I need to write a fairly simple .csv file to the device's sdcard (so it can then be emailed via Intent). The below code does not write the file.
CODE:...........
More code here:
I flush and close out_stream. I can even seem to be able to read from the file on the device (printing above output, using fileinputstream, to an edittext.
How can I get to this file on the sdcard?
I found out that you can use something like this to create a file:
CODE:............
When running the above code I get an IllegalArgumentException stating:
CODE:......
And Im guessing the "/" is not appreciated. I wanted the "/" since I need to write the file to the root directory of the device, as stated in the API in trying to follow:
CODE:.........
Question is: how do I place a file in the root-directory? I have been looking around for an answer, but havent found one yet.
I have tried a lot of custom Roms. I'm on Neat ROM Lite now. Not sure which ROM changed my file access permission settings to cause this problem but I'm not able to delete any files from my external memory card. I was able to delete when I was on stock rom. The other problem is for a few apps I get an error message which says can't install on usb/sd card. I have posted this in another thread some time back but got no response.
This is what my file permission looks like.
I am able to delete when my fone is connected to PC via USB. So I don't think it has anything to do with a faulty sd card.
When making an image I accidentally had Clockworkmod image be saved to the device itself instead of being saved to the external SD card.
I am able to browse to it using Root Explorer and select to Copy it, but how do I PASTE it onto the external SD card when Root Explorer only accesses the device directory and not the external SD card?
Quick 2nd question: I know on some previous devices such as the Galaxy S 4G you were *not* supposed to run Clockworkmod after booting in and from the Apps Drawer, instead you were only supposed to run directly from the startup screen before booting in. Is it OK to actually start the Clockwork Backup/Restore process from the Apps Drawer of the Galaxy S4 and let it reboot and do its thing or is it only supposed to be run BEFORE booting in?
Specs: ainol novo elf 7 tablet A10 processor. it has android market. (google play )
ICS 4.0.3, kernel version 3.0
it came with some chinese apps etc (identifying which rom it was, i believe it was factory rom).I ask torrents to download in my sd card, it says error , permission denied .
EXT CARD SIZE: 2 gig only. manufactuer says tab supports upto 32 *gig card...card wroks fine on my nokia x2-00 phone
Investigation:
1)i tried creating directory in using File manager...it did, ...it didnt show option of deleting / pasteing something.
so i used es file explorer........when I asked it to delete that empty directory i created , it said error permission denied.
2)i try to paste something, it fails.
3)i try to delete something it fail.
So, FORMATTED the memory card (via pc...connected it as usb, formatted, ejected), TRY TO PASTE SOMETHING via tablet, it fails
how can you tell where an app is being downloaded to? is everything set to download to the sd card?if not what is set to download to the phone memory? i'm guessing phone back ups and settings?
View 3 Replies View RelatedI have been having this problem since i updated to froyo JP2 package my external micro SD card when mounted to computer and i try to copy over the files it says it is write protected but there is no key to slide, as everybody knows micro sd cards donot have that feature by design. this is the best part when the same card no changes i put in to a cardreader hooked up to my laptop works perfectly fine. it was working fine before i flashed the JP2 firmware. what am i doing wrong i even formated the card in the phone itself but still no luck. My hunch is this when i flashed with new firmware i never took out the sd card and the sim card is that any reason, i know i can just flash it again but i already arranged everything nice on my galaxy so was wondering if it is then i will go ahead.

I currently connect to it via a WM 6.5 app running on my Palm Treo 750. I would like to port my WM 6.5 app to an Android phone. (I don't have a specific Android phone in mind, I would like it to be as generic as possible).Replicating the GUI is not that difficult, but I am having trouble getting started on the USB communication. I'd appreciate it if someone could point me towards an example, or the appropriate tutorial.
View 1 Replies View RelatedI am using a mt6582m device with kitkat 4.4.2 with supersu. I can use root to write to system, data and cache using es file explorer, can also read and write to any sd card, but apps like titanium backup, online android backup, ram expander can't read/write to sd card.
Eg.1: ti backup read backups, can do all operation except backup and restore.
I had read a lot, changing backup path didn't worked nor any odex file is there. Using v6.1.5.6.
Eg. 2: ram expander can create swap file on sd but can read it saying 'not found'. Swap can be used with cache partition.
Eg. 3: online nandroid backup says pat not vaild.
I had tried, sd fix app, manually editing platform.xml, xposed module to 'handel external storage', change permissions using es file explorer, editing ramdisk.
There is storage/sdcard0 and 1
Also mnt/sdcard and mnt/sdcard2 (symlinked)
Also mnt/media_rw/sdcard0 and 1 (not readable even in es file explorer)
I was wondering if anybody happens to know what is the max external memory can be put into the Incredible?

I have a tablet with internal SD (nand one) and an external SD.
Now I can read contents in internal SD but can't write it. I checked up with root explorer, finding the file sysytem is "read only". After toggling it to R/W, the storage can be written by root explorer but still can't by other apps.
================ EDIT ================
p.s. When connected to PC as massive storage device, it can be read and written.
Few months ago i installed CM9 on my Galaxy Tab 7+. Everything worked fine to begin with, but after a while i was unable to delete stuff off my microsd card. I wound up buying a new card, copied the music and tv off the old card and installed it. Same problem. Now i have 2 microsd cards that I'm unable to write to at all. I can't write anything to them, can't delete anything off them and can't format them. I've tried using them both in my phone and on 3different Windows PCs with the same results. I have tried the SD card write fix referenced in the Galaxy Tab Plus development section and that didn't fix anything. The problem seems to be with the cards themselves, not the tablet (and phone and multiple pcs).
View 1 Replies View RelatedI've started seeing some apps that offer to read/write data to the internal phone memory (like Super KO Boxing 2, which offers to save a whopping 52MB to the phone memory). I suppose this is because newer Android devices have a lot of internal storage, as opposed to my devices, which have very little. I would like to support internal storage in my app as well.
But it's a bit difficult to implement a solution to something that I don't really know how it works. For example, do these newer devices allow users to upload files to the internal memory, like it's possible to do with the SD card? Can someone explain internal storage from an user perspective and recommend strategies for supporting read/write operations both for internal and external memory (ie: letting the user choose which memory to use at startup, like the Super KO Boxing 2 app)?
my phone is HTC Sensation XL CM10.1. when i switch on my phone, it stuck on CyanogenMod, i restart my phone so many time, so what i did was i format my phone from bootloader. I'm having problem with my EXTERNAL MEMORY. this is not SD CARD since HTC Sensation Xl DOES NOT have memory card slot. it's HTC Sensation XL 16GB.
my problem is everytime i enter camera and gallery, it says "No external storage available" then my whatsapp also cannot download images and videos. then when i go to storage, it shows only internal memory available, it does not shows the External one, it seems like the external memory is not inserted.
i already restart my phone so many times . then i go to recovery, then i tried to mount sd card, but it said "cant mount Sd card" then i tried to format sd card but failed since the sd card cannot be mounted.
then i try to connect my phone through USB to my computer, but i cant even read the sd card, there's no notification that my phone is connected through USB. but its connected already.
if i cant connect through USB, then how can i solve this problem? how can i flash a new rom? how to downgrade my phone since i have read from most of the forums that the only way to solve is downgrade the phone to stock. but i cant even connect it through USB to put the rom.
My memory card is always unexpectlly removed when my device is idle, so I have to wait my gallery recreate thumbnail if I want to use it

In my android app, is there any way to get the total amount of memory my application is taking up, in the code. I'm using lots of large bitmaps, so it must include external allocations as well. I must, however, be able to get the number in the code, so that I can dynamically adjust to fit the budget I have.
I also need a way to get the total amount I have available (16Mb or 24Mb) as well.
After googling and searching alot, i didnt find my answer. So install apps on SD Card or Internal memory ?

When booting, the screen stays on the welcome logo, and stay there forever, and adb could connect to linux shell on the phone. I can see all file on the phone, and I can save files after "mount -o remount / /", but after reboot, the file is gone.
If I use fastboot to flash a recovery into my phone, by follow command:
