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");

}
} catch (IOException e) {

Android :: Need To Read Trace - Text File /no Data Directory

Sep 25, 2009

Sometimes in LogCat I'll see Wrote stack trace to '/data/anr/traces.txt'

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?

Android :: Upgrade With SD Card Write Permission

Oct 23, 2009

If you have an app that targets 1.6 ( using targetSdkVersion=4 ) and that is still backward compatible with 1.5 (using minSdkVersion=3) , and it has the new WRITE_EXTERNAL_STORAGE permission because it writes to the SD card, there is a problem when the OS is upgraded to 1.6. If a user has Android 1.5 with the app installed, and then gets Android 1.6, the permission is not granted and writing fails. The issue can be solved if the user re-installs the app. I have not experienced the issue myself, but a few users have reported it. Can anybody else confirm this. There is not much that can be done about it, but it would need to be adressed if there is another OS upgrade.

Android :: Can I Change Write Access For Root Directory

Jan 18, 2010

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.

General :: How To Write Files Into The Directory

Jun 21, 2012

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).

Android : How To Read/Write .CSV

Dec 15, 2009

I'll open with, I googled this thing like crazy, searched anddev and a few other boards (including this one) and can't quite find what I'm looking for.

The predicament : all CSV examples are in reference to contacts, and the file read/write posts (the ones that I need) make the assumption that I am not a beginner and most don't even post any code leaving me nothing to learn on.

The hopeful solution : a link to a solid example of simply how to write to a CSV with my own custom fields and values, and how to read a CSV and load said values.

Android :: Permission Error On Read Contact Off Of Emulator

Feb 22, 2010

I am trying to do is read a contact off of my emulator and display it to the screen. I can't seem to resolve this error. Both of my packages (com.msi.ibm.tutorial and .MobileServiceCallContacts) have the permission READ_CONTACTS set in their manifest xml files. So any ideas as to what I've got wrong? Here is the error message from eclipse console if it helps, it's not helping me, but I'm a little rusty at this and completely new to Android development.

Samsung : Read And Write UTF-8 To Disk On Android?

Apr 29, 2010

I cannot read and write extended characters (French accented characters, for example) to a text file using the standard InputStreamReader methods shown in the Android API examples. When I read back the file using: the string read is truncated at the extended characters instead of at the end-of-line. The second half of the string then comes on the next line. I'm assuming that I need to persist my data as UTF-8 but I cannot find any examples of that, and I'm new to Java. Can anyone provide me with an example or a link to relevant documentation? Code...

Android :: Application That Can Read And Write Txt Files To SDCard

May 3, 2010

I have an application that can read and write txt files to the phones sdcard. By using this code for reading files:

@Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); mFileNameOpen = files.get(position);
String st = null; mVector.clear();
notepad.mNewEmpty = false; try { File f = new File(Environment.getExternalStorageDirectory()+"/ notepad/"+mFileNameOpen); FileInputStream fileIS = new FileInputStream(f);
BufferedReader in = new BufferedReader(new InputStreamReader(fileIS));
do { st = in.readLine();
mVector.add(st);
}while(st!=null); in.close(); ...
} catch (FileNotFoundException e) { e.printStackTrace();
} catch (IOException e) e.printStackTrace();

and this to write them:
try { File root = Environment.getExternalStorageDirectory();
File fileCheck = new File(root, "/notepad/" + fileNameSave + saveExtension);
boolean exists = fileCheck.exists();
if (!exists) { if (root.canWrite()) { File textFile = new File(root, "/notepad/" + fileNameSave + saveExtension);
FileWriter textWriter = new FileWriter(textFile);
BufferedWriter out = new BufferedWriter(textWriter);
out.write(SAVEAS); out.close(); written = true;
} else { written = false; else { written = true; showMaybe = 1; showDialog(DIALOG_SAVE_EXISTS);
catch (IOException e) {Log.v(getString(R.string.app_name), e.getMessage());

This has been working fine on my Tattoo and all the emulators I've tried this on. But it does not seem to be working on moto droid. Is there something different to consider with moto droid? Or have I missed something in the manifest maybe?

Seems it does not work, it always returns the default value which is "true". Does anybody know how to read/write the SMS Delivery Report setting.

Android :: Fastest Method To Read / Write SD Card?

Jul 18, 2010

There are a lot of different classes that can be used in various ways to read/write to files in Android. For example, you can make use of java.nio.ByteBuffer, FileOutputStream and BufferedOutputStream. Are there any general guidelines for what to use to read/write quickly to the SD card? For example, BufferedOutputStream seems as if it should make things faster but I'm unsure the buffer size should be set for. Specifically, I want to read/write byte arrays that are ~1Mb in size as quickly as I can.
