i am trying to parse uri for the file to open from Storage Access Framework.

how can i get the path and open it using File Library..

protected void onActivityResult(int requestCode, int resultCode, Intent data){
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == OPEN_REQUEST_CODE && resultCode == Activity.RESULT_OK) {

        if (data != null) {
            uri = data.getData();
            EditText FileLocation = (EditText) findViewById(R.id.FileUrl);
            File file=new File(uri.getPath());

            if(file.exists()){

            }else{

            }

        }
    }

i m not able to access the file..

    yet another ... **Uri is not a file path** ... also documentation of Storage Access Framework is clear how to open a file – Selvin Jun 16 '17 at 10:34

Use below code to get path and file name

 private static final int FILE_SELECT_CODE = 0;

    String mediaPath;

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {
            case FILE_SELECT_CODE:
                if (resultCode == RESULT_OK) {
                    // Get the Uri of the selected file
                    Uri uri = data.getData();
                    Log.d("=========>>>>>", "File Uri: " + uri.toString());
                    // Get the path
                    try {
                        mediaPath = getPath(this, uri);

                        Log.d("==============>>>>mpp","test"+mediaPath);
                        //createByteArray(path);
                        getFileName(uri);

                    } catch (URISyntaxException e) {
                        e.printStackTrace();
                    }
                    // Get the file instance
                    // File file = new File(path);
                    // Initiate the upload
                }
                break;
        }
        super.onActivityResult(requestCode, resultCode, data);
    }



public String getFileName(Uri uri) {
        String result = null;

            int cut = result.lastIndexOf('/');
            if (cut != -1) {
                result = result.substring(cut + 1);

    No, it is not correct ... it is also a [copy of someone else's answer](https://stackoverflow.com/questions/19985286/convert-content-uri-to-actual-path-in-android-4-4#answer-27271131) which basically is a stealing – Selvin Jun 16 '17 at 11:01
