android - 为什么 CustomTabsClient.bindCustomTabsService 不起作用？

Question

我最近一直在努力添加一些 Chrome Custom Tabs到我的 Android 应用程序，由于某种原因，我无法绑定(bind)到 CustomTabsService。

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

我添加了日志调用来查看我的连接是否成功，但从来没有成功。我正在尝试使用 CustomTabsCallback 根据用户在 CustomTabs 中的导航采取行动，但我需要先连接到服务。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'

我也试过这个(当前版本是 here):

implementation 'androidx.browser:browser:1.2.0'

结果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 Activity 的包。 所以这...

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

应该是……

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

可以找到可能的包名here .它们包括:

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