Send Email Using Intent ( Text+Signature And Image )

Smartphones allows to access to lots of different activities as well as sending text and calling some one. These include the ability to surf the web from your handset and even sync your device with an email account to read and send messages from your mobile phone. Smartphones running Google Android are no exception. You can easily configure your smartphone to access your primary email account with commonly built in Gmail app in all the smartphones.

     So today I am going to show you how to send email from your application using intent to send it using gmail. 

Some Advantages of Email:

• Emails are easy to use. You can organize your daily correspondence, send and receive electronic messages.

• Emails are fast. They are delivered at once around the world. No other form of written communication is as fast as an email.

• The language used in emails is simple and informal.

• When you reply to an email you can attach the original message so that when you answer the recipient knows what you are talking about. This is important if you get hundreds of emails a day.

• It is possible to send automated emails with a certain text. In such a way it is possible to tell the sender that you are on vacation. These emails are called auto responders.

• Emails do not use paper. They are environment friendly and save a lot of trees from being cut down.

• Emails can also have pictures in them. You can send birthday cards or newsletters as emails.

• Products can be advertised with emails. Companies can reach a lot of people and inform them in a short time.

public class SendEmail extends Activity {
 //Create variables

 //declare views/controls

 ImageButton imBtnImage;
 EditText edTMail,edTSubject,edTMessage,edTSignature;
 @Override
 protected void onCreate(Bundle savedInstanceState) {

 }

  //get reference of the UI Controls

   @Override
   public void onClick(View v) {
    // Create instance of intent
    Intent intent = new Intent();
    // set type as image
    intent.setType("image/*");
    /*set action as ACTION_GET_CONTENT(Activity Action:
                Allow the user to select a particular kind of data and return it.)*/
    intent.setAction(Intent.ACTION_GET_CONTENT);
    /*start activity for result and pass create Chooser 
                 and set title of dialog as Select Picture*/
    startActivityForResult(Intent.createChooser(intent,
      "Select Picture"), 1);
   }
  });
  btnSendMail.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View v) {

    // Create instance of intent
    Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[]{edTMail.getText().toString()});
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, edTSubject.getText().toString());
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, edTMessage.getText().toString()+"\n\n"+edTSignature.getText().toString()); 
    // check that is user picked an image or not
    if(selectedImageUri!=null){
     emailIntent.setType("image/jpeg");
     //attach image to email by telling intent the uri of image
     emailIntent.putExtra(Intent.EXTRA_STREAM, selectedImageUri);
    }
    else emailIntent.setType("text/plain");
    /*start activity and pass create Chooser 
                  and set title of dialog as Send your email in: */
    startActivity(Intent.createChooser(emailIntent, "Send your email in:"));
   }
  });
 }
 public void onActivityResult(int requestCode, int resultCode, Intent data) {
  //RESULT_OK means that user has selected an image 
  if (resultCode == RESULT_OK) {
   //check that is the same request code that pass above 
   if (requestCode == 1) {
    //get uri from data for attachment as image
    selectedImageUri = data.getData();
    //set image on imagebutton to show the selection
    imBtnImage.setImageURI(selectedImageUri);
   }
  }
 }

}

3. note that:

• Good practice is to always check that does user want to attach image or not.
• Above I have used Intent.CreateChooser it launches dialog of options present on you android phone to let you choose the required one.
• You can choose any other email sender client as I preferred Gmail.
• Learn more uses of intent call using intent, capture image using intent, capture and crop image using intent, voice search speech recognition and web search using intent.

4. conclusion:

• Some information about how to email using intent.
• Some information about how to pick image using intent.
• know how to attach email and add signature using intent.
• Know how ACTION_SEND help to email text and attach image as well.
• know what are some of the advantages of using email.

5. About the post:

• The code seems to explain itself due to comments, but if you have any questions you can freely ask too!
•  Don’t mind to write a comment whatever you like to ask, to know,to suggest or recommend.
•  Hope you enjoy it!

3. note that:

• you can use this on button onclick,on action_down,on the fly etc.
• you can capture image by multiple ways one of them i have described above.
• you can crop image by multiple ways too but this one is using intent.
• about Camera.

• Some information about how to launch camera using intent and crop image using intent too.
• Know how to decode image from storage to bitmap from my previous post.
