MailComposer + HTML Content + Android

dvallen · July 16, 2020, 3:52am

Does anyone know if there is something special that I have to do (besides setting isHtml to true) to make HTML-formatted emails work properly with MailComposer under Android? Is this a very sore subject? I noticed that other queries about this were never answered & then eventually closed without resolution. Please help - my emails are somewhat dependent on an HTML table to look readable. If I need to find another way - I need to know.

Thanks!

Hi dvallen,

Did you figure this out? I am facing it & the doc only says “isHtml - Whether the body contains HTML tags so it could be formatted properly. Not working perfectly on Android.”
As far as I can see it doesn’t work at all, although ios is running fine.

Same here - iOS is fine. I am sending a plain text email from Android right now. It isn’t pretty, but it gets the job done.

I submitted a documentation bug to reflect the reality that it doesn’t work at all.

If things get less busy, I will work on a minimal example for a bug submission.

Hoping that the documentation bug will inspire someone to fix the problem

That would be swell! Thanks for taking the initiative Lili.

@dvallen, @ldwight if I understand correctly, the expo-mail-composer code basically just creates an ACTION_SENDTO intent with a “mailto:” uri.

github.com

expo/expo/blob/9cd697533d64cdee216c641b792fda7952d1afcf/packages/expo-mail-composer/android/src/main/java/expo/modules/mailcomposer/MailComposerModule.java#L59


      
              mModuleRegistry.getModule(UIManager.class).registerLifecycleEventListener(this);
            }
          }
          
          
@ExpoMethod
          public void isAvailableAsync(final Promise promise) {
            promise.resolve(true);
          }
          
          
@ExpoMethod
          public void composeAsync(ReadableArguments options, Promise promise) {
          
          
  Intent intent = new Intent(Intent.ACTION_SENDTO);
            intent.setData(Uri.parse("mailto:"));
          
          
  String[] recipients = {}, ccRecipients = {}, bccRecipients = {};
            String subject = "";
            String body = "";
            Spanned htmlBody = null;
            ArrayList<Uri> attachments = new ArrayList<>();

So it seems that expo-mail-composer doesn’t have a huge amount of control over how the intent is handled.
