how to close TWA

[mohit1993]

Hello,

I am not able to exit TWA's activity(WebView), i have a scenario where user needs to send feedback with phone shake gesture, i will listen sensor in native code with a service, i need to open a UI(Activity) for user where user can see feedback form , but i am not able to open new activity as TWA was already being launched and TWA's view is in foreground.

I have a custom android activity which have code to launch TWA : basically i don't have TWA's Launcher activity as my launcher activity in AndroidManifest instead i copied code from TWA's Launcher Activity to my android launcher activity to launch TWA. Even if i finish my only activity which launches TWA, TWA is still in the foreground. I need help here whether i should be able to close TWA Web view, or i should be able to launch a new activity on top of TWA. I am not able to use my only activity(Launcher Activity) as it is also in onPause state due to TWA's view.

public void launchTWA() {
        try {
            this.twaLauncher = new TwaLauncher(this);
            this.twaLauncher.launch(twaBuilder, customTabsCallback, this.splashScreenStrategy,
                    () -> this.browserWasLaunched = true, this.twaHelper.getFallbackStrategy());
            if (!WhiteBoardLauncherActivity.chromeVersionChecked) {
                ChromeUpdatePrompt.promptIfNeeded(this, this.twaLauncher.getProviderPackage());
                setChromeVersionChecked(true);
            }
            (new TwaSharedPreferencesManager(this))
                    .writeLastLaunchedProviderPackageName(this.twaLauncher.getProviderPackage());
        } catch (ActivityNotFoundException e) {
            finishActivity();
        } catch (Exception e) {
            }
    }

Trying to understand better the issue. Is this something that only happens when using the WebView fallback? Only when rendering using the browser, or both?

Hi folks, I have almost the same use case. I have a foreground service running in the native part of my app while the pwa is running in a CCT instance. The Activity which have launched the CCT extends com.google.androidbrowserhelper.trusted.LauncherActivity

My need is to finish the CCT and exit the app, here is my code in my foreground service :

stopService(intent);
((Activity) LauncherActivity.currentContext).finishAffinity();
System.exit(0);

In the logcat I see the app being destroying, but the CCT is still open and the user can still interact with it

Can you help me please ? Thx

Same. The TWA launches in foreground.... but there's no way of closing the TWA. Clicking back button sends it background. I actually want the app to close.

This seems similar to crbug.com/925539. unfortunately there is no way to close the foreground CCT. I'll mark this as feature request.
