E-mail intent code not working

Question

when a button is clicked the method sendemail() is called. when I run the app on lollipop and when the button is clicked the app closes and no effect of intent is seen.

      protected void sendEmail() {
    EditText email = (EditText) findViewById(R.id.email);
    EditText customer = (EditText) findViewById(R.id.customer_name);
    String mail_body = "Customer name=" + customer + " Cost" + cost + "\n             thank you :)\n have a great day ahead";
    Log.i("Send email", "");
    String to = email.getText().toString();

    Intent i = new Intent(Intent.ACTION_SEND);
    i.setData(Uri.parse("mailto:"));
    i.putExtra(Intent.EXTRA_EMAIL, to);
    i.putExtra(Intent.EXTRA_SUBJECT, "ORDER SUMMARY FROM COFFEE SHOP");
    i.putExtra(Intent.EXTRA_TEXT, "this is just a test");
    i.setType("message/rfc822");

        startActivity(Intent.createChooser(i,"Send mail..."));
  }

this is error log that I got

Answer 1

Change sendEmail function to

protected void sendEmail(View v) {
    EditText email = (EditText) findViewById(R.id.email);
    EditText customer = (EditText) findViewById(R.id.customer_name);
    String mail_body = "Customer name=" + customer + " Cost" + cost + "\n             thank you :)\n have a great day ahead";
    Log.i("Send email", "");
    String to = email.getText().toString();

    Intent intent = new Intent(Intent.ACTION_SEND)
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.setType("message/rfc822");
    intent.putExtra(Intent.EXTRA_EMAIL, new String[]{to});
    intent.putExtra(Intent.EXTRA_CC, new String[]{""});
    intent.putExtra(Intent.EXTRA_SUBJECT, "ORDER SUMMARY FROM COFFEE SHOP");
    intent.putExtra(Intent.EXTRA_TEXT, "this is just a test");
    startActivity(Intent.createChooser(intent, "Send mail..."));
}

and in xml add onClick element with value "sendEmail"

android:onClick="sendEmail"

I have two suggestion :

1. change the method signature as void sendEmail(View v) in your source file.

2. edit your layout file where you have assigned the onClick attribute for the button. I can guess that in your xml you have defined the method as : android:onClick="send email" and in the src file you have defined the method with name sendEmail() .
