View 2 Replies View RelatedI need to directly read/write a file on sd card without cache. I can use "posix_fadvise" to achieve the purpose on Ubuntu I try NDK to make the function call, but it seems disabled on Android How can I do?
View 4 Replies View RelatedIs there a right associated with write/read access to the sd card that needs to be set in the manifest.xml file? I'm currently trying to write to the sd card using a standard FileOutputStream here:
FileOutputStream out = new FileOutputStream("/ sdcard/images/"+imageName);
bmp.compress(Bitmap.CompressFormat.JPEG, 90, out);
But it doesn't seem to be working. It just says the location isn't found, which can happen if there are no permissions to read/write to the location.
As a newbie, I have been reading posts in learning how to do different functions.Using the Hello World example, I added a textview object to this application but the results come back as false on the screen.
View 8 Replies View RelatedI developed a cramfs rom for the np7 after user dochoppy found root for the nextbook premium 7 tablet, but he then converted to ext3 which because its packed with features will be more popular. So I am trying to edit his ext3 rom in Ubuntu 11.10 and here is what I do:
1. Copy and paste system.img to desktop
2. Create a folder called system on desktop
3. In command prompt:
cd ~/Desktop
Sudo mount -t ext3 -o loop system.img system
(Asks for pw)
4. Doc said something about only being able to edit as root, so after some Googling I find out how to create a program that grants root.
5. (Open "run as" program) then I type "nautilus /home"
(Asks for pw)
6. Navigate to mounted system and I have read/write privileges (but only in this window)
7. View the system mount properties, and it says I have 14.2 mb free space on device
8. Delete files throughout the system folder to make room (but when I refresh properties, free space increase doesn't show)
9. Try to add my own files after deleting some others, ans rather than using the increased space, it just fills the fourteen megs before telling me "device is out of memory "
why is the system not physically making the proper system increase and decreases.
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 am trying to create a file ,if it doesnot exist and tried to write some data to it. The same program I did in java, it was running fine.But when I try to do the same thing in Android I am getting NullPointerException at the place where I am trying to write data to file. And also, I did not find any new file in the current directory .
View 2 Replies View RelatedMy program contains a file with the name "size.text", which contains just a word "15". If a user choose a value from a spinner,say 17, then the chosen value should be stored in the file and replace "15". I have added the permission to the program <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission> But somehow i can not make the chosen value be written to the file.

View 8 Replies View RelatedI am creating an application for the android, and would like it to be able to read a text file via anonymous FTP. I've tried URLConnection, but it doesn't seam to be working. After some Google searching it appears that URLConnection doesn't always work with some FTP servers. All of the java FTP connection libraries I've found require you to download the file to a local location before reading it. However I would like to have the same functionality as URLConnection in that I can just use the following similar code...

View 1 Replies View RelatedI am trying to read a file "words.txt" from a resource. It is a very simple, but large (2 MB), text file that I want to read line by line. I have put the file into /res/raw/words.txt, and try to open it with the following code:
CODE:...................
However, I get a java.io.IOException. This is not a "resource not found" exception, so the resource is opened correctly, but the readLine() produces the error.
I tried using the InputStream itself, with the result that read() produces -1, which stands for EOF, as if the file was empty.
I have a text file added as a raw resource. The text file contains text like:
a) IF APPLICABLE LAW REQUIRES ANY WARRANTIES WITH RESPECT TO THE SOFTWARE, ALL SUCH WARRANTIES ARE LIMITED IN DURATION TO NINETY (90) DAYS FROM THE DATE OF DELIVERY.
b) NO ORAL OR WRITTEN INFORMATION OR ADVICE GIVEN BY VIRTUAL ORIENTEERING, ITS DEALERS, DISTRIBUTORS, AGENTS OR EMPLOYEES SHALL CREATE A WARRANTY OR IN ANY WAY INCREASE THE SCOPE OF ANY WARRANTY PROVIDED HEREIN.

But when using the DDMS perspective, "File Explorer" View, I can't see anything in the "data" directory, I'm assuming because permission denied. Is there a way (short of rooting my ion device) to read what's in that text file?
Is there perhaps an android app for developers that will show the contents of the file? It would seem there would have to be some way of reading the file without rooting the device, otherwise why does the o.s. write it out? How can I read this file?

View 1 Replies View RelatedActually I am new to android. I want to create a .txt file programatically, save data to it and then retrieve the data. I had write one application for that but when I run it it creates file under data/data/ <myPackage Name>/files folder , I can see only size of this file but I can't open it. but when I deploy the application on mobile then there is no any file created. If i supplied path like FileOutputStream fOut = openFileOutput ("/sdcard/ deore.txt",Context.MODE_WORLD_WRITEABLE); then it throws Exception. So, please tell me where the actual file is saved under the phone and how to open it.
