Only Email apps to resolve an Intent

Question

I have a problem .. I want only email activities to resolve intent ACTION.SEND but beside email I get other apps as well (e.g TubeMate) even though I have set the mime type

Answer 1

Here is how I send email with attachments (proved to work with attachments of various MIME types, even in the same email) and only allow email apps (it also has a solution for cases that no app support "mailto"). At first, we try and get activities that support mailto: format. If none are found then we get all activities that supports the message/rfc822 MIME type. We select the default app (if there is a default) or allow the user to select from the available apps. If no app supports mailto: and message/rfc822, then we use the default chooser.

public static void sendEmail(final Context p_context, final String p_subject, final String p_body, final ArrayList p_attachments)
{
    try
    {
        PackageManager pm = p_context.getPackageManager();
        ResolveInfo selectedEmailActivity = null;

        Intent emailDummyIntent = new Intent(Intent.ACTION_SENDTO);
        emailDummyIntent.setData(Uri.parse("mailto:some@emaildomain.com"));

        List emailActivities = pm.queryIntentActivities(emailDummyIntent, 0);

        if (null == emailActivities || emailActivities.size() == 0)
        {
            Intent emailDummyIntentRFC822 = new Intent(Intent.ACTION_SEND_MULTIPLE);
            emailDummyIntentRFC822.setType("message/rfc822");

            emailActivities = pm.queryIntentActivities(emailDummyIntentRFC822, 0);
        }

        if (null != emailActivities)
        {
            if (emailActivities.size() == 1)
            {
                selectedEmailActivity = emailActivities.get(0);
            }
            else
            {
                for (ResolveInfo currAvailableEmailActivity : emailActivities)
                {
                    if (true == currAvailableEmailActivity.isDefault)
                    {
                        selectedEmailActivity = currAvailableEmailActivity;
                    }
                }
            }

            if (null != selectedEmailActivity)
            {
                // Send email using the only/default email activity
                sendEmailUsingSelectedEmailApp(p_context, p_subject, p_body, p_attachments, selectedEmailActivity);
            }
            else
            {
                final List emailActivitiesForDialog = emailActivities;

                String[] availableEmailAppsName = new String[emailActivitiesForDialog.size()];
                for (int i = 0; i < emailActivitiesForDialog.size(); i++)
                {
                    availableEmailAppsName[i] = emailActivitiesForDialog.get(i).activityInfo.applicationInfo.loadLabel(pm).toString();
                }
