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

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

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.

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>

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