如要瞭解裝置的預設瀏覽器或任何瀏覽器是否支援自訂分頁,請在 CustomTabsClient
中使用 getPackageName
輔助工具:
String packageName = CustomTabsClient.getPackageName(
context,
Collections.emptyList()
);
if (packageName == null) {
// Custom Tabs are not supported by the default browser
}
你也可以查看裝置上的任何瀏覽器是否支援「自訂分頁」:
// Get all apps that can handle VIEW intents and Custom Tab service connections.
Intent activityIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.example.com"));
PackageManager packageManager = context.getPackageManager();
List<ResolveInfo> viewIntentHandlers = packageManager.queryIntentActivities(activityIntent, 0);
// Get a package that supports Custom Tabs
String packageName = CustomTabsClient.getPackageName(
context,
viewIntentHandlers,
true /* ignore default */
);
if (packageName == null) {
// Custom Tabs are not supported by any browser on the device
}
Android 11 推出了套件瀏覽權限變更。如果您的 Android 應用程式指定的 API 級別為 30 以上,則必須在 AndroidManifest.xml
中新增下列查詢部分,否則上述程式碼片段不會傳回結果:
<queries>
<intent>
<action android:name=
"android.support.customtabs.action.CustomTabsService" />
</intent>
</queries>
