Your first Wear app

Follow these steps to create your first Xamarin.Android Wear app:

1. Create new Android project

Create a new Android Wear Application:

This template automatically includes the Xamarin Android Wearable Library NuGet (and dependencies) so you'll have access to Wear-specific controls.

If you don't see the Wear template, double-check you've installed a supported Android SDK (API 20 or 21).

2. Choose the correct Target Framework

Ensure the target framework is set to Android 5.0 (Lollipop) (or the earlier 4.4.87 with Wear support):

3. Edit the Main.axml layout

Configure the layout to contain a TextView and a Button for the sample:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
  <ScrollView
    android:id="@+id/scroll"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:background="#000000"
    android:fillViewport="true">
    <LinearLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:orientation="vertical">
      <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="2dp"
        android:text="Main Activity"
        android:textSize="36sp"
        android:textColor="#006600" />
      <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="2dp"
        android:textColor="#cccccc"
        android:id="@+id/result" />
      <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:onClick="showNotification"
        android:text="Click Me!"
        android:id="@+id/click_button" />
    </LinearLayout>
  </ScrollView>
</FrameLayout>

4. Edit the MainActivity.cs source

Add the code to increment a counter and display it whenever the button is clicked:

[Activity (Label = "WearTest", MainLauncher = true, Icon = "@drawable/icon")]
public class MainActivity : Activity
{
  int count = 1;

  protected override void OnCreate (Bundle bundle)
  {
    base.OnCreate (bundle);

    SetContentView (Resource.Layout.Main);

    Button button = FindViewById<Button> (Resource.Id.click_button);
    TextView text = FindViewById<TextView> (Resource.Id.result);

    button.Click += delegate {
      text.Text = string.Format ("{0} clicks!", count++);
    };
  }
}
