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.

Android :: Write / Read Access To SD Card In Manifest File

Mar 1, 2010

Is 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.

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).

Motorola Droid :: How To Access File Directory?

Dec 25, 2009

I downloaded a PDF file to my Droid.I can see that it is in the "Downloads" folder when I mount the Droid to my laptop via the USB.My question is, how do I access this file from the phone?I can't get to the directory to try to open it.I can access the PDF through my Gmail account using the Preview option. However, I wanted to save the file to the SD card. So, I searched this and another forum on how to do that and the only way I could find was to access my gmail account through the browser and download. I did this and the file was put in the Downloads folder on the SD.How do you access the Downloads directory and for that matter, any directory that you may want to create on the SD?

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 :: 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?

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 :: Force To Create A Shared Jar Library?

Jul 30, 2009

I have several apps (each in its own apk, process etc) running at the same time on user's device.

these apps are all linked to a single common jar file (internally devloped) which contains a large portion of their overall code size.

is there a way for me to force Android to make this common jar load only once (e.g. into shared memory)?

the reason we want to do it this way, btw, are to reduction of each of the single apps memory intake, on disk footprint and possibly of their startup time.

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?

Android :: How To Read / Write SMS Delivery Report Setting

Mar 25, 2009

I want to know how to get SMS Delivery Report setting which is stored in the /data/data/com.android.mms com.android.mms_preferences.xml. I wrote a application to read it with the following code:

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this); boolean requestDeliveryReport = prefs.getBoolean( "pref_key_sms_delivery_reports", true);

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.
