I know how to create a EditText class but I do not know the operation post to the gmail. Thank you.

In Android, you can use Intent.ACTION_SEND to call an existing email client to send an Email.
Intent email = new Intent(Intent.ACTION_SEND);
email.putExtra(Intent.EXTRA_EMAIL, new String[]{"put_your_mail#gmail.com"});
email.putExtra(Intent.EXTRA_SUBJECT, "subject");
email.putExtra(Intent.EXTRA_TEXT, "message");
email.setType("message/rfc822");
startActivity(Intent.createChooser(email, "Choose an Email client :"));

Standard way to do this is using the ACTION_SEND intent
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, "emailaddress#emailaddress.com");
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
intent.putExtra(Intent.EXTRA_TEXT, "I'm email body.");
startActivity(Intent.createChooser(intent, "Send Email"));
If you want to send the mail in background without opening another app check this answer https://stackoverflow.com/a/2033124/2761055

Here, you have information how to do that in background with PHP file on your server.
But in my opinion, this method is deprecated.
Look also here. This code will start new intent with email.

Android intent not showing only email clients

So I'm trying to launch a prepopulated email client with data. The content gets populated fine, however my problem is that when launching the intent, I wanted it to only show email clients to select from.
Instead, it shows Gmail, Adding to EverNote, Android Beam, Bluetooth, and some others.
I don't know if its an issue with lollipop that broke this functionality or not, as one of my managers sent me code that worked fine for him a few years ago.
My code is:
private void openEmailClient(){
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("message/rfc822");
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{getResources().getString(R.string.contact_feedback_email_address)});
intent.putExtra(Intent.EXTRA_SUBJECT, getResources().getString(R.string.contact_feedback_email_subject_android));
try{
startActivity(Intent.createChooser(intent,intentEmailString));
} catch(android.content.ActivityNotFoundException ex){
Log.e(EMAIL_FAIL_TAG, EMAIL_FAIL);
ex.printStackTrace();
}
}

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 ...

So I solved it. Not ideally but it works better than anything else I have tried.
I followed the google docs on doing it, which says to do this:
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);
}
}
and it now works.
This just finds a default app for handling mail. I'm not sure how it decides, but in my case it opened GMail. On a device without GMail installed, such as the Galaxy S5, it opened their mail client and prompted the user to set up email.
Doesn't give choice of app but it works

Try like this it working fine for me...
Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:abc#gmail.com"));
intent.putExtra(Intent.EXTRA_SUBJECT, "Test App");
intent.putExtra(Intent.EXTRA_TEXT, "Email Body");
startActivity(intent);
Note: it only work if you have email address.

Email intent always launch gmail by default

String body="message";
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Check out this book I am reading");
emailIntent.setType("plain/text");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, body);
startActivity(Intent.createChooser(emailIntent, "Send email..."));
No matter what I do (removing all gmail accounts and signin a hotmail account with mail app), this code launches Gmail by default and do not show or let me choose my universal mail app.
Consequently, there is no way to let user send email via hotmail or other mail provider.
update:
Actually this is the best piece of code I ever come across, it presents you directly with an app chooser where only mail client are present. The answer below will give you a huge list of apps to choose from that are irrelevant.
String mailTo="";
Intent email_intent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto",mailTo, null));
email_intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject text here");
email_intent.putExtra(android.content.Intent.EXTRA_TEXT,"Body text here");
startActivity(Intent.createChooser(email_intent, "Send email..."));

Try using the correct MIME type (text/plain) instead of an invalid MIME type (plain/text).

Sending an email via an intent

I am currently working on an android project and I am adding a preference to be able to send me an email. I am using the ACTION_SENDTO intent to send the email but its coming back and says No apps can perform this action.
Below is the code I am using
Intent intent = new Intent(Intent.ACTION_SENDTO);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, "someone#example.com");
intent.putExtra(Intent.EXTRA_SUBJECT, "Check out this android app");
intent.putExtra(Intent.EXTRA_TEXT, "Check out this new app in the Google Play Store. Its from Boardies IT Solutions and is called Boardies Password Manager. You can find it at https://play.google.com/store/apps/details?id=com.BoardiesITSolutions.PasswordManager");
startActivity(Intent.createChooser(intent, "Send Email"));
Thanks for any help you can provide

You need to add the following
intent.setData(Uri.parse("mailto:" + "email#bla.com")); // leave
blank if not specificity

I think you should replace Intent.ACTION_SENDTO to Intent.ACTION_SEND,
Hope this will work for you.
How about this code:
final Intent emailLauncher = new Intent(Intent.ACTION_SEND);
emailLauncher.setType("message/rfc822");
emailLauncher.putExtra(Intent.EXTRA_EMAIL, "username#domain.com");
emailLauncher.putExtra(Intent.EXTRA_SUBJECT, "check this subject line");
emailLauncher.putExtra(Intent.EXTRA_TEXT, "hey check this message body!");
try{
startActivity(emailLauncher);
}catch(ActivityNotFoundException e){
}

Getting the recepient count from email sent in Android

I'm launching the email program in Android from my app, using the following code...
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("message/rfc822");
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Test subject");
sendIntent.putExtra(Intent.EXTRA_TEXT, "Hello World!");
startActivityForResult(Intent.createChooser(sendIntent, "Select email application."), INTENT_REQUEST_SEND_EMAIL);
In the called OnActivityResult(), is it possible to get the number of recepients the user has chosen to send the email to?
Thanks,
Rajath

That action does not support startActivityForResult(), sorry.
