am 4574df0c: Merge "Reducing WebView navigation timeout for accessibility." into jb-mr1-dev

                "javascript:(function() { %s.onResult(%d, %s); })();";

        // Time in milliseconds to wait for a result before failing.

        private static final long RESULT_TIMEOUT = 5000;

        // Based on recorded times, we have found that in a complex real-world

        // web app (such as the desktop version of Gmail), there can be spikes

        // of ~2600ms in the worst case. These are temporary spikes and are not

        // repeatable; GMail eventually settles down to around ~60ms. The

        // longest duration that is consistently repeatable is ~300ms when

        // loading extremely large plain text documents in WebView.

        // If this timeout hits, the navigation is considered to have "failed",

        // meaning there is no content. Since the longer spikes are one-off

        // events triggered by the page loading and itself running a large

        // amount of JS, subsequent runs would succeed, so the worst impact

        // is that the first run will look like it had not loaded yet.

        private static final long RESULT_TIMEOUT = 1500;
