I want to create a folder in Internal storage root but NOT IN data/data.
In my favorite path, except data/data, that user can see that in File Manager. What should I do?
I try many things like this:
String path = "my folder"+File.separator+"gallery";
File directory = new File(path);
File mydir = context.getDir("mydir", Context.MODE_PRIVATE); //Creating an internal dir;
File fileWithinMyDir = new File(mydir, "myfile"); //Getting a file within the dir.
FileOutputStream out = new FileOutputStream(fileWithinMyDir); //Use the stream as usual to write into the file
Try using the above code

I am working on an application where i need to create folder in the internal storage (phone memory) when the SD card is also available. I am using the Environment.getExternalStorageDirectory().toString()+"/"+folderName; when i run this widout SD card it create folder in Internal but after inserting SD card when i run the same it create folder on SD card. But i want to create folder in Internal Storage.
Here is my Code
private static File contactsFile;
private static String contacts_storage_path;
contacts_storage_path = Environment.getExternalStorageDirectory().toString()+"/"+folderName;
contactsFile = new File(contacts_storage_path);
if (!contactsFile.exists())
{
//contactsFile.createNewFile();
contactsFile.mkdirs();
}
filecontact=new File(contactsFile, contact_file_name);
It is important to use Context.getDir(String value, int mode) to create directory in internal storage.
Refer below code -
File mydir = context.getDir("mydir", Context.MODE_PRIVATE); //Creating an internal dir;
File fileWithinMyDir = new File(mydir, "myfile"); //Getting a file within the dir.
FileOutputStream out = new FileOutputStream(fileWithinMyDir); //Use the stream as usual to write into the file.
Cheers :)
You can create a folder in Internal memory like this:
File dir = context.getDir("dir", Context.MODE_PRIVATE);
dir.mkdirs();
FileOutputStream outStream = null;
**File sdCard = Environment.getExternalStorageDirectory();**
**File dir = new File(sdCard.getAbsolutePath() + "/YourFolderName");**
dir.mkdirs();
//to know the path
Log.d(TAG, dir.getAbsolutePath();
String fileName = String.format("%d.jpg", System.currentTimeMillis());
File outFile = new File(dir, fileName);
outStream = new FileOutputStream(outFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
outStream.flush();
outStream.close();
Hope this helps!
I create a folder called "res" inside sdcard
File f = new File(Environment.getExternalStorageDirectory() + "/res/");
f.mkdirs();
The folder is successfully created.
But when I try to create a file within the folder does not work.
String string = "hello!";
File file = new File(Environment.getExternalStorageDirectory() + "/res/","test.txt");
FileOutputStream fos = new FileOutputStream(file);
fos.write(string.getBytes());
fos.close();
LOGCAT
java.io.FileNotFoundException: /mnt/sdcard/res/test.txt (Not a directory)
The call to new File() doesn't actually create the file. You need to check if the file exists by using file.exists(). If it doesn't, you must create the file by calling file.createNewFile(). See this answer for sample code: https://stackoverflow.com/a/7012122/379245
I may be way off here, but I am trying to download a file and store it in the downloads folder on my phone. I am getting a "java.io.FileNotFoundException" error, because the file doesn't exist, because I'm trying to download it...what am I doing wrong?
String PATH = Environment.getExternalStorageDirectory() + "/download/";
File dir = new File(PATH);
dir.mkdirs();
File outputFile = new File(dir, "downloadFile");
FileOutputStream fos = new FileOutputStream(outputFile);
This fails, with the following:
java.io.FileNotFoundException: /mnt/sdcard/download/downloadFile (Permission denied)
I am using the WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE permissions....
Please try following updated code,
String PATH = Environment.getExternalStorageDirectory() + "/download";
File dir = new File(PATH);
dir.mkdirs();
File outputFile = new File(dir, "downloadFile");
if ( !outputFile.exists() )
{
outputFile.create();
}
FileOutputStream fos = new FileOutputStream(outputFile);
There is a "/" after the download. This way Android is thinking that you are creating Recursive Directory. While using mkdirs(), you can not create recursive directories.
You can also check my answer for same in Java ME here.
Add Permission to write external memory in your Manifest file.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
Here you want to make directoy?
it there is already folder of download than use this code directly.
// create a File object for the parent directory
File Directory = new File("/sdcard/download/");
Directory.mkdirs();
// create a File object for the output file
File outputFile = new File(Directory, downloadFile);
// now attach the OutputStream to the file object, instead of a String representation
FileOutputStream fos = new FileOutputStream(outputFile);
It might be wise to use Environment.getExternalStorageDirectory() for getting the "SD Card" directory as this might change
I want to make a folder in the Internal Memory in my application to store Audio Files,then check if the exist to do some operations.
How to make this folde, in which path, and how to retrieve these files again?
File mydir = context.getDir("mydir", Context.MODE_PRIVATE); //Creating an internal dir;
File fileWithinMyDir = new File(mydir, "myfile"); //Getting a file within the dir.
FileOutputStream out = new FileOutputStream(fileWithinMyDir); //Use the stream as usual to write into the file
For deleting a file from internal :
if (new File("path/to/file").delete()) {
// Deleted
} else {
// Not deleted
}
I have a little issue with creating folders for my application in Internal Memory. I'm using this piece of code :
public static void createFoldersInInternalStorage(Context context){
try {
File usersFolder = context.getDir("users", Context.MODE_PRIVATE);
File fileWithinMyDir = new File(usersFolder, "users.txt"); //Getting a file within the dir.
FileOutputStream out = new FileOutputStream(fileWithinMyDir); //Use the stream as usual to write into the file.
File dataFolder = context.getDir("data", Context.MODE_PRIVATE);
File fileWithinMyDir2 = new File(dataFolder, "data.txt"); //Getting a file within the dir.
FileOutputStream out2 = new FileOutputStream(fileWithinMyDir2); //Use the stream as usual to write into the file.
File publicFolder = context.getDir("public", Context.MODE_PRIVATE);
File fileWithinMyDir3 = new File(publicFolder, "public.txt"); //Getting a file within the dir.
FileOutputStream out3 = new FileOutputStream(fileWithinMyDir3); //Use the stream as usual to write into the file.
} catch(FileNotFoundException e){
e.printStackTrace();
}
}
So folders are created but in front of their name there is the beginning "app_" : app_users, app_data, app_public. Is there a way to create the folders with the name given by me? And another question : I want to first create folder Documents and than all other folders "Data, Public, Users" on it.... And the last question : How can I give the right folder path if I wanted to create a file in Documents/Users/myfile.txt in Internal Memory?
Thanks in advance!
You can use this :
File myDir = context.getFilesDir();
String filename = "documents/users/userId/imagename.png";
File file = new File(myDir, filename);
file.createNewFile();
file.mkdirs();
FileOutputStream fos = new FileOutputStream(file);
fos.write(mediaCardBuffer);
fos.flush();
fos.close();
Is there a way to create the folders with the name given by me?
Use getFilesDir() and Java file I/O instead of getDir().
How can I give the right folder path if I wanted to create a file in Documents/Users/myfile.txt in Internal Memory?
Use getFilesDir() and Java file I/O, such as the File constructor that takes a File and a String to assemble a path.
