Android Intent Chooser to only show E-mail option

My app integrates e-mail 开发者_如何学Gowhere 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.

To solve this issue simply follow the official documentation. The most important consideration are:

1. The flag is ACTION_SENDTO, and not ACTION_SEND.

2. The setData of method of the intent,

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

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);
    }
}

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.

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.

See this post: How to customize share intent in Android?

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!

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[]{"contact@brightsociety.com"});

    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();
    }
}

Kotlin Answer

If you need to show only email apps and then you want to open only inbox (not open new email writing), you need to do A and B:

A) Add below code in your AndroidManifest.xml file for Android 11 because of package visibility update of Android 11 :

<queries>
    <intent>
        <action android:name="android.intent.action.SENDTO" />
        <data android:scheme="mailto" />
    </intent>
    <intent>
        <action android:name="android.intent.action.CHOOSER" />
    </intent>
</queries>

B) Use below function to show email chooser:

// Show email app list.
fun showEmailAppList() {

    // Email app list.
    val emailAppLauncherIntents: MutableList<Intent?> = ArrayList()

    // Create intent which can handle only by email apps.
    val emailAppIntent = Intent(Intent.ACTION_SENDTO)
    emailAppIntent.data = Uri.parse("mailto:")

    // Find from all installed apps that can handle email intent and check version. 
    val emailApps = packageManager.queryIntentActivities(
        emailAppIntent,
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) 0 else PackageManager.MATCH_ALL
    )

    // Collect email apps and put in intent list.
    for (resolveInfo in emailApps) {
        val packageName = resolveInfo.activityInfo.packageName
        val launchIntent = packageManager.getLaunchIntentForPackage(packageName)
        emailAppLauncherIntents.add(launchIntent)
    }

    // Create chooser with created intent list to show email apps of device.
    val chooserIntent = Intent.createChooser(Intent(), "OPEN EMAIL APP")
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, emailAppLauncherIntents.toTypedArray())
    startActivity(chooserIntent)
}

Result:

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[]{"xyz@gmail.com"});
        /*if you want to attach something*/
        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();
        }
}

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=" + "sendme@me.com");  
testIntent.setData(data);  
startActivity(testIntent);  

See: http://www.gaanza.com/blog/email-client-intent-android/

After a lot of searching and testing, I finally found a perfect solution. Thanks to the Open source developer, cketti for sharing his/her concise and neat solution.

String mailto = "mailto:bob@example.org" +
    "?cc=" + "alice@example.com" +
    "&subject=" + Uri.encode(subject) +
    "&body=" + Uri.encode(bodyText);

Intent emailIntent = new Intent(Intent.ACTION_SENDTO);
emailIntent.setData(Uri.parse(mailto));

try {
  startActivity(emailIntent);
} catch (ActivityNotFoundException e) {
  //TODO: Handle case where no email app is available
}

And this is the link to his/her gist.
