Android :: File System Root - Name Has Extra Characters
Jun 13, 2009
First I found the problem, then I found this truly ancient post:
http://groups.google.com/group/android-developers/browse_thread/threa...
...with no responses. To browse the file system from the top down I suppose I can simply hardcode the root as a single slash, but I would rather "do it right". Can anyone explain why listRoots returns a root named "/XX" where X is a junk char? It's problematic because that file cannot subsequently be queried for further file system exploration.

I have a android tablet and I have tried rooting it and I get things like "read only file system" and I looked into it and my /system is read only.. Rooting is putting .su in the xbin or bin inside of the /system. But my /system is read only so i can't root my tablet?

Does the X use a FAT32 file system? Is there any way to change this? I'm asking because I have a 4+GB mkv file I want to put on it, but I'm getting a message telling me its too large for the file system. If no way to change, then can anyone suggest a way to make this file small enough to fit?

Then I tried doing Toast's root and got confused at step 2 (the adb step).
Now, I know a LITTLE about what ADB is and that you basically only need it so you can use your computer to type/see things instead of doing it all on your phone.
(This is the thread that I'm using by the way: [TUTORIAL] How To Root The HTC EVO ~ Part-1 / - xda-developers)
1. So, so far, I downloaded SDK package, saw the "tools" folder and see the "adb" file. When I click on it, it pops up like a "command/cmd" screen and disappears. Is it supposed to happen like that? Or am I doing something wrong?
2. Also, in Toast's method, when he says to put the PC36IMG.zip file on the root of your sdcard. What does he mean by that? I'm sure it's something simple but I'd rather be sure how to "put it in the root of your sdcard". Just that mean just right in the front by all the folders?
3. Next thing the page says is: "adb push PC36IMG.zip /sdcard"
I don't know what he means by that. Am I supposed to do something here?
The steps follow this (until it's Rooted) I understand but not this.
4. Then after rooting there are some other steps he has in the original thread that say somethings about "adb shell, adb.. etc"
What do all those mean?

I need to save some persistent data (byte array) in my application.I decided to write these data into a file on the Android hardware.But I cannot create a file under /system/ or /data/.Can any body tell me under which directory can I create a file to save my data except SDCARD(Because We cannot suppose every Android has a SDCARD)?

How to change the fonts on your rooted Droid Eris. I'm not sure if this works for all Android phones, so backup your phone before proceeding. This DOES change key Android files, so be careful. If you brick your phone, it's not my fault.
First of all, go to this website and find a font you like:
1001 Free Fonts - Download Free Fonts for Windows and Macintosh
The file you download should be a .zip, and when unzipped be in the format .TTF. Copy the .TTF file to your SD card. I suggest SDCard/Fonts/. After finding a nice font, download Type Fresh from the Market (free). Also, pick up AndExplorer (free) while you're there. Type Fresh will allow you to change your fonts, and Andexplorer is used as a handy file explorer.
Run Type Fresh, and it will display all the system fonts that Android uses. Touch DroidSans, and it will display a window using AndExplorer. At this point it should request superuser permissions; allow it. Find the folder with your fonts, select a font, and press okay. Press menu and select apply fonts. Allow it to reboot your phone when it asks, and afterwards you should have a nice new font to make your Eris even sexier.

I am developing a photoshop application for the G1 where you can apply different filters to your pictures stored in the pictures folder. So I use a gallery and a cursor to select the picture I want to manipulate, copy the picture to a bitmap so I can perform some filter operations and afterwards save the new bitmap as a new file to the phone. So I figured out that there are basically two options I have to save the image. One is to use the MediaStore.Images.Media.insertImage() method, which generally would work, but I don't want a thumbnail to be created. The second option, which I actually use, is to use an OutputStrem.
import android.provider.MediaStore.Images.Media; import android.content.ContentValues; import java.io.OutputStream;
// Save the name and description of an image in a ContentValues map. ContentValues values = new ContentValues(3);
values.put(Media.DISPLAY_NAME, "road_trip_1");
values.put(Media.DESCRIPTION, "Day 1, trip to Los Angeles");
values.put(Media.MIME_TYPE, "image/jpeg");
// Add a new record without the bitmap, but with the values just set.
// insert() returns the URI of the new record. Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
// Now get a handle to the file for that record, and save the data into it.
// Here, sourceBitmap is a Bitmap object representing the file to save to the database. try {
OutputStream outStream = getContentResolver().openOutputStream (uri);
sourceBitmap.compress(Bitmap.CompressFormat.JPEG, 50, outStream);
outStream.close(); } catch (Exception e){

I have an application that I want to be able to use the userid: android:sharedUserId="android.uid.system", I need to sign the .apk file with the same certificate as the built in system applications, such as the 'Settings' application. I've located the keystore file in my build directory which is: cacerts.bks, and I have the password for this. What I seem to be missing in order to sign my .apk file is the alias fo the keystore. Does anyone know what the alias is? Or is there an easier way to do this that I'm missing.I know this not a standard thing to do, and is perhaps a hack, but I have a client requirement to meet.

I'm trying to re-partition an SDCard on Android, with root access. What I'm trying to do is resize the 5.9GB partition into 3GB, and then make an EXT partition with the remaining space. I can think of two ways to do this, but I'm a bit stumped in doing either of them: 1) Cross-compile GNU parted, and run it on Android to modify the filesystem in place. This would be my preferred method, but I've been trying to statically compile parted using scratchbox and haven't had much luck, and I haven't been able to dynamically compile for Android in scratchbox either. 2) Directly modify the 512 byte MBR using some utility on my computer, and then dd the file on Android. I have a tool to view the MBR (mbrwiz), but I don't know how to edit it. Does anybody have any suggestions for either, or possibly a third route?

My objective is to create a text file in an android file system.
Using java language, I am creating an app. It has a screen with a table of 3columns. Each time a user enters the table row and click on Submit button, the row entry should be created as a separate comma-separated file on an android device. So each time when the table gets updated with new entry and clicks a submit button, a new file is getting created on the device file system. So I am looking for the file connectivity to the internal device memory where I could open the files and access it.
I have done the same in Nokia mobiles using J2ME. But for Android, I am not able to find the device file path.

2 days ago I tried to update my aunts sensation xl and told her that it is better to update its ROM from 2.3.5 to 4.0.3. So i created a google account in phone and added it in order to sync contacts....and after 2 hours, I thought that it has been synced...After upgrading device to ICS, and adding the previous account that i made before upgrading, I was waiting for contacts to restore, but nothing happend.. I opened the gmail account on PC and saw that there was no contacts. So the only way for me to restore the contacts is to find a way to restore them from Phone device. So,is there any software, either on phone or PC, to restore contacts from phone? or is there a way to have access to root folders and files of phone on PC to use a recovery program to restore "Contacts.db" file that was erased while flashing ICS?
