Android Studio mailto Intent doesn't show subject and mail body

Question

I'm trying to send an e-mail from my Android App. With the click on a button, gmail should open and show a new email with my previously defined recipient, subject and email body. So far I've tried sending the Intent.ACTION_VIEW as well as Intent.ACTION_SENDTO. Both show my draft with the recipient only. Both subject and message are being opressed. Weird thing is when using the emulator, it works just fine. Also was trying to lock at the android errorlog. Seems like i don't have permission. Is it really a permission problem or could it be something else? I'd really appreciate any help cheers

Here is my code:

• sending email via ACTION_VIEW

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("mailto:" + to));
intent.putExtra(intent.EXTRA_SUBJECT, subject);
intent.putExtra(intent.EXTRA_TEXT, message);
mainActivity.startActivity(intent);

• sending email via ACTION_SENDTO

Intent email = new Intent(Intent.ACTION_SENDTO);
email.setType("message/rfc822");
email.putExtra(Intent.EXTRA_EMAIL, new String[]{to});
email.putExtra(Intent.EXTRA_SUBJECT, subject);
email.putExtra(Intent.EXTRA_TEXT, message);
mainActivity.startActivity(Intent.createChooser(email, "Choose an Email client :"));

• error message from logcat

Answer 1

I think we had the same issue. Android API 29 introduced some improvements about sending data to other apps. See more details here: Sending simple data to other apps

Here is the solution that works for me.

Intent selectorIntent = new Intent(Intent.ACTION_SENDTO);
selectorIntent.setData(Uri.parse("mailto:"));

final Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"[email protected]"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "The subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "The email body");
emailIntent.setSelector( selectorIntent );

activity.startActivity(Intent.createChooser(emailIntent, "Send email..."));

In few words, with this you are asking for the Android standard app chooser and, in addition, you specify that you want to send an email. So, as result, email clients will appear only. If user has one email client installed only, the intent will redirect to it instantly.

Hope this helps you too.

Answer 2

try out this code, it worked for me.

Intent intent = new Intent(Intent.ACTION_SENDTO);
intent.setData(Uri.parse("mailto:")); // only email apps should handle this
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{email});
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject here");
intent.putExtra(Intent.EXTRA_TEXT,"Body Here");
if (intent.resolveActivity(getPackageManager()) != null) {
    startActivity(intent);
}

also add intent filter in android manifest.

<activity ...>
<intent-filter>
    <action android:name="android.intent.action.SENDTO" />
    <data android:scheme="mailto" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

Answer 3

In order to get it to work on Samsung and Pixel devices, we had to add the parameters on both the url and the extras

val email = "[email protected]"
val subject = "xxxx"
val body = "xxxx"

val selectorIntent = Intent(Intent.ACTION_SENDTO)
val urlString = "mailto:" + Uri.encode(email) + "?subject=" + Uri.encode(subject) + "&body=" + Uri.encode(body)
selectorIntent.data = Uri.parse(urlString)

val emailIntent = Intent(Intent.ACTION_SEND)
emailIntent.putExtra(Intent.EXTRA_EMAIL, arrayOf(email))
emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject)
emailIntent.putExtra(Intent.EXTRA_TEXT, body)
emailIntent.selector = selectorIntent

startActivity(Intent.createChooser(emailIntent, "Send email"))

Answer 4

Our old code for emails stopped working some days ago.

It was the following:

public static void shareTextToEmail(Context context, String[] email, String subject, String text)
    Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:" + TextUtils.join(",", email)));
    emailIntent.putExtra(Intent.EXTRA_EMAIL, email);
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
    emailIntent.putExtra(Intent.EXTRA_TEXT, text);
    try {
        context.startActivity(Intent.createChooser(emailIntent, context.getString(R.string.share_email_title)));
    } catch (android.content.ActivityNotFoundException e) {
        Toast.makeText(context, context.getString(R.string.share_no_intent_handler_found), Toast.LENGTH_SHORT).show();
    }
}

I've adopted it according to the Zak.Antonio answer:

public static void shareTextToEmail(Context context, String[] email, String subject, String text)
    Intent selectorIntent = new Intent(Intent.ACTION_SENDTO);
    selectorIntent.setData(Uri.parse("mailto:"));

    final Intent emailIntent = new Intent(Intent.ACTION_SEND);
    emailIntent.putExtra(Intent.EXTRA_EMAIL, email);
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
    emailIntent.putExtra(Intent.EXTRA_TEXT, text);
    emailIntent.setSelector(selectorIntent);

    try {
        context.startActivity(Intent.createChooser(emailIntent, context.getString(R.string.share_email_title)));
    } catch (android.content.ActivityNotFoundException e) {
        Toast.makeText(context, context.getString(R.string.share_no_intent_handler_found), Toast.LENGTH_SHORT).show();
    }
}

The key points are:

• Replace Intent.ACTION_SENDTO with Intent.ACTION_SEND in emailIntent
• Move Intent.ACTION_SENDTO to a selectorIntent
• Do not put emails in intent data, put them only in extras at Intent.EXTRA_EMAIL

Answer 5

This answer worked for me using parsing using Uri

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:?subject=" + subject + "&to=" + to));
 context.startActivity(emailIntent);

Answer 6

If your app targets Android 11 (API level 30) or higher then we require to add :

• <queries> element in the app's manifest file (Because of Package visibility changes in Android 11)

Set the queries in the Manifest file like this:

<manifest package="com.example.app">
    ...
    <!-- Package visibility -->
    <queries>
        <!-- Mail -->
        <intent>
            <action android:name="android.intent.action.SENDTO" />
            <data android:scheme="mailto" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent>
    </queries>
    ...
</manifest>

Kotlin method to open Email apps :

fun composeEmail(recipient: String, subject: String, body: String) {
    val selectorIntent = Intent(Intent.ACTION_SENDTO).apply{
        data = Uri.parse("mailto:") // only email apps should handle this
    }
    val emailIntent = Intent(Intent.ACTION_SEND).apply {
        putExtra(Intent.EXTRA_EMAIL, arrayOf(recipient))
        putExtra(Intent.EXTRA_SUBJECT, subject)
        putExtra(Intent.EXTRA_TEXT, body)
        selector = selectorIntent
    }
    if (emailIntent.resolveActivity(packageManager) != null) {
        startActivity(emailIntent)
    }
}
