How to get Uri from Bitmap (Lollipop)

Ok, I tried this code:

public Uri getImageUri(Context inContext, Bitmap inImage) {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
        return Uri.parse(path);
    }

and looks like it can't do the job. When I log it it prints:

content://media/external/images/media/25756

which doesn't helps me because I need it for new File(Uri). Strangely, getImageUri method returns Uri, but File doesn't seem to recognize it. Anyone has method to retrieve Uri from freshly made bitmap?

P.S. As far as I read, it doesn't work since KitKat.

edit This code works and from this I want to retrieve Uri:

                croppedBitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);
                cropImageView = (CropImageView) findViewById(R.id.CropImageView);
                cropImageView.setImageBitmap(croppedBitmap);


       Button crop = ...;
       crop.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                cropContainer.setVisibility(View.GONE);
                mImageView.setVisibility(View.VISIBLE);
                Bitmap croppedImage = cropImageView.getCroppedImage();
                mImageView.setImageBitmap(croppedImage);
                paramsContener.setVisibility(View.VISIBLE);
            }
        });

Okay, I got it thanks to @CommonsWare - made something like this. Hope will help it another people as well:

public String makeBitmapPath(Bitmap bmp){
        // TimeStamp
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());

        String path = Environment.getExternalStorageDirectory().toString();
        OutputStream fOut = null;
        File file = new File(path, "Photo"+ timeStamp +".jpg"); // the File to save to
        try {
            fOut = new FileOutputStream(file);
            bmp.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
            fOut.flush();
            fOut.close(); // do not forget to close the stream

            MediaStore.Images.Media.insertImage(getContentResolver(),file.getAbsolutePath(),file.getName(),file.getName());
        } catch (IOException e){
            // whatever
        }
        return file.getPath();
    }

That would depend upon what "the job" is.

When I log it it prints: content://media/external/images/media/25756 which doesn't helps me because I need it for new File(Uri)

First, if you want to save a bitmap to a file, use a FileOutputStream rather than a ByteArrayOutputStream. Java file I/O has been around for ~20 years.

Second, if you are expecting to get file paths from a ContentProvider like MediaStore, you are going to be disappointed. You get back a Uri, like the content:// one in your question. A Uri is not a file. Use a ContentResolver and methods like openInputStream() to read in the data identified by that Uri. The concept of a "URI" representing an opaque handle to something you get via a stream has been around at least as long as has HTTP, which has been around for ~25 years.

Strangely, getImageUri method returns Uri, but File doesn't seem to recognize it.

That is because a Uri is not a file.
