I want to hide some info (encryption keys) in a private area. I know there are a lot of threads on the topic and from what i can tell - it basically comes down to - there's no security just kidding. It seems like the data you have in your private area /data/data/com.company.product/files is only accessible to your application, so it would be sufficient to store anything (like encryption keys for example) in just plain text files there if you wanted. the big drawback of doing this though is that a "rooted" phone would be able to access that area -- therefore, no security. does "copy protection" solve this problem? if I "copy protect" my .apk bundle, I know that that makes it so that it cannot be seen by "rooted" phones in the Android Market, but what about if the .apk bundle got out in the wild (i.e. posted on some website, not via market). Would a "rooted" phone then be able to grab and install the .apk file (and ultimately gain access to the app-private area)? Could someone install the copy protected .apk file in an emulator?
I'm trying to unbundle a binary file (sound1.ogg) and store it on the sdcard.So it starts out as a raw resource (R.raw.sound1) and should end up as a copy named /sdcard/ mydir/sound1.ogg I wrote a method called something like copyResourceToFile() and did a copy via file descriptors / streams. But the target file just isn't right.If I do a buffered read, the target file ends up being WAY bigger - like 10x bigger.If I just do a byte-by-byte read for the size of the original file, the target file is the right size but is not the same file. Is there a simpler (well, correct/working) way to do this thing?
I'm trying to transfer a 5gb file onto my Eris. The SD card is mounted, and it shows that 7gb is free. I am able to copy over a 1gb file to and from, but when I try the 5gb file, I receive the following message:The disk in the destination drive is full. Insert a new disk to continue. Retry Cancel.If I click Retry, I get the following: Cannot copy (filename): there is not enough free disk space. What's the deal? Anyone know how to get this to work?
When I install it, are there files Android saved on my old microSD card I need to copy to my computer and transfer to the new card? It seems like most files are saved to the SD card rather than the internal memory for my apps and don't want to cause any issues when I put the new one in.
I am using the ES File Explorer on my HTC One M8, but it doesn't allow me to copy pictures on my SD card. Root Explorer also not. Is it because of Kitkat? Are there any other file browsers that allow copying stuff to the SD card?
When making an image I accidentally had Clockworkmod image be saved to the device itself instead of being saved to the external SD card.
I am able to browse to it using Root Explorer and select to Copy it, but how do I PASTE it onto the external SD card when Root Explorer only accesses the device directory and not the external SD card?
Quick 2nd question: I know on some previous devices such as the Galaxy S 4G you were *not* supposed to run Clockworkmod after booting in and from the Apps Drawer, instead you were only supposed to run directly from the startup screen before booting in. Is it OK to actually start the Clockwork Backup/Restore process from the Apps Drawer of the Galaxy S4 and let it reboot and do its thing or is it only supposed to be run BEFORE booting in?
i am working n audio recording. i can store the file using file.getAbosolutPath() mehtod. it stores the file in path: /data/data/com.example.audio_demo/files/output.amr i wann store that in SDCARD.iso and how retrive that and play.
I have an SQL lite database that I am trying to copy to the device. I was able to copy it to the emulator easily using DDMS however with the protection in the device, I cannot access the database files from the DDMS perspective.
I read many attempts here but couldn't find an easy solution.
Is there any way to attach the database (let's say named 'proj') and replace the currently created database proj in he device files?
I have some information generated in the Android Emulator, and the only way I can see to get it out is using the Log class.
However, you cannot copy-and-paste from the DDMS log window. This is really annoying as I cannot use the information in another application, for example, without retyping it.
Is there a better way to get debug information out of the emulator? What happens when you write more complex applications? What do you do when you need to verify it is writing correct information to URLs, databases, files etc?
My question is how to copy a file from sdcard to /data/misc/wifi directory? I am working on a configuration tool for wiki supporting wpa enterprise. The configured file wpa_supplicant.conf must be put in / data/misc/wifi in order to work. So how can I move the file from sdcard to there? Is there any function calls to request a superuser access?
Everything works great other than the touchpad function. When I try to move the mouse it just doesn't move! When I use the trackball to move up and down my internet browser scrolls up and down the page and when I click it will click on links so that's all good. It's just the mouse won't move. I have a USB mouse attached to my PC and I have followed all of the FAQ's on the gMote website. It only seems to work in debug mode. Any answers to why that might be? Is there an application that will allow you to copy your texts to your SIM card?
If I upgrade my SD card from say 8 to 16 gigs... can I merely copy over the directories from my old card to my new one so that my apps still work the same? Are there any hidden files or directories I need to worry about?
I need to copy files to the system partition of the emulator. As it is read only by default, I use the command "adb remount" to have write permissions and I can then copy the files.
My problem is that when I close the emulator and that I restart it, the copied files were missing. It's very annoying because I must write file permissions that are read at startup of the emulator (platform.xml file in /system/etc/permissions)
I am trying to create a folder and several subdirectory within it on the SD Card... I then want to transfer files that I have stored in /res/raw to that folder... I addition, I want this to only happen once, the first time the program is ever run. I realize that this is ridiculously open-ended, and that I am asking a lot...
I have an paid app currently selling in the market with its copy protection turned on. I'm thinking about turning this off in order to reduce the size of my app and allow the "move to sd card" function to work. I've read that, in the past, people were having issues when the dev switched the copy protection setting from off to on. Is this still an issue? If users are still having problems then I'll leave things as they are. I understand that copy protection isn't really helping and I should just leave it off, but since I've had it on through several updates now, I'd hate to cause my users grief by changing now.
How come this is the only file manager on the market (that I've found... I went through quite a few) that can open an HTML file from your SD card? I was a loyal user of Estrogen until I found that it couldn't.
