Android :: Use Vold(New Volume Manager Daemon) To Automatically Mount Sdcard When Device Startup
Mar 29, 2009
I am porting android to my own device now. I checkout the latest source code from android.git.kernel.org. I have successfully compilated filesystem images and burn those images to my devices. But i couldn't automatically mount my sdcard when android startup. The / sdcard directory is empty when i used 'ls /sdcard' command. I have copied the vold.conf file from development/data/etc direcotry to my device(/system/etc), but it's invalidated. When i read the source code(vold), i found the vold daemon relate to switch driver, device mapper driver and android gadget driver. Are there some document or information about how to configurate android kernel to support vold new volume management and wirte right vold.conf configuration file?

I'm trying to get my SD card encrypted and I've been able to successfully mount the luks volume, but due to the way that Jelly Bean 4.2 (Cyanogenmod 10.1) presents folders to user apps, only my terminal emulator can list the files.
In my troubleshooting, I've found that a standard mounted SD card is first mounted to /mnt/fuse/sdcard, and then an abstraction layer through a fuse driver mounts it to /storage/sdcard1 in order to set file permissions that all apps can access.
Right now, I'm trying to trick my vold.fstab into mounting the dm-5 device that appears in /sys/devices /virtual /block when the dm-crypt volume is opened. Unfortunately, since the original sys folder for the sd card is in /devices/platform/msm_sdcc.2/mmc_host/mmc1 format, I'm not sure where to direct vold.fstab to check the presence of the dm-0.
I'm aware that as asec apps are installed the dm-5 can change to something higher (dm-6+), but I'll cross that bridge once I get part one working.

I have an android device: it's a stick connected to my TV, running android 4.1 rooted. The stick is an MK808B. The stick is connected to my TV's USB so that when I turn the TV on, the stick boots and when I turn the TV off, it shuts down completely.
I am looking for something that automatically connect the stick to VPN when I boot it. I would preferably use VPN over L2DP, although I'll take PPTP if there's no other option. I can't use openVPN because my ROM's kernel doesn't have TUN. There are two ways to approach this: one way is to connect it on boot, another way is to connect to VPN when the stick connects to a wireless network because my stick is stationary and always connects to the same wi-fi network.

I replaced my original sdcard with a sandisk 16gb card. Everything went well until I started getting these blasted read on errors. Earlymon suggested a fix from another board but I don't have a stand alone card reader so I couldn't do it that way.
I was wondering if I just backed up all my stuff from my sdcard to my iMac and then just reformatted my sdcard via the phone, would that solve my problems?

I've noticed that some users have not found my app's preferences sub menu, so I want to show that sub menu when the user first-time-ever starts the app.
Since onCreateOptionsMenu() would not have been called yet, how can I programmatically show such a sub menu?
BTW: openOptionsMenu() is not what I want because I want to open a sub menu. I suppose its part of the solution though. However, I get an exception when I call it:
Caused by: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not valid; is your activity running? at android.view.ViewRoot.setView(ViewRoot.java:468) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java: 177) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java: 91) at android.view.Window$LocalWindowManager.addView(Window.java:424)
even though, at the same point in the code, I can successfully open new AlertDialogs.

I formatted my internal sdcard to exfat by mistake while trying to simply format it(for some reason windows defaulted to exfat instead of fat32) now my sdcard won't mount and I can't format it in windows and can't mount it, I could get it back to fat32 and working again.

Currently, ICS on my sgs2 shows my external card as mounted with empty contents (in storage settings). Both /mnt/sdcard and /sdcard point to the internal sdcard storage. Where is my external card mounted? GT-I9100

i figured out how to make the USB cord find the droid when you plug it in the comp, you drag down the notification menu and hit "mount" and it pops up the folders on windows.. i got that part
but i was wondering if there was a way to just make the folders pop up automatically so you don't have to drag the notification menu every time and hit "mount".

I am facing a weird behavior these days with my new HTC legend. My ringer volume gets muffled automatically after 5 or 10 sec on getting a call. I have already disabled "quiet ring on pick up" feature. Then also this problem is coming up. I have googled this n come to know that i am not the only one. Some folks have found a workaround that if they choose "WCDMA only" network in network settings then this problem is not there. But I don't have 3G connectivity in my area. What should I do? I have note down the logs just after this problem. It shows some errors:-
W/CallNotifier(144)
CallerInfo query took too long,manually starting ringer
CallerInfo query took too long,falling back to default ringtone
E/jBtlAgHandler(144)
"JBtlAG context is disabled"
E/BT HS/HF(144)
mjBtlAgHandler.sendRing() failed

I am trying to change ringer volume but I am a bit confused. I can reach the volume_ring level by using the code:
String vr = System.getString(this.getContentResolver (),System.VOLUME_RING);
However it says in the explanation "Ringer volume. This is used internally, changing this value will not change the volume. See AudioManager." How can I change Ringer Volume? What should I do?

An app or mod that will use the microphone to sense the amount of noise around you and adjust the notifications accordingly - that is to say when its quiet, next to my bed and I am sleeping I want it to be all quiet sounds - but when I am working and there is fan noises and other stuff that is louder then normal I want the notifications to be loud - but if I walk into the break room which is quiet I want it to be quiet again - or if I am listening to music in a room or car turn up the notifications so I can here them and back down when not. You know take a sound reading and turn up or down the volume of the notification that is happening at that given time.
Only problem being when its in your pocket it will always seem to be quieter then normal so they will be quiet also, so there would need to be something to listen to the sound and determine if its being muffled by a pocket or whatever and turn it up then - if playing a sound and analysing that sound it should be able to determine what environment the phone is in, like a pocket or bag that will make it quieter. I am not even sure if i am describing this properly but I know someone can probably figure it out, but it might have to be something the manufacturer does, like that phone that has 2 microphones to auto cancel out background noises like a bluetooth headset.

Coming from WinMo I've been using the PPCProfiles app and it has been a God sent to me.
What that does is manage the phones volume automatically. You set a template and it switches from silent to normal automatically and vice versa.
I used it to switch my phone to silent when I went to sleep and then switch it back to normal volume before my alarm (on the phone) would ring in the morning. It is very useful if you use your phone as an alarm, otherwise obviously you could switch manually before going to sleep and after waking up.
So, is there an APP like that for Android?

I need to write a fairly simple .csv file to the device's sdcard (so it can then be emailed via Intent). The below code does not write the file.
CODE:...........
More code here:
I flush and close out_stream. I can even seem to be able to read from the file on the device (printing above output, using fileinputstream, to an edittext.
How can I get to this file on the sdcard?

I'm looking for something that will close apps (and the commands that make them relaunch) in an automatic way (i.e every time the said app is beign activated).
I need something non root ( the apps being closed are not an internal part of the rom), preferably free, and that is trustworthy (security wise).

I'm working on a CM port and currently facing issues with vold. For some weird reason, vold isn't mounting storage devices as it should. Here is my current vold.fstab file:
Code:
dev_mount flash /storage/sdcard0 auto /devices/platform/mtd/mtd8/media nonremovable
dev_mount sdcard /storage/sdcard1 auto /devices/platform/AMLOGIC_CARD/card_host/memorycard0.
Using adb I can confirm that everything is mounted correctly and also I can browse the files. Using applications (even MediaScanner) fails with permission errors. This is how I'm creating the storage folders, for user/permissions reference:
Code:
# Create mountpoints
mkdir /mnt 0775 root system
export EXTERNAL_STORAGE /storage/sdcard0
export SECONDARY_STORAGE /storage/sdcard1
mkdir /storage 0550 system sdcard_r
mkdir /storage/sdcard0 0000 system system
mkdir /storage/sdcard1 0000 system system
[code]....
I have also noticed that the system reports different owner/group/permissions through adb and Terminal Emulator. Here are the outputs:
Code:
root@android:/ # ls -la /storage/
d---rwxr-x system sdcard_rw 1970-01-01 02:00 sdcard0
d---rwxr-x system sdcard_rw 1970-01-01 02:00 sdcard1
d--------- system system 2013-09-05 02:29 usbdisk0
[code]....
I'm suspecting storage_list.xml, but I checked mine and seems correct. Also, it doesn't define permissions, so I excluded that.How can I further debug this? Logcat doesn't show anything useful, everything seems fine with vold.
