Ambient Mode Support

Documentation: https://developer.android.com/training/wearables/apps/always-on

1. Add the WAKE_LOCK permission to your AndroidManifest.xml

	<uses-permission android:name="android.permission.WAKE_LOCK" />

2. Copy the ambient-activity.ts in the root of this project's demo app and use it to replace the default Android Activity loaded by NativeScript. NativeScript docs HERE about using a custom Android Activity.

3. Update the AndroidManifest.xml for your application to use the correct activity. Change the android:name value of the activity node to point to the same name used inside the ambient-activity.ts file inside the @JavaProxy() decorator at the top of the file.

		<activity android:name="com.nativescript.AmbientActivity" android:label="@string/title_activity_kimera" android:configChanges="keyboardHidden|orientation|screenSize" android:theme="@style/LaunchScreenTheme">

4. Update your webpack.config to include the custom Android Activity. Snippet below copied from the demo app.

// Add your custom Activities, Services and other Android app components here.
const appComponents = [
  '@nativescript/core/ui/frame',
  '@nativescript/core/ui/frame/activity',
  resolve(__dirname, 'app/ambient-activity'),
];

WearOsLayout

A base layout for Wear OS apps built with NativeScript that automatically handles calculating the inset for circle watch faces. To disable the layout from automatically adjusting the inset set disableInsetConstraint="true" on the WearOsLayout instance. The default is false and does not have to be set.

This has no effect on square watches.

    xmlns:ui="nativescript-wear-os/packages/wear-os-layout">
    <ui:WearOsLayout disableInsetConstraint="false">
      <ScrollView height="100%">
        <StackLayout>
            <Label text="Going to put a long string of text so we can fill the screen with other view components to show how this works on Circle and Square watch faces." class="c-white" textWrap="true" />
            <GridLayout rows="auto, auto, auto" columns="*, *, *">
                <Button text="Go Back" tap="navBack" class="yellowBtn" row="0" col="0" />
                <Image src="res://icon" stretch="aspectFit" row="0" col="1" />
                <Button text="Wow" class="greenBtn" row="0" col="2" />

Dialogs

This plugin uses an Android WearOS specific library SmartWearOs.

The plugin has a success dialog and failure/error dialog to present on WearOS. These mimic the behavior of the built in Confirmation Activity on WearOS. With the option of setting the time before it is dismissed/hidden from the user.

Usage

import {
  showFailure,
  showSuccess,
} from 'nativescript-wear-os/packages/dialogs';

showSuccess('Great choice! NativeScript is awesome.', 4).then(() => {
  console.log('success dialog complete.');
});
