wear-os - Android Wear 上长时间运行的应用

Question

Android Wear 生态系统似乎是围绕用户将与之交互然后关闭的快速任务构建的。这对大多数应用程序都很有效，但是对于一个涵盖长时间运行的任务并且在 watch 休眠时不应自动关闭的应用程序呢？

我的具体案例:Swing by Swing Golf GPS .首选操作是让应用程序保持事件状态，并在屏幕因用户操作而唤醒时显示。并且单次使用的生命周期将在 2 到 4 小时之间。

有哪些方法可以使应用程序保持在 Android Wear 设备的前端和中心位置超过一次使用时间？

所以，这是我想出的解决方案:

使用 PendingIntent 构建通知开主Activity .还将删除操作的意图传递给它，以便我们知道用户是否已关闭它。

public class SbsNotificationHelper {
    private static final String NOTIFICATION_DELETED_INTENT = "sbs.notificationDeleted";
    private static boolean _isNotificationActive = false;

    /** Public static methods */

    public static NotificationCompat.Builder buildRoundInProgressNotification(Context context) throws Throwable {
        Intent viewIntent = new Intent(context, SbsRoundActivity.class);
        PendingIntent viewPendingIntent = PendingIntent.getActivity(context, 0, viewIntent, 0);

        context.registerReceiver(_broadcastReceiver, new IntentFilter(NOTIFICATION_DELETED_INTENT));
        _isNotificationActive = true;

        Intent deleteIntent = new Intent(NOTIFICATION_DELETED_INTENT);
        PendingIntent deletePendintIntent = PendingIntent.getBroadcast(context, 0, deleteIntent, 0);

        NotificationCompat.Action action = new NotificationCompat.Action.Builder(R.drawable.circle_button, "", viewPendingIntent).build();

        Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.bottom_bg);

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.iphone_57x57)
                .setLargeIcon(bitmap)
                .setContentTitle("Golf GPS")
                .setContentText("Swing by Swing")
                .addAction(action)
                .setDeleteIntent(deletePendintIntent)
                .extend(new NotificationCompat.WearableExtender()
                        .setContentAction(0));

        return notificationBuilder;
    }

    public static boolean isNotificationActive() {
        return _isNotificationActive;
    }

    /** BroadcastReceiver */

    private static final BroadcastReceiver _broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            _isNotificationActive = false;
        }
    };

}

使用 onStop()而不是 onPause()发出通知。这样，如果您的应用程序中有多个 Activity，您可以展示它们(仅导致 onPause() 的主 Activity )。

@Override
protected void onStop() {
    super.onStop();

    int notificationId = 001;
    NotificationCompat.Builder notificationBuilder = SbsNotificationHelper.buildRoundInProgressNotification(context);

    NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(this);
    notificationManagerCompat.notify(notificationId, notificationBuilder.build());
}

还可以使用您的 WearableListenerService 中的通知如果您与掌上电脑上的应用程序通信。因此，当您的应用程序打开时，可以弹出通知并轻松访问。

@Override
public void onMessageReceived(MessageEvent messageEvent) {
    super.onMessageReceived(messageEvent);

    try {
        if (SEND_MESSAGE_PATH.equalsIgnoreCase(messageEvent.getPath())) {
            if (!SbsNotificationHelper.isNotificationActive()) {
                int notificationId = 001;
                NotificationCompat.Builder notificationBuilder = SbsNotificationHelper.buildRoundInProgressNotification(sbsApplication);

                NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(this);
                notificationManagerCompat.notify(notificationId, notificationBuilder.build());
            }
        }
    }
    catch (Throwable throwable) {
        //Handle errors
    }
}
