Java Question

Convert Uri to String and String to Uri

I'm developing some Application which allows select image from SD Card, save it into database and set this value for ImageView. I need to know way for converting uri to string and string to uri. Now I used getEncodedPath() method of Uri, but, for example, this code doesn't work:

ImageView iv=(ImageView)findViewById(R.id.imageView1);
Uri uri=Uri.parse("/external/images/media/470939");
Log.e("uri1", uri.toString());
iv.setImageURI(uri);


Therefore I don't know how I can save Uri into database and create a new Uri from saved value. Please, help me to fix it.

Answer

I need to know way for converting uri to string and string to uri.

Use toString() to convert a Uri to a String. Use Uri.parse() to convert a String to a Uri.

this code doesn't work

That is not a valid string representation of a Uri. A Uri has a scheme, and "/external/images/media/470939" does not have a scheme.
