Resolving the path while recieving data from an external app

Question

i am implementing the functionality to save file in my app which is being sent by some exteral application.

i have provided support for single and mulitple files. Provided handling for all kind of files.

But i am not able to handle the following scenario.

I view a file from an email client -> View it in QuickOffice -> Click on send -> Choose my app->Then click on save in my app.

In that i get the path in following wrapped in the exception

java.io.FileNotFoundException: /file:/data/data/com.qo.android.sp.oem/files/temp/Error.log: open failed: ENOENT (No such file or directory)

I have seen this post which is quite useful for handling uri which has content scheme Get filename and path from URI from mediastore

Below is my code

Uri uri = (Uri) iterator.next();
                            if ("content".equals(uri.getScheme())) {
                                filePath = getFilePathFromContentUri(uri, hostAcitvity.getContentResolver());
                            }
                            else {
                                filePath = uri.getPath();
                            }
                            fileName = uri.getLastPathSegment();
                            fileSize = hostAcitvity.getContentResolver().openInputStream(uri).available();

Code for getFilePathFromContentUri

private String getFilePathFromContentUri(Uri selectedVideoUri, ContentResolver contentResolver)
    {
        String filePath;
        String[] filePathColumn = { MediaColumns.DATA };

        Cursor cursor = contentResolver.query(selectedVideoUri, filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        filePath = cursor.getString(columnIndex);
        cursor.close();
        return filePath;
    }

Then i wrap the path in a FileInputStream which is throwing the above exception Not able to resolve the file path properly. Is this the correct way of finding the path ?

That never worked reliably and will work even less reliably in the future.

No, because there is no requirement that every Uri map to a path on a filesystem that you can access.

Use getInputStream() on ContentResolver to get an InputStream on the Uri, and consume the data that way.
