The robustness of the file system is very critical for a mobile device. YAFFS2 is a file system that was designed specifically for NAND flash, which is supposed to be more robust than EXT3 file system in terms of NAND flash. I wonder if there is YAFF2 support in Android platform? or there is an alternative other than EXT3?

I created img.yaffs2 using mkyaffs2image and then mounted it into Ubuntu MTD NAND flash simulator. so if I use 'cat /proc/filesystems' I can see yaffs and yaffs2 and by 'cat /proc/mtd' I can see /dev/mtd0에 Nand simulator partition 0. (block size is 0x4000).................
View 4 Replies View RelatedI have some images that I exracted using dump_image. I'm trying to restore them with the MTK Flash Tool. The ones that go on FAT partitions seem to flash fine but the ones that go on yaffs2 partitions don't work.
I think I need a way of converting the images I extracted to yaffs2 images.
Is there a cogent reason why the SD card cannot be partitioned without a FAT32 filesystem? From all the benchmarks I've ever seen, EXT4 kills FAT32. However, when I tried using an SD card partitioned with only an EXT4 partition, vold (the volume management daemon) wasn't happy at all. can manually mount the volume from the shell, but that does no good as far as android recognizing that the partition has been mounted.I'd be willing to hack up the vold source code if it would be useful, but I just want to know if anyone has any thoughts or experience on the issue.
View 7 Replies View Relatedi successfully got into adb in recovery mode fairly easily on my ubuntu 10.4 laptop using the following method- this should also work for a linux live boot from a usb flash drive
in one terminal tail and follow log messages
~$ tail -f /var/log/messages
In another terminal run the loop
Then
1. plugin usb and keep it plugged in
2. remove battery, eject sd card.
3. put battery in
4. press vol- and power
5. after around 6 seconds, your terminal with the log will show something like "new high speed USB..."
6. press vol- to select recovery
7. press the power button
8. IMPORTANT- as soon as you see a new log entry (something like "USB disconnect"), pop in the sd card
check your loop terminal for adb. if it doesn't work, repeat at step 2
I would like to know the best way to copy a file in the filesystem? (android java function )(sdcard/video/test.3gp -----> sdcard/video_bis/test2.3gp)Is there an example somewhere?

View 2 Replies View RelatedEverytime I start my phone up it says the SD card is or has unsupported filesystem. When you click on it.. it asks to format... you click "format" and then the phone just freezes. If I receive a picture in a txt and I click on it, the phone freezes. When I plug my phone into the computer through the USB cable, mount, and try to format it through the computer it says windows is unable to complete the format. I've reset the phone to factory reset also, no luck.

I have tried to implement my custom Content Provider, but method openFile returns ParcelFileDescriptor that points into filesystem (or socket). My pictures are in filesystem, but in encrypted form.
I have tried also URL.setURLStreamHandlerFactory, but in android java it is useless (because custom streamHandler can be register in jvm that is not allowed). I also try html code "img src="data:image.gif;base64,R0lGODlhiAAkAMQAANOOk...", but in embedded chrome it's not working.
Is it possible to access the filesystem of an sdcard image through something like Windows Explorer?
i.e. mount the sdcard as a drive or web folder or something. I have some xml files stored on my sdcard image which I frequently want to edit.
Ideally I would like to be able to edit these files directly using my fave xml editor (either through the filesystem or webdav).But is this possible?
If not, is the only alternative to pull the xml file from the sdcard to the dev machine filesystem, edit and the push it back?
I am new on android and building an application which uses webservice to collect user information in XML. I also get path for a small jpeg picture of each user. (Currently there are about 200 users) I am parsing the XML and storing the information in SQLiteDatabase. Pictures are stored as blob and able to retrieve them.
I display names of users on listview with images as well. But is this a good solution for storing pictures in SQLite Database ? or should consider storing it in file system ? Which is suitable in terms of performance , as well as memory and any other pro and cons on Android.
Also like to know which is best performing XML parser for Android ?
My purpose is only to parse xml files which I get through web services and sort out the data to store in storage. And lastly my memory goes off easily when I load all images to display in list view after making thumbnails of each (which is obvious).
Was wondering is there any library/framework/app available which dynamically loads images as and when required (when that list item is on display) something like Gallery program ?
I know android is based on linux, does this mean it can run any and all linux applications? If so has anyone tried to run anything like wine? I also noticed that by default you cant run apps directly from sd card, but i saw a modification on a site that lets you change it so you can, so technically speaking is there any limit on the size of sd the G1 can handle?

View 1 Replies View RelatedIm totally new to the smartphone/android topic and very happy that i managed to partition/debrand/root my Desire and flashed LeDroids Rom on it! ^^ ( im a windows XP user )But i have some questions about my partition and filesystem: I have a 4 GB SDCARD and a 512MB Partition on it for the apps. So i figured out there is a mnt folder that seems to be like an exact copy of my SDCARD folder.
How do i know what my partition is ?
And how do i know how much space is left there for Apps?
When i plug in my Phone via micro usb and browse my SD card i dont see a MNT folder. Does that mean the MNT folder is the main partition (3,5bg?) ? Because when i download a youtube video via jetVD (i was prompted to use a download folder on my SDCARD) it saves the videos under: mntsdcardmovies (also my player shows the path to that directory)but the movie files are also available under: sdcardmovies
Could somebody explain that. btw: i use the app SUFBS to browse the SDCARD on my Desire.
Is it possible to copy a file located on the sdcard to a package's internal filesytem located at /data/data/packagename/files/ folder?
View 3 Replies View RelatedI have a couple basic questions I'm hoping I can get answered before I start messing around with different ROMs/Radios/Kernels. Before I rooted, when I felt like things were getting cluttered or had an OCD attack, I would do a factory reset. How does that work?
What "source" files are used? Is the emmc directory the only directory not "cleaned" in a factory reset? Keep in mind I'm used to my workstation/laptop experience where I would format, then install a clean version of the OS from a CD/DVD and then I would install 3rd party apps and move my data back?
Any analogies would help my simple mind! One day I did a factory reset, the decided to root. Everything went perfect. I moved some bloatware to an apps.disabled directory, then did all my customizing again. Now I want to play with different ROMs. I do however want to hedge my bets in case I ever want to go back to where I am today. I've done a clockworkmod backup.
Does that essentially copy all the phone storage (except SD Card data) over to the SD Card? If not, what is left behind. Will a clockworkmod wipe erase ALL of the on board phone storage (except the SD Card data)?
I'm a big fan of just having direct access to my devices (i.e., no sync, no "management" front end). So this isn't about local access from the device (using MyFiles or Astro), but from a PC in the same location (so not like 3G remote). So far I've explored these options: USB Connect phone, mount from notification menu, and there you go. Bluetooth Pair phone, use "send file" from PC BT app (running in system tray).
Files drop into a 'bluetooth' directory, ready to move/use. Android Web OS Very beta-esque right now, but runs as a service on the phone, then you can access the filesystem (and SMS, eventually other functions). You can copy up to the phone or download (basically via a simple web mechanism). Use across Another service on the phone, a basic FTP server accessible across WiFi.
Works pretty good so far, I created a 'network location' in Windows, then a shortcut on my desktop into my MP3 directory on /sd. So I just open that folder, copy over MP3s. Doesn't matter where the phone is currently sitting or connected. For the services type options, I'm going to check out something like Locale or Tasker, when I can trigger the service to fire up based on a rule (a specific WiFi network trigger would be outstanding).
I received a Text message sent from an E-Mail and I was wondering if it was possible to find the individual file on the filesystem holding the metadata for the E-Mail.
If so, would I have to root the phone? And where would that file be located?
I'm a techie, so no need to warn me that I could hurt my phone or files - I'm only looking to READ, not WRITE, and I'd be making a copy of that file beforehand anyways and porting it to a PC in order to check it with whatever program is necessary to decrypt (Probably only need a hex editor.)

View 1 Replies View RelatedAndroid and Linux kernels started re-merging at version 3.3. People said that a short way down the road, android apps would be able to run natively in linux. the kernel is now version 3.6 and I've heard nothing more about running android apps in linux. people on these and other forums put a lot of great work into getting linux running on android devices. now with windows 8 coming out, the market will be full of both ARM and x86 based touch devices of all sizes and shapes. I for one would love to be able to boot up ubuntu on one of these devices, and use either traditional linux apps or android touch apps as my mood and situation dictate. so- any new word on when we will be able to run android apps in linux?
