How to Open Email Program via Intents (But Only an Email Program)

How to open Email program via Intents (but only an Email program)

Changing the MIME type is the answer, this is what I did in my app to change the same behavior. I used intent.setType("message/rfc822");

Open Email App only through intent in Android Studio

Use this code to open default Mail Application :

try {
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_APP_EMAIL);
    this.startActivity(intent);
} catch (android.content.ActivityNotFoundException e) {
    Toast.makeText(Dashboard.this, "There is no email client installed.", Toast.LENGTH_SHORT).show();
}

Opening email client via Intent (but not to send a message)

I think you should replace Intent.ACTION_SEND to Intent.ACTION_VIEW,
i am sure this will work as this will prompt with list of application which support MIME type "message/rfc822" so it will include your default email client in your device other than gmail app.

How about this code:

final Intent emailLauncher = new Intent(Intent.ACTION_VIEW);
emailLauncher.setType("message/rfc822");
try{
       startActivity(emailLauncher);
}catch(ActivityNotFoundException e){

}

Open mail app via intent doesn't open chooser

use the following snippet to open to outlook directly from a different app

context.startActivity(
            Intent().apply {
                action = Intent.ACTION_MAIN
                addCategory(Intent.CATEGORY_LAUNCHER)
                component = ComponentName(
                   outlookLaunchIntent?.component?.packageName, 
                   outlookLaunchIntent?.component?.className
                )
                setPackage(outlookLaunchIntent.package)
            }
        )

com.microsoft.office.outlook is the package name for outlook

For sending it to all email clients use a uri like this

Intent intent = new Intent(Intent.ACTION_VIEW);
Uri data = Uri.parse("mailto:?subject=" + subject + "&body=" + body);
intent.setData(data);
startActivity(intent);

Ref:How to open Email program via Intents (but only an Email program)

Opening an email client on clicking a button

Goes like this:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("plain/text");
intent.putExtra(Intent.EXTRA_EMAIL, new String[] { "some@email.address" });
intent.putExtra(Intent.EXTRA_SUBJECT, "subject");
intent.putExtra(Intent.EXTRA_TEXT, "mail body");
startActivity(Intent.createChooser(intent, ""));

Alternatively, you could use IntentFactory.getSendEmailIntent(String mailTo, String mailCC,
String subject, CharSequence body, File attachment).

Android intent not showing only email clients

when you will change your intent.setType like below you will get

intent.setType("text/plain");

Use

android.content.Intent.ACTION_SENDTO

(new Intent(Intent.ACTION_SENDTO);) to get only the list of e-mail clients, with no facebook or other apps. Just the email clients.

I wouldn't suggest you get directly to the email app. Let the user choose his favorite email app. Don't constrain him.

If you use ACTION_SENDTO, putExtra does not work to add subject and text to the intent. Use Uri to add the subject and body text.

We can use message/rfc822 instead of "text/plain" 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.

message/rfc822 supports MIME Types of .mhtml, .mht, .mime

EDIT

 Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:someone@example.com"));
 intent.putExtra("subject", "my subject");
 intent.putExtra("body", "my message");
 startActivity(intent);

its working ...
