Hi all I want to get from an Android Uri (of the kind returned by onActivityResult) to a simple byte array, in order to upload a file as part of a multipart message. Can anyone provide an example of how to get from a Uri to a byte[] array?
My current code (below) is almost there, but falls down because I can't work out the LENGTH_OF_FILE from an InputStream. I'd have the same problem using ByteArrayOutputStream. I've been looking at the docs on Content Providers http://developer.android.com/guide/topics/providers/content-providers.html and wondering if getBlob() is the method I need, but it says it only applies to small amounts of data (<50KB) and I need to handle larger files. thanks! Current code (doesn't work): public static byte[] getBytesFromFile(ContentResolver cR, String fileUriString) throws IOException { Uri tempuri = Uri.parse(fileUriString); InputStream is = cR.openInputStream(tempuri); byte[] b3 = new byte[LENGTH_OF_FILE]; is.read(b3); -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
