Path to Assets?

I guess it depends on what you're trying to do? Based on your blocks, it seems like you might be trying to render the PDF using a webviewer. In this case, I'd do something like:

import android.util.Base64;
import com.google.appinventor.components.runtime.util.IOUtils;

// ...

InputStream in;
try {
  in = form.openAsset(filename);
  byte[] contents = IOUtils.readStream(in);
  String content64 = Base64.encodeToString(contents, Base64.NO_WRAP | Base64.URL_SAFE);
  content64 = "data:application/pdf;base64," + content64;
  // Set web viewer URL to content64
} catch (IOException e) {
  // Report error via form.dispatchErrorOccurred(...)
} finally {
  IOUtils.closeQuietly(in);
}
