Dell streak 7 Froyo 2.2 Optimizations

Hey developers I would like to know if anyone here would like to help me research and look at the Froyo 2.2 rom with me can someone provide me with its complete source tree? I would like to add dual core support in there for the Dell Streak 7 dont say we need honeycomb 3.0 for that cuz we dont we can program it in there so that the os will activate it and run both processors as one so we dont have to add to the java language for this device we will have to just act as if the other core is the same cpu and same core as the first one it can be simple or hard I dont know if anyone wants to help develop this feature please contact me at [email protected] or skype me Username: Loveless247 or just post on the forum here I would like to put together a nice development team shortly.

You should try adding some punctuation.

Yeah my grammer is horible but my programming is awesome xD

I just ran the Mandro benchmark which indicated my tablet was using both cores...
Development may be useless.

What do you mean I was told it was only a single core operating system the benchmark programs only use one core I can believe this dell are tricky guys and also froyo wasn't built for dual core devices so I believe that benchmarker is wrong.

Download the Mandro benchmark, my Streak scored over double my Nexus One, and it clearly identified two cores.

I can confirm its for dual core

HC lag?

I just got my Dell streak and its the wifi only. Ever since I did the update my DS7 lags after ten minutes. I have to reboot it just to get back to normal. Its not rooted but I have tried but know joy. Any advice?
Sent from my Dell Streak 7 using xda premium

noticeable lag on djsteve R7 (official Dell release, so I imagine stock is bit sluggish too). I went back to HS R6 and scrolls fast menus, screens and webpages..
very nice.

I take it ur device is rooted? Is it a pkg or a zip file.

correct device is rooted running dj steves honeystreak R6 ROM. smooth as butter.

Damn I wish I can get this bad boy roote.

May I offer as a suggestion to try the script mentioned in this rather long XDA thread:
http://forum.xda-developers.com/showthread.php?t=991276
The script changes the settings used by the underlying Android memory manager. I found it quite useful under 2.2 and just as helpful under honeycomb. I most like that it makes the launcher "hard to kill" which is great. I hardly ever leave an app and go back to the launcher to just sit and watch as it reloads. You have no idea how much better that makes it feel when I'm using my streak.
Thanks to whomever suggested trying this script in a previous thread here.

And will drastically change the behavior of your device.. And this has nothing to do with his problem, he's talking about some weird lag that happens after he boots, not a problem this script would "help".
I tried this script on my Nexus One, as I tend to do a lot of stuff at once, and it did nothing but annoy me. I never have launcher kill problems, so perhaps it's just not for me.. but I found that apps I could normally run simultaneously would be killed when I went back to them.
Example, running Car Home, Waze, and Gas Buddy on my trek to work. On top of the normal stuff running.. Normally Gas Buddy will be left in the background and I can bring it right back up, but after several different settings in this script it was always killed. Not to say this isn't a good thing for some people but it works better for me without it.

You don't have to root, it comes prerooted...
All you have to do is flash the Clockwork Mod recovery for Honeycomb which is 4.0.1.9 if I remember correctly (it has it's own thread) and then download the R6 HoneyStreak (R7 is buggy on mine that is why I suggest R6) and you flash it from Clockwork mod...
And the script is junk, it has been stated in several threads that the most it does is help the Launcher to an extent, the memory from the custom ROMs on the Streak 7 and Streak 5 conflicts completely with the script, all you get is a placebo affect once installed

Thanks for all the support. Now I just need a bad ass custom ROM to go on too of it.

Ubuntu Phone

I'm not sure if anyone's seen the news lately, but apparently Canonical is putting out a mobile version of its Ubuntu OS. I've seen the whitepapers so far and it looks promising (assuming it ever gets traction).
Assuming that the phone OS is open-source like its desktop counterpart, does anyone think we could possibly build ubuntu phone to work with kexec and safestrap 3?

Cant you download ububtu on the app market?

what you're referring to, is running ubuntu on top of the existing android system
what Canonical wants, is a phone that runs only ubuntu, no android base layer (*insert Canonical's claims about how java is too memory bloated, and mobile OSs should run C/C++)

Possibly, yes. Depends on how it is ubuntu is implemented fully though, however.
If it can easily can replace the android framework and go on top of our existing kernel, then yes.
If it requires specific kernel edits, possibly, depending on how much work is involved.
But with current kexec kernel issues, it probably would not be worth it until they get sorted out

From what I've read it's compatible with most Android kernels.

From what I understand, android was written over the Linux 2 kernel. You would think that there wouldn't be much of a difference, just adapt the drivers, but then again operating system implementation isn't my area of expertise.

Yes kexec is 3.0.31 i think

I don't see why it wouldn't work, having kexec we can bypass the locked bootloader situation, unless maybe it needs a gig of RAM, otherwise if a developer takes it up I don't see any reason why it wouldn't be able to come to our good ole 3.
And yes the current kexec kernel is 3.0.31 but yet again it can be updated or changed.

I wonder if Ubuntu won't loose most of it's usability on our tiny touchscreens... I used to use an HTC Universal with a few directly ported DOS-games. The tiny screen and the touchscreen instead of a mouse made them quite hard to control. And not even having a stylo will make it even harder to controll, I guess.

uh... well (from softpedia)
"Owners of unlocked Google Nexus 4 smartphones out there can now get a taste of a new Linux OS for their devices, as a Fedora 19 installer is now available for download for them.
The software enables them to easily install Fedora 19 for ARM on this Google phone, though it should be noted that this is not an official Fedora Linux project.
As phoronix notes, the installer comes from Rob Clark, who has been working on enriching the Freedreno Gallium3D graphics driver, and who used the Qualcomm A320 graphics in Nexus 4 for that.
The Fedora 19 installer that he wrote in the process is now available for download on GitHub as freedreno/nexus4-fedora, but might not receive support moving forth.
For enthusiasts, however, it might prove an interesting software to take for a spin on a Nexus 4, that’s for sure."
So, if you know Ubuntu touch preview - you know what this is

This is really interesting. I'm a long term Fedora user, and I've just bought a Nexus 4 with the intent of installing cyanmod on it. But for various reasons I would like to run a full Linux distro.
So my first question is this: Is there a phone app and a sms app available for any Linux distro? The closest thing I could find is gnokii, but it isn't for on the phone its self (at least that is my understanding). Would I have to write the phone app myself?
My second question is: Does it run well? (I mean Fedora on the Nexus 4) Or do need to find that out myself?
Thank you,
Christopher
PS. I've been searching the internet all day to try and answer these questions.

From what I gather from reading the README on github. This is NOT a ROM (not even close). This is absolutely not something to use instead of cyanogenmod, stock android, etc. And although I don't know positively (have not googled), I would guess no, there is not a phone or sms app for a desktop that is going to work. Not to mention how many other key components needed to make this a working android substitute.
What it is, is a kernel (a Fedora based kernel instead of an Android kernel). And you don't even flash the kernel... you load it and run it temporarily through adb. And then the installer will download and run an x11 display server (instead of the android surface_flinger server), and a Gnome desktop and other parts of Fedora.
It's not something that's ready for use as a phone OS. Far from it. It is just the beginnings of a start (though mad props are in order).
If you've tried the latest Ubuntu touch preview... and seen all of what's NOT ready in that project... then understand that this Fedora project is not even close to that stage of development yet.

Hi,
has anyone tried it recently?
It did not boot for me and got stuck at the "Google" logo.
ADB was working, but without wifi it is useless.

Computer for development

OK gonna go buy a computer this week for learning development. Everything seems to be on windows 8 now..... How will that work with developing and basic android stuff? Just need to figure out what I should be getting.

avoid windows 8 of you can it has dual boot issues. I would try to find a win7 box and partition half of it to Linux that way you have all the tools and programs available to you.

Windows 8 (or 7 or XP) -- not recommended for android development (at least if you want to get into building custom roms). About all you can do on any Windows OS is decompile the apks for smali editing, themeing, etc. Yeah, you can set up a Cygwin environment to compile, but you also need a really good PC to do that....4 core @ 3ghz and 8GB ram MINIMUM or it won't be worth doing....you'll be much better off doing it all on Linux.
Type, brand, and preinstalled OS don't matter. Android development needs a 64bit cpu (preferably dual core or better), 3GB ram+, a Linux OS based on Ubuntu 10.04 or 12.04...I gotta recommend 12.04 since 10.04 is no longer supported (LTS for it ended in May), and a hard drive with 50+GB....my partition with nothing but android development on it is 320GB and I use every bit of it (currently has 30GB left). 50GB is just enough to install an OS with enough space to sync and compile 1 rom....You'll need about 20GB per rom and 20GB of space free on the drive before you start the compile.
Just make sure you get a PC that allows you to install another OS (some OEM Win8 PC's are bios locked to only install/boot Win8.....)

Depending on your bios/motherboard you can't dual boot with Win8. Sucks, but that's how it is. Guess MS feels threatened by *nix and Boot Camp OSX

Ubuntu is a great OS alternative to windows which is constantly updated with great features.

The first one, but you're really gonna want something faster...You're looking at 3\4+ hours compile time for a single rom. Quad Core @2.4 Takes 2~2.5 hours, Dual Core @2.4 Takes 3~5 Hours, both with 3GB ram.
Do you already have a PC? If so, for ~350 you can get a good motherboard and an 8 core amd....another bill for some ram and you'll be set for the next 10 years other than graphics. Using Brand New Prices. I don't know your budget is, but that's what I would do provided I had a decent budget to work with.
