Create File from Uri type android

I'm trying to select image from gallery then convert this image to File and send it via HttpPost but I'm getting always FileNotFoundException. This my Code :

Selecting the photo

public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == Activity.RESULT_OK) {
            if (requestCode == 1) {
                // currImageURI is the global variable I’m using to hold the content:
                currImageURI = data.getData();
                //Save the currImageUri (URI type) to global variable.
                photosHolder.getInstance().setOneIm(currImageURI);
            }
        }
    }

Converting the photo

                // First Try
                File myFile = new File((photosHolder.getInstance().getOneIm()).toString());
                params.put("visit_report[photos_attributes][0][file]",myFile); **The exception Raised here
// second try 
                File myFile2 = new File((photosHolder.getInstance().getOneIm()).getPath());
                params.put("visit_report[photos_attributes][1][file]",myFile2); ** Also here

And those are myFiles Value while debuging :

mFile : content:/com.android.providers.media.documents/document/image%3A19143
myFile2 : /document/image:19143

So any help ?


Update I have tried this solution also :

//get The real path from uri then save it (and then use it to create the file)
photosHolder.getInstance().setUriString(getRealPathFromURI(currImageURI));

//Convert the image URI to the direct file system path of the image file
    private String getRealPathFromURI(Uri contentURI) {
        String result = "";
        try {
        Cursor cursor = getActivity().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); // Exception raised HERE
            cursor.close(); }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }

But I got java.lang.IllegalStateException: Couldn't read row 0, col -1 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it and the idx var == to -1

Also I have tried @Praneeth Kalluri Solution but it returns always null as result.

 Uri currImageURI = data.getData();

printing currImageURI will give you some thing like this:

content://media/external/images/media/47

But what we need is the absolute path of that particular image . So we need to get real path from uri

public 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();
    }
  }
}

Now modifiy your code like

public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == Activity.RESULT_OK) {
            if (requestCode == 1) {
                // currImageURI is the global variable I’m using to hold the content:
                currImageURI = data.getData();
                //Save the currImageUri (URI type) to global variable.
                photosHolder.getInstance().setOneIm(getRealPathFromURI(getActivity(),currImageURI));
            }
        }
    }

public 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();
    }
  }
}
