I am trying to fetch a file this way:
final Intent chooseFileIntent = new Intent(Intent.ACTION_GET_CONTENT);
String[] mimetypes = {"application/pdf"};
chooseFileIntent.setType("*/*");
chooseFileIntent.addCategory(Intent.CATEGORY_OPENABLE);
if (chooseFileIntent.resolveActivity(activity
.getApplicationContext().getPackageManager()) != null) {
chooseFileIntent.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);
activity.startActivityForResult(chooseFileIntent, Uploader.PDF);
}
Then in onActivityResult :
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
}
According to many threads I'm supposed to fetch the file name from the intent with data.getData().getPath(), the file name I'm expecting is my_file.pdf, but instead I'm getting this :
/document/acc=1;doc=28
So what to do? Thanks for your help.

Not with that code. That code is asking the user to pick a piece of content. This may or may not be a file.
According to many threads I'm supposed to fetch the file name from the intent with data.getData().getPath()
That was never correct, though it tended to work on older versions of Android.
So what to do?
Well, that depends.
If you wish to only accept files, integrate a file chooser library instead of using ACTION_GET_CONTENT. (UPDATE 2019-04-06: since Android Q is banning most filesystem access, this solution is no longer practical)
If you are willing to allow the user to pick a piece of content using ACTION_GET_CONTENT, please understand that it does not have to be a file and it does not have to have something that resembles a filename. The closest that you will get:
If getScheme() of the Uri returns file, your original algorithm will work
If getScheme() of the Uri returns content, use DocumentFile.fromSingleUri() to create a DocumentFile, then call getName() on that DocumentFile — this should return a "display name" which should be recognizable to the user
To get the real name and to avoid getting a name that looks like "image: 4431" or even just a number, you can write code as recommended by CommonsWare.
The following is an example of a code that selects a single pdf file, prints its name and path to the log, and then sends the file by email using its uri.
private static final int FILEPICKER_RESULT_CODE = 1;
private static final int SEND_EMAIL_RESULT_CODE = 2;
private Uri fileUri;
private void chooseFile() {
Intent fileChooser = new Intent(Intent.ACTION_GET_CONTENT);
fileChooser.setType("application/pdf");
startActivityForResult(Intent.createChooser(fileChooser, "Choose one pdf file"), FILEPICKER_RESULT_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == FILEPICKER_RESULT_CODE) {
if (resultCode == RESULT_OK) {
fileUri = data != null ? data.getData() : null;
if (fileUri != null) {
DocumentFile d = DocumentFile.fromSingleUri(this, fileUri);
if (d != null) {
Log.d("TAG", "file name: " + d.getName());
Log.d("TAG", "file path: " + d.getUri().getPath());
sendEmail(fileUri);
}
}
}
}
}
private void sendEmail(Uri path) {
String email = "example#gmail.com";
Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("application/octet-stream");
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "PDF file");
String[] to = { email };
intent.putExtra(Intent.EXTRA_EMAIL, to);
intent.putExtra(Intent.EXTRA_TEXT, "This is the pdf file...");
intent.putExtra(Intent.EXTRA_STREAM, path);
startActivityForResult(Intent.createChooser(intent, "Send mail..."), SEND_EMAIL_RESULT_CODE);
}
hope it helps.

I'm developing an Android App that uses an Intent to open the in-built camera, and take a photo that then should be saved to storage and be sent to a different intent that crops it.
I've run the app a few times but can't see any of the photos being saved anywhere in storage. I started debugging the code and found that it was skipping out on the commands in the OnActivityResult method because the resultCode parameter was always going back as 0.
Out of curiosity I manually changed this to the required value of -1, and the code then skipped out on the next if statement because data.getExtras() (data being the Intent parameter) was returning null, even though I had been adding an extra in the code that triggered the Camera Activity.
I can't quite figure out what's happening here. I'd assume the image is saving somehow because no exception is being thrown, but don't see what might be causing the empty values of resultCode and data.
My code is shown below. If anyone can give me a point in the right direction, that would be a massive help!
Thanks,
Mark
public void onClick(DialogInterface dialogInterface, int i) {
if (optionItems[i].equals(OPTION_CAMERA)) {
//intent to open device camera
Intent cameraIntent =
new Intent(
MediaStore.ACTION_IMAGE_CAPTURE
);
//create 'Spond' folder inside photo directory
//target folder for image to be saved
File imagesFolder =
new File(
Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES),
getString(R.string.app_name)
);
//create directory if it doesn't already exist
imagesFolder.mkdirs(); //bool return value not needed
//create file with unique id
File image = createFileAtUniquePath(imagesFolder);
//use authority for AndroidManifest to create permission
//to get uri from temporary file in app
String fileProviderAuthority = getApplicationContext().getPackageName() +
getString(R.string.authorities_fileprovider);
Uri uriSavedImage = FileProvider.getUriForFile(
getApplicationContext(),
fileProviderAuthority,
image
);
//pass URI to intent so it will be available in activity result
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
//grant read/write permissions with file
cameraIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
cameraIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
startActivityForResult(cameraIntent, REQUEST_CAMERA);
The OnActivityResult code:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_CAMERA) {
if (data.getExtras() != null) {
newAccountPhotoUri = (Uri) data.getExtras().get(MediaStore.EXTRA_OUTPUT);
newAccountPhotoFileName = getFileNameFromURI(newAccountPhotoUri);
if (!newAccountPhotoFileName.equals("")) {
appAccountPhotoChanged = true;
//send image to be cropped
cropImage(newAccountPhotoUri);
}
}
}
//...

I getting an URI when try to pick a file :
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent,FILE_MANAGER_REQUEST_CODE);
In ActivityOnResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d("FilePick", "request code = " + requestCode + ", resultCode = " + resultCode);
Log.d("FilePick", "Intent = " + data != null ? data.getData().getPath() : null);
super.onActivityResult(requestCode, resultCode, data);
}
When i pick a file data.getData().getPath() returns
/external/file/15499
How i convert it to real file path?
Note: I read this topics :
Get filename and path from URI from mediastore
Get real path from URI, Android KitKat new storage access framework
But i think it's accessible onl;y for media content. Not for files.
There is no "real file path". A Uri is not a File.
Please use ContentResolver and methods like openInputStream() to consume the content.
//after user press select file btn
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
intent.setDataAndType(uri, "audio/*");
startActivity(Intent.createChooser(intent, "Open folder"));
//String path = uri.getPath();
//Toast.makeText(getApplicationContext(),path +"Selected File",
//Toast.LENGTH_LONG).show();
}
//after selected the file from the file chooser
static final int FILE_SELECTION_RESULT = 1;
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
EditText selectedFile;
if (requestCode == FILE_SELECTION_RESULT) {
if (resultCode == RESULT_OK) {
String filePath = data.getData().getPath();
Toast.makeText(getApplicationContext(), filePath, Toast.LENGTH_LONG).show();
//selectedFile = (EditText)findViewById(R.id.editText1);
//selectedFile.setText(data.getExtras().getString("selected_file"));
}
}
}
// i am not sure that i am doing this wrong or correct, please help me.. =(
Unfortunately, you can not open a folder with Intent. To solve this problem, you have two way:
1- force your users to install OI file explorer, an open source lite file browser that can handle ACTION_VIEW on folders, or
2- Write an activity to handle this action. MapsForge open source library has a simple file chooser. Take a look at that: https://code.google.com/p/mapsforge/
Instead of startActivity call startActivityForResult.
And inside onActivityResult just set the filePath to editText
