androidWebView.page: Cannot read property 'mainFrame' of undefined

[SirCameron]

Hi

I'm using the playwright-android package on an emulator.

Running this returns the above error:

const [device] = await android.devices()
        console.log(`Model: ${device.model()}`)
        console.log(`Serial: ${device.serial()}`)

        {
            // Launch an application with WebView.
            await device.shell('am force-stop org.chromium.webview_shell')
            await device.shell('am start org.chromium.webview_shell/.WebViewBrowserActivity')
            // Get the WebView.
            const webview = await device.webView({ pkg: 'org.chromium.webview_shell' })

            // Fill the input box.
            await device.fill({ res: 'org.chromium.webview_shell:id/url_field' }, 'https://google.com')
            await device.press({ res: 'org.chromium.webview_shell:id/url_field' }, 'Enter')

            // Work with WebView's page as usual.
            await webview.page()

I have not been able to find anything about this around the web and the android-playwright package has no documentation of it's own. Would using webview.page() be the correct way to interact with elements in a webview?

Also, where can I find information/documentation on AndroidSelector?

Thanks in advance for any help.

Hi, the playwright-android package is deprecated, see here for an up-to-date example: https://playwright.dev/docs/api/class-android

[SirCameron]

thanks @mxschmitt . I tried it using the android class from the playwright package and it simply hangs... no error, nothing. Running the webview example on the page you provided, it never logs out the page title. simply hangs on webview.page().

[mxschmitt]

where does it hang? Could you try setting the following environment variable, this should give you more debug logs: DEBUG=pw:android

[SirCameron]

Thanks, as I've said "simply hangs on webview.page()". Until it finally times out. I have been running it with the DEBUG=pw:android env variabled, but it hasn't given me anything valuable.

this is the output:

Which android sdk version are you using in your emulator? We use the following: create avd --force --name android30 --device "Nexus 5X" --package "system-images;android-30;google_apis;x86"

[SirCameron]

Thanks @mxschmitt I created a nexus 5x device with android 30 and it's working now.
