Pressing the "Clear Files" button deletes the Images Folder without it ever being recreated.

This causes a java.io.FileNotFoundException for all the other buttons until the app is relaunched, at which time the Images Folder is recreated again.

I would like to submit a fix.

See:

After trying Toggle pending status for media files from official docs:

https://developer.android.com/training/data-storage/shared/media#toggle-pending-status

I get exception:

java.lang.IllegalArgumentException: Movement of content://media/external_primary/video/media which isn't part of well-defined collection not allowed
at android.content.ContentProviderProxy.update(ContentProviderNative.java:578)

Hello,

I have researched how to solve this "issue" in the documentation and on the web, but unfortunately was not able to find anything.
We are currently running the Android 11 In the project I am working on, we have the all files permissions in the code, so everytime the application starts on a new device, it will ask for the permissions. However, in Android 12, instead of displaying only the application that is requesting all files permissions, it displays all the applications when our application is requesting access.

It is important to highlight that our code is following Android's documentation and we are using the ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION

Is there a way to prevent this behaviour just displaying our app's permissions? We want to avoid this behaviour, since users can change the settings for other app's and that's potentially dangerous for our user.

Thanks in Advance

Fix for the issue #3 regarding a problem with the instant-run feature.

kyunghoj included the following code: https://github.com/googlesamples/android-StorageProvider/pull/4/commits

android 11 /storage/emulated/0/Download/Driver.apk: open failed: EACCES (Permission denied)

I installed MediaStore V1.0 onto my Android running V10
I selected an image to delete from the images displayed within the app, clicked delete and the image appeared to be deleted. However, when I then opened the phone's default image viewer the image was still there. On opening the file explorer I could still see the file: /storage/sdcard0/DCIM/Camera/IMG_20210119_190148.jpg when viewing by folder, but the image was missing when viewing by image type.
When I returned to the MediaStore app, the file was no longer visible. It therefore appears that some reference to the image file is deleted, and not the actual file.

I'm trying to delete audio files (that were copied to the device from USB) from the external storage.
After analyzing the MediaStore sample, I ended up with the following solution for API 28 and earlier:

fun deleteTracks(trackIds: LongArray): Int {
    val whereClause = buildWildcardInClause(trackIds.size) // _id IN (?, ?, ?, ...)
    return resolver.delete(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, whereClause, Array(trackIds.size) { trackIds[it].toString() })
}

I noticed that the above code only deletes tracks from the MediaStore database and not from the device (files are re-added to the MediaStore after rebooting). So I modified that code to query the Media.DATA column, then use that information to delete the associated files. This works as intended.

But now that Android Q introduced scoped storage, Media.DATA (and Albums.ALBUM_ART) are now deprecated because the app may be unable to access those files. ContentResolver.openFileDescriptor can only be used to read files, not delete them.

Then what is the recommended way to delete tracks as of Android Q ?
The sample does not show how to delete multiple files from the MediaStore, and MediaStore.Audio.Media seems to work differently than MediaStore.Images.Media.

In the module ActionOpenDocument, there's no PERMISSIONS declared in AndroidManifest.xml.

Does that mean we have the access to all URI returned by system chooser?
Like Intent.ACTION_PICK, Intent.ACTION_GET_CONTENT,Intent.ACTION_OPEN_DOCUMENT etc.

I can not find any official info about this.

What I've implemented is choose an image from gallery then set it to an ImageView.
Tested on several devices it works fine. (Pixel 3 Android 12, Samsung S8 Android 7, ...)
Only one Chinese Model(Android 8.1) crashed and reported SecurityException.

gh pr checkout 109

As the title, is there any sample or way that I can query with some relative path?
I know we can do it when inserting, but when searching, can we do the same thing?

At MediaStoreFragment line 50, there is redundant line.

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {

        binding.recyclerView

        return binding.root
    }

I am studying Documents Providers and I have found something that I cannot understand, which also happens with the "StorageProvider" example of this repository.

It appears that all functions are called more than once when I open SAF.

Is it normal for queryDocument() and openDocument () to be called so many times?
That way, if my document provider were to download a file over the network, wouldn't it be downloaded multiple times?

can the onActivityResult Deprecated be fixed / updated!?

Use case - Currently I'm working on video uploading module. To get the video i have fired SFA video picker intent but I can't get any way or code to get the video details from uri in OnActivityResult even i have watched Google IO 19 Preparing Scoped Storage Video but there also not provided any sample code how to do that. ( Video details mean duration size name resolution and name )

To get the video details we have to use MediaStore api which recommended one and MediaStore only works with content URIs if i pass file uri then cursor will be always null
and we only get the content uri when cursor isnot null

Hoping to will answer my question someone

I tested the MediaStore sample on the Redmi Note 9 device, Android Q. Only several photos are loaded, other leave as blank.

It only works normal with requestLegacyExternalStorage.

I've been following latest documentation and tried to open the files after all permissions check mentioned in the docs. I thought I might be missing something, ergo, after checking the FileManager sample, it seems openFile() extension from FileManager sample is also helpless in opening the file. I tried to open a word file (.docx) an image file, a pdf file. It opens the app but the file can't be found and (Adobe Reader, Word and Gallery shows the main screen).

Tested with Realme 5 Pro (Android 10) with all permissions granted

fun openFile(activity: AppCompatActivity, selectedItem: File) {
    // Get URI and MIME type of file
    val uri = Uri.fromFile(selectedItem).normalizeScheme()
    val mime: String = getMimeType(uri.toString())

    // Open file with user selected app
    val intent = Intent()
    intent.action = Intent.ACTION_VIEW
    intent.data = uri
    intent.type = mime
    return activity.startActivity(intent)
}

This repository was archived:

https://github.com/googlearchive/android-DirectShare

and the only link it says it moved to is here, but I don't see any sample of it here.
Also, there was a rumor that Google works on a new sharing technique of files, that will replace Android-Beam. Maybe it's a good idea to show how to use it here too?

Though this example is not what I was looking for, just gonna leave this issue here. 😃

Android Studio won't build newest build because it uses AppCompat, try adding compile "com.android.support:appcompat-v7:23.0.0"to the dependencies in the Application build.gradle. 👍

You may have this issue elsewhere that auto-updates builds like this.

Made an issue here because the link under Support is broken.

In for code segment, lastModifiedFiles.remove() will modify PriorityQueue size, so lastModifiedFiles.size() always change, this is logic error.

I am learning android and I seen your example, and I implemented my provider in my first application

https://github.com/DarioLobos/sistemariego

but when I erase files using the file manager In my list of UI files still are showed. I try to clean it using NotifyChanges without any implementation that can update the list For example this.:

 context = root.getContext();

    Uri emptyUri= DocumentsContract.buildRootUri(AUTORITY, EMPTY);

(this Is a root with only the id empty and column MY_TYPE_DIR, trying to clean thelist)

    context.getContentResolver().notifyChange(emptyUri,null);

    Uri rootUri = DocumentsContract.buildRootUri(AUTORITY, ROOT);

    ContentObserver observer = new ContentObserver(null) {
        @Override
                  public boolean deliverSelfNotifications() {
                       return super.deliverSelfNotifications();
                  }
              };

    context.getContentResolver().notifyChange(rootUri,observer);
    context.getContentResolver().registerContentObserver(rootUri,true,observer);
    observer.dispatchChange(true,rootUri);

    Uri documentsInRoot = DocumentsContract.buildSearchDocumentsUri(AUTORITY, ROOT,"");  

I did it in the fragment that use to request the save open file. BUT DONT ERASE THE GOST FILES ERASED FROM FILE MANAGER IN ANY WAY.

Do you have any example to clean the erased files from other apps ? Many thanks in advance.

What is the bestway to pick a video file and get real path to upload to server. Seems from Android 10, it is very hard.

I have implemented this sample in my project... Everything was ok but when I try to convert the content uri to File to upload the image to server.. it throws an error.....

Security Exception. In Android 10

If I enable legacy in androidmanifest.xml file then it is ok...

If it shows a security exception why u make this sample recently?

What is the alternative...what is the uses of this sample if i can't use the image I pick?????

Hi Android Team

Thanks for sharing android examples projects.

I'm using Android 4.0.1 and opening this project:

I have an implementation of document provider, why is it that the cancellation signal is always null, when someone tries to opendocument from documentprovider ?

Thanks for your time!

It was possible before using file-path, but now I can't see of a way to do it, to get various APK information on the file system, such as app-icon and app-name:

https://developer.android.com/reference/android/content/pm/PackageManager.html#getPackageArchiveInfo(java.lang.String,%20int)

Forcing us to use SAF (on Q) instead of storage permission should also offer us alternatives to all of the Android framework functions.

writeDummyFilesToStorage() checks mBaseDir directory for an existing sub-directory to see if sample files have been already copied. But with a newer Android Studio, if instant-run is enabled, there is actually a directory named instant-run/, so this code does not copy sample image files.

Sometimes we would prefer to show some apps before others, and sometimes only very specific apps.

This was possible before using EXTRA_INITIAL_INTENTS , but for some reason it seems it can show now only up to 2 items and that's it. No customization potential as before.

I hope I'm wrong about this, so please share a sample of how to do it, just like before Android Q.

Steps to Reproduce:

• Clone the repo
• Attempt to build the app

Expected Results: for the app to build

Actual Results: the app fails with compile errors on references to Intent.EXTRA_SHORTCUT_ID, as that is new to Android Q but the Application module's compileSdkVersion is 28

Workaround: change Application/build.gradle to use compileSdkVersion 'android-Q'

Platform:Android 9

How to get hidden folder using MediaStore

I have android device which is rooted. I need to perform Runtime.getRuntime().exec("su") .and I have added READ_LOGs permission in manifest also. But even though i have root device its still gives me access denied. I have seen most of the blogs still the issue remains same. Can you please tell me Is there anything missing here

Currently the StorageProvider sample does allow for the creation of directories, it makes an empty file.

I'm trying to run ActionOpenDocumentTree and ActionOpenDocument with Emulator Android 6 and 5 but my docx and pdf files not showing in the native file picker, but it will show if I have some third-party file manager installed.

I am using Files.copy API (Package: java.nio.file) for copying images to new directory. The operation is working fine and I can see files are copied properly in new directory. But those newly copied files are not visible in Gallery by default.

If if use default file manager and try to move those newly copied files again in new folder then that new folder is immediately visible in phone gallery.

Do I need any change here? or I am missing something ?

Code snippet which I am using:

for (Path srcPath : sourcePaths) {
                String fileName = srcPath.getFileName().toString();
                File targetFile = new File(SDCARD_PATH + TARGET_PATH + fileName);


                if (!fileName.equalsIgnoreCase(".nomedia") && !targetFile.exists()) {
                    Files.copy(srcPath, targetFile.toPath(), StandardCopyOption.COPY_ATTRIBUTES);
                }
            }

In the MediaStore sample we currently load images in onResume, which isn't really best practice. We should switch to creating a ContentObserver and using the callbacks from it to update the LiveData.

seems that just update this line in action script to 1.11 would make it work. But needs to make sure other samples could take it.

Previously, we could use EXTRA_INITIAL_INTENTS to choose exactly which exact intents items to show, and in which order:

How can we do the same now when choosing to share?

On Q, now when I use EXTRA_INITIAL_INTENTS, it can show only up to 2 items, and that's it. Can't show more than that, and it's terrible.

Here's what happens when I try to show 3 items, of "com.ghisler.android.TotalCommander", "com.google.android.gm","com.whatsapp" :

Some consumers of DocumentsProviders (like the Files app on Chrome OS) require these functions to provide full functionality. These functions should be added to the official sample for testing and reference.
