I take DOCUMENT_TREE uri read permission, and i have to copy its video to other folder, so after all we find that if i can get actual path then i can copy that file to other Folder,some methods of get path shows Error No such directory, but finally a method shows access denied that folder.
so basically two question here generated
is READ_EXTERNAL_STORAGE have to use, to that specific folder,do Play console reject my app to use READ_EXTERNAL_STORAGE in my status saver application??
how can take that specific folder permission with DOCUMENT_TREE to not show that folder access denied??

I have taken this Folder Persistable URI_READ_PERMISSION
and now want to read directory which is inside it
want to read this Folder videos/images
trying in java
pls
I am taking permission of scope storage through Intent with DOCUMENT_TREE, where, in intent we set initial uri to Android, media folder, and set functionality that if permission of that folder not granted, show again Permission fragment, where we ask again permission
but, at that time we click on button to open DOCUMENT_TREE Intent, it doesn't show Android/media folder directly, it shows another folder, which folder (eg we granted com.telegram folder) , then it shows telegram folder directly to grant permission.
so where is the problem, and how we can solve?? so it open only given uri folder every time??

While working to upgrade to API 33 from API 28 I can no longer access the files that I have created with ACTION_CREATE_DOCUMENT intent without using its URI.
I have tried making sure to ensure READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permissions were taken before attempting to access the file. I manage to create the file but when creating its path and trying to access it at that path the app suddenly fails to open it even though it should be the owner of that file if I'm not wrong?
I absolutely cannot use MANAGE_EXTERNAL_STORAGE permission because that doesn't fit the usecase that I have.
Is there a way to use the path instead of the URI returned to write to the file? the file extension is csv.
I have created a sample to write and read the file.
Create the File:
Intent intent = new Intent(Intent.ActionCreateDocument);
intent.AddCategory(Intent.CategoryOpenable);
intent.SetType("application/txt");
intent.PutExtra(Intent.ExtraTitle, "anew.txt");
StartActivity(intent);
Then I saved the file into the Download Folder by the system file manager and write the file.
File.WriteAllText("/storage/emulated/0/Download/anew.txt", "this is file content");
Every thing worked well after I granted the storage permission to my app. But when I saved the file in the Documents Folder, I will get the error about accessing path /storage/emulated/0/Documents/anew.txt is denied.
The read and write storage permission cann't access the Documentss Folder with a path.
I want to store data recorded with the accelerometer on the external storage but I have an error when I try to create the directory in which I want to save the data. My code is as follows :
dataDirectory=Environment.getDataDirectory();
path=DataDirectory.getAbsolutePath();
path+="/"+getResources().getString(R.string.DirectoryName);
myDirectory=new File(path);
myDirectory.createNewFile();
The createNewFile call triggers an IOException.
I can add two things : the path variable is set to "/data" after the call to getAbsolutePath and the getExternalStorageState function returns "mounted".
Can anyone tell me what is wrong in my code?
Thanks in advance for the time you will spend trying to help me.
You can't have permission to write in the /data directory
Use the sdcard directory
Or try working in the /data/data/com.yourapplication/files directory where you do have permission. Use Context.getFilesDir() to get the path of your application's working directory.
try this
path=DataDirectory.getAbsolutePath().toString();
add WRITE_EXTERNAL_STORAGE permission in your manifest file
I am getting this error on runtime, when trying to run my GWT application:
java.security.AccessControlException: access denied (java.io.FilePermission C:\Users\Admin\AppData\Local\Temp\tmp-andami read)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)
(Stack trace is longer, but I guess that this is enough to focus the problem source)
I have searched in Google about this issue and what I have found is, in general terms, to change permissions on java.policy file (located in C:\Program Files\Java\jre6\lib\security), so I did things like:
permission java.io.FilePermission "<<ALL FILES>>" , "read";
permission java.io.FilePermission "C:\Users\Admin\AppData\Local\Temp\tmp-andami" , "read";
permission java.security.AllPermission;
The problem is that in that PATH file or folder "tmp-andami" does not exist (maybe it is hidden), so I dont know if it is a problem of permission or a problem that this files does not exist and therefore can not be read.
All this comes from a line that is written on my code:
private static final String tempDirectoryPath =
System.getProperty("java.io.tmpdir")+"/tmp-andami";
But I need to write this file, here or in another PATH, I dont care. I have tried to write the file under "C:/" but I got the same result.
Any idea about this issue? Am I doing something wrong?
Thank you very much!
But I am using the access to my filesystem from the "server" package side, not the "client" that contains the translatable code.
I thought it would be possible to do this.
So, what can I do? It should exist a way of accessing local file system, isn't it? Or at least an alternative way of doing the same.
And, what about placing this file under the local deployed app file system? I mean, under "war" directory or something like that. If the browser can access this folder to read .jars and so on, would it be possible to do the same but with another purpose?
Thanks for your help!
GWT compiles your code into JavaScript which runs in the browser. JavaScript does not have access to your filesystem (for good reason).
java.io.FilePermission is not listed in the JRE Emulation Reference so you can't use it in your client-side code, so this shouldn't even be able to be compiled with GWT.
You cannot read or write to temporary files on App Engine. You can read files that were uploaded with your app, but cannot write new files or access any files outside your application.
