File Storage Emulated 0 [BEST] Download Bluetooth_content_share-1.html



On my Samsung devices I put a file in the /Download folder. When I select the file within my app (via a file browser), the file is called /storage/emulated/0/Download/myfile.db. This name is stored in my app settings.

You can't use the Download as an guaranteed storage place for your files. You should use the Internal storage for the app. This is what Google has written about the download folder:


Caution: The external storage might become unavailable if the user removes the SD card or connects the device to a computer. And the files are still visible to the user and other apps that have the READ_EXTERNAL_STORAGE permission. So if your app's functionality depends on these files or you need to completely restrict access, you should instead write your files to the internal storage.


Bluetooth File Transfer offers an efficient way to exchange files from one Android device to another and browse the contents of virtually any Bluetooth enabled device. Users may easily select a file from their device and send it to a device of their choosing, or find the specific file on another device and download it. The ease of use and great user interface make this a phenomenal application.


Bluetooth File Transfer is a mere 2.9MB, making it an incredibly light and quick application that downloads within seconds. On startup users are greeted by a friendly user interface featuring a modern dark background with sharp white text that is easy to read. Intuitive functions are easy to figure out and no instructions are needed. The screen resembles a basic file folder setup. On the first tab the user can browse their own file structure and select files that they wish to share. On the second tab the user can manage their Bluetooth connections and browse the file structure of selected devices. This app also adds another level of security to your Bluetooth connections by requiring authentication on all incoming connections. Favorite and trusted connections can be saved for faster file transfers in the future.


Android supports a variety of storage device types, the major ones being portable storage and emulated storage. While portable storage can be provided by media such as a USB or SD card, emulated storage is added to an Android device by allowing the exposure of the internal storage through an emulation layer.


So why does emulation exist? Providing an abstraction layer or emulation on the original file system allows the restriction of unauthorized access of third-party applications and systems to the private media of the user and other data lying on physical storages such as SD cards. This translates to the fact that emulation renders your actual file system only traversable and not readable or writable by third-party apps/processes depending on the permissions.


Emulation can exist in both internal and external storage; therefore, in order to distinguish between the two, Android may use 0 and 1 to depict the file directory of the item, whether it lies in the internal storage or the external storage such as an SD card.


Plug in your device to your desktop and run adb shell; since Android does not permit reading /storage/emulated/0/, you can go to its subdirectory. Since you are in your command shell (by running adb shell), you can go to cd/storage/emulated/0 and be able to look around.


Suppose you have an app that looks into a specific file or folder to search for an item of one category such as videos or music; it may look into the /storage/emulated/0/XYZ (XYZ being any sub-directory) for the same. For example, if you have Poweramp to look for music in /storage/emulated/0/Downloads folder, and if you have no music in the same folder, it will show /storage/emulated/0/Downloads as missing or unreadable.


Your app may look into this sub-directory for music for two reasons: firstly, it has been set to a default music repository in your settings, or Poweramp previously found music in the directory, which is now wiped. Now, in order to solve this, all you have to do is put some music in /storage/emulated/0/Downloads folder so Poweramp can look play for this directory, or go to Settings>Poweramp>Library>Downloads and untick Downloads as a directory where the application will look for music.


به عبارتی دیگر emulated storage یا فضای ذخیره سازی شبیه سازی شده یکی از راهکارهای اندروید برای بهبود امنیت و حفظ حریم خصوصی کاربران است.
