HTC EVO 4G : How Can I Access SD Card / File System?

Jul 2, 2010

Ok just got my EVO yesterday. This is not only my first android phone, but my first smart phone as well. I'm fairly savvy when it comes to computers and techy stuff, but I do have what sounds like a ridiculous question. I bluetoothed some files (songs and pictures) from my old phone to my EVO. It acknowledged getting them and indeed I was able to play them from the notification area after receiving them. However, now I cannot find anyplace to 'browse' the phone folders or the SD card folders so I can find and utilize these files. How do you access the SD card or the file system?

HTC EVO 4G : How can i access SD card / file system?


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 :: 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?

Motorola Milestone :: Blank SD Card (8GB) - Unsupported File System

Jun 12, 2010

My brother just bought a Milestone and he's having problems with the SD card (8gb). What happens is that he put some music on his phone, and with the program Ringdroid, began to cut some songs. Then, the phone began to crash, he restarted it. After restarting, the device didn't recognize the memory, saying "Blank sd card or unsupported system", occasionally rebooting, indicates that it was removed. I have looked in other threads and google it, but found nothing useful. I can't unmount or format it from the phone. And as I have the G1, I put my card (that works) on Milestone and got the same problem, so I think it's not the SD. I've already formatted it, nothing.

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.

Android :: File System Access Triggers - Listener On Android Devices

Feb 19, 2010

I'm looking for some ways to intercept File System Access operations like Read and Write a file. So that i can catch these "events" from an Android App. (background service for ex.). I don't have found any possible "events" and "listener" that i can use to listen to file system access on the device. So, i'm thinking about developping a native application (with the Android NDK) which will intercept these file system "events" and send them to a background service.

Samsung Galaxy S : Recovery Boot Error - Can Not Access To /system/csc/VOD/system

Sep 4, 2010

Phone: UK Galaxy S Issue: Recovery boot error message in red writing

Multicsc : can not access to / system/csc/VOD/system/

Background: I have been trying to root my phone from information found in a youtube video. All went well and the little ninja bloke with the sniper rifle was in the app list. Tried installing busybox and was told that the phone was not rooted�..

I think I ran the root application again and at some point I started getting this error message when in recovery. I have since run the one click root method to unroot the phone and the little nija dude is no longer there. Since I rooted the phone it will no longer connect to my wireless network, it finds the network and attempts to obtain an ip address. After a few min it times out and tries again. When I load the phone recovery the error message is still present.

Let's say you don't have internet access at the moment. Let's say all you have is fresh install of CyanogenMod 9, which for some reason, does not come with a File Manager :

Let's say you have an apk file on your SD card. How would you install the apk file? Terminal emulator, using which commands or another way?

By the way, ASTRO File Manager vs. ES File Explorer, which one and why?

Motorola Droid : How Do You Deny Specific System Access

Nov 13, 2009

I installed the Nimbuzz app today. It has system access to prevent the phone from sleeping. Which really sucks because I can't leave it running in the background so I stay logged on. If I keep the Nimbuzz services running then The display won't time out on inactivity. If you close the services then You can't get the incoming chats.

Is there away to deny certain access to apps but allow the rest and install it? From my experience I've only seen that it's all or nothing.

HTC Incredible :: How To Know Which System DINC Using To Access Internet At Any Given Time

May 14, 2010

New to Android, not new to smartphones. My BB Storm didn't have WiFi though which is the root of my question.

How do I know which system DINC is using to access internet at any given time? For example, if I am at home connected via WiFi is my DINC using WiFi or 3G to connect to the internet? Also, when my DINC synchs up my accts (Facebook, Weatherbug, Native Weather App, Gmail and Mail) is it using 3G or WiFI? Can I set a preferred connection somewhere? I've looked, but can't seem to find something like that.

General :: Why Can't Alter SU Binary To Have System Access Only Instead Of Root

Apr 30, 2014

Imagine a scenario where you have just system access on android , and you want to continually have it, so you use the su binary, with the correct permission and the setuid flag on, and the owner being system, you do:

Code:
chown 1000:1000 su2
chown 06755 su2

you have the ability to change the owner to system as you do when rooting, and you also set the appropriate permission as you do when rooting,

06775 being the permission code to all have execution permission, and the setuid flag on.

But when dealing with system permission that doesn't work. it only works with root.

General :: HTC Desire Z - Can't Access System Partition And Formatting Not Possible

Apr 3, 2014

HTC Desire Z (Vision). I S-OFFed how it's described on CM wiki. Latest radio. About month ago I installed CM 10.1 AlterNdromadus. It worked until yesterday, when it unfortunately installed some system update.

After that phone didn't booted anymore. In recovery it says, that it can't access system partition and formatting is not possible.

I tried connect the phone via fastboot in bootloader, but it also doesn't work. Under windows I have it as unknown device and when I tried manually install drivers from google, it says that they are not compatible with the HW (under ROM it worked before).

I tried also install stock RUU rom (extracted the zip and deleted H-BOOT, radio and recovery) from SD-card (PC10IMG.zip). But it also got frozen on system update.

Here you can see error from 4EXT recovery and CRC images from bootloader.

General :: How To Gain Root Access If Busybox And System App Is Already Installed

Oct 11, 2013

I have a Rockchip RK3188 Tablet with Android 4.2.2, which I need to root ON DEVICE. Actually, the device was already rooted (using a Laptop via the adb bridge), so I already have busybox installed and I have one of my own apps in /system/app. However I managed to delete the su program (yeah great!) and therefore don't have root access any more. I know I can easily root the device again if I connect it to my laptop again, but that is not possible, because the device is at my parent's place and I can't go over there any time soon.

Therefore I want to root the device just with an app. Actually I would only need to copy su to /system/xbin. These are the things I already tried (without success):Framaroot (doesn't work, because framaroot does not support Rockchip tablets)

Writing my own app, which contains su in the assets and using this su for temporary root

Using adb (on the device) for a local connection (adb connect localhost), because if I connect from my PC I automatically have root (doesn't work because Android 4.2.2 has increased security on adb)

Start telnetd via busybox and then execute my commands via nc (doesn't work, because I can't start telnetd in a way that it ends up with a root shell)

My last idea is, that I could maybe gain temporary root access with the app I already have in /system/app. Basically this would be similar to the Master Key Exploit, except that I do not have to fiddle around with the apk and instead install it normally. However I don't know how to continue from that point. I know, I have special permissions if I have an app in /system/app, but which permissions are that? And how can I use those permissions to make /system writeable (and copy my su file there)?

Android :: Application Developers - Allowed To Access System Properties Like Ro.config.sync?

Apr 20, 2009

Google applications do it, and apparently it used to be part of the public API (via android.os.SystemProperties.) How are we supposed to enable/disable sync on the phone? Disabling/enabling roaming is easy, but I'm beating my head against the wall trying to find a non-hack method for disabling auto-sync (much less the granularity that would actually be nice.) Is this intentional by the framework team? Is it a whoopsie that is planned to be changed later?
