Prerequisites

Visual Studio 2015 update 3

The following steps are needed to be followed in order to send the Email using Intent in Xamarin Android app.

Project

Step 4

The main.axml file will open in the main page designer.

Delete the Linear Layout and default "hello world" button by removing the coding from source panel.

Now, delete the C# button action code from MainActivity.cs page.

Step 5

Next, go to the toolbox window and scroll down until you see all the tools and controls.

Drag and drop a Button to your application.

Next, go to the properties window and edit the Button id value and Text value.

Step 7

In this step, go to the Main.axml page Source Panel. Note the Button id value.

Project

Main.axml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent">
<Button android:id="@+id/myButton" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/buttonText" />
</LinearLayout>

In this step, open the String.xml page. Go to the Solution Explorer--> Resource--> values--> String.xml.

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="buttonText">Send an email</string>
<string name="app_name">SendEmail</string>
</resources>

Step 10

Next, go to the MainActivity.cs page. Write the following code in the OnCreate() Method.

MainActivity.cs

protected override void OnCreate(Bundle bundle) {
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
Button button = FindViewById < Button > (Resource.Id.myButton);
button.Click += delegate {
var email = new Intent(Android.Content.Intent.ActionSend);
email.PutExtra(Android.Content.Intent.ExtraEmail, new string[] {
"[email protected]",
"[email protected]"
});
email.PutExtra(Android.Content.Intent.ExtraCc, new string[] {
"[email protected]"
});
email.PutExtra(Android.Content.Intent.ExtraSubject, "Hello Xamarin");
email.PutExtra(Android.Content.Intent.ExtraText, "Hello Xamarin This is My Test Mail...!");
email.SetType("message/rfc822");
StartActivity(email);
};
}

Step 11

If you have Android Virtual device, run the app on it. Else, connect your Android phone and run the app in that.

Simply, connect your phone and go to Visual Studio. The connected phone will show up in the Run menu (Ex:LENOVO A6020a40(Android 5.1-API 22)). Click the Run option.

Project

Output

After a few seconds, the app will start running on your phone.

You can tap the "Send an Email" button now.

Project

It will show To, cc, Subject and body of the message. Fill the details and tap"Send".
