为什么 CustomTabsClient.bindCustomTabsService 不起作用？

Question

我最近一直致力于向我的 Android 应用程序添加一些Chrome 自定义选项卡，但由于某种原因，我无法绑定到 CustomTabsService。

• 我有 Chrome 的更新版本
• Android Gradle 插件版本 4.0.0
• 摇篮版本 6.1.1

我添加了日志调用来查看连接是否成功，但从未成功。我尝试使用 CustomTabsCallback 根据用户在 CustomTabs 中的导航采取操作，但我需要先连接到该服务。任何帮助表示赞赏！

依赖关系

// Custom Tabs
    implementation 'androidx.browser:browser:1.3.0-alpha01'
    implementation 'com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava'

我也尝试过这个（当前版本在这里）：

implementation 'androidx.browser:browser:1.2.0'

Answer 1

Android 11 引入了包可见性更改。如果您的 Android 应用程序的目标 API 级别为 30 或更高级别，则需要向 AndroidManifest.xml 添加查询部分，否则上面的代码片段将不会返回结果：

<queries>
    <intent>
        <action android:name=
            "android.support.customtabs.action.CustomTabsService" />
    </intent>
</queries>

Answer 2

事实证明这是一个愚蠢的错误。CustomTabsClient.bindCustomTabsService 方法需要自定义选项卡服务的包名称，而不是调用活动的包。所以这...

var ok =  CustomTabsClient.bindCustomTabsService(main, main.packageName, serviceConnection)

应该...

var ok =  CustomTabsClient.bindCustomTabsService(main, "com.android.chrome", serviceConnection)

可以在此处找到可能的包名称。他们包括：

• com.android.chrome
• com.chrome.beta
• com.chrome.dev
