How to get file path from URI in Android N

How can I get the file path from Uri when I open a video file from file explore.
Uri host is "content" and "_data" return null.
I want to get other videos in the same directory thus i have to get the file path.if have any other way to get videos in the same directory without file path,it also work for me.
Thanks a lot for your any ideas and solutions.

Try this code. It works for me in Oreo as well.

This code requires the READ_EXTERNAL_STORAGE permission:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
This permission should be requested from the user at runtime as it is a dangerous permission.

Activity code:

Getting null value while upload pdf file from device memory

In my application i want to upload pdf file from device. So for that i have followed bellow link
[Android: Browse and upload a PDF or word file in application from the device
By using this code, after select pdf file getting null value. This getFileNameByUri method return null vlaue. I dont know, what is the issue hare. So please suggest me.
Thanks In Advance...
This the code i am using...
private void getDocument()
{
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("application/pdf");
intent.addCategory(Intent.CATEGORY_OPENABLE);
// Only the system receives the ACTION_OPEN_DOCUMENT, so no need to test.
startActivityForResult(intent, 1);
}
And this is the onactivity result
#Override
protected void onActivityResult(int req, int result, Intent data)
{
// TODO Auto-generated method stub
super.onActivityResult(req, result, data);
if (result == RESULT_OK)
{
Uri fileuri = data.getData();
docFilePath = getFileNameByUri(this, fileuri);
}
}
And this is the method for file path..
private String getFileNameByUri(Context context, Uri uri)
{
String filepath = "";//default fileName
//Uri filePathUri = uri;
File file;
if (uri.getScheme().toString().compareTo("content") == 0)
{
Cursor cursor = context.getContentResolver().query(uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA, MediaStore.Images.Media.ORIENTATION }, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String mImagePath = cursor.getString(column_index);
cursor.close();
filepath = mImagePath;
}
else
if (uri.getScheme().compareTo("file") == 0)
{
try
{
file = new File(new URI(uri.toString()));
if (file.exists())
filepath = file.getAbsolutePath();
}
catch (URISyntaxException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else
{
filepath = uri.getPath();
}
return filepath;
}
here this method getFileNameByUri returns null value..

This will get the file path from the MediaProvider, DownloadsProvider, and ExternalStorageProvider, while falling back to the unofficial ContentProvider method you mention.

I Am Working In A Project Where I Have To get audio, video , images from SdCard and upload to server
I get The Images Quite Easily but Issue Is With The Audio And Video . Where Cursor Return Null
I Have Android lollipop .
This Is Code :-
Cursor cursor = getActivity().managedQuery(selectedImageUri, projection, null,null, null);
int data_column_index = cursor.getColumnIndexOrThrow("_data");
int size_column_index = cursor.getColumnIndexOrThrow("_size");
int name_column_index = cursor.getColumnIndexOrThrow("_display_name");
It Returns null
Now I am using This :-
https://limbaniandroid.blogspot.in/2014/03/how-to-get-absolute-path-when-select.html
But issue is, it requires minimum SDK 19, Warning/error in android studio .But it is compiling and running fine . I have Android lollipop
so its good to kept moving with this . Or I have to do my projects minimum SDK 19
Will it produce any error while uploading assigned .apk .
Because I have to upload it within 2, 3 days
Or I have to write separate code for lower version
Any help please.

And in onActivityResult use:

super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case RESULT_LOAD_DOC:
if (resultCode == Activity.RESULT_OK && data != null) {
String selectedImagePath = ImagePathUtil.getPath(this, data.getData());
}
break;
}
}
where selectedImagePath will give you the path to use.
RESULT_LOAD_DOC is the identifier used to check which data is being fetched.

get realPath return null on android marshmallow?

I am using this function to get the image path from uri:
private 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();
}
}
}
the above function works fine with version < 23 . but it return null with android marshmallow ?
I am using emulator nexus 4 with android 6.0 x86_64
the emulator has storage permissions.
what may be the problem ?

UPDATE:
Please refer to this post on handling Uri in android to support the latest versions of the android operating system and new devices, most of the your requirements can be met with using streams instead of getting the path to the asset in the file system. So please consider using streams.

taken from here and from this answer . This is an ugly hack that isn't guaranteed to work on all devices but in my experience it works on 99% of the devices out there. According to CommonsWare you shouldn't assume, that the stream you get via ContentResolver is convertable into file. Instead you are supposed to open an inputstream from that Uri using the context.getContentResolver().openInputStream(fileUri) method. Refer to his commonsBlog post for more information on this and how to handle Uris

Get the path from Uri in Android Kitkat throws Illegal Argument exception

I'm trying to get the path from uri. it works in devices below kitkat. I googled and found that I need to get the document Id and then query it with the gallery items. And it works. But I'm facing problem with videos. When i select the video from Videos section, it works. But When I select it from Gallery, my app crashes, giving Illegal Argument exception- Not a document type. I know why it's happening. It is because I'm looking for a document type of video in Gallery section. But how to prevent this. So that I can select videos from both Gallery & Videos Section.
Here is my code:
public static String getRealPathFromURI(Context context, Uri contentUri,String type) {
if(isKitkatBelow()) {
String[] proj = { MediaStore.Images.Media.DATA };
Cursor 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);
}else{
String docId= DocumentsContract.getDocumentId(contentUri);
String id= docId.split(":")[1];
if(type== TYPE_IMAGE){
String[] proj = { MediaStore.Images.Media.DATA };
String whereClause=MediaStore.Images.Media._ID + "=?";
Cursor cursor=context.getContentResolver().query(getUri(type),proj,whereClause,new String[]{id},null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}else{
String[] proj = { MediaStore.Video.Media.DATA };
String whereClause=MediaStore.Video.Media._ID + "=?";
Cursor cursor=context.getContentResolver().query(getUri(type),proj,whereClause,new String[]{id},null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
}
}
This is happening because I'm trying to search a file of type MediaStore.Video.Media.DATA in Gallery. But for devices below kitkat, MediaStore.Images.Media.DATA gets the video uri, from the gallery too without causing any crash. Thanks in Advance..

You can use for getting absolute path from the Uri of selected file because of differences in both KitKat(API 19) and below Kitkat in android to achieve this using following code,

+ split[1];
}
// TODO handle non-primary volumes
}

else if (isDownloadsDocument(uri)) {
final String id = DocumentsContract.getDocumentId(uri);

}

selectionArgs);
}
}
