如何访问 /storage/emulated/0/

Question

I have written a code to record audio and save it to below file location.

private String getFilename() {
    String filepath = Environment.getExternalStorageDirectory().getPath();
    File file = new File(filepath, AUDIO_RECORDER_FOLDER);
    if (!file.exists()) {
        file.mkdirs();
    }
    return (file.getAbsolutePath() + "/" + System.currentTimeMillis() + file_exts[currentFormat]);
}

In Logcat, it gives me a file location as

/storage/emulated/0/AudioRecorder/1436854479696.mp4

I am not able to find this file location on my SD card. How to access the location?

Answer 1

No need for third party apps

My Android 6.0 allows me to browse the intern memory without the need for third party apps. I simply do this*:

1. "Settings"
2. "Storage and USB"
3. "Intern"
4. [let it load a bit...]
5. [scroll all the way down]
6. "Browse"

* Words may not correspond to the standard English version ones, since I'm just freely translating them from Portuguese.

Note : At least in my phone, /storage/emulated/0 does not correspond to SD card, but to intern memory . This method did not work for my external card, but I never tried it with another phone.

Hope this helps!

Also you can use Android Debug Bridge (adb) to copy your file from Android device to folder on your PC:

adb pull /storage/emulated/0/AudioRecorder/1436854479696.mp4 <folder_on_your_PC_e.g. c:/temp>

And you can copy from device whole AudioRecorder folder:

adb pull /storage/emulated/0/AudioRecorder <folder_on_your_PC_e.g. c:/temp>

Answer 3

As Hiren stated, you'll need a file explorer to see your directory. If you're rooted I highly suggest root explorer, otherwise ES File Explorer is a good choice.

Answer 4

Plug in your device and run adb shell which will get you a command shell on your device. You don't have permission to read /storage/emulated/ but since you know it's in subdirectory 0 just go cd /storage/emulated/0 and you will be able to look around and interact as aspected.

Note: you can use adb wirelessly as well

Answer 5

Try This

private String getFilename() {
    String filepath = Environment.getExternalStorageDirectory().getPath();
    File file = new File(filepath + "/AudioRecorder" );
    if (!file.exists()) {
        file.mkdirs();
    }
    return (file.getAbsolutePath() + "/" + System.currentTimeMillis() + ".mp4");
}

Answer 6

In Emulator, to view this file click on Settings>Storage>Other>Android>data>com.companyname.textapp>file>Download. Here, textapp is the name of the app you are working on.

Mr Expensive Toys said: Am amazed that this problem is still showing up as it started happening as far back as Honeycomb.

So, the /storage/emulated/0/DCIM/Camera is the same folder as your normal DCIM/Camera folder. Its just a symlink. So the files are actually in the right location you just have an app that put bad data into the MediaStore Database.

When accessing files from your PC your are actually enumerating the MediaStorage database for files. Its not pulling a traditional directory lists. So what you see is based on what is in that database and the path entries in the database. Files in the database pointing to emulated directories aren't shown as they are assumed to be duplicates as its the same physical directory as your normal DCIM/Camera. What is going on is that some poorly written third party apps are inserting entries into the database with the /storage/emulated/0/DCIM/Camera path instead of the proper root path to DCIM/Camera. Which means that the MTP service can't see them when you are hooked up to your PC.

Usually the easiest way to fix the problem is to just clear the MediaStore databases to get the bad entries out of the MediaStore Database and let the system reindex the files and put into the database with the proper paths.

Settings->apps Hit 3 dot menu in top right and select Show System Find Media Storage, Select it, Select Storage, then Clear Data Find External Storage, Select it , Select Storage, then Clear Data Turn phone off, turn phone back on, wait for indexer service to rebuild the data.

When you are done the files should show up with proper directory tree and be visible from the PC. Depending on amount of files on the phone it can take as 10-20 minutes to rebuild the media database as the service walks the phone directories, getting meta data, creating thumbnails, etc.

在这里，它位于 /mnt/shell/emulated/0

Answer 9

Android recommends that you call Environment.getExternalStorageDirectory.getPath() instead of hardcoding /sdcard/ in path name. This returns the primary shared/external storage directory. So, if storage is emulated, this will return /storage/emulated/0 . If you explore the device storage with a file explorer, the said directory will be /mnt/sdcard (confirmed on Xperia Z2 running Android 6).

Answer 10

Try it from

ftp://ip_my_s5:2221/mnt/sdcard/Pictures/Screenshots

which point onto /storage/emulated/0

Answer 11

In my case, /storage/emulated/0/ corresponds to my device's root path . For example, when i take a photo with my phone's default camera application, the images are saved automatically /store/emulated/0/DCIM/Camera/mypicname.jpeg

For example, suppose that you want to store your pictures in /Pictures directory, namely in Pictures directory which exist in root directory. So you use the below code.

File storageDir = Environment.getExternalStoragePublicDirectory( Environment.DIRECTORY_PICTURES );

If you want to save the images in DCIM or Downloads directory, give the below arguments to the Environment.getExternalStoragePublicDirectory() method shown above.

Environment.DIRECTORY_DCIM
Environment.DIRECTORY_Downloads

Then specify your image name :

String imageFileName = "JPEG_" + timeStamp + "_";

Then create the file object as shown below. You specify the suffix as the 2nd argument.

File image = File.createTempFile(
            imageFileName,  // prefix
            ".jpg",         // suffix
            storageDir      // directory
);

Answer 12

If you are using a simulator in Android Studio on Mac you can go to View -> Tool Windows -> Device File Explorer . Here you can use a finder-like structure.

Answer 13

if you are using Android device monitor and android emulator : I have accessed following way: Data/Media/0/

Answer 14

To RESTORE your pictures from /storage/emulated/0/ simply open the 100Andro file..there you will see your pictures although you may not have access to them in you pc explorer. There open each picture one by one, go on setting (three dots..) and save the picture. It will show up in the android file 'Pictures' from where you can also copy them by using your explorer. There is no 'save all' function, however so it must be done one by one, but it works.

for Xamarin Android

Using command //get the file directory
