Error: Install Failure: No manifest. Invalid package.Install Failure: No manifest

Question

Hi I am just beginning with Roku development. I downloaded the sdk and have been trying to run an hello world application. I have a source folder and a manifest file. But I still keep getting the following error:

Error: Install Failure: No manifest. Invalid package.Install Failure: No manifest.

Here is the code for hello world:

sub Main()
  ' create our screen
  screen = CreateObject("roPosterScreen") 

  ' setup a message port so we can receive event information
  port = CreateObject("roMessagePort")
  screen.SetMessagePort(port)

  ' change the screen's message text
  screen.ShowMessage("Hello World!")
  screen.Show()

  ' start our event loop
  while true
    msg = Wait(0, port) ' wait for an event

    if type(msg) = "roPosterScreenEvent"
      ' we got a poster screen event
      if msg.isScreenClosed()
        ' the user closed the screen
        exit while
      end if
    end if
  end while

  screen.Close()
  ' any time all screens in a channel are closed, the channel will exit
end sub

When I upload the examples that came with the sdk it works fine But when I try to replace the example app's Main function's code with above code I get the error specified above.

I have been looking all over the internet about this but did not help much. Any suggestions would be really appreciated.

This sounds like your files are not zipped "correctly" in the package. Make sure the manifest file is at top level in the zip and not in a subdirectory.

It's a common mistake people pointing at the project directory - right-click and zip it like so - but that includes the root directory name in the paths too. Get inside the project dir, select all files and source directory and zip this way instead.
