prefetch download with download service does not happen |
|||
Issue descriptionSteps to repro on Android: 1. Enable kPrefetchingOfflinePagesFeature feature. So a prefetch flag will show in chrome://flags. 2. Enable Prefetch: go to chrome://flags, search for "prefetch", switch "Enables suggested offline pages to be prefetched" to Enabled. 3. Restart. Open chrome://offline-internals. Observe Event Log, it should start logging pipeline work, including Downloader: Start download of ...". Eventually, downloaded pages should appear in Stored Pages list. 3. If you want to repeat (downloads may only be initiated once a day) close chrome and remove the prefetch database: adb shell rm /data/data/com.chrome.canary/app_chrome/Default/Offline\\ Pages/prefech_store/PrefetchStore.db Substitute "com.chrome.canary" for what channel you try.
