App Crashes On Email Verification (Sign Up)

[ericdecanini]

During a community testing session we found that during sign up that upon verifying your email, when reaching the login captcha fragment, the app crashes.

I tried reproducing this issue myself (on matrix.org) but to no avail. It's possible that this is dependent on the homeserver.

What this meant for the user however is they could not sign up at all

going to downgrade the severity of this as it's caused by the device not having a webview installed

my suggestion would be to catch and inform the user about their missing WebView/Browser

according to SO the webview feature check isn't reliable as a user may still disable the webiew/browser, the workaround is to try and instantiate the CookieManager and catch any exceptions

val hasWebView: Boolean = kotlin.runCatching { CookieManager.getInstance() }.isSuccess
