What it is

A 14-minute Android Developers talk by Roxanna Aliabadi on the storage changes in Android 11, building on Scoped Storage from Android 10. It covers batch edit requests for media files, file path access for apps that rely on the File API, and a new broad access permission for qualifying apps.

Be aware that the solution: <application ... android:requestLegacyExternalStorage="true" ... > Is temporary, sooner or later your app should be migrated to use Scoped Storage . In Android 10, you can use the suggested solution to bypass the system restrictions, but in Android 11 (R) it is mandatory to use scoped storage , and your app might break if you kept using the old logic! This video [this video] might be a good help.

Android change his security about Storage, For more details check the video Storage access with Android 10 [this video] Also you can try this in android 10 File mydir = new File(getApplicationContext().getExternalFilesDir("Directory Name").getAbsolutePath()); if (!mydir.exists()) { mydir.mkdirs(); Toast.makeText(getApplicationContext(),"Directory Created",Toast.LENGTH_LONG).show(); } The path of your directory will be in your app data.

From Android 10 with Scoped Storage if you are targeting to SDK 30 you can't access to others app's files even if they are in external storage, at least until you request and got the approval from Google to do so, specifically you will need All Files Access Permission [LINK] . To know more see this [this video] video resource in YouTube from the official Android Developers channel. You can temporary opt-out this restriction by setting your target SDK to 29 & using the requestLegacyExternalStorage flag to true in your app manifest, but you will need it to publish your app or app updates in the next November from this link about Google Play's target API level requirement [LINK] : Starting in Novemb

Android has done much to change its permission models around file access since Android 10 and 11. The preferred approach is to use Scoped Storage APIs [LINK] . Many of the old file read/write permissions are on life support and will no longer work. If they do continue to work, then must justify to Google why you need them, and then go through a security approval by Google. You will only be granted approval if you app is classified as a file browser application, or the like. Basically, the new model is to use Android's file browsers to gain access to read/write/update a particular file that the user selects, and defer the rest of the file management to Google's first-party applications.

In Android 10 scoped storage, forming File object with file path was completely restricted. However based on many feedbacks this was somewhat eased in Android 11 ( [this video] ). In the video it is mentioned that you can use File object and get access to the file with user consent by requesting the permission to do so. I am not able to figure out what permission should I be getting to edit the files using File object. I tried SAF, it didn't work. (I want to edit tags of audio file using ID3 tag editor library which takes input in the form of File. I tried getting permission using SAF it didn't work, I tried to get permission using MediaStore.createWriteRequest() even this didn't work) Edit 1 : I

You might be right that there is no way, I was hoping to get that confirmed. Is there docs on that? I had previously watched this video [this video] where it talks about the ability to work with SAF just like a file system... Starting at 4:20 in the video...at 5:10 the speaker talks about still allowing file path APIs for compatibility reasons. So I had hopes it could be done.

Cites Camillo · 2022-01 · Stack Overflow · on “Migrate folder in /storage/emulated/0/<my_folder> from Android 10 to 11”

In my existing app(Android 10) I have a folder under /storage/emulated/0/<my_folder> . After looking to various sources on Google Developers I don't think that it's possible to longer access the /storage/emulated/0/<my_folder> directory under Android 11, because of the changes made in storage access permission [this video] . Of course I can create these folder under Android 11 inside the so called "scoped storage" as mentioned by Google. But if a user updates the app from 10 to 11, how can I access the old folder for copying the files inside to the new folder inside "scoped storage" when I am on Android 11? Or is there some other way to migrate this folder under /storage/emulated/0/<my_folder> sa

Are you familiar with Filesystem in Userspace (FUSE)? According to this video FUSE was implemented to allow API's that use file paths instead of URI's (like LibGDX FileHandle?), but not a lot of specifics was provided: [this video] Googling this did not turn up much info, I can't find a tutorials or even an API for how to actually implement it. The section called "Filesystem in Userspace (FUSE)" mentions it, but not a lot of details: [LINK] This sounds promising, but I'm still not sure if it is a viable option.

This is improvised answer of @Shay Kin. As we know in latest android versions we have many restrictions to access files in external storage. MediaStore api [LINK] and Storage Access Framework [LINK] apis provides access to shared files. This is explained clearly in this video [this video] .
