General :: Temp Directories In Android File System

Apr 4, 2012

Are there any temp, volatile directories in the Android file system that get wiped once the device is off? In Linux we have /tmp, but this doesn't seem to exist in Android.

Android :: PackageManage - Couldn't Copy Package File To Temp File

Jan 12, 2010

We are suddenly unable to install our app on G1 developer phones with 1.6. Works perfectly on emulator. When installing the app we get:

Installation error: INSTALL_FAILED_INSUFFICIENT_STORAGE Please check logcat output for more details. Launch canceled!

And logcat:

PackageManage: Couldn't copy package file to temp file.

What does this mean? We checked that there is actually room enough on the phone.. We tried reverting the code to a revision that worked previously, but are getting the same error.

Android :: Create A New File Together With Missing Parent Directories

Jun 22, 2010

When using

file.createNewFile();

I get the following exception

java.io.IOException: Parent directory of file does not exist: /.../pkg/databases/mydb

Android :: Alternative To Recursive File Deletion In Directories

Jul 6, 2010

CODE:.............

I'm currently using the above code to create a folder which is used to temporarily store images that the app uses later. deleteDir is just a generic recursive file deletion to empty a directory. Is there a better way to do this than to delete everything? Ideally I just want a temp folder that empties when the application closes.

HTC Desire :: Certain Files - Directories Visible In File Manager - Not Windows XP

Nov 20, 2010

I successfully partitioned EXT3/FAT32, rooted, and flashed Defrost.

Now a strange thing is occurring. I installed an off market app, but I can only see its folder in Android's File Manager, not in Windows XP.

This is going to cause me serious problems because I need to transfer some files into that folder from my PC.

How can I access this App's folder in Win XP?

General :: How To Access Android File System

Sep 25, 2013

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.

General :: Restore Android Deleted System File?

Jun 11, 2012

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?

General :: Android Won't Boot After Modifying System File

Sep 28, 2013

I have a HUAWEI Y300-0100, and it comes with a funny feature: every time it can't connect to WIFI a popup message appears saying that if you switch to data plan charges may apply.

I am constantly switching between WIFI/no-WIFI zones so that message really bothered me, and I searched a way to disable it.

Presumably, the only way to do that is by modifying a system file called "build.prop". I already had my phone rooted so doing so wasn't very hard.I used Jota+ to change a setting from "true" to "false" (ro.config.hw******), and saved the file in the root of the SD card. Then, with ES File Explorer, I renamed the "build.prop" in /system to "build.prop.bak" and copied there the "build.prop" I previously saved in the SD root.All seemed to be fine, except that after rebooting my phone it could not get past the HUAWEI logo.

Android recovery mode seems to work, but I don't know how to use a lot of its options nor I want to do a Factory Reset if there's a better alternative.Is there a way to modify system files before booting Android? I really would like to try to delete the "build.prop" file and rename the "build.prop.bak" back to "build.prop".

General :: Can Mount Android File System Image?

Dec 10, 2013

So after a failed attempt to upgrade from CyanogenMod 10.1.3 to 10.2, I was unable to access /data or /sdcard because both systems were encrypted. I ended up having to factory reset my phone because it refused to co-operate or let me access my files. However, before I did that, I was able to run

Code:
adb shell "dd if=/dev/block/mmcblk0p2" > data.img
and

Code:
adb shell "dd if=/dev/block/mmcblk0p3" > sdcard.img

Which appears to have copied the raw partition images from the phone (at least, they're the right sizes).

According to my reading, Android (and, I'm inferring, CyanogenMod) encrypts filesystems using dm-crypt, with a AES-CBC ESSIV:SHA256 cipher, with the key being derived from the password using PBKDF2. Knowing the precious little I do about encrypted file systems, my guess is that if I configure the image in cryptsetup to create a drive mapping, I can mount the mapped drive and recover the data from the images.

According to /fstab.herring on my ahem, fresh, install of Android, the /data partition is in ext4 format whereas the /sdcard partition is vFAT. So, once I've gotten through the encryption on the partition images, they should mount normally, right?

I know that dm-crypt accepts plain, LUKS, LoopAES and TrueCrypt device formats. I'm inferring from the PBKDF2 extension that Android goes the LUKS route for encrypting. Is this conclusion correct?

Whether it's possible to decrypt a dumped android image? I'm really hoping that the cypher information is stored on the file system and not on some key file that I nuked in the factory reset. If it can, in theory, be decrypted, am I using the right tools to approach the matter? If so, I'll continue fiddling with cryptsetup and mount, but no sense in wasting time if it's an impossible task.

General :: Android SDK Installed From Multiple Sources - System Cannot Find File Specified

May 18, 2012

I've searched to no prevail. id like to start developing apps but am having issues getting the environment set up. I have the jdk properly installed.

issue 1 (main major ):

I've installed the android sdk from multiple sources, but when i try to start sdk tools, the command prompt flashes/ opens briefly and i get this message:

"Failed to execute toolsandroid.bat: The system cannot find the file specified."

Do i need to change a PATH variable or something...

I cannot get eclipse to run. when i try to open the exe file ( because there is no short cut icon...?) it gives a message about not finding a companion library... ive try to change the properties in the file that is supposed to fix it, but it was already set the way its supposed to be. this is not major as i can use a different IDE.

so im completely lost as to th sdk tool. I just tried adding the file path to the android sdk ( PATH variable) and it still did not work... I also just tried start the android,bat file and the cmd promt flashes briefly saying somthing about xcopy is not an operable command...etc couldn't read all of it... I am on windows 7 home premium

General :: SD Card Blank Or Unsupported File System

Jul 6, 2011

Seen this error. My sd card is not readable on any android phone or computer ive tried it on.

What I think broke it was the NEW SD CARD storage optimizer by Kalyani, I opened it up after downloading off the android market and used a feature called file explorer. It took forever to read all the files on my card and eventually I closed it out before its completion and immediately noticed my sd card is now inaccesable.

Is that error fixable or should I throw out the card?
