Question

Here is what I am doing:

In onActivityResult, I get the data in an Intent.

 Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
 startActivityForResult(intent, TAKE_PICTURE);

This code gets the image ID:

data.getData().getLastPathSegment();

Now i want to use this image ID to get byte[] imageData so I can upload the image on a server.

How do I go about it?

Answer 1

Uri selectedImageUri = data.getData();

String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(selectedImageUri, projection, null, null, null);
cursor.moveToFirst();
selectedImagePath = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA));
cursor.close();

try 
{
    File myFile = new File(selectedImagePath);
    int filelenghth=(int)myFile.length();
    byte [] mybytearray  = new byte [filelenghth];
    BufferedInputStream bis1 = new BufferedInputStream(new FileInputStream(myFile));

    bis1.read(mybytearray,0,mybytearray.length);

    dos.write(mybytearray,0,mybytearray.length);   // write the array to the data output stream
                                                   // or whatever else you want to do with it
    finish();
}
catch(Exception e)
{
    e.printStackTrace();
}
