Android - How to get selected file name from the document - android

I am launching the intent for selecting documnets using following code.
private void showFileChooser() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
try {
startActivityForResult(
Intent.createChooser(intent, "Select a File to Upload"), 1);
} catch (android.content.ActivityNotFoundException ex) {
// Potentially direct the user to the Market with a Dialog
Toast.makeText(this, "Please install a File Manager.",
Toast.LENGTH_SHORT).show();
}
}
In onActivity results when i am trying to get the file path it is giving some other number in the place of file name.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case 1:
if (resultCode == RESULT_OK) {
// Get the Uri of the selected file
Uri uri = data.getData();
File myFile = new File(uri.toString());
String path = myFile.getAbsolutePath();
}
break;
}
super.onActivityResult(requestCode, resultCode, data);
}
That path value i am getting like this.
"content://com.android.providers.downloads.documents/document/1433"
But i want real file name like doc1.pdf etc.. How to get it?

When you get a content:// uri, you'll need to query a content resolver and then grab the display name.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case 1:
if (resultCode == RESULT_OK) {
// Get the Uri of the selected file
Uri uri = data.getData();
String uriString = uri.toString();
File myFile = new File(uriString);
String path = myFile.getAbsolutePath();
String displayName = null;
if (uriString.startsWith("content://")) {
Cursor cursor = null;
try {
cursor = getActivity().getContentResolver().query(uri, null, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
displayName = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
}
} finally {
cursor.close();
}
} else if (uriString.startsWith("file://")) {
displayName = myFile.getName();
}
}
break;
}
super.onActivityResult(requestCode, resultCode, data);
}

First Check if the permission is granted for Application.. Below method is used to check run-time permission'
public void onClick(View v) {
//Checks if the permission is Enabled or not...
if (ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.READ_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(thisActivity,
new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
REQUEST_PERMISSION);
} else {
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, USER_IMG_REQUEST);
}
}
and below method is used to find the uri path name of the file
private String getRealPathFromUri(Uri uri) {
String[] projection = {MediaStore.Images.Media.DATA};
CursorLoader cursorLoader = new CursorLoader(thisActivity, uri, projection, null, null, null);
Cursor cursor = cursorLoader.loadInBackground();
int column = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String result = cursor.getString(column);
cursor.close();
return result;
}
and the above method can be used as
if (requestCode == USER_IMG_REQUEST && resultCode == RESULT_OK && data != null) {
Uri path = data.getData();
try {
String imagePath = getRealPathFromUri(path);
File file = new File(imagePath);
RequestBody reqFile = RequestBody.create(MediaType.parse("image/*"), file);
MultipartBody.Part imageFile = MultipartBody.Part.createFormData("userImage", file.getName(), reqFile);

You can try this,m I hope it will help u:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.i("inside", "onActivityResult");
if(requestCode == FILE_MANAGER_REQUEST_CODE)
{
// Check if the user actually selected an image:
if(resultCode == Activity.RESULT_OK)
{
// This gets the URI of the image the user selected:
Uri selectedFileURI = data.getData();
File file = new File(getRealPathFromURI(selectedFileURI));
// Create a new Intent to send to the next Activity:
}
}
}
private String getRealPathFromURI(Uri contentURI) {
String result;
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null) { // Source is Dropbox or other similar local file path
result = contentURI.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
result = cursor.getString(idx);
cursor.close();
}
return result;
}

Here is the complete solution:
Pass your context and URI object from onActivityResult to below function to get the correct path:
it gives the path as /storage/emulated/0/APMC Mahuva/Report20-11-2017.pdf (where I've selected this Report20-11-2017.pdf file)
String getFilePath(Context cntx, Uri uri) {
Cursor cursor = null;
try {
String[] arr = { MediaStore.Images.Media.DATA };
cursor = cntx.getContentResolver().query(uri, arr, 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();
}
}
}

Can not load image from file path to ImageView with Glide

I'm trying to get image from gallery and store the path to the database for further use.
File path is saved in database but I am unable to get the view on ImageView.
File path is: /storage/emulated/0/DCIM/Camera/image.jpg
Here I'm getting the image path as imgS
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && requestCode == PICK_IMAGE) {
imageUri = data.getData();
img.setImageURI(imageUri);
imgS = getPath(getApplicationContext(), imageUri);
}
}
public static String getPath(Context context, Uri uri) {
String result = null;
Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
if (cursor != null) {
if (cursor.moveToFirst()) {
int column_index = cursor.getColumnIndex("_data");
result = cursor.getString(column_index);
}
cursor.close();
}
if (result == null) {
result = "Not found";
}
return result;
}
Here I'm trying to retrieve the path and show the image in image view.
File f = new File(item.getImg());
Glide.with(c).load(f).into(holder.img);
holder.img.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Toast.makeText(c, f.getAbsolutePath(), Toast.LENGTH_SHORT).show();
if (f.exists()) {
Toast.makeText(c, f.getAbsolutePath(), Toast.LENGTH_SHORT).show();
}
}
});
Note: File exist at the path.
Just need to add android:requestLegacyExternalStorage="true" to Application tag in Manifest.xml .

how to get a real path of PDF file in android

we want to choose a pdf file using intent from a gallery so how can get a real path of a pdf file. We want to choose a PDF file from a gallery and upload this file on a server.
public String getPathFromURI(Context context, Uri contentUri) {
if ( contentUri.toString().indexOf("file:///") > -1 ){
return contentUri.getPath();
}
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();
}
}
}
Hi here is sample code for selecting pdf file from external storage and get file's path using which you can access file's data and upload data on your server.
Here PICK_IMAGE is any number you want as your request code.
Intent intent = new Intent();
intent.setType("application/pdf");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select File"),PICK_IMAGE);
public void onActivityResult(int requestCode, int resultCode, final Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE) {
try {
Uri uri1 = data.getData();
String path = String.valueOf(uri1);
String path_lastPart = path.substring(path.indexOf("/storage"));
if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
// Do the file write
path_lastPart = path_lastPart.replace("%20", " ");
File yourFile = new File(path_lastPart);
} else {
// Request permission from the user
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 0);
}
} catch (Exception e2) {
Log.e("macro", "" + e2);
}
}
}

Android How to Load an Audio file from the sdcard/file manager and play it

I'm developing an app, and in that app I have one button, named 'choose sound'. When user will click this button, he/she should be asked to choose any audio file from the file manager/memory.
So, I know that for this, I'll have to use Intent.Action_GetData. I'm doing the same:
//code start
Intent intent = new Intent();
intent.setType("audio/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent,1);
#Override
protected void onActivityResult(int requestCode,int resultCode,Intent data){
if(requestCode == 1){
if(resultCode == RESULT_OK){
//the selected audio.
Uri uri = data.getData();
int SoundID=soundPool.Load(uri.toString(), 1);
//SoundPool is already constructed and is working perfectly for the resource files
PlaySound(SoundID);
//PlaySound method is already defined
}
}
super.onActivityResult(requestCode, resultCode, data);
}
//end of code
but it's not working
Now, in OnActivityResult, I'm not getting that how to load the proper URI of the file selected by user, because before Android 4.4, it returns the different URI and after Android 4.4 it returns the different URI on intent.GetData();. Now, what I have to do?
Also, I know that for playing the audio file, I'll have to use SoundPool, and I have the code for that too, in fact it's working fine for the resource/raw/audio files, but how to load/play files in SoundPool from this URI?
In your onActivityResult(), do the following changes:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK && data != null)
{
String realPath = null;
Uri uriFromPath = null;
realPath = getPathForAudio(YourActivity.this, data.getData());
uriFromPath = Uri.fromFile(new File(realPath)); // use this uriFromPath for further operations
}
}
Add this method in your Activity:
public static String getPathForAudio(Context context, Uri uri)
{
String result = null;
Cursor cursor = null;
try {
String[] proj = { MediaStore.Audio.Media.DATA };
cursor = context.getContentResolver().query(uri, proj, null, null, null);
if (cursor == null) {
result = uri.getPath();
} else {
cursor.moveToFirst();
int column_index = cursor.getColumnIndex(MediaStore.Audio.AudioColumns.DATA);
result = cursor.getString(column_index);
cursor.close();
}
}
catch (Exception e)
{
e.printStackTrace();
}
finally {
if (cursor != null) {
cursor.close();
}
}
return result;
}
Hope It will do your job. You can play audio using MediaPlayer class also
You can put below codes in your project when you want to select audio.
Intent intent_upload = new Intent();
intent_upload.setType("audio/*");
intent_upload.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent_upload,1);
And override onActivityResult in the same Activity, as below
#Override
protected void onActivityResult(int requestCode,int resultCode,Intent data){
if(requestCode == 1){
if(resultCode == RESULT_OK){
//the selected audio.
Uri uri = data.getData();
}
}
super.onActivityResult(requestCode, resultCode, data);
}
Try to get the path :
//method to get the file path from uri
public String getPath(Uri uri) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
String document_id = cursor.getString(0);
document_id = document_id.substring(document_id.lastIndexOf(":") + 1);
cursor.close();
cursor = getContentResolver().query(
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null);
cursor.moveToFirst();
String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
cursor.close();
return path;
}
then load it :
s2 = soundPool.load(YOU_PATH, PRIORITY);

how to delete an image from android when its URI is known?

Im developing an android app which selects an image from the gallery in one activity and displays it in another.But when I try to delete the selected image it doesnt delete.I'm passing its uri between the two activies. Many thanks in Advance!!!!
Here's my Code :
ACTIVITY HOMESCREEN
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 uri = data.getData();
Intent i = new Intent(this, Imageviewer.class);
i.putExtra("imgpath", uri.toString());
startActivity(i);
}
}
IMAGEVIEWER ACTIVITY :
Uri imageUri;
imageUri = Uri.parse(intent.getStringExtra("imgpath"));
File fdelete = new File(imageUri.toString());
if (fdelete.exists()) {
if (fdelete.delete()) {
System.out.println("file Deleted :" );
} else {
System.out.println("file not Deleted :");
}
}
First you must take real path of image:
//getting real path from uri
private String getFilePath(Uri uri) {
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(projection[0]);
String picturePath = cursor.getString(columnIndex); // returns null
cursor.close();
return picturePath;
}
return null;
}
Then you can delete this file like below:
Uri imageUri;
imageUri = Uri.parse(intent.getStringExtra("imgpath"));
File fdelete = new File(getFilePath(imageUri));
if (fdelete.exists()) {
if (fdelete.delete()) {
System.out.println("file Deleted :" );
} else {
System.out.println("file not Deleted :");
}
}
Try this : (In the second Activity) ImageViewerActivity in your case.
Intent intent = getIntent();
String receivedPath = intent.getExtras().getString("imgpath");
File fdelete = new File(receivedPath);
if (fdelete.exists()) {
if (fdelete.delete()) {
System.out.println("file Deleted :" );
} else {
System.out.println("file not Deleted :");
}
}
Also you can debug your codes line by line to see and check if the ImgPath is getting correctly or not!
With kotlin you could do: uri.toFile().delete() and its deleted

[Android]Cannot get filepath

I don't konw why I cannot get file path.When I choose file,the message will show "Uploading file path:null"How can I fix it?
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
filepath = getPath(selectedImageUri);
Bitmap bitmap = BitmapFactory.decodeFile(filepath);
imageview.setImageBitmap(bitmap);
messageText.setText("Uploading file path:" + filepath);
}
}
#SuppressWarnings("deprecation")
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
<pre>
<code>
protected void onActivityResult(int requestCode, int resultCode, Intent intent)
{
if (requestCode == PICK_REQUEST_CODE)
{
if (resultCode == RESULT_OK)
{
Uri uri = intent.getData();
String type = intent.getType();
LogHelper.i(TAG,"Pick completed: "+ uri + " "+type);
if (uri != null)
{
String path = uri.toString();
if (path.toLowerCase().startsWith("file://"))
{
// Selected file/directory path is below
path = (new File(URI.create(path))).getAbsolutePath();
}
}
}
else LogHelper.i(TAG,"Back from pick with cancel status");
}
}
managedQuery has many issues, and its deprecated now. the replacement method is
getContentResolver().query()
