Choose multiple text files from file manager

I have one edit text. I want to pick multiple files and read them and write to the edit text (I want to concat multiple files and show in edit text). Currently, I can pick only a single file from the file manager, and there is no problem.
I tried many of the StackOverflow suggestions but there is no of use.
this is for picking the single file from the file manager.
if (id == R.id.actionOpen) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
+ "/Speech Data/");
intent.setDataAndType(uri, "text/plain");
startActivityForResult(Intent.createChooser(intent, "Open folder"), PICK_FILE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_FILE) {
if (resultCode == RESULT_OK) {
Uri uri = data.getData();
String fileContent = readTextFile(uri);
vocalText.setText(fileContent);
}
}
}
private String readTextFile(Uri uri) {
BufferedReader reader = null;
StringBuilder builder = new StringBuilder();
try {
reader = new BufferedReader(new InputStreamReader(getContentResolver().openInputStream(uri)));
String line = "";
while ((line = reader.readLine()) != null) {
builder.append(line);
}
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
return builder.toString();
}

Place this in onActivityResult
if(null != data.getClipData()) { // checking multiple selection or not
for(int i = 0; i < data.getClipData().getItemCount(); i++) {
Uri uri = data.getClipData().getItemAt(i).getUri();
}
} else {
Uri uri = data.getData();
}

How can I get the path from a file

I'm making an App where I call the file explorer, the when I choose a file i get the name with file.getName() and put it in a TextView and get the path with file..getPath() and save it in a String, this String I use it to attach the file into a mail... my problem is that when a choose a file like .PDF, .DOC, .DOCX, .MP3 I can attach it but when a select an image I get this kind of path: "/media/external/images/media/1220" and does not attach anithing, I've been serarching everywhere and use almost every option I have found with no result.
Here is my code:
private void PickFile(View v) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
startActivityForResult(intent, PICKER);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if ((resultCode == RESULT_OK) && (requestCode == PICKER)) {
String FilePath = data.getData().getPath();
File file = new File(FilePath);
}
if (txtAdjunto1.getText() == "_") {
adjunto1 = file.getPath();// I get the path to add it to the MimeBodyPart
txtAdjunto1.setText(file.getName());// I put the name in the TextView
I've been trying this:
public String getRealPathFromURI(Uri contentUri) {
Cursor cursor = null;
int column_index;
String ruta = null;
try {
String[] proj = { MediaStore.Images.Media.DATA };
cursor = getContentResolver().query(contentUri, proj, null, null, null);
if (cursor != null){
column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
ruta = cursor.getString(column_index);
}
return ruta;
} finally {
if (cursor != null) {
cursor.close();
}
}
But the app crashes when I pick the file.
Also tried this:
file = new File(file.getAbsolutePath());
But still geting this "/media/external/images/media/1220"...
Hop someone can help me with this, and thanks in advance

ACTION_GET_CONTENT and ACTION_OPEN_DOCUMENT allow the user to choose a piece of content. That content might be a local file. That content might also be:
Something on a file server on the network
Something in a cloud storage service, such as Google Drive
Something in an encrypted volume
Something that is a file, but is not a file that you can access directly
And so on
You have two main options. If you only want files, then use a third-party file chooser library to replace all of the code in your question.
Or, you can take the Uri that you get from data.getData() in onActivityResult() and do two things with it:
First, use DocumentFile.fromSingleUri() to get a DocumentFile object pointing to that Uri. You can call getName() on the DocumentFile to get a "display name" for the content, which should be something that the user will recognize.
Then, use a ContentResolver and openInputStream() to get at the content itself, similar to how you might use a FileInputStream to get at the bytes in a file.

Try this...
The following code is to select any type of file from file manager and camera then convert to byte array and attach file make edit as per your requirement
private void selectFile() {
final CharSequence[] items = {"Camera", "Choose from File Manager",
"Cancel"};
AlertDialog.Builder builder = new AlertDialog.Builder(ComposeActivity.this);
builder.setTitle("Add Attachment!");
builder.setItems(items, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
boolean result = Constant.checkPermission(ComposeActivity.this);
if (items[item].equals("Camera")) {
userChoosenTask = "Camera";//String
if (result)
cameraIntent();
} else if (items[item].equals("Choose from File Manager")) {
userChoosenTask = "Choose from File Manager";//String
if (result) {
FileManagerIntent();
}
} else if (items[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);

Picking an Image File From an External SD Card (USB OTG Storage)

i saw this question:
How app can access files on USB OTG storages in Android 6.0 (API level 23) without root?
but it did not answer my question. i have an external SD card that i would like to access from my app and copy images from it to an internal storage. is this possible?
i am using android nouget
this is what i have done so far...

Upload image from devide to FTP using android app

Hey I have a code that let the user pick an image from the gallery and after he chooses the image is shown in an image view, now when the user click a button it should upload the image to ftp server , but from some reason the app tells me that the location of the file I am giving is not found.
here is the ftp upload code (I execute it using asynctask)
public UploadImage(String host,int port,String username,String password,String imagePath) {
this.host = host;
this.port = port;
this.username = username;
this.password = password;
this.imagePath = imagePath;
}
public void uploadingFilestoFtp() throws IOException
{
FTPClient con = null;
try
{
con = new FTPClient();
con.connect(host);
if (con.login(username, password))
{
con.enterLocalPassiveMode(); // important!
con.setFileType(FTP.BINARY_FILE_TYPE);
Uri uri = Uri.parse(this.imagePath);
String data = uri.getPath();
FileInputStream in = new FileInputStream(new File(data));
boolean result = con.storeFile("/img.png", in);
in.close();
if (result) Log.v("upload result", "succeeded");
con.logout();
con.disconnect();
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
and the loading file to imageview
loadedImage = (ImageView)findViewById(R.id.upload_image1);
Drawable drawable = loadedImage.getDrawable();
if(drawable.getConstantState().equals(getResources().getDrawable(R.drawable.camera_icon).getConstantState())) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "SelectPicture"), SELECT_PICTURE);
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
selectedImageURI = data.getData();
loadedImage = (ImageView)findViewById(R.id.upload_image1);
loadedImage.setScaleType(ImageView.ScaleType.CENTER_CROP);
Glide.with(this).load(selectedImageURI)
.into((ImageView) findViewById(R.id.upload_image1));
ImageView m =(ImageView)findViewById(R.id.remove_image);
m.setFocusable(true);
m.setVisibility(View.VISIBLE);
}
}
}
The imagePath String is the image uri converted to string.
can anyone help me and tell me why isn't it finding the file?

Ask user to pick the image and use that image to imageView.. the path consist of the actual image path you can upload it..
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
uri = data.getData();
if (uri != null)
{
path = uri.toString();
if (path.toLowerCase().startsWith("file://"))
{
// Selected file/directory path is below
path = (new File(URI.create(path))).getAbsolutePath();
}
else{
path = getRealPathFromUri(getApplicationContext(),uri);
}
}
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
profileImg.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
}
public static String getRealPathFromUri(Context context, Uri contentUri) {
Cursor cursor = null;
try {
String[] proj = { MediaStore.Images.Media.DATA };
cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} finally {
if (cursor != null) {
cursor.close();
}
}

Android Create String from XML-filepath

In my app the user can select a xml file via an Intent:
Selecting:
Intent chooseFileXML = new Intent(Intent.ACTION_GET_CONTENT);
chooseFileXML.setType("text/xml");
Intent intentXML = Intent.createChooser(chooseFileXML, getString(R.string.importXMLDatei));
startActivityForResult(intentXML, REQUEST_CODE_IMPORT_XML_FILE);
Receiving:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
switch (requestCode){
case REQUEST_CODE_IMPORT_XML_FILE:
if(resultCode == RESULT_OK){
Uri uri = data.getData();
String filePath = uri.getPath();
File fl = new File(filePath);
//Get xml-code from file and put it in a String
FileInputStream fin = null;
try {
fin = new FileInputStream(fl);
BufferedReader reader = new BufferedReader(new InputStreamReader(fin));
StringBuilder sb = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
sb.append(line).append("\n");
}
reader.close();
System.out.println(sb.toString());
fin.close();
} catch (Exception e) {
e.printStackTrace();
}
}
break;
}
}
I receive the correct filepath. But in this line: fin = new FileInputStream(fl); I get this error:
java.io.FileNotFoundException: /document/primary:Android/data/com.oli.myapp/Files/test.xml: open failed: ENOENT (No such file or directory)

Actually problem in file path .your file path is not vaild so find real path of file
String filePath = getRealPathFromURI(uri);
getRealPathFromURI methods
private String getRealPathFromURI(Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
CursorLoader loader = new CursorLoader(mContext, contentUri, proj, null, null, null);
Cursor cursor = loader.loadInBackground();
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String result = cursor.getString(column_index);
cursor.close();
return result;
}
