So I want to make a folder right in the main part of my internal storage. So basically the same area that you see when you plug your phone in your computer and you open up internal storage and see all those folders and files.
I've tried the following codes:
String path = Environment.getDataDirectory().getAbsolutePath().toString()+ "/storage/emulated/0/appFolder";
File mFolder = new File(path);
if (!mFolder.exists()) {
mFolder.mkdir();
}
Along with
ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext());
File myDir = contextWrapper.getFilesDir();
// Documents Path
String documents = "appFolder";
File documentsFolder = new File(myDir, documents);
documentsFolder.mkdirs(); // this line creates data folder at documents directory
Along with a few others I've found online, but none of these seem to make a folder or at least on the internal storage that I want.
I'm not sure if I'm missing something? But any help would be great, I've tried essentially copying a lot of posts I've seen online but none has even gotten me a folder? I don't get any errors either?
I have:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.app.name.app">
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
in my manifest, although I think I'm using gradle if that helps
-------------edit
Unfortunately I tried this from the url aswell, but still no folder.
ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext());
File mydir = contextWrapper.getDir("mydir", Context.MODE_PRIVATE); //Creating an internal dir;
Okay somehow fixed the problem
Turns out if you do
File Directory = new File("/sdcard/folderName/");
// have the object build the directory structure, if needed.
Directory.mkdirs();
and use
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
</manifest>
it now works.
I'm not too sure if changing the permission from INTERNAL to EXTERNAL did it, or if it was the directory which is now just /sdcard/folder/or probably both, but either way it worked so I'm happy. Thanks all!!

I'm new at this.
Telegram, Whatsapp, Vk, Aliexpress - All this apps can write they folders in /Storage/emulated/0
How can I create my folder in this place for Android 5...10?
When I try to use File("/storage/emulated/0/", myfile) - it doesn't work.
Please, can anyone give some mini example how can I create my files in storage
Since you haven't written any code, I can't tell you what you're doing wrong. But this is something that might help you.
First you need to declare permissions on your manifest.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
After that you can simply use this to create your folder.
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/" +
"folderName";
File directory = new File(path);
directory.mkdirs(); // It returns a boolean you can use it to check if your folder
// was created.
Yes, You can create Folders inside the External Storage too.
But, keep in mind that you cannot use emulated/0 because it is different for different devices.
File path = new
File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Folder/");
if(!path.exists()){
boolean k = path.mkdirs();
}
Although, Environment.getExternalStorageDirectory() is deprecated as of API29. So You can use getExternalDir() too.
Good Morning,
I am trying to create file directory to external storage by using below code:
File noteDirectory = new File(Environment.getExternalStorageDirectory()+"/Notes");
noteDirectory.mkdirs()
My question is what happens if noteDirectory already exists on user's device?
Nothing happens, other than mkdirs() will return false. It will not crash with an error or anything like that.
BTW, please replace:
File noteDirectory = new File(Environment.getExternalStorageDirectory()+"/Notes");
with:
File noteDirectory = new File(Environment.getExternalStorageDirectory(), "Notes");
I'm developping an application where I need to create new folders/files in the sdcard. The thing is I can see them using a root explorer but not with the default one which comes with Android.
I've taken a look at several similar questions here but don't seem to work for me.
For sure, I'm using in my manifest this:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
and I'm writing all the Files using:
String path = Environment.getExternalStorageDirectory() + "/FolderName/FileName.format"
but as I said, these new folders/files remained hidden and can only be seen using a root explorer. Neither the folder nor file name starts with "."
Thanks in advance.
Try using mkDirs()
File dir = new File(fullPath);
if (!dir.exists()) {
dir.mkdirs();
}
I am in need to create a text file where the input is taken from the user.
I am trying to save the txt file in a folder(folder should be created even if it is not there)
My code is as follows,
FileOutputStream fileos = null;
if (FreeMemory() != 0) {
FileOutputStream fos=null;
try {
File path=new File(getFilesDir(),"sri");
if(!path.exists()){
path.mkdir();
}
File mypath=new File(path,"myfile.txt");
if (!mypath.exists()) {
fos = new FileOutputStream( mypath);
String text="Write Hii";
fos.write(text.getBytes());
fos.close();
}
}catch(Exception e){
}
}
The "path" variable gives this path: "/data/data/com.example.gm/files/sri"
I navigated to this path in my device: Android-->Data-->com.example.gm-->files-->
but the folder "sri" is not created and even the file also. Am I navigating to th ecorrect path ? I am not able to find out the file in the device.
I searched for the folder by installing "Astro File Manager" app too. But, couldn't find it. I am not getting any Exception when writing to the folder. The code must be correct. But where is the folder and file? Please anyone help me in solving this.
I want to save the txt file in internal memory of my device.
Whats wrong with my code? Please suggest me the solution.
I have gone through many trails and finally approached stackoverflow.
Thanks for any help!!
The data in the internal storage is not accessible out side the application owning it, so any third party application like file browser or Astro File Manager will not be able to see the files. The application with root access will only be able to access the files in the internal memory. I believe you should programmatically verify if the file is created. getFilesDir() will give the internal memory location allocated to that app.
Have you give the permission in manifiest file
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
I have a routed device and when I do this
adb shell cat /data/misc/bluetooth/dynamic_auto_pairing.conf
it prints the content of this file.
But in my code when I write something like this, it says that the file does not exist. Well from the console I see it I know is there, but from code I can't read it. My question is what is the problem , am I missing some permission or what is the problem ? can someone provide me with some code to read the content from this file.
Thanks
File pa = new File("/data/misc/bluetooth/","dynamic_auto_pairing.conf");
//this doesn't works also
//File pa = new File("/data/misc/bluetooth","dynamic_auto_pairing.conf");
//File pa = new File("/data/misc/bluetooth/dynamic_auto_pairing.conf");
if(pa.exists()){
Log.v("tag", "does exists");
}else{
Log.v("tag", "does NOT exist");
}
If the file is on sdcard, try:
File pa = new File(Environment.getExternalStorageDirectory() + "/data/misc/bluetooth/dynamic_auto_pairing.conf");
Also try to add:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
outside <application></application> in your manifest file.
EDIT
If the file is in internal memory: Your app can read only from a special folder in internal memory. The path to that folder is returned by:
getFilesDir().getAbsolutePath()
So put the file there and read it with openFileInput().
More info:
http://developer.android.com/guide/topics/data/data-storage.html#filesInternal
From the docs for File...
public File (String dirPath, String name)
Constructs a new File using the specified directory path and file name, placing a path separator between the two.
In your code you are using...
File pa = new File("/data/misc/bluetooth/","dynamic_auto_pairing.conf");
...and because your dirPath ends with a separator "/data/misc/bluetooth/" it will result in two separators. In other words, effective path will be...
/data/misc/bluetooth//dynamic_auto_pairing.conf
Note the // after 'bluetooth`
If you are using android 6.0 or higher. You must request permission in code.
