为什么CustomTabsClient.bindCustomTabsService不能工作？

Question

我最近一直在努力增加一些 浏览器自定义标签 到我的 Android 应用程序中，但由于某些原因，我无法绑定到 CustomTabsService。

• 我有一个更新版本的 Chrome
• 安卓Gradle插件4.0.0版
• Gradle版本6.1.1

我已经添加了日志调用，看看我的连接是否成功，但它从来没有。我试图通过使用CustomTabsCallback来根据用户在CustomTabs中的导航采取行动，但我需要先连接到服务。感谢任何帮助

依赖性

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

我也试过用这个（当前版本是 此处):

implementation 'androidx.browser:browser:1.2.0'

这原来是一个愚蠢的错误。CustomTabsClient.bindCustomTabsService方法需要的是Custom Tabs服务的包名，而不是调用活动的包名。所以这个...

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

应该是...

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

可能的包名可以在下面找到 此处. 它们包括:

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