General :: Creating Bootable SD Card From Within Android
Apr 6, 2013
Is it possible to do this within Android?
At the moment I've this rooted phone running ICS, an SD card, an SD to USB reader and a netbook that once ran windows 7 until an hour ago. Oh and no working computer access for a few days.
I've installed a couple of versions of linux on PC's in the past, mainly as quick fixes between windows installations as I've proved myself too much of a novice to use it full time, so I know it can be done from an SD card easily enough should you be able to make one bootable with linux installed.
As I've only got this phone for a few days, would it be possible to do the above directly from this device?

I plan on buying a new 32gb sdcard for my Xperia ray. What i plan to do is letting the phone use most of the space on the sd card but creating a second partition for a different purpose.
The purpose is to use that partition just like a normal windows(ntfs or fat) usb disk and eventually making it bootable for PC's. I carry my usb stick with me that i made bootable via easyboot and installed the tools i need which i wanna get rid of if my phone has the same capabilities.
Questions are
-Will a pc recognize that partition as a bootable device and eventually boot?
-If yes, will i need to set anything on my android such as usb debugging etc. after connecting?
-will that partition be independent from the android partition? (i guess this is a low possibility since the partition is on the sdcard and that is mounted to the android os, but may be android calls the partition sdcard thus not hugging the second partition)

I want to create a file on the SD-Card and later save a CSV file in it. From surfing around I noticed that there seem to be two ways about going about it:If you're using API Level 8 or greater, use getExternalFilesDir() to open a File that represents the external storage directory where you.................................

I am trying to have my app create a directory on the root of the SD Card, if that directory does not already exist. When I run the app, the "Creating Home Directory..." toast notification displays, but the directory is not created... What am i doing wrong?? (P.S. permissions are set for writing to external storage)
CODE:.......
Here is my Manifest file:
CODE:...........
I tried this as well, it didn't work, but it might be a step in the right direction as it creates the directory and populates it with a file from res/raw all in one step:
CODE:.........................

I'm currently only testing things in an emulator due to not having an Android device as of yet. I'm honestly holding out for some of the new 1 Ghz machines to come out and do some comparisons. Anyway, I would imagine one would easily be able to make whatever folders they choose on an sd card, but on the emulated one, I can only seem to push entire folder contents or single files to the root. The adb help doesn't appear to have a command to make a folder. Is this not possible, or am I just missing something?

I would like to write a file to the SD card from my application, but the following code throws an IOException when debugged on a T-Mobile G1:
String p = Environment.getExternalStorageDirectory() + "/log.txt"; File recfile = new File(p); recfile.createNewFile();
The last line throws an IOException with detailMessage = "Cannot create: /sdcard/log.txt". The MOUNT_UNMOUNT_FILESYSTEMS permission is set in the manifest. And yes, I really do want to write to the SD card; I don't want to use the logging features Android includes for this particular application. The Android documentation does not seem to give any specifics on how one might write files to removable storage in "Data Storage" under "Framework Topics". What am I doing wrong, or where can I read more about this topic?

I tried to make a goldcard for rooting my HTC Hero (Three UK with latest ROM) over the weekend, but had no luck - it seems the memory card I own (an 8gb Kingston card from ebay, so may be a fake) doesn't work.
Can anyone recommend a memory card brand & size that will *definitely* work for creating a goldcard?

LG G Pad 8.3 running stock Android 4.2.2? How to create a new user. It's like LG forgot to show the "Add User" button under "Settings -> Users". Unfortunately there are no LG G Pad forum on XDA, and LG do not have any customer support. They basically do not pick up the phone. And since it's a new device, there are not much information about it yet.

I noticed in the newer releases of busybox there's no 'zip' command anymore. I'm running busybox 1.19 on my Incredible.
I have been using this command to create different bootanimation.zip files from my phone but am wondering if there is an alternative command I can use from within Android. I've tried tar -cvzf but I believe tar archives/compresses the files differently and renaming the extensions to .zip does not work.

I'm trying to create an always-op-top button/clickable-image which stays on top of all the windows all the time. The proof of concept is here URLs...I'm following this example code URL....
I have been successful and have a running service now. The service displays some text on top left corner of screen all the time while user can freely interact with rest of apps in normal manner. What I'm doing is subclass ViewGroup and add it to root window manager with flag TYPE_SYSTEM_ OVERLAY. Now I want to add a button/clickable-image in place of this text which can receive touch events on itself. I tried overriding "onTouchEvent" for the whole ViewGroup but it does not receive any event. How can I receive events only on certain parts of my always-on-top view group?
Code:
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.graphics.Canvas;
[code]....

I cannot play my mp3s without one or two songs repeating over and over, before going to a new song, then the player goes back to the same repeated ones. I noticed that extra files are being created continuously in the mp3 folder. Even if I make a play list the player still manages to go back to these invader files. Is that a micro sd card or android issue. I first notice it after I install ics on my SGS I9000. Now I am JB (I9300OXADLI8).

I can't create a new APN in my phone. I own a samsung galaxay star GT-S5282.
I tried using giffgaff, but when i save the APN that giffgaff made, it isn't there. And I tried doing it manually too. It's not there when i press save.
I tried using APN backup and restore, and when i open the app, it says "Unfortunately APNs cannot be restored or deleted on this device because android 4.0+ does not allow 3rd party apps to write APN settings."
I already checked the unknown sources in settings>security>unknown sources.
I don't know what to do to create new APN.

I just transferred a bunch of pictures (over 2000) from my ipod to my mytouch 4g slide. I had them all in neat little albums on the ipod and i would like to do the same on my phone. Problem is i cant figure out how, other than putting the files into separate folders on my sd card, which i don't like because i like to have a general folder of all of them together with separate albums for specific things, and sometimes a picture would go into more than one album. Is there an app or a way to do this on my phone, I don't mind if the app creates copies of my pictures as long as the original files are left untouched. And is there a way to organize my pictures by name rather than date? Because when I transferred them it don't keep date it was added but rather the date i copied it, and when organized by name its correct because of the numbers in the file name.

i want to create a flash-able zip of PA's HALO for my stock and rooted nexus 4. For all i know i must take the commit files and merge them in my recompiled ROM's folder, compile them and flash (or maybe try to run it in an android emulator first?) Well i'm facing a lot of problem: 1 i can't even get git commit files (yes i have git installed) 2 even if i succeed to get the files and compile my ROM and it all works flawless i don't know how to make HALO as a flashable mod.

I've been looking up everywhere as to how to make apps, but everything i see is too complicated and i don't understand it. What i want to do is create a simple app that has a bunch of pages that you swipe to get to the next page, each page will just be a picture with a single button on it that links to some text. How would i go about doing this? (i have no programming experience)

I have recently just switched from a iPhone to HTC One, I came across some really cool home screens (such as on minimal android), I didn't know you could customize these, so now i am very eager to try them out myself. However clicking through some of the home screen instructions, there is a section called "ROM", does this mean the device has to rooted first?

First noticed a problem when I got a warning message that I was running out of storage space on the phones memory. When I checked I found literally thousands of copies of the same photo in the S4PhoneDCIMCamera folder. I delete them all but the phone continues to make a copy approximately one every minute which I have to constantly delete to free up storage. what is making the copies?
