无法理解如何在应用程序中打开简单的TWA(使用AndroidX) [英] Cannot understand how to open a simple TWA inside an app (using AndroidX)

问题描述

我正在尝试在我的应用程序中打开TWA，并进行了2天的研究.

I am trying to open a TWA inside my app and have researched for 2 days.

我已经设法创建了一个TWA应用程序，不必大惊小怪，只需编辑清单即可.

I've already managed to create a single TWA app, no fuss, just edit the manifest and a few things more.

现在我需要拥有自己的应用程序-假设该应用程序首先具有启动屏幕活动，然后在应用程序内部打开TWA. 例如，是否可以通过简单的启动屏幕活动在我的应用程序内启动TWA?

Now I need to have my own app - let's say the app has a splash screen activity at first which then opens the TWA inside the app. Can I launch a TWA inside my app through a simple splash screen activity, for example?

我确实尝试使用CustomTabs的方式，但是它说它已被弃用，而改用TrustedWebActivityIntentBuilder，但是我重复了0，关于如何使用它的零文档！

I did try to use CustomTabs way, but it says it is deprecated and to use TrustedWebActivityIntentBuilder instead, but there is 0, I repeat, ZERO documentation on how to use that!

Android开发文档太可怕了.除其他事项外，文档指针已过时. (阅读其频道上的视频，这些视频链接到对

Android development documentation is horrible. Among other things, the documentation pointers are out-dated. (Read videos on their channel linking to guides that are no longer valid for what is discussed in the video itself)

我找到的最接近的东西是示例项目.这使用了大量令人讨厌的东西，使该方法适应我的应用程序变得完全无用.它还利用了仅为该项目创建的无数个自定义类/助手，这使我进行了无休止的复制粘贴马拉松竞赛，以发现其中每个对象都需要复制转到项目.

The closest thing I found was this sample project. This uses a shocking number of deprecated things rendering the adaptation of that method into my app completely useless. It also makes use of a countless number of custom Classes/Helpers created just for that project, leading me to a never ending marathon of copy-pasting each one of them just to find out that inside that one there are more that need to be copied over to the project.

推荐答案

经过一再的尝试和错误，我设法在应用程序内部启动了TWA.请注意，这与WebView不同，它只是在应用程序堆栈上启动活动.

After a lot of trial and error as always I've managed to launch a TWA inside the app. Note that this is not like a WebView, it merely starts an activity on your app's stack.

以下是我的活动的代码:

The following is in my Activity's code:

final static String PACKAGE_NAME = "com.android.chrome";
final static String BASE_URL = "https://your.website.com";
CustomTabsClient mClient;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_launcher);

    CustomTabsClient.bindCustomTabsService(this, PACKAGE_NAME, getConnection(BASE_URL));

}

private CustomTabsServiceConnection getConnection(final String url) {

    return new CustomTabsServiceConnection() {

        @Override
        public void onServiceDisconnected(ComponentName componentName) {
            mClient = null;
        }

        @Override
        public void onCustomTabsServiceConnected(
            ComponentName name,
            CustomTabsClient client
        ) {

            final Intent intent;
            final CustomTabsSession customTabsSession;
            final TrustedWebActivityIntentBuilder intentBuilder;

            mClient = client;
            mClient.warmup(0);

            if ((customTabsSession = mClient.newSession(new CustomTabsCallback())) == null) {
                return;
            }

            intentBuilder = new TrustedWebActivityIntentBuilder(Uri.parse(url))
                .setToolbarColor(Color.parseColor("#ffffff"))
                .setNavigationBarColor(Color.parseColor("#ffffff"));

            intent = intentBuilder.build(customTabsSession);

            startActivity(intent);

        }

    };

}
