Local file encryption app: watched folder & NO Internet permissions? - Android Q&A, Help & Troubleshooting

I'm looking for an app to encrypt files on my phone. I want the app to use a"watched folder ", automatically encrypting any file I save in there. The app should rename files to random filenames, provide its own file browser to show original filenames of course, and have NO Internet permissions so that I can trust that my local encrypted files couldn't get uploaded by a shady fake encryption app.
These seem commonsense criteria. What app do you use that meets them?

[Q] How to make Archos Gallery not display .hidden items?

On my other Android devices I can simply put a . in front of folders that I don't want the gallery to display (such as avatar pics and shortcut icons and what not) and it wouldn't. Then I could use eStrongs file manager or similar to browse to them when I needed them. I popped a 2GB MicroSD card I had laying around that already had some files on it from another Android device and ALL of the folders with images are showing up in the gallery... even those with a . in front of them.
Is there any way on an Archos 101 to set the Gallery to NOT display items inside of a '.' folder? Seems this is default with other Android devices so I'm hoping it's at least an option on these.
Ideas?
Thanks for the help.

Create a 0kb file called .nomedia. Place it in the folder of items you don't want shown. That should work.

Doesn't appear to work. I searched before posting this and found a few things about .nomedia and thought maybe you had to rename the actual folders w/the images within to .nomedia to hide them? Seems like this would be a PITA way to go about it.
Am I doing something wrong? Any other ideas?

It should work just fine. Did you name the file specifically .nomedia? No ext name. Did you reboot to see if that helps? Did you put the file in the folder of the items you don't want showing?
Here is some more specific instructions (I didn't write them):
1. On your computer, open Notepad or any other text editor
2. Save the blank file with the filename “.nomedia”, make sure that the Save as type is set as “All Files” instead of “Text documents”
3. Copy that file to the folder on your SD card containing picture files you don’t want to show up in the gallery. (Example: If you want to block aDyno image files from coming up, place the .nomedia file in the sdcard/aDyno folder)
4. Reboot your phone and hopefully the unwanted files should no longer be viewable.

Alright, w/more information I tried it again. I created a file just using a file browser on the device. This time around I created a file in Notepad on my PC called .nomedia and made sure the filetype was set to 'all files' before saving and that there was no extension (deleted the .txt) and then copied that file to my Archos 101. I first tried in the folder on the SD card that contained all the folders in question. I rebooted and it didn't seem to help. I then copied the file into each folder and rebooted. Still no dice. Whenever I open Gallery all the folders and images are still there. What am I doing wrong? Do I need to clear a cache or something or delete any tumbnails or ?? I'm sure I'm just doing something wrong but for the life of me I can't figure it out. I keep searching and am coming up with nothing. This was SO easier on my other Android devices as I just put a period in front of the name of the folders I didn't want to display and it was done. Simple as that. This is a royal PITA and I feel I'm not making any progress.

Do either of these allow you to simply hide w/o signing in or encryption? I found two other programs & both required this which I don't want to deal with. Just seems odd that others are saying this is working for them & I'm not having any luck. I don't mind installing an app as long as it works but I'm not sure why my Archos 101 would be different than the rest.

[Q] File permissions......permanent change?

I am trying to sync a rostering app between two devices using dropsync.
The .db files that need syncing are in the /data/data/com.blah.blah/databases directory. Using Root explorer I can change the permissions to give full rw permission to others. The two .db files will then upload to the dropsync server.
The problem is that whenever the app is opened and anything modified, the permissions change back to default and thus dropsync can't access the modified .db
Is there anyway to change this or am I wasting my time? what is the 'sticky' box option in RE?
I'm not sure precisely what "sticky" means, but it's not what you want--it doesn't involve persistence or "sticking".
You could try to make the files not owned by the app but set it so the group is the app. Make sure the group can read/write/execute, or whatever it needs. This way, the app can still use the file but won't be able to change its permissions.
Of course, it could see that it doesn't own the file and refuse to run. I'm not sure what sort of checks the program's authors implemented. This also won't work if the file is deleted and created anew--the new file would be owned by the app.
Yeah thanks for that,
I tried the ownership and group swap earlier, and am pretty sure the app re- writes the db.
Don't think is going to work.
cheers
Well its obvious that the app, when opened sets the permissions to the .db files so that they wont be usable by others. The way you describe the problem is more likely to be a file owner problem and not with the permissions. Try to set the app and the files to the same owner and see if that works. You could always make a script that would change the permissions/ownership of the file.
FYI,
The sticky bit is a special part of the permissions mask for a file or directory. When set on a directory, it tells the system to prevent anyone but a containing file's owner from deleting files in that directory. This is handy if you have a directory that's being used by multiple users on a system as scratch space as it prevents people from wiping out others' files.
For files....the behavior isn't defined.
Hope this helps,

[Q] How to delete default files

I hate those default Pics, music etc ASUS or whoever have put them and now I can't delete them from Filemanager...
How to delete any of the files I want ?
use root explorer to delete them. don't go deleting system/stock apps or your future OTA updates will fail.
I tried but says on those 17 default pics, "delete failed"...
BTW, why in file manager there is so bunch of stuff listed there, not organized... and you have no idea what is for what...
I tried FileManager HD - much better look/organization, also reports same error, failed to delete. Now in this app you can see next to file this: -rw
Are those files protected or something? pics and mp3's by default which I can't delete have that.
Thanks!
PS - Android -ICS, has folders listed totally wrong, you have system files listed with normal other folders which confuses normal people what is what and finding what they need to find. They should put ALL system files under 1 folder and make a tree of folders there and not in root put all folders there and leave up to us to manage in that bush
is your device rooted? and did you put it in read/write mode? otherwise it wont be able to delete the files
Sent from my Transformer Prime TF201 using XDA Premium HD app
You must set your file explorer to mount system files in read/write mode, by default they are set to read only. See in preferences menu.

[discussion] where does snapchat store photos/videos?

So I've went into the /data/data/com.snapchat.android/ folder, and it is only about 200KB, so the image/video files can't be stored there.
I also noticed if you have a new message, and you close and open the app, it will have to redownload it. So it seems that snapchat is storing the images in the RAM.
So I dumped the ram of my snapchat PID, using this method. I had to download a compiled gdb binary.
I then used photoRec to scan all the *.dump files [I concatenated them all first, the file was about 100MB]. For filesystem I said "Other."
All I got was one txt file. It seemed to be xml, and contained a lot of usernames of my friends, but that's all.
If anyone has any input on the subject, here is the thread for it!

Snapchat save picture under /data/data/com.snapchat.android/cache/received_image_snaps. You then have to copy and paste the file out of the folder, and rename the file extension from .jpgnomedia to .jpg
I can not find where the videos are stored. That's how I found this thread.
Like the previous poster said images are stored in /data/data/com.snapchat.android/cache/received_image_snaps. They are deleted when they are viewed though so you must copy them to your sdcard or wherever and change the file extension before viewing them. Videos are stored in /data/media/0/Android/data/com.snapchat.android/cache/tcs_pahn

I have not had time to check this location, however I have sort of discovered a workaround. [HTC Rezound CM10.1]
Ideally you should have a wifi toggle in the statusbar.
Open snapchat and then click on your snaps, after it loads the images [It will say "Loading image..", then "Tap to view"], turn off WiFi. Then you can view the snapchats [pic or video], and before enabling wifi, wipe Snapchat's data.
This way you can screenshot while offline and they will not know.
Alternatively you can use TitaniumBackup. Backup app while logged in, after viewing snapchat offline, restore data from backup so you do not constantly have to login.

If you can't find the video folder, it's because it deletes it and the videos when they are not loaded. They are stored under /data/media/Android/data/com.snapchat.android/cache/received_video_snaps/ in mp4 format with a .nomedia file extension. As soon as you navigate away from the app, they are deleted, so I set up a tasker gesture to allow me to copy them while they are loaded.
As people said before, the images are stored in /data/data/com.snapchat.android/cache/received_image_snaps/ with the jpg.nomedia extension. If that folder doesn't exist, try making sure you've received and loaded a snapchat first. The images seem to stay until they're viewed.

That location you name for videos doesn't exist on my phone.
- I have /data/media/ "0" and "obb" are the only 2 folders within there
- I have also read that the videos are stored in /Storage (SD CARD)/Android/data/com.snapchat.android/cache/... but there isn't anything further from here, my 'cache' folder is empty, there's never been a "received_video_snaps" folder, let alone any content within here.
- I am able to get the photos from /data/data/com.snapchat.android/cache/received_image_snaps/ but never been able to intercept videos
Note: this is all done BEFORE "viewing" the material and allowing it to "load" and show "tap to view" from within SC

I'm running TouchWiz. I wonder if you are on a 4.2.2 ROM or something, cause I've experienced the sdcard being moved around before...
Does your "0" folder have any subdirectories? such as Android/data/com.snapchat.android/cache/
In any case, videos are special: You need to actually click "load" (but don't hold, or else you'll actually view it before saving) if it doesn't do that automatically. Unless I misinterpreted, you didn't do that step. I think they might load automatically on Wi-Fi or something, though. For a general rule: As soon as it says "Load", the video is no longer (or never was) on your device. Furthermore, the sneaky little application deletes the folder at the same time, which is why you're never seeing "received_video_snaps" within the cache folder you found (assuming that one actually stores the videos in your version) because in my experience, almost everytime you navigate away from Snapchat, it unloads the video.
If you want to test for whether a file exists in a particular directory using Tasker, mess around with different directories in a File Modified profile (and have the associated task flash something). It'll flash as soon as something is added to that folder (including another folder, it seems).
Otherwise, check out my thread for this here.
I'm not familiar with Tasker. is it possible to have it automagically copy and rename the files that show up in the picture cache folder upon receiving a snap?
-edit-
From reddit:
I've got one method working on doing this, albeit I dislike it because this is questionable practice as is.
you''ll need Tasker and the Secure Settings plugin (tasker's run shell didn't like playing nice most of the time, but the secure setting run command does).
so i have tasker wait for snapchat to be opened, then the opening tasks are to wait 7 seconds (gives you time to load any pictures, honestly, i tried doing this with a file closed but tasker doesn't seem to like using wildcards in that command. if you really want, you can make this an exit command and open snapchat then back out before viewing)
then run shell as root cp -r /data/data/com.snapchat.android/cache/received_image_snaps/ /storage/emulated/0/snaps/ (you'll need to change the second directory, mine is for a gnex on 4.2.2 so that's why it's emulated/0)
next, you'll need to make a script in atext editor, and for sake of sanity, push it to /system/bin with chmod 755 (rwxr-xr-x)
the script then reads as CODE
!/system/bin/sh #there should be a hashtag in front of this but reddit's formatting is being wonky
cd /storage/emulated/0/snaps/ #wherever you copied them to
for file in *.nomedia
do
mv "$file" "${file/.nomedia}"
done
exit
then in tasker, as an exit action, run a secure settings run command with the command of whatever your script name is (include location if you do no push to bin).
it should work
You can play with the triggers and such, but i was having no luck including the scripted portion with the copy actions, it never seemed to run the script (secure settings has options to notify that it's running/completed).
Again, this is mean to be instructional on how to automate this with tasker, since I wanted to solve a puzzle. Not for anyone to be a creepy ass person saving snapchats that you shouldn't.

Deleted images are deleted. That's the point of Snapchat. As for the file you moved (I'd recommend you copy it instead, cause Snapchat'll show a blank screen when you view it if you moved the file), make sure it ends in .jpg (for images) or .mp4 (for videos).

Actually there is a program called PhotoRec that scans a disk for files using the headers. So as long as the file is unfragmented and not been written over, you can retrieve it with the software. Of course you'll have to either plug in your phone to your PC with usb mass storage mode [if your phone supports it], or else put it in a card reader.

Well actually it's not run from the phone [as I mentioned in my previous post], you must plug your card into your PC with usb mode in order for it to work.
I have used PhotoRec in the past and it has worked pretty well. The only thing, and it's not PhotoRec's fault, your files will have a random number. There's no way to know what the old filename/path used to be, so you have to figure that part out on your own.
In short, always backup your sdcard unless you don't mind losing everything, and depending on the damage, might be able to recover the files, but only the ones not fragmented and they will be randomly named.
I developed an easy way to sync the received pictures and videos with your Dropbox account.

Samsung Voice Note

Hello,
I have a bunch of voice recordings that are in my sounds folder, (m4a and 3ga files) when using the Samsung Voice Note App. If I record a new one it shows up but once I move them between sound folders (internal or external) they dont show up within the app anymore. Is there a way to refresh or should I be using Root Explorer to push them somehow? I tried using the stock file manager app and Astro. Almost like its not refreshing...
Any help appreciated

Hello,
When you're copying it to the External Storage, where are you copying them to? Is there a file called ".nomedia" in the folder where these items are located (or in a high-level folder)? If that ".nomedia" file is present, apps won't notice anything in that folder (or it's subfolders) when they scan for media. This prevents apps like gallery from seeing the various thumbnails that are throughout the storage.
If you don't see them in your file explorer, you may need to turn on "Show Hidden Files" in the settings.
Hope this helps!

I've never had issues deleting .nomedia files... Does your root explorer actually have root access?
Where are you trying to copy these files? Maybe you can create a new folder (sans .nomedia file) and stick them in there. Just remember, if there are any "parent" folders that have the .nomedia in them, it won't search the subfolders for media.

Your the man! Root explorer wouldn't delete it and I kept getting this message View attachment 2784852
so then I ended up deleting it from the stock file manager and it worked. I would of never figured that out without your help. I kept seeing the. nomedia. file but ignored it. I don't even know where it came from, just glad that worked.
