Android Intent Chooser to only show E-mail option

问题:

My app integrates e-mail where the user can submit a bug report, feedback, etc. from the app directly. I'm using the application/octet-stream as the SetType for the Intent. When you go to submit the e-mail you get the content chooser and it shows various items from Evernote, Facebook, E-mail, etc.

How can I get this chooser to only show E-mail so as not to confuse the user with all these other items that fit the content chooser type?

Thank you.

I am presuming that you are using the ACTION_SEND Intent action, since you did not bother to actually state what you're using, but you agreed with @Aleadam's comment.

I'm using the application/octet-stream as the SetType for the Intent.

Nothing in that sentence limits things to email.

ACTION_SEND is a generic Intent action that can be supported by any application that wants to. All you do is indicate what data you are sharing and the MIME type of that data -- from there, it is up to the user to choose from available activities.

As @Jasoon indicates, you can try message/rfc822 as the MIME type. However, that is not indicating "only offer email clients" -- it indicates "offer anything that supports message/rfc822 data". That could readily include some application that are not email clients.

If you specifically want to send something by email, integrate JavaMail into your app, or write an email forwarding script on your Web server and invoke it, or something. If you use ACTION_SEND, you are implicitly stating that it is what the user wants that matters, and you want the user to be able to send such-and-so data by whatever means the user chooses.

I solved this issue with simple lines of code as in the android documentation explain (https://developer.android.com/guide/components/intents-common.html#Email)

The most important is the flag: it is ACTION_SENDTO, and not ACTION_SEND

The other important line is

intent.setData(Uri.parse("mailto:")); ***// only email apps should handle this***

By the way, if you send an empty Extra, the if() at the end won't work and the app won't launch the email client.

This works for me. According to Android documentation. If you want to ensure that your intent is handled only by an email app (and not other text messaging or social apps), then use the ACTION_SENDTO action and include the "mailto:" data scheme. For example:

public void composeEmail(String[] addresses, String subject) {
    Intent intent = new Intent(Intent.ACTION_SENDTO);
    intent.setData(Uri.parse("mailto:")); // only email apps should handle this
    intent.putExtra(Intent.EXTRA_EMAIL, addresses);
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent);
    }
}

Just struggled with this problem while implementing a Magic Link feature, a chooser intent for all installed email apps:

Chooser Intent Screenshot

private void openEmailApp() {
  List<Intent> emailAppLauncherIntents = new ArrayList<>();

  //Intent that only email apps can handle:
  Intent emailAppIntent = new Intent(Intent.ACTION_SENDTO);
  emailAppIntent.setData(Uri.parse("mailto:"));
  emailAppIntent.putExtra(Intent.EXTRA_EMAIL, "");
  emailAppIntent.putExtra(Intent.EXTRA_SUBJECT, "");

  PackageManager packageManager = getPackageManager();

  //All installed apps that can handle email intent:
  List<ResolveInfo> emailApps = packageManager.queryIntentActivities(emailAppIntent, PackageManager.MATCH_ALL);

  for (ResolveInfo resolveInfo : emailApps) {
    String packageName = resolveInfo.activityInfo.packageName;
    Intent launchIntent = packageManager.getLaunchIntentForPackage(packageName);
    emailAppLauncherIntents.add(launchIntent);
  }

  //Create chooser
  Intent chooserIntent = Intent.createChooser(new Intent(), "Select email app:");
  chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, emailAppLauncherIntents.toArray(new Parcelable[emailAppLauncherIntents.size()]));
  startActivity(chooserIntent);
}

There is a way more generic to do that, working with any MIME type.

It works on all devices. It will show only Email Apps

public static void shareViaMail(Activity activity, String title, String body, String filePath) {

    Uri URI = Uri.parse("file://" + filePath);
    final Intent emailIntent = new Intent(Intent.ACTION_VIEW);

    emailIntent.setData(Uri.parse("mailto:"));

    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{"[e-mail]"});

    if (URI != null) {
        emailIntent.putExtra(Intent.EXTRA_STREAM, URI);
    }
    try {
        activity.startActivity(emailIntent);
    } catch (Exception e) {
        ((BaseActivity) activity).showToast("Gmail App is not installed");
        e.printStackTrace();
    }
}

It is possible to limit the choices of an intent chooser to just a few options. The code in the answer to this question is a good example. In essence, you would have to create a List of LabeledIntents to provide to the intent chooser, that will then include it in its list. Note that this solution works not on exclusion (certain apps are excluded while the rest remain) but instead you have to pick which apps to display. Hope it helps!

Solution is very simple:

Intent testIntent = new Intent(Intent.ACTION_VIEW);  
Uri data = Uri.parse("mailto:?subject=" + "blah blah subject" + "&body=" + "blah blah body" + "&to=" + "[e-mail]");  
testIntent.setData(data);  
startActivity(testIntent);
