How to share a recorded video programmatically?

Well guys, I'm new at programming, I've tried some ways, but I was not able to achieve it.
I have these two paths, how can I open the share options to send this file?
I/ExternalStorage: Scanned /storage/emulated/0/Movies/HD2022-04-23-22-37-44.mp4:
I/ExternalStorage: -> uri=content://media/external_primary/video/media/102870
I did it with text, but I was not able to do it with the video, it's something like this?
binding.btShare.setOnClickListener {
ShareCompat.IntentBuilder(this)
.setType("text/plain")
.setChooserTitle(R.string.shareFriends)
.setText(getString(R.string.shareMessage)+" https://play.google.com/store/apps/details?id=" + this.getPackageName())
.startChooser();
}

No more need. thx...
Already did.
I'll put it here, maybe it can help someone.
fun shareVideo(filePath:String) {
val videoFile = File(filePath)
val videoURI = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N)
FileProvider.getUriForFile(this,BuildConfig.APPLICATION_ID + ".fileprovider", videoFile)
else
Uri.fromFile(videoFile)
ShareCompat.IntentBuilder.from(this)
.setStream(videoURI)
.setType("video/mp4")
.setChooserTitle("Share video...")
.startChooser()
}

Android unable to understand kotlin function

I am not very well versed with Kotlin and I am preferring Java over Kotlin while learning Android. But I am stuck at a piece of code which is as follows:
private fun getOutputDirectory(): File {
val mediaDir = externalMediaDirs.firstOrNull()?.let {
File(it, resources.getString(R.string.app_name)).apply { mkdirs() } }
return if (mediaDir != null && mediaDir.exists())
mediaDir else filesDir
}
The following function is called in onCreate method as var outputDirectory: File = getOutputDirectory();
Can you please help me convert the code into Java and in understanding it?
Thank you.

private File getOutputDirectory() {
File mediaDir = null;
if (getExternalMediaDirs().size > 0) {
mediaDir = new File(getExternalMediaDirs()[0], getResources().getString(R.string.app_name));
mediaDir.mkdirs();
}
return if (mediaDir != null && mediaDir.exists())
mediaDir
else
filesDir
}

Here is the process on how to convert Kotlin code to Java code.

But I suggest you to learn Kotlin as it is faster and preferred for Android app development.

Upload PDF to server failed with android studio retrofit [duplicate]

I have an Android app that needs to let the user select some pictures from the gallery and send these pictures to the backend (together with some other data).
To allow the user to select the pictures I have the following in my Fragment:
private void pickImages() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
startActivityForResult(intent, PICK_PHOTO_FOR_AVATAR);
}
I get the result of the selected photos by the user in here:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_PHOTO_FOR_AVATAR && resultCode == Activity.RESULT_OK) {
if (data == null) {
//Display an error
Toast.makeText(getActivity(), "There was an error getting the pictures", Toast.LENGTH_LONG).show();
return;
}
ClipData clipData = data.getClipData();
String fileName = null, extension = null;
//if ClipData is null, then we have a regular file
if (clipData == null) {
//get the selected file uri
fileName = FileUtils.getPath(getActivity(), data.getData());
//obtain the extension of the file
int index = fileName.lastIndexOf('.');
if (index > 0) {
extension = fileName.substring(index + 1);
if (extension.equals("jpg") || extension.equals("png") || extension.equals("bmp") || extension.equals("jpeg"))
isAttachedFile = true;
}
}
ArrayList<Uri> photosUris = new ArrayList<>();
//for each image in the list of images, add it to the filesUris
if (clipData != null) for (int i = 0; i < clipData.getItemCount(); i++) {
ClipData.Item item = clipData.getItemAt(i);
Uri uri = item.getUri();
switch (i) {
case 0:
picture1Uri = uri;
break;
case 1:
picture2Uri = uri;
break;
}
photosUris.add(uri);
}
else if (isAttachedFile) {
Uri uri = Uri.parse(fileName);
picture1Uri = uri;
photosUris.add(uri);
}
uris = photosUris;
if (picture1Uri != null) {
image1.setVisibility(View.VISIBLE);
image1.setImageURI(picture1Uri);
}
if (picture2Uri != null) {
image2.setVisibility(View.VISIBLE);
image2.setImageURI(picture2Uri);
}
}
I then send the list of URIs to the Presenter, where I execute my MultiPart Retrofit call to the backend:
//obtain the file(s) information of the message, if any
if (uris != null && uris.size() > 0) {
for (int i = 0; i < uris.size(); i++) {
File file = null;
//this is the corect way to encode the pictures
String encodedPath = uris.get(i).getEncodedPath();
file = new File(encodedPath);
builder.addFormDataPart("photos[]", file.getName(), RequestBody.create(MediaType.parse("multipart/form-data"), file));
}
}
MultipartBody requestBody = builder.build();
//send the newly generated ticket
Call<GenerateNewTicketResponse> generateNewTicketCall = OperatorApplication.getApiClient().generateNewTicket(Constants.BEARER + accessToken, requestBody);
The problem is that this sometimes works, sometimes doesn't. Sometimes I get the error "java.io.FileNotFoundException", which throws me in the onFailure() callback of the Retrofit call.
I found the following stackoverflow post Reading File from Uri gives java.io.FileNotFoundException: open failed: ENOENT but I'm not exactly sure how to implement the general suggestion in that response to my particular situation.
What would be the right way to get the right path towards the pictures selected by the user such that I can create files out of them and attach them in my MultiPart request?
Commonsware suggested to
Use a ContentResolver and openInputStream() to get an InputStream on the content pointed to by the Uri. Then, pass that to your decoding logic, such as BitmapFactory and its decodeStream() method.
, but I'm not sure exactly how to do that programmatically.
Any help would be appreciated.

To allow the user to select the pictures I have the following in my Fragment:
This code is using ACTION_GET_CONTENT. Particularly on Android 7.0+, generally that (and ACTION_OPEN_DOCUMENT) will return Uri values with a content scheme. Your code assumes that you are getting Uri values with a file scheme, where the path actually has meaning. Moreover, your code assumes that the user is picking files on the filesystem that you can access, and there is nothing that forces the user to do that. ACTION_GET_CONTENT can be supported by apps where their content is:
A local file on external storage
A local file on internal storage for the other app
A local file on removable storage
A local file that is encrypted and needs to be decrypted on the fly
A stream of bytes held in a BLOB column in a database
A piece of content on the Internet that needs to be downloaded by the other app first
Content that is generated on the fly
...and so on
Instead of using RequestBody.create(), use the InputStreamRequestBody from this OkHttp issue comment. You provide the same media type as before, but instead of a File (that you are incorrectly creating), you provide a ContentResolver (from getContentResolver() on a Context) and the Uri.
This blog post demonstrates how to use InputStreamRequestBody (specifically a Kotlin port of the original) to upload content in this fashion. This blog post provides another look at the same problem and a similar solution.

Create a file from a photo URI on Android

Fastest/shortest way to the root folders?

I'm using Google Drive SDK v2 on Android to get the list of root folders. Currently I see these required steps - which seem to load forever. Is there no faster way?
I tried to use the search with the q= parameter but I don't get it to work (FileList vs. Files.List) - different API levels?
FileList files = drive.files().list().setQ("'root' in parents and mimeType='application/vnd.google-apps.folder' and trashed=false");
This is what I do currently:
About about = drive.about().get().execute();
if (about != null) {
ChildList childList = drive.children().list(about.getRootFolderId()).execute();
if (childList != null) {
List<ChildReference> listChildReference = childList.getItems();
for (ChildReference childReference : listChildReference) {
File file = drive.files().get(childReference.getId()).execute();
if (file != null) {
String fileExtension = file.getFileExtension();
String mimeType = file.getMimeType();
if (mimeType != null
&& mimeType.equals("application/vnd.google-apps.folder")
&& (fileExtension == null || fileExtension.equals(""))) {
Log.d(this.getClass().getName(), file.getTitle());
}
}
}
}
}
What's the fastest for an Android app?
Thanks in advance.

My personal opinion is avoid the Drive SDK and call the REST API directly. It's a fairly simple API, and the way the documentation is structured, you are forced to understand it anyway in order to use the SDK. You have the benefit that if something doesn't work, you can directly compare your app with what's happening on the wire and resolve any problems.

Found it:
#Override
protected ArrayList<File> doInBackground(final Void... voids) {
ArrayList<File> result = new ArrayList<File>();
Files.List request = null;
boolean ok = true;
do {
try {
request = drive
.files()
.list()
.setMaxResults(200)
.setQ("'root' in parents and mimeType='application/vnd.google-apps.folder' and trashed=false");
FileList files = request.execute();
result.addAll(files.getItems());
request.setPageToken(files.getNextPageToken());
} catch (IOException exception) {
ok = false;
}
} while (ok && request.getPageToken() != null && request.getPageToken().length() > 0);
return result;
}
