Android :: Reading And Writing To File In Internal Storage

Jun 27, 2010

I'm writing a simple budget app for myself, and I'm having trouble figuring out how to write to internal storage. I don't seem to be writing to the file properly and I can't find any more in depth examples than the Data Storage article on developer.android.com. Basically, I'm trying to write a test float to the MyBalance file, then read it into balance. In my actual code I use try/catch statements around the file in/out operations but I skipped them to make the code more readable.

float test = 55; float balance; byte[] buffer = null;
FileOutputStream fos = openFileOutput( "MyBalance", Context.MODE_PRIVATE );
fos.write(Float.floatToRawIntBits(balance));
fis.read(buffer); //null pointer
ByteBuffer b = ByteBuffer.wrap(buffer);
balance=b.getFloat();

That's the gist of it, anyone see what I'm doing wrong? I went ahead and converted to/from String but I still don't think the file is being created. I have an if statement that reads from it if it exists in onResume() and it isn't being run. Lemme post some of my code. Here's how I'm writing the file, (setbal is an EditText and balanceview is a TextView):

balance = Float.valueOf(setbal.getText().toString());
balanceview.setText(setbal.getText());
balstring = String.valueOf(balance);
for (int i = 0; i < balstring.length(); ++i)
try { fos.write((byte)balstring.charAt(i));
} catch (IOException e) { e.printStackTrace();
}
I check if the file exists in onResume() like so:
File file = new File("data/data/com.v1nsai.mibudget/balance.txt");
Is that where an internal file for that context would be stored?

Writing Text To Internal Storage

Mar 12, 2014

Im trying to write a string to a text file on the phone internal storage

i use the following code

protected void writefile() {
String FILENAME = "filedemo.txt";

Android :: Writing Files To SD Card Failing?

Feb 7, 2009

I'm writing an podcast playing application. The application has pre- defined feeds but I want to cache the image of the feed for 30 days. However, on the initial creation of the podcast I am downloading the image, and trying to save it to the SD card using the code below:

CODE:............................

However, it keeps failing on the line k.createNewFile(); with the error: WARN/System.err(10727): java.io.IOException: Parent of file is not a directory: /sdcard/twitcast/1.jpg

I've checked and I have write permission and the SD card is mounted, and I have android.permission.MOUNT_UNMOUNT_FILESYSTEMS included in my manifest. why this keeps failing?

General :: Formatted Internal SD Card Through CWM And Now SD Card Not Be Detected

Mar 23, 2013

I formatted the internal SD card through CWM and now the card cannot be recognized by Win7 and it's stated as a linux file-CD Gadget USB Device, and the drives are greyed out. How do I revert the SD Card back to FAT32 format?

I'm also unable to mount it as USB storage in CWM recovery giving an error of cannot write to lumfile (no such file and directory). However, I'm able to still format the sdcard in cwm but it does not solve the problem.

Android :: Writing To SD Card - Deleting Files On It - Number Of Files Relevant

Mar 19, 2009

I wrote an app that downloads web sites and all their assets (images/stylesheets) to "disk" and therefore stores lots of small files on the SD card.

Sometimes it fails to delete large amounts of files and afterward the file system is r/o. To analyze that behavior I tried to do the removal of the files by hand and then go from there. But that already failed.

localhost:~ mkamp$ adb -d shell mount [.. some mounts ..] /dev/block/mmcblk0p1 /sdcard vfat rw,dirsync,nosuid,nodev,noexec,uid=1000,gid=1000,fmask=0711,dmask=0700,code­page=cp437,iocharset=iso8859-1,utf8 0 0 --> R/W

Last login: Wed Mar 18 19:41:49 on ttys005 localhost:~ mkamp$ adb -d shell rm /sdcard/newsrob/a* [.. minutes of silent deletes ..] rm failed for /sdcard/newsrob/a2aade03616c28b30_113.png, Read-only file system localhost:~ mkamp$

localhost:~ mkamp$ adb -d shell mount [.. some mounts ..] /dev/block/mmcblk0p1 /sdcard vfat ro,dirsync,nosuid,nodev,noexec,uid=1000,gid=1000,fmask=0711,dmask=0700,code­page=cp437,iocharset=iso8859-1,utf8 0 0 --> R/O now

The log contained nothing but the usual gc output and random WiFi status changed mumbo jumbo.

Anybody else seeing this behavior?

There were 6.500 files in that directory. Might that be the problem? I don't access the files with queries, I always have the exact name.

Android :: All Devices Have An Internal SD Card ?

Nov 7, 2010

On the first run of my app, I am downloading a pretty big file to /sdcard/

I already know this can fail if the internal SD card of the user's phone is full or not mounted (e.g. if the phone is connected to a PC as a mass storage device, or has not been properly disconnected from a PC).

But are there any android devices with NO INTERNAL SD CARD ? (on which my app would definitely be unusable)

HTC EVO 4G :: Limited Internal Storage And Bigger SD Card

Jun 17, 2010

My internal storage is currently 337 MB. I was planning on buying a bigger SD card, either 16GB or 32GB. I'm very new to everything with Androids and have never been big with computers. I read that if I want a lot of applications and everything that I would have to root the phone because the internal storage is so limited and then move everything to the SD card. I tried rooting the phone, it didn't work (I didn't mess up anything with the phone, probably just missed a step), but considering I still know so little about all this I decided it would be better to wait with rooting. Will I be fine with not rooting my phone and picking up a bigger SD card or will my phone run very slow once I start installing a lot of stuff?

General :: Exchange Internal USB Storage With SD Card

Jun 5, 2013

Bricked my Maxell Maxtab C8 while trying to exchange the Internal USB storage with the SD Card. The only thing that happens when it boots is that the Android Boot logo comes up and stays there forever. I have managed to get it in some kind of recovery mode (image of cute green little android laying on it's back with with a red triangle), have also managed to install Android SDK manager and issued the command "adb devices" in shell - reporting "{serialnumber} recovery".

I need firmware to put on the device, where I can find that? Does not need to be original (4.1.1), I'm satisfied if I get it to work again.

As far as I know it's some kind of MID tabled branded Maxell, at least it said that in the settings while it still worked, and also Windows claimed that.

General :: Emulated Internal Storage As SD Card?

Apr 16, 2014

Yesterday I received my Huawei Honor 3C and I've installed MIUI ASAP instead of Emotion UI. Everything's great but I have a problem with double SD Card, I mean: I have my own external card and the phone got his own by emulating it's internal storage as SD Card (it's a symlink to /storage/emulated/0 and it's the same as /storage/emulated/legacy, so this fake sd is eating up my storage, there are also other symlinks in /storage/, /mnt/ and even in root folder there is a symlink sdcard->/storage/emulated/legacy). Phone and apps are correctly seeing external card as SD Card but in reality the internal storage is being used for everything.Because of this I have only about 5GB available instead of 64GB

Is there any way to terminate the emulation or changing it's target to sdcard2 so that I could use my card correctly? I've tried few things but nothing works. Symlinks are being recreated during boot so editing or deleting them does not work. Editing vold.fstab does nothing because ext is being mounted after boot while the emulation stars while in it - I guess that a proped ini script could do the work.

General :: How To Recover Data From Internal SD Card

Mar 6, 2013

I recently went about updating my tablet, and in the back of my mind I was under the impression that TWRP would backup the internal sdcard's files during the normal backup, so I thought nothing of wiping the internal sdcard. Whoops. It, of course, didn't, and now I find myself with a whole slew of stuff gone. Not much else was written to the internal sdcard (which is on an ext4 filesystem), so I suspect that a good bit of my stuff can still be sitting there in the data graveyard.

Since I'm on Linux and can't mount the sdcard directly (since for some odd reason Linux has issues with MTP), all I've been able to do was this:

I booted the tablet into recovery mode and opened up adb, and ran the following command through the adb shell:

Code:

~ # dd if=/dev/block/mmcblk0p8 of=/dev/block/mmcblk1p1

Where mmcblk0p8 is the internal sdcard with the lost data, and mmcblk1p1 is an external sdcard. I thought that by running that command, I could create a carbon copy of each and every little thing on the old sdcard, write it onto something my computer could read, and then go through the normal recovery process. In this case I planned to use a Linux tool called "extundelete."

Here's where I get stuck. The sdcard appeared to have cloned correctly, given that the entire thing is now filled up and reads as an ext4 filesystem on gparted (when it was previously fat32), but now I can't mount it. And if I can't mount it, I can't restore anything. Here's what I get when I try to mount it:

Code:

Error mounting /dev/sdb at /media/user/57f8f4bc-abf4-655f-bf67-946fc0f9f25b: Command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdb" "/media/user/57f8f4bc-abf4-655f-bf67-946fc0f9f25b"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb,

missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so

So to sum it up, I accidentally wiped my tablet's internal sdcard using TWRP 2.3.3.0, and now I want to recover what was lost during the wipe. Not that it matters, my tablet is a Transformer Infinity.
