Android - Obtain Uri to image on sdcard

Question

I have the absolute path to a .jpg in the gallery. How can I obtain a 'content://' Uri to this image, so that I can use this Uri like this:

Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

I need to launch this intent so I can view the image. How do I obtain the uri, when I have got only the absolute path to the image?

Answer 1

First you need to read the file from your SDCard.

See:

reading a specific file from sdcard in android

http://developer.android.com/reference/java/io/File.html

File dir = Environment.getExternalStorageDirectory();
File yourFile = new File(dir, "path/to/the/file/inside/the/sdcard.ext");

Then call the File.toUri() method to retreive the URI from the file.

Intent intent = new Intent(Intent.ACTION_VIEW, yourFile.toURI());
startActivity(intent);
