[Captivate General] WhatsAHinduToDo:
printf("Hello XDA!");

I haven't posted much, but I've spent a lot of time on these forums and flashed a few custom roms on my captivate as well. I'm a final-year computer science student and now I want to jump into the android source code.

I have some operating systems experience, I took the OS class at my university and ended up with a C (more due to external factors than the difficulty of the course).

Does anyone have any tips on where to start or how to make sense of the very large source distribution? I installed ubuntu, set up my repo, and downloaded the AOSP FroYo and Gingerbread sources. I think that, for my first project, as a way to learn about what goes into making a ROM, I want to post the AOSP FroYo source to the captivate and just have a pure AOSP build running on my phone. Can anyone point me to some resources or information to help me get started?

Thanks a lot!

[Captivate General] WhatsAHinduToDo:
Actually I meant more like resources about how the android source is laid out, which source files to edit to make a custom rom, which source files control which parts of the phone, etc. I've already seen the guide you linked to putting together a custom ROM.

And even if someone is working on AOSP Froyo, I want to do this to learn about how the Android OS works so that I can go on to developing better ROMs

Hello all.

I have 500 gb ntfs hard disk. Originally adam doesnt detect it.

I tried stephenH 'perf update' and it got detected, but this update screwed my 16 gb internal memory card.

So i flashed back to original eden and then installed the recently updated version by stephenH 'perf update new'. It does not have ntfs kernel..

So i formatted my hdd to exFAT... Bt it doesnt get detected.

I hv win 7 in my laptop and by default i was not getting to format it as fat.

So i formatted with 'hp usb format tool' into FAT32....

Bt its still not detected.

Any ideas.... What shud i do to get it detected.

Thanks

Hi,

I'm using an Android HTC Desire since one year and a Folio 100 Tablet since december.

I really enjoy android and I want if possible to start learning "how to cook rom".

Is there somewhere some post, website, step by step starting help ?

Regards

Harlock
[Android Software Development] LUC@X:
Shure, just look at SDK (software development kit) at the Android's home page; why do you want to cook a ROM? isn't your devices working properly or without full functionality?
[Android Software Development] harlock999:
My first point is trying to make a Honeycom rom for my Tablet (under 2.2)

I am a noob to rooting a nook color and was wondering which image would be recommended at this time? It is my wife's nook color and she is got 1.1.0 update on it and we are running windows xp on the desktop right now so any input would be greatly appreciated. Oh and she has a 32gb microsdcard in the nook that is blank.
[Nook Color General] junkrobot:
If by image, you mean Andrioid version, I'd stick with rooted stock Eclair, if I were you. It's all well and good to expermient, but it can be rather time-consuming.

Personally, I'd say to use AutoNooter and follow the instructions on NookDevs. Make sure to use the right version (1.1.0 in your case) and good luck!
[Nook Color General] crhennes:
Thanks for the input
[Nook Color General] xdabr:
FYI, it was completely non-obvious to me until I asked here, but apparently you can root (or not root) the stock OS and alternately boot off an SD card at your whim.

I am really liking the Monster Root Pack from thecubed:

Rooted one of the NCs I have from 1.1.0 and have found it extremely stable and all facets working beautifully! Have some minor issues with Dolphin ND but prefer Opera anyway. Burnt the image to a 2GB Class 2 mSDHC only installing the root and GApps. Installed CWM later. thecubed did some sweet work on this. Almost foolproof IMO.

Give it a whirl.
[Nook Color General] JLCollier2005:
I'll tell you I read through these forums for 4 days before I finally rooted my nook. Used Auto nooter and then realized that I bought this thing for full use as an Android tab and the next day I looked into CyanogenMod 7. After 2 days of trying to do the dual boot (sd card boot), I gave up and finally just flashed CM7 to the internal

Yesterday a friend of mine brought his nook to me. Saw how much I could do that he could not, and had me root and flash CM7. It is so easy if you follow the instructions on the CM nook wiki page! Including time to format the SD card (which takes the longest) and install, it was less than a half hour before he was up and running as a full tablet. THe instructions, although they seem brief, are great there. Follow it to a key and remember to ask questions if needed.

hi everyone. i just had a question about donations. i was just wondering what is an "acceptable" donation to a developer that either creates or modifies icons/games/kernels etc. for you. i don't want to insult the developer, but at the same time, i'm unemployed and i'm not exactly rollin' in the money either. any suggestions would be greatly appreciated and thanks to all the developers.
[General Questions and Answers] Dirk:
I'm sure donations of all sizes are welcomed. Most people don't bother, which is a shame, so even £1 (Sterling) would be a good start.

I generally go with £10 per donation for the software that i use.
[General Questions and Answers] Dark3n:
Really depends on how much work he put into it for you.

But as those are donations, not payments.

Anything should really be fine.

I would do something between 5-15$ if you dont have alot.

For me the gesture really counts a lot too. That someone was so thankfull for my work, which he got for free, that he felt like donating something :).

Makes me feel happy :).

I'm having a serious problem on my Mini 10! I installed the BETA MINICM 2, but the battery from 7 am until 12:30 pm falls to 65% ... Is that normal?

If not, how can I fix this?

And if you have a better ROM for my, what would it be? For use only listen to music
[Sony Ericsson XPERIA X10 Mini] Klaas1241:
Looks normal. depending on what you do with your phone.

Normally it should last about 16 hrs normal use.

[Nook Color General] EverythingNook:
I only have 5 widgets, and my brightness is also low as possible. I have wifi off when i don't use it, but my battery still dies kinda fast. Should i delete cell standby? And what else can i do?
[Nook Color General] everalm:
You really should define "kinda fast" so folks can answer objectively
[Nook Color General] EverythingNook:
Well just playing games like angry birds for 20 minutes it drops like 10%
[Nook Color General] HotShotAzn:
1) Which ROM

2) What widgets

3) What are you using to monitor battery drop

10% in 20 minutes (screen on, in use) is pretty aggressive.
[Nook Color General] EverythingNook:
1. Stock with launcherpro

2. Typoclock power control beautiful battery google search and music

3. Beautiful battery
[Nook Color General] HotShotAzn:
What drain are you seeing with screen off/idle?
[Nook Color General] EverythingNook:
with the screen off for about 5 hours i saw a 21% drain.
[Nook Color General] muzzy996:
Drop the widgets and livewallpaper if you've got it. Retest standby.

If you're getting high battery drain during standby your nook isn't going into deep sleep and chances are that background overhead translates to poor efficiency at idle when the nook is on as well. Couple poor idle efficiency with CPU intensive work while in use and your overall battery life is terrible.

If you're forcing the nook to stay out of deep sleep for other reasons like keeping wifi alive then you may be stuck with living with some sort of elevated drain but you can minimize it by reducing idle overhead by keeping widgets to a minimum and refraining from using live wallpapers and other background services that aren't critical.
[Nook Color General] distortedloop:
Tacking on to here rather than starting a new thread...

My Nook Color rooted, but still on stock ROM goes from 100% charge to 25% in about 8-9 hours with zero usage. Obviously something's going on (I suspect it's that I have Advanced WiFi sleep policy set to never and am away from WiFi), but no other widgets running. I do have Google Voice app installed.

What I'm curious about is what would normal standby battery drain be? What would be typical after 8-9 hours of just sitting untouched in my brief case?

Thanks in advance!
[Nook Color General] muzzy996:
If you suspect it, disable it and see. I'm thinking that would be a prime suspect.

I believe typically overnight you should see less than 10% drain.
[Nook Color General] KitF:
In CM7 at least, in Spare Parts you can see what uses the battery while the NC is asleep.
[Nook Color General] hxh103:
do you have it overclocked? if so, have a profile that clocks it down to 300mhz when the screen is locked
[Nook Color General] distortedloop:
No, not yet. It's 100% stock, other than rooting and downloading apps. I'm going to put SystemPanel on it and see if it gives a clue.

I've got a good idea of how to track down battery issues on most android devices, I was just mostly curious what the typical drain other rooted users saw was.

Thx for the suggestions to all.
[Nook Color General] khaytsus:
Good lord, this isn't going to help anything. Normal Nook Colors on the stock ROM (and kernel....) use about .2%/hr in standby.

Clearly something is running wild on this guys NC, and needs to look at Spare Parts. Install it from the market.

System Panel as well as other tools can help as well.
[Nook Color General] distortedloop:
Okay, I'm a pretty smart guy usually, but I'll publicly put on the dunce cap and admit to my ignorance on this one.

System Panel actually showed some amazingly good lack of drain with all my apps running.

The reason my battery was so low when I checked it each afternoon is because even though I thought I was charging the thing over night, I wasn't. I was using a regular micro-usb cable for my phone to plug the thing in most nights.

Turns out the Nook Color has an extra deep micro-usb receptacle and requires a better endowed male plug to get it charged properly.

Lame...

(Lame of me, but also lame of B&N to make such a design decision. What were they thinking? I HATE proprietary connectors.)
[Nook Color General] khaytsus:
Extra WIDE, not deep. And there's good reason ;) USB standards are .5A over the typical 4 pin connection. The B&N cable has FOUR extra pins, delivering the other 1.4A of power.
[Nook Color General] danger-rat:
Extra deep. Two stages...

First stage 5 pins, second stage 12 pins...
[Nook Color General] Krazypoloc:
Yup same cable as my Droid2 and Droid before it....
[Nook Color General] Pinoy8125:
Does this mean we can use the droid2 and droid's cables as alternatives?
[Nook Color General] distortedloop:
Thanks for the extra info about the additional voltage; so it will charge much faster this way? (rhetorical question)

I still am annoyed at yet another non-standard cable that I'll have to carry around with me when I travel to keep various devices charged, but in the scheme of things it's a minor annoyance. Stuff like this should be standardized, IMHO.

And it's extra DEEP, not wide. ;) It's the same width as a standard micro-usb cable or I wouldn't have been able to stick my phone's charging cable into it at all, but I was able to, it just didn't go in deep enough to charge at all. On the flips side, the B&N cable fits into my phone, but only inserts half-way deep; if it were extra wide it wouldn't fit into my phone at all.
[Nook Color General] muzzy996:
People are describing it as extra wide because at the tip there are more conductors visible and less plastic shielding so internal to the outer metal shape it appears wider. Yes externally its the same width and thus other microUSB cables fit into the NC.
[Nook Color General] davidfig:
Don't know if this helps

Don't know if this helps. Last night I put MIUI Android on my nook. This morning before work I noted a 100 charge and went to work. When I came home about 11 hours later, it had 99% charge.

What is MIUI doing right that others are not? Hope this helps someone.

[Android Apps and Games] ukanth:
Nice application, Small bug to report,

Steps to reproduce:

1) Install, open app and start service

2) Add widget to home screen

3) From notification start the app

4) Stop the service

5) Repeat step 3

6) Start the service

Now the actual percentage is showing differently. I can reproduce it on my HTC desire(MIUI) twice.

Hope you'll have a look into that.
[Android Apps and Games] :
Thank you for the feedback.

When you say "stop the service", do you mean stop it manually?, i.e. force close it from the Android settings menu, or stop it by clicking the stop monitoring button in the activity itself ? When the service is stopped using either method the Notification is removed, so I can't "Repeat step 3", as per your instructions. But I can open the activity from the widget to re-start it. But I don't see any problems. The percentage re-displays as expected.

Also, what do you mean by "showing differently", do you mean the widget is displaying a value different to the notification icon ? Or the value seems to change after re-starting the service ? It's highly likely that in the time it takes to go through these steps that the battery level drops by 1%.

Just trying to figure out exactly what you mean, as I can't reproduce any bugs, yet.

Thanks.

Okay, I'm running Stock Mysense 2.2.1, rooted, S=off, super CID, and unlocked SIM. I got Clockworkmod 3.0.0.6 here (http://xdaforums.com/showthread.php?t=944681), and I installed Faux123's OC kernel from here (http://xdaforums.com/showthread.php?t=941141). So far, not even a hiccup.

I didn't like the stock battery bar, and I saw that pack had made some battery icon mods, so I decided to install one from here (http://xdaforums.com/showthread.php?t=852013). Even though the mod was designed for Mysense and Mysense ports running CWM pre-3.0, I read in the CWM 3.0.0.6 forum I posted above that 3.0.0.6 was designed to bridge Gingerbread CWM with 2.5.1.4, since it runs ext3 and ext4 (at least I that's what I thought it meant).

First, I tried flashing CWM 2.5.1.4, which it did successfully, but on reboot, I got the red ! symbol, so I went back to 3.0.0.6. When I try to install pack's mod using 3.0.0.6, I get the following messages:

Finding update package...

Amend scripting was deprecated by Google in Android 1.5.

It was necessary to remove it when upgrading to the ClockworkMod 3.0 Gingerbread based recovery. Please with to Edify scripting (updater-script and update-binary) to create working zip packages.

I'm not really sure what I did wrong, anyone have any ideas? Any help you can provide is very much appreciated.
[myTouch 4G Q&A, Help & Troubleshooting] TrueBlue_Drew:
The reason you get that error is because the update script is made with a amend script rather than a edify script. In order to flash something with the old script you must first flash the 2.5.1.2 version of CwM recovery. Then after you flash your mod you can flash back to 3.0.0.6 recovery. Hope this helps clarify it for you :)
