The space recorded is the available space beyond the system's minimum free space threshold, with a range between -1000 and 1000 MB. Negative values mean that there is less free space available than the system's minimum, by the given amount. hartmanng@chromium.org src/chrome/android/webapk/OWNERS Records the available space that can be used when installing a WebAPK from Google Play fails after freeing up cache. The space recorded is the available space beyond the system's minimum free space threshold, with a range between -1000 and 1000 MB. Negative values mean that there is less free space available than the system's minimum, by the given amount. hartmanng@chromium.org src/chrome/android/webapk/OWNERS Records the error code when installing a WebAPK from Google Play fails. See go/webapk-install-googleplayerrorcode. hartmanng@chromium.org src/chrome/android/webapk/OWNERS Records whether installing a WebAPK from Google Play succeeded. If not, records the reason that the install failed. hartmanng@chromium.org src/chrome/android/webapk/OWNERS How long it takes to install a WebAPK. The time is measured from the time that the user initiates the install to the time that the Open button is shown in the infobar. This metric is only recorded when install succeeds. hartmanng@chromium.org src/chrome/android/webapk/OWNERS WebAPKs are PWAs wrapped in an Android apk, installed from an app banner or the add to homescreen menu item. This stat tracks WebAPK installation events. eirage@chromium.org hartmanng@chromium.org src/chrome/android/webapk/OWNERS Record whether installing a WebAPK succeeded. If not record the reason that the install failed. eirage@chromium.org hartmanng@chromium.org src/chrome/android/webapk/OWNERS When a user retry installing the WebAPK through the install failure notification, record whether installation was successful. If not record the reason that the install failed. finnur@chromium.org peter@chromium.org src/chrome/android/webapk/OWNERS Records the path that the user took to reach install point for PWAs. This can be via the Install Modal or the new BottomSheet and may involve the in-product help (IPH) showing. Recorded once per install of a PWA, at the time the PWA is installed. hartmanng@chromium.org rayankans@chromium.org src/chrome/android/webapk/OWNERS Records the amount of time which has elapsed from the "install infobar showing" to the "install request being sent to Google Play". This time includes the time that it takes to request the WebAPK token and the time that it takes to compute the hashes for the launcher icon and the badge icon. johnwes@google.com src/chrome/android/webapk/OWNERS Records whether a user is using light theme or dark theme when installing a WebAPK. hartmanng@chromium.org src/chrome/android/webapk/OWNERS Records the error codes when a WebAPK is launched with network failures. johnwes@google.com src/chrome/android/webapk/OWNERS Records whether a user is using light theme or dark theme when launching a WebAPK. Replaced by WebApk.Notification.Permission.Status2 in June 20220. hartmanng@chromium.org src/chrome/android/webapk/OWNERS When a WebAPK receives a notification, log whether it has permission to display that notification. hartmanng@chromium.org mvanouwerkerk@chromium.org src/chrome/android/webapk/OWNERS When a WebAPK receives a notification, log whether it has permission to display that notification. mvanouwerkerk@chromium.org peconn@chromium.org src/chrome/android/webapk/OWNERS The result of a WebAPK notification permission request for the purpose of notification delegation. This is logged when the NotificationPermissionUpdater receives the result from the WebApkServiceClient. hartmanng@chromium.org src/chrome/android/webapk/OWNERS The length of a WebAPK session (launch/foregrounding to backgrounding) in milliseconds. {WebApkDistributorType} hartmanng@chromium.org src/chrome/android/webapk/OWNERS Records WebAPK "Shell APK version" when the WebAPK is launched. The "Shell APK version" is documented in shell_apk_version.gni {WebApkDistributorType} hartmanng@chromium.org src/chrome/android/webapk/OWNERS Tracks the time to splash screen visible starting from the launch of the WebAPK shell (rather than from the launch of Chrome) for new-style WebAPKs. The WebAPK shell displays the splash screen for new-style WebAPKs. This is recorded iff: - This is a cold startup of Chrome. - Chrome has not been sent to the background since launch. - There was no recents entry for Chrome (Android replays intents if a recents entry exists), which otherwise adds noise/long-tail to this histogram. mheikal@chromium.org yfriedman@chromium.org Tracks the time to splashscreen visible starting from the launch of the WebAPK shell (rather than from the launch of Chrome). The splashscreen is shown during postInflationStartup. This is recorded iff: - This is a cold startup of Chrome. - Chrome has not been sent to the background since launch. - There was no recents entry for Chrome (android replays intents if a recents entry exists), which otherwise adds noise/long-tail to this histogram. hartmanng@chromium.org src/chrome/android/webapk/OWNERS Records that a WebAPK was uninstalled. {WebApkDistributorType} eirage@chromium.org hartmanng@chromium.org src/chrome/android/webapk/OWNERS When WebApkUpdateDataFetcher found a valid manifest, record whether the manifest can be used to update the WebAPK. hartmanng@chromium.org src/chrome/android/webapk/OWNERS Records whether updating a WebAPK from Google Play succeeded. If not, records the reason that the update failed. hartmanng@chromium.org src/chrome/android/webapk/OWNERS Records the number of zombie "WebAPK update request" files that the update process failed to cleanup. Recorded for all WebAPKs whenever a WebAPK or webapp is launched. hartmanng@chromium.org src/chrome/android/webapk/OWNERS Records the number of times that a WebAPK update request was queued (i.e. waiting for the WebAPK to be backgrounded) before being sent to the server. hartmanng@chromium.org src/chrome/android/webapk/OWNERS Records the time point when a request to update a WebAPK is sent to the WebAPK Server. eirage@chromium.org hartmanng@chromium.org src/chrome/android/webapk/OWNERS When WebAPK updates with empty or same UniqueId, record whether each of the {LegacyIdentifierType} was the same. eirage@chromium.org hartmanng@chromium.org src/chrome/android/webapk/OWNERS For WebAPK unique ID migration, record whether an update is neede (with non-empty update reason). This only records for the first legacy update that updates the WebAPK from an empty id. eirage@chromium.org src/chrome/android/webapk/OWNERS Records number of unique origins for WebAPKs that have been added to WebappRegistry. This is recorded each time on Chrome startup, after the WebappRegistry is initialized.
