深层链接：
  17.         <activity
  18.             android:name=".ui.components.home.HomeActivity"
  19.             android:exported="true"
  20.             android:screenOrientation="portrait"
  21.             android:theme="@style/Theme.App.Starting"
  22.             android:windowSoftInputMode="adjustPan"
  23.             android:launchMode="singleTask"
  24.             tools:ignore="LockedOrientationActivity">
  25.             <intent-filter>
  26.                 <action android:name="android.intent.action.MAIN" />
  27.                 <category android:name="android.intent.category.LAUNCHER" />
  28.             </intent-filter>
  29.             <intent-filter>
  30.                 <action android:name="android.intent.action.VIEW" />
  31.                 <category android:name="android.intent.category.DEFAULT" />
  32.                 <category android:name="android.intent.category.BROWSABLE" />
  34.                 <data android:scheme="app" android:host="ls.mydomain.it" />
  35.             </intent-filter>
  36.         </activity>
  38. 然后在 Activity 中覆盖了意图：
  40.     override fun onNewIntent(intent: Intent?) {
  41.         super.onNewIntent(intent)
  43.         if (intent?.action == Intent.ACTION_VIEW) {
  44.             val data: Uri? = intent.data
  45.             newLicense(data)
  46.         }
  47.     }

Is there anything else you would like to know or clarify?

英文:

I'm trying to fire the deep-linking in my Android application from the application WebView but instead of firing the ACTION_VIEW intent i get ERR_UNKNORN_URL_SCHEME, the website tries to make a window.location.href = app://ls.mydomain.it/?key=XXX.

The WebView is load in a Fragment like this:

  1.     binding.webview.settings.javaScriptEnabled = true
  2.     binding.webview.settings.loadWithOverviewMode = true
  3.     binding.webview.webViewClient = object : WebViewClient() {
  4.         override fun shouldOverrideUrlLoading(view: WebView?,request: WebResourceRequest?): Boolean {
  5.             return false
  6.         }
  7.     }
  8.     binding.webview.settings.domStorageEnabled = true
  9.     binding.webview.loadUrl(&quot;https://ls.mydomain.it/?deviceId=${deviceId}&quot;)

I have added the deep-linking in the Manifest:

  1.     &lt;activity
  2.         android:name=&quot;.ui.components.home.HomeActivity&quot;
  3.         android:exported=&quot;true&quot;
  4.         android:screenOrientation=&quot;portrait&quot;
  5.         android:theme=&quot;@style/Theme.App.Starting&quot;
  6.         android:windowSoftInputMode=&quot;adjustPan&quot;
  7.         android:launchMode=&quot;singleTask&quot;
  8.         tools:ignore=&quot;LockedOrientationActivity&quot;&gt;
  9.         &lt;intent-filter&gt;
  10.             &lt;action android:name=&quot;android.intent.action.MAIN&quot; /&gt;
  11.             &lt;category android:name=&quot;android.intent.category.LAUNCHER&quot; /&gt;
  12.         &lt;/intent-filter&gt;
  13.         &lt;intent-filter&gt;
  14.             &lt;action android:name=&quot;android.intent.action.VIEW&quot; /&gt;
  15.             &lt;category android:name=&quot;android.intent.category.DEFAULT&quot; /&gt;
  16.             &lt;category android:name=&quot;android.intent.category.BROWSABLE&quot; /&gt;
  18.             &lt;data android:scheme=&quot;app&quot; android:host=&quot;ls.mydomain.it&quot; /&gt;
  19.         &lt;/intent-filter&gt;
  20.     &lt;/activity&gt;

And then override the intent in the Activity:

  1. override fun onNewIntent(intent: Intent?) {
  2.     super.onNewIntent(intent)
  4.     if (intent?.action == Intent.ACTION_VIEW) {
  5.         val data: Uri? = intent.data
  6.         newLicense(data)
  7.     }
  8. }

I've solved the issue by calling the startActivity with ACTION_VIEW intent which contains the deep-link URI by overriding the shouldOverrideUrlLoading。

The WebViewClient looks like this now:

  1. binding.webview.webViewClient = object : WebViewClient() {
  2.     override fun shouldOverrideUrlLoading(view: WebView?, request: WebResourceRequest?): Boolean {
  3.         val url = request?.url.toString()
  4.         if (url.startsWith("app://")) {
  5.             try {
  6.                 val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url)).apply {
  7.                     addCategory(Intent.CATEGORY_BROWSABLE)
  8.                     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
  9.                         flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_REQUIRE_NON_BROWSER or
  10.                                 Intent.FLAG_ACTIVITY_REQUIRE_DEFAULT
  11.                     }
  12.                 }
  13.                 startActivity(intent)
  14.             } catch (e: ActivityNotFoundException) {
  15.                 showToast("Non è stato possibile attivare la licenza, contattare l'assistenza")
  16.             }
  17.             return true
  18.         }
  20.         return false
  21.     }
  22. }

With FLAG_ACTIVITY_REQUIRE_NON_BROWSER and FLAG_ACTIVITY_REQUIRE_DEFAULT flags, the intent will match only the URI that matches the application deep-linking.

  16.                 }
  17.                 return true
  18.             }
  20.             return false
  21.         }
  22.     }

With FLAG_ACTIVITY_REQUIRE_NON_BROWSER and FLAG_ACTIVITY_REQUIRE_DEFAULT flags the intent will match only the URI that matches the application deep-linking.
