[Q] app2sd questions - Android Software/Hacking General [Developers Only]

Hi,
I did a quick search of these forums for some answers to my questions, but I didn't find anything initially so apologies if I missed something...
I currently use a Samsung Galaxy S running on stock firmware, recently updated via Samsung Kies to 2.2.1 and subsequently rooted using v1.7 of the SuperOneClick tool downloaded from this forum. I've come across a website called samfirmware.com which has the Gingerbread incarnation of the Android firmware available for download for my handset (not sure how stable this is though , any thoughts?). I'm OK with flashing new firmware since I've already done this recently on a Samsung Galaxy Europa, so I have some knowledge on this topic.
I would like to test this on my Galaxy S with the aforementioned Gingerbread firmware, but I would like to be able to save some of my apps and their data beforehand. I know that the Froyo incarnation of Android has the so-called app2sd function, but I have a couple of questions about this implementation I would like to ask before I go ahead:
- When you save an app onto the SD card using the built-in function of Froyo does this also save any data that the app has stored since installation (e.g. bookmarks created with the Dolphin HD web browser, levels of Angry Birds completed)? If not how could I go about doing this?
- Hypothetically if I were to save Angry Birds (or any app for that matter) onto my SD card and re-flash the firmware on my Galaxy S, can I then pull Angry Birds (or whichever app I saved) from the SD card back onto the Galaxy S along with all the saved progress/data?
- Are there any other potential issues with this process I should know about, or anything else that I should use or read that might help?
Any help would be appreciated. Thanks.
Regards,
Jon.

as far as i know, what you want to do is not possible with froyo apps2sd.
but since your device is rooted, you can use TitaniumBackup (can be found in market)

Few Questions...Plz Help

Hi I'm new here and have a few questions. I downloaded some apps off the web but when they are updated I cannot update them using the market. Is there any way for me to update them or add them to the "My Downloads" list in the market? If I root my phone, but do not install a custom rom will I still get ota updates, be able to install market apps, and so on?
Details:
Phone: Nexus One (T-Mobile Version)
Android Version: 2.2 FroYo FRF50 (love it)
If you guys need baseband and kernel information let me know. Also, what it different in stock froyo vs cyanmod vs any other rom? Sorry if this is in the wrong place to post this and the length.
Hi there, as of right now all that I can point you towards for you apps would be an app called apktor that can be found in the market the rest you will have to figure out on your own. Or you could also just redownload these apps through the market...
From what I have read besically when you root your phone you give up any chance to be able to OTA update. BTW I have a Telus Milestone so I am not sure about the phone you have because it might be different but I think it would be a global rule of Rooting= No OTA... Although while being rooted you can install apps from the market.
About the custom roms you will have to do some reading untill the Milestone's boot gets cracked I won't have a chance to play around with any roms, I guess best advice would be read read read and read some more. And after you have done all that reading, choose a couple of roms that interest you try each one for atleast a day and find the one that you like. If there was a best rom, there wouldn't be such a wide variety of them...
~PsyCl0ne
Nope, even if your phone has root you can still update apps via the market. I know because I updated my apps via this way. 2 Rules apply though.
1) The apps that you downloaded off the web are freeware and are also on the market.
2) The apps that you downloaded off the web AREN'T warez. (I'd suspect that's what you're trying to do, but do correct me if i'm wrong)
It is highly unlikely that in following these 2 simple rules you still can't update via market.

[Q] Switch between OS on HD2 / uninstalling froyo 2.2 from hd2

Hi,
I am new to this forum. sorry if i repeat the question but I tried looking all over and I could not find any answer for my question, which is as follows...
1. If I experiment froyo 2.2 on my HTC HD2, how do i swith to and forth between Android (froyo 2.2) OS and Windows Mobile OS. Is it easy to do so?
2. If I don't like froyo running on my HTC HD2 because of technical difficulty, how do I switch back to original HD2 operating system, like I never tried Froyo installation (in other words - how do i completely uninstall froyo from the device)?
Sorry if I repeated the questions, but, again as I said, I could not found it on the forum.
Thanks
It actually just runs from the memory card so basically you just have to restart the phone, let it load windows mobile then delete the android mobile on the sd card. Below is the section for android roms basically just download and unzip to your sd card in an "Android" folder there might be more to it, but there is a thread with instructions too.
http://forum.xda-developers.com/forumdisplay.php?f=735
I had the same question and searching for the answer has led me to your post. I understand that the Froyo system files reside on the SD card but I'd imagine some sort of startup file on the phone itself has to be modified to point the boot sequence to the SD card. Is that correct and if so, what file(s) is modified on the phone? More specifically, I'm researching the Froyo install and want to do it without any custom ROMs, just stock, but I'd like to make sure I can remove all traces should I need to send it in for warranty purposes.
abc12121, did you get any more information on this that you could share? Can anybody else explain what, if anything, is modified on the phone to point to the Froyo install on the SD card? Or how the boot process works?
Thanks!
Superram Froyo not loading
I recently installed Superram Froyo from Darkstone on my HD2. It worked absolutely great for a day. Then all of a sudden, it stopped loading. I tried to repeat the process of booting but all it does is shows the green HTC logo and then the screen goes dark...and stay that way. Any advice or help is appreciated since I was begining to really enjoy it.

[Q] Converting Galaxy i5801 to Offline wikireader

Galaxy 3 (i5801) is my first android taste, and I love the phone even after buying Galaxy S and Galaxy Nexus I still kept the phone with me.
I was thinking of using it as an offline wiki reader . I zeroed to use kiwix as offline wikireader app but it requires above Gingerbread rom.
So can anybody suggest
1. any 4+ android rom (i.e ICS or Jellybean) even if camera or blutooth not working
2. It should have support for any file system which supports file size more than 10 GB (like ext2, ext3, ext4 or ntfs, not fat 16/32)
Thanks in advance.....

Thanks gogozx,
I tried to flash your rom on my Galaxy 3 (i5801), but while booting all I can see is sometimes nexus screen after that a white screen.
Here is what I did,
Since yours is a tar file so I used ODIN single file to flash while my phone is in download mode.
When ODIN triggered reboot my phone went in to CWM from where I factory resetted, cleaned both Dalvik as well as cache.
Then rebooted my phone, initially I saw Nexus screen then all of sudden my phone screen become white. After a while again I saw Nexus screen again white screen.... This continued.....
DId I do any thing wrong ?
That sounds like a boot animation issue. But did the phone finally boot into homescreen?
My bad I waited for a while and thought its a boot loop, later I flashed again and after a while I did see the home screen.
Everything about this rom is nice, but I failed at the basic step, as there is neither market place nor file explorer so installing any app is near impossible
I tried most of the options mentioned in the Killer G3 thread but none seemed working for me (like flashing gapps or installing file explorer from the browser etc).
Any suggestions..... ( I am almost near to completion of my project > Insalled jellybean rom > Have to install Kiwix app (pending))

Hurrahhhhh I had finished .....
1. First of all I had installed Killer G3 rom (One problem though is installing google playstore is little difficult in this rom, without which you can't install any app as file browser is also missing, but with the help of rom developer I did managed to work)
Or you can install AOKP (easy option)
2. Then installed Kiwix (along with that you need to download wikipedia in zim format which are available at Kiwix.org)
3. Since zim files of full text are at least 10GB in order to keep those files on your micro sd card (FAT32), you need to split the zim files in to 2GB parts (procedure in mentioned in FAQ section of KIWIX)
4. Thats it, my old phone became an offline wikipedia reader
Thanks to rubensollie (AOKP), gogozx (Killer G3 Rom)
Easy solution for those who have older version of Android
1. Install Aard dictionary (available in google playstore and can be installed on old versions of andorid)
2. Download the offline wikipedia files from the dictionaries section in Aard
Thats it you are with an offline wikireader. The second method is best as it has been updated recently, so its wikipedia dictionaries are much more updated.

[Q] Should I stick with...? (More info inside the thread)

Hey, newbie here. I would like to know if I should stick with my Samsung Galaxy Ace 2 Gingerbread 2.3.6 or should I upgrade to Jellybean? I got hard time actually... I upgraded then downgraded my Ace 2 many times to be honest. I just kept breaking my phone. Just a small break and I know only 1 solution. By upgrading it then downgrading back. (What? Don't be mad at me for that.. I'm a newbie. I don't know what to do.) Well, all I want is to play games :3. Is playing games on Ace 2 Jellybean good? (Well, on my last upgrades, it sucks. It lags.) Is there like any way to make gaming better in that phone? Also, is there any way to use my SD Card/Micro SD Card? Ace 2 only has 1.10gb USB Storage and I don't like that. I want to use my 16gb SD Card/Micro SD Card to be my default downloading and installing storage so I could play higher size games. I heard something about ROM's but I don't know anything about it... what I know is how to upgrade/downgrade my device and how to root my device... I don't know anything more other than that. If any of you could help me, it would be very appreciated
So... after the long no replies, I found this thing out...
http://forum.xda-developers.com/showthread.php?t=2495541
Is this good...? Would it do great for games than the Samsung release one?
hello
if i were you if you can update your gingerbread to jellybean i will do because you can play more games and also more extra feature on your android device...
>to have a safe upgrading you can search your device here and find how to get a jellybean os version of it.
>>then after that find a perfect rom for gamers like you but make sure it is well tested, stable and safe to your device .
>>>or have apps to lessen the lag...
you can use your sd card as a storage of your game save files..
by using link2sd and folldermount app..
just before you do anything to your device ALWAYS do a nandroid backup for safety.
and make sure you have enough knowledge.. always use the search buttons!

im just tryin' to help, so i hope it works:good:

I need a little bit of info.

So ever since I heard about rooting Android devices I innediately done some research on how to do it and I did it. I have had this root on my Samsung Grand Duos for a while now and all I have done is have a few apps (Lucky patcher, Freedom, and Exposed with 1 plugin or w.e) and I am pretty sure I can do far more than just that, so that's why I made this thread. I have a few questions I would like to be answered if you know anything about it.
1) What are customs ROMs and what can I use them for?
2) I am a developer and I have helped make some apps for both iOS and Android, would my root be useful in any way?
3) When I tried to upgrade my version of Android it told me that my version was modified, is there any way I can upgrade to the latest version? And would it remove my root?
4) Is root only compitable with specific versions? Like when a new version comes out, can you root it immediately or do you have to wait for something to do the root process again?
5)My device storage is pretty small and it makes it a pain in the ass to install apps, is there any way that I can edit that? (I am probably going crazy with this. lol)
Thank you.
Bump, would still like some help.
1) 3) 4) a custom Rom is a modified android, mostly based on clean aosp. The example CyanogenMod: you can choose between different Android versions. And with a custom ROM you have great efforts such like theming engine, overclocking or other nice features that are really useful but uncommon in stock ROMs. So I recommended anyone who decides to root his phone to flash a custom ROM neither a stock root
A lot of the info is available on XDA forums, tutorials, and on Google so I suggest you start doing some research as it will help you understand wholly much better...
1 - Custom roms are what nico331999 explained. Modified android firmware made for each specific phone model by developers. Its their take on android and most come with many extra features, themes, launchers, based on different android versions, etc. Cyanogenmod is one the popular ones, but there are a lot more. You would have to search the forums for your specific phone. In order to install a custom rom, root is not enough there are other things you would have to do which you will again need to find out for your phone. Generally speaking you have to unlock the bootloader, install a custom recovery, then flash a custom rom along with gapps.
2 - If you develop apps which utilise root access you can allow them sort of 'admin' access to everything on your phone, so you can perform any task with the app which requires such access. One example is replacing system level apps.
3- If you install a custom rom it will have its own version of Android, usually they are updated versions. You can download the FTF file for the most updated firmware version for your phone and then flash it on your phone. You'll be able to search online for instructions and downloads. A new firmware will remove your root and you will need to root it again. You can search for pre rooted firmwares though to avoid that step.
4 - Yes, you have to search for a rooting method for each firmware version of each phone. Developers (great guys) figure out these methods and post them online for the world!
5 - If your device has SD card support you can install many apps on the SD card to save some space using apps such as Apps2SD or Links2SD. You can move all your media to your SD card. If your device doesn't support SD cards I suggest you move as much data as possible to your computer, and maybe use cloud storage at the same time. Also, since you have rooted your phone, you can use an app like Titanium to uninstall bloatware (unused apps which you cannot usually uninstall).
All of this stuff seems like a handful when you first get into it, but you need to get out there and start researching these topics for it to all fall together in place...
I have to add something with apps to SD: some manufacturers (especially Samsung) have a very weird external storage handling (called emulated storage) which doesn't allow you to move your whole apks. It only saves user data.
