what are these "about:debug" options? - Nexus One Q&A, Help & Troubleshooting

What is "tracing" and what is "light touch"? Thanks
Also, when I choose desktop, if I exit the browser then next time I open it it doesn't act as though desktop is set, but when I go to settings desktop is still selected I just have to press it again. Shouldn't it stay unless I uncheck it or maybe clear browser cache, etc? Not a huge deal just a question I thought of while typing the main ones above...

I imagine that light touch makes the screen more sensative when your on the browser. Just a hunch though.

That might be cool. I went ahead and checked it to see, nothing noticeable so far

I just did a quick grep of the Browser source tree, and it looks like those settings aren't currently being used for anything.

browser not using cache?

Just out of curiosity, does anyone know why our browsers have to reload the page even though you are just going "back" one page. For example, if I visit Gizmodo, then go to engadget, then back to Gizmodo, my browser has to reload the page instead of using the cache. It seems as if the cache is barely used (granted the reload is a little quicker, but not much).
Is there a tweak or program that can make this better? It is really frustrating, especially if you are trying to browse a page and accidentally hit the wrong link, which requires you to fumble for stop and oft times requires a reload (this is one reason I miss the Hero browser, because it had a stop button in the address bar).
Hmm, I've noticed this as well. Perhaps Android thinks you need to refresh the page? I know with apps like Opera Mini, pages back (somewhere around 10) are completely stored which is a very nice feature, but as to why Android doesn't do this, is a mystery .
I know the larger files, like images and chunks of text, are saved to the cache, but not whole pages. That would get pretty big after a while, and would slow down the browser because of access times. It's the time the Browser takes to draw the page is what's creating the lag. Look at Opera Mini again, the page loads instantly because it's zoomed out first, then you zoom in.
try "steel" browser.
@ phuthanvinh: I have tried "Steel", but it really isn't any better.
@lukekirstein, yeah, that is one nice thing about Opera. It loads cached pages almost instantly in most instances. When I need quick information, I always turn to Opera. If I want to browse for pleasure, then I use the Android browser.
It would be awesome if a Developer could implement some type of Webkit add-on that forces cache of the whole page.
I just wonder if the "lag" is not caused by redownloading, but rather stems from Android using software-based graphics decoding instead of using the onboard graphics chip. At least that is what I have heard.
I have the same issue and it's very annoying when I'm using google reader!
Have you find a solution?
Does anyone have a solution to prevent android browser to reload pages already load in a tab after I come back from another tab?

Browser hogging internal phone storage?

Ever since I updated my nexus to Froyo, when I'm using the browser itll start to take up all of my available memory causing me to get the low storage warning and sometimes stop me from getting text messages. The only way to free back up the memory is to go force close the browser, which is sometimes using up to 80 mb of data. Ive already tried a factory data reset and also went into the recovery and wiped and clear the cache. I never had this problem in 2.1 and its really annoying. anyone got any ideas? thanks.
forceclosing the browser wont clear up cache.... scroll down instead of forceclosing, and hit clear cache. dont do it through recovery
I am having this problem too D:
Yeah, the browser doesn't seem to limit cache, although I've never seen it use 80M. Most I've seen is 7M. I just clear cache through the Applications list, although in Froyo you can do it directly in the browser now.
if you visit the google forums, the android team has changed the browser in 2.2 to cache the pages you have open in your browser much more aggressively, so that when you go back to the browser the phone doesnt need to refresh the network and reload the page. i posted a link to the google topic before. but what this means is that the browser now takes up huge amounts of space as time goes on. killing it does bring back the space. personally i like this change, but i can see why it might suck for some people.

i posted against this issue, because i happen to like what they did to the new browser. god forbid they go back to the old way, it was not good.
I agree, the browser is better this way in some regards, but it needs to LIMIT what it does... If you don't manually clear cache it'll easily take 8+ megs of storage!

but its not the cache, its just a temporary storage usage. if you force close the browser, it regains back that storage. at least for me it does. my actual cache in the browser never changes, and hovers around 7mb.
Aaaand we're not using A2SD why???

Ah, sorry, I got off topic then.. I was talking specifically about the browser cache, which for me varies between 4-8.5M it seems.. and I clear it because otherwise I'm <20M

Simple solution
Friend was having the same issue but this was pre-froyo.
Found out that after viewing articles on the news and weather app and also viewing webpages she was just hitting the home softkey to return to the main page. This was causing new window after new window of fully loaded websites to be cached out of memory and into storage.
Although i agree there should be a caching limit on the browser there should also be an effort from the end user to close the unused windows when done (easily done through the windows menu). Also after using the news and weather app and any other app that uses the browser to display pages, it should be good practice to use the back button and not the home key.
I've always done that and now my girlfriend does it and guess what... its not an issue anymore.

Except that you can't use the back button in the browser if you've been browsing a lot, you'll be going backwards through a bunch of pages. And if you've logged in, you can't go past that at all as it'll want to repost data etc...
One could close the window I suppose, which would load a default homepage, then go back, but that's tedious.

Tedious? Thats almost as bad as that YouTube review of the Nexus where one guy said he had to move his hand "All the way up to the top of the phone" just to switch it on. (Surely we've all seen it?)
I wouldn't say tedious, just something to get used to. Sadly Google aren't quite there with their Google MindReader beta for Android but until then menus and manually closing windows work just fine ;-)

Steps to properly exit browser
Menu button
Select Windows option
X on all open Windows
Back Button
Not exactly "move hand to top of phone".
And again, my major complaint is about the lack of a limited browser cache, ie: html, css, images, cached for later reload. It grows over 8M, that's really too much IMO. Should be able to limit it, in which case I'd likely limit it to 2-3M myself and see how it worked out.

Actually I do that quite a bit. But you don't even have to. After you close all windows, it defaults to open a last page (Google home in my case), then just hit home cause there's nothing left to cache anyway, so back button or home button does the same thing, makes no difference.
hmm in my case it's also not the cache which makes the problems, but the "Data" of the browser app.
It easily exceeds 28MB!
And cache is only at 600kb, so clearing cache doesn't help.
Clearing the data helps. but it will delete all your bookmarks and other settings which is bull****.
Force closing the browser didn't help too (it helped in the past but interestingly not today).
Browser can not be installed on sd card. System updates can not be installed on external memory.

What? From apps, manage, all, find browser. Clear cache there. That does not clear up your 28M in ram?

[Q] Some questions about a newly rooted NC

Okay, so far, mostly good, but have a few questions I'm hoping someone can help me with. I've used autonooter for 1.0.1 (after upgrading the firmware to 1.0.1 of course) and also disabled the cell and telephony services by renaming them to .OLD.
1) How do you get the web button to actually launch a different browser than the stock one? I've installed Dolphin and Dolphin HD and set each in turn as the "default browser" in their settings and mutliple times after multiple reboots. But when I use the 'web' button on the NC menu, it always takes me to the stock browser. What am I missing here?
2) I don't want the 'email' app running. I don't need it, don't want it (have web-based email for everything I need), but can't figure out how to keep it from running. Or maybe I just don't understand what it does? Can someone explain either the necessity of email or how to shut it off?
3) I also notice something called 'social' running. Have no clue what it is and figure I probably don't want or need it running. Can anyone explain this one for me (why I need it or how I shut it off)?
4) Has anyone found a workaround to replace needing a reboot to make installed apps show on the extras page?
5) How to you manage the 'extras' page? As the amount of installed apps grows, the page is becoming more and more difficult to use. Is this something simple I'm missing?
6) I noticed the open book/recently reading icon doesn't work now unless I use the stock launcher. I've read that all you have to do is run it once (then go back to softkeys or whatever) and the button works, but also read that disappears each time you restart (see above). Is there any workaround to having to do this?
7) Is is possible to remap the other keys? For example, make the open book button do something else? Or the keys in the menu that comes up?
8) Lastly...what size microSD card does everyone recommend? Seems anything over 4GB would just be a waste.
Thanks to anyone who responds!

Don't use the Web button. Launch the browser.
Set it to sync manually. Fixed.
Ignore, part of B&N
Use a launcher. ADW Launcher works great.
See above
Pretty sure if you hit the softkey for the B&N apps, hit Library, then tap the Book icon you're talking about it will launch the last book. 2 extra taps.
Those aren't keys, and let's just say no.
Anything under 8G ain't going to have much music or data. Up to you.
Thanks khaytsus but...
1) When you say "launch" the browser, from where do you mean? I tried the web icon in Zeam and it does the same thing. Are you saying the only way to use an alternate browser is to open extras or apps and launch it? So 'set as default' doesn't work on any of these browsers?
2) I set up the email check frequency to never but it still runs once rebooting.
4) Tried using the applications icon in Zeam and ADW, but it still doesn't show newly installed applications until a reboot.
6) Thanks for the suggestion, but the book button still doesn't work.
Any other thoughts?

4/5 Theres no readin to use the b&n bar. Use the app drawer (from adw or zeam) to launch your apps. In the app drawer hold down your browser (use dolphin hd or another, the default is no good) icon and it will make a shotcut on the main screen. You dont really ever have to use the default bn stuff.

[Reference] Firefox Hacks

Firefox Hacks
Desktop UA:
To set Firefox to use a Desktop UA by default, type in about:config in the address bar and then click on Add a New Setting, select String, and enter general.useragent.override, click ok and enter:
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:23.0) Gecko/20130406 Firefox/23.0 for a Firefox User Agent.​
Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1468.0 Safari/537.36 for a Chrome User Agent.
Mozilla/5.0 (compatible; MSIE 10.6; Windows NT 6.1; Trident/5.0; InfoPath.2; SLCC1; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; .NET CLR 2.0.50727) 3gpp-gba UNTRUSTED/1.0 for a Internet Explorer User Agent.
Finally type in agent in the search box and find general.useragent.enable_overrides and toggle it to true
Make Firefox Faster​Enable Pipelining:
Browsers are normally very polite, sending a request to a server then waiting for a response before continuing. Pipelining is a more aggressive technique that lets them send multiple requests before any responses are received, often reducing page download times. To enable it, type about:config in the address bar, type in pipelining in the search box and hit enter. Find network.http.pipelining.agressive and toggle it to true and network.http.pipelining.maxrequests and click on modify and change it to 50(use a lower number if you have a low speed connection)
Render quickly:
Large, complex web pages can take a while to download. Firefox doesn't want to keep you waiting, so by default will display what it's received so far every 0.12 seconds (the "content notify interval"). While this helps the browser feel snappy, frequent redraws increase the total page load time, so a longer content notify interval will improve performance. To enable it type about:config in the address bar and click on Add a New Setting select Integer Type content.notify.interval as your preference name, click OK, enter 500000 and then click on Add a New Setting and select Boolean create a value called content.notify.ontimer and set it to True
Faster loading:
If you haven't touched your screen for .75 second, then Firefox enters a low frequency interrupt mode, which means its interface becomes less responsive but your page loads more quickly. Reducing the content switch threshold can improve performance, then, and it only takes a moment. To enable it type about:config,in the address bar and click on Add a New Setting select Integer Type content.switch.threshold, as your preference name, click OK, enter 250000 (quarter of a second)
Increase the cache size:
As you browse the web so Firefox stores site images and scripts in a local memory cache, where they can be speedily retrieved if you revisit the same page. If you have plenty of RAM, leave Firefox running all the time and regularly return to pages then you can improve performance by increasing this cache size. To enable it type about:config,in the address bar and click on Add a New Setting select Integer Type browser.cache.memory.capacity as your preference name, click OK, enter 18432
Enable TraceMonkey:
TraceMonkey is a new Firefox feature that converts slow JavaScript into super-speedy x86 code, and so lets it run some functions up to 20 times faster than the current version. To enable it type about:config, in the address bar and then type jit in the search box and hit enter. Find javascript.options.methodjit.chrome and toggle it to true and javascript.options.methodjit_alwaysand toggle it to true.
Cache:
Unfortunately Firefox collects copious amounts of data and there is no way to prevent it.
This was adapted from: http://www.techradar.com/us/news/software/applications/8-hacks-to-make-firefox-ridiculously-fast-468317 and http://useragentstring.com/pages/useragentstring.php​
This makes Firefox blazingly fast on my tablet and so far every website works perfectly.
To save settings for easy restoring navigate to data/data/org.mozilla.firefox/files/mozilla/widlm1lw.default/ and make a copy of prefs.js
Some more possibly useful settings:
[FONT=&quot]
Type about:config in the address bar, type in browser in the search box and hit enter[/FONT]
browser.download.manager.displayedHistoryDays set to 1 (set to whatever you like)
browser.enable_automatic_image_resizing set to true
browser.enable_click_image_resizing set to true
browser.helperApps.deleteTempFileOnExit set to true
browser.history_expire_days set to 1 (set to whatever you like)
browser.history_expire_days_min set to 1 (set to whatever you like)
browser.zoom.full set to true
browser.zoom.reflowOnZoom set to true
browser.cache.disk_cache_ssl set to false
If anyone finds any more useful settings that can be changed or settings that work best, post them here.

It's rather ironic, that this is the only real desktop browser on android, yet most of the desktop settings aren't enabled or set by default. This is only browser that I have ever used that I can use all day on flash heavy sites and never crash. I've only had one FC in the past month.

Yeah FF is hands down a quality browser, I'd be using it on Desktop if it wasn't so weird about my Cookies (never keeps me signed in on Forums[XDA] etc)
But I can't believe these options are just as usable on desktop, and yeah, even without these settings enabled I must say FF has never crashed on me on my tablet (even with flash heavy sites as you say).
Whereas Chrome just stutters, cries and gives up.
Boat just freaks out and FC's
Dolphin just isn't my pick.
Opera I don't like at all.
SO WEEEE Thanks for these tips my friend !

Thanks for the post, very interesting.
I applied your tips to firefox running on my Nexus 4, but I did not see much of an improvement. Just doing some casual/typical browsing that I would normally do it felt almost the same as before without the tweaks, although I wasn`t doing any timing with a stopwatch or anything of that matter so I can`t say for sure that there wasn`t an improvement. Maybe these tweaks would benefit lower/older end devices more than the newer high speed quadcores.

Its really noticeable when you start with a fresh install of Firefox with no data, once Firefox starts collecting data it starts really slowing down. Firefox really needs to deal with this data collection issue. For me it collects over 100mb of data in just a couple of weeks despite clearing everything from within the app. I don't think most of settings affect Firefox's performance if its not being used with a desktop user agent since that is handled completely different than if you're using the default android user agent.

This is not true, general.useragent.enable_overrides has no effect on general.useragent.override (which is always enabled) and instead affects overriding the User Agent on a per-domain basis as described here.

You should tell people the integer is the cache size in KB. My config already had this setting and it was set to 1024. According to mozillaZine, the default is set according to RAM size but as mine defaulted to 1024, perhaps this is different for mobiles. Setting it to your apparently random value of 18432 could work, but after reading the tweaks page you referenced and mozillaZine, I opted to set it to -1 which should let Firefox decide according to how much RAM I have and if it follows the table in mozillaZine, will make a substantially bigger cache than you suggested.
Thanks for bringing my attention to these useful features.

Strange issue with App Launch (App Power Management)

Hi, I have noticed something strange with the settings in Settings > Battery > App Launch
I have turned this off due to previously asking about not receiving notifications, this did fix that issue. i then found the 3 dots in the top right of that screen and there’s an option called manage manually and as would be the case most apps have 3 ticks next to most of the apps, there are a lot that, don't have ticks though, i would assume all should have ticks if i have set the auto manage to off?
I then thought i would try enabling manage automatically again and then manually switching only the apps i want to run freely to do so, this all seemed to go fine and as i tapped on each one i got the option to turn on auto launch, secondary launch & run in background. So once i have done all the apps i wanted i went out of them settings then went back in and it has completely turned off auto manage for everything.
It seems that when you turn off this setting it is best to also go to manage manually as well and check the apps that are / are not selected; this does seem to save when you go out then back in.
I must admit i was very impressed with the battery on the p30 until i turned the auto management off and it feels a lot more like my old phone again now, i guess that’s what you have to do if you want notifications though.
Not sure what anyone else thinks of all this?
James
