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.

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.

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?

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 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'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).

I get a lot of requests in my application to allow for custom icons packs from BetterCut / Open Home. The way it seems to work is you install BetterCut or Open Home, then you can install tons of these free icon packs from the market. Once installed both those apps (and other apps) will poll for those icon packs and use the icons. I want to know how to poll the install applications for the asset folders that are available. I have opened up a few of the icon packs and verified that there is an assets folder in there and they are full of all the icon png files. I've searched on here, other code sites, google, etc., but haven't found any leads.
From the answer below I have written some code to try and list a file from my own projects assets directory but it does not seem to work.
Resources r = this.getResources();
AssetManager a = r.getAssets();
String[] list = a.list("/");
Log.d("test", "Length of / is "+list.length);
for (String s : list) { Log.d("test", s); }
Log.d("test", "Length of /assets is "+a.list("/assets").length);
Log.d("test", "Length of /assets/ is "+a.list("/assets/").length);
Log.d("test", "Length of /assets/ is "+a.list("/assets/").length);
Log.d("test", "Length of ./assets/ is "+a.list("./assets/").length);
Log.d("test", "Length of ./assets is "+a.list("./assets").length);
This is the output:
03-16 12:25:04.591: DEBUG/test(13526): Length of / is 6
03-16 12:25:04.591: DEBUG/test(13526): AndroidManifest.xml
03-16 12:25:04.591: DEBUG/test(13526): META-INF
03-16 12:25:04.591: DEBUG/test(13526): assets
03-16 12:25:04.591: DEBUG/test(13526): classes.dex
03-16 12:25:04.591: DEBUG/test(13526): res
03-16 12:25:04.591: DEBUG/test(13526): resources.arsc
03-16 12:25:04.614: DEBUG/test(13526): Length of /assets is 0
03-16 12:25:04.637: DEBUG/test(13526): Length of /assets/ is 0
03-16 12:25:04.661: DEBUG/test(13526): Length of /assets/ is 0
03-16 12:25:04.692: DEBUG/test(13526): Length of ./assets/ is 0
03-16 12:25:04.716: DEBUG/test(13526): Length of ./assets is 0
I figured out that you can read from the assets directory without actually using the folder name:
InputStream is = assetManager.open("test.png");
I also tried this with an asset in Appliction 2 from Application 1, where the folder path is /asset/icon/image.png:
InputStream is = assetManager.open("icon/image.png");
Next I figured out that you can list a directory inside assets:
String[] list = assetManager.list("icons");
That also works great. The only thing failing right now is how to list the base directory assets.

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?

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.

I've rooted my phone, but I still can't figure out how to access the / directory from my computer. Specifically, I want to be able to open /system/media/audio/ringtones so I can put new ringtones in there. Is there a good way to do this? I tried copy/pasting with astro file maager, but it won't let me paste into that directory, I assume because I don't have permission.

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 have an HT-PAD1051 - seems to be pretty close to the HeroTab M10.
I have rooted the device but can not get access to the root directory in the internal sd card. (There is no external sd card slot on this particular device). Part of teh internal sd card is mapped to a /mnt/ directory and folders in that directory are accessible. But no access to the root directory. So, when I try to flash Clockwork Mod recovery using ROM Manager it fails due to not being able to access the directory.

I even tried flashing a custom rom (Fresh) on the last attempt and it just seems like it is giving me the Sprint stock Rom. Shouldn't the custom Rom look different? Once rooted do I still need to use Unrevoked method to grant superuser access for Apps?

I am using a mt6582m device with kitkat 4.4.2 with supersu. I can use root to write to system, data and cache using es file explorer, can also read and write to any sd card, but apps like titanium backup, online android backup, ram expander can't read/write to sd card.
Eg.1: ti backup read backups, can do all operation except backup and restore.
I had read a lot, changing backup path didn't worked nor any odex file is there. Using v6.1.5.6.
Eg. 2: ram expander can create swap file on sd but can read it saying 'not found'. Swap can be used with cache partition.
Eg. 3: online nandroid backup says pat not vaild.
I had tried, sd fix app, manually editing platform.xml, xposed module to 'handel external storage', change permissions using es file explorer, editing ramdisk.
There is storage/sdcard0 and 1
Also mnt/sdcard and mnt/sdcard2 (symlinked)
Also mnt/media_rw/sdcard0 and 1 (not readable even in es file explorer)
