I'm trying to save a file in a subdirectory in Android 1.5.I get a exception saying I can't have directory separator in a file name ("/"). I'm missing something of working with files in Android..I thought I could use the standard Java classes but they don't seem to work.I searched the Android documentation but I couldn't fine example and google is not helping me too.I'm asking the wrong question (to google).

I wrote a file to the sdcard, but it failed as follow:String sdcardFIle = "/sdcard/xxx.txt" FileOutputStream fos = openFileOutput (sdcardFile, Context. MODE_ WORLD_ WRITABLE ) ; openFileOutput failed, because fIle "/sdcard/xxx.txt" contains a path seperator. It is so strange. Is there another way to handle the situation?

View 2 Replies View RelatedI m using Android 1.5 my data directory does'nt have the read/write permissions
System.out.println("DAta can write??--->"+Environment.getDataDirectory().canWrite());
System.out.println("DAta can read??--->"+Environment.getDataDirectory().canRead());
So please suggest me how to provide permission for the data directory.
What m trying to do is to create a file and add some content to it iin the Data storage of the emulator like as below
private void writeToSDCard() {
try {
File lroot = Environment.getDataDirectory();
if (lroot.canWrite()){
File lfile = new File(lroot, "samplefile.txt");
FileWriter lfilewriter = new FileWriter(lfile);
BufferedWriter lout = new BufferedWriter(lfilewriter);
lout.write("XXXXXXXXXXXXXXXXXX");
lout.close();
}
} catch (IOException e) {
Log.e(m_cTAG, "Could not write file " + e.getMessage());
}
}
I need to be able to write textfiles to the root directory of my Android device (as this related questions explains).
Can I change write permissions for root directory / and if so, how?
I tried pushing a file using adb, but it said file system was read-only
Its pretty annoying that I cannot control my own device, that everything is so restricted
EDIT 1:
This thread has evolved into discussing Sygic Navigation and their API, which seems to be wrong when it comes to the Android platform. I have some other questions that discuss Sygic and their navigation software.
How to remount /sdcard directory to read/write on emulator?
I read this:
http://android-tricks.blogspot.com/2009/01/mount-filesystem-read-write.html
But i don't know how to apply that to remount /sdcard directory in read-write mode?
I'd like to know if there's a way to write files into the main directory just before the system shutdown, something like this:
End all processes (-> unmount disks?) -> mount /sdcard rw and / rw -> copy files from /sdcard to / -> unmount disks -> shutdown/reboot
Same with boot image (flash, in this case, and not copy / mod files)... is it possible? Or do I require to boot into recovery for these operations? I know I can remount as rw my system directory via ADB
Also, is it possible to do the same thing with the build.prop file? This, or during startup (before mounting partitions with standard permissions).
Of course, this having root (but not a special kernel to enable this kind of "before mounting" thing).
How do I create a shared directory with read/write permissions to all applications installed on my phone and that is not on the sdcard?
I tried that :
File f = new File("/tmp");
f.mkdir();
but it is not working.
Is it possible to write data or create folder in system directory like /system/media/audio/alarms. i.e other than our respective package.
View 2 Replies View RelatedI am using following to code to create a directory
private static final String TRIAL_DIR_NME="trial";
File dir = getDir(TRIAL_DIR_NME, MODE_PRIVATE);
Now I want to create a custom file inside this directory. Basically I want to write "trial start date" for app and then compare that date to determine if trial period has expired.
Is it possible for the App to create a new file/asset and write this into the /assets directory. The reason being, that's the only way I can tell webkit will load a local file/resource.

View 2 Replies View RelatedI am new to Android and creating my first application.I want to create a file in the current directory. Basically I have a file bundled with aplication package as raw resource. I want to make a copy of this file in the current file. The reason to create copy in current directory is that I want my file reading code in native java, portable code.So my query is how can I create a file on current directory? The location current directory is important here as I do not want to make use of device specific hardcoded path or any Android API while reading the file. This is so I want my file reading code portable.

I have tried using OutPutStream out = new FileOutPutStream(fileName); out.write(byte [], 0, length);This way always returns Parent directory or File is not writable.I have also used openFileOutPut(fileName, MODE_PRIVATE) method but this method works properly if it is called from the same class which has extended Activity and I am writing to the file in different class and that too in different thread.I have tried to get the Application Context through getApplciationContext and call openFileOutPut method but still theres something wrong that I am doing.So please can someone suggest me a proper way to write to a file.

View 2 Replies View Relatedwhen I run this code, it starts playing all the audio files in the assets directory, in alphabetical order instead of just playing the audio file I requested. What am I doing wrong? Is there a better way to play audio files from the assets directory?Is there a difference between keeping audio files in the assets directory and keeping them in the res/raw directory? Besides the fact that they don't get ids if they are in the assets directory. If I move the audio files to the res/raw folder then I have a problem with reusing MediaPlayers because there is no id parameter for setDataSource(). I can't find a good guideline for handling this kind of problem.

View 1 Replies View RelatedI'm trying to write a file from an Http post reply to a file on the sdcard. Everything works fine until the byte array of data is retrieved. I've tried setting WRITE_EXTERNAL_STORAGE permission in the manifest and tried many different combinations of tutorials I found on the net. How my app writes file is by using a thread. Specifically, a thread is invoked from another thread when a file has to be written, so giving an activity object didn't work even though I tried it. The app has come a long way and I cannot change how the app is currently written. CODE:..................

View 8 Replies View RelatedThis should be trivial, but for whatever reason I can't find any easy way to do this. Coming from C# where this is a 1 line call, I don't understand why Java makes this so complicated, and on top of that android leaves even that out of its libraries. Anyway all I want to do is write an
org.w3c.dom.Document
that I have populated to a xml file. It should be as easy as opening a stream and writing document.toString(). But that doesn't work. My hope is I'm just missing something.
