Android Wear Tutorial

So Android Wear is going to be announced in hours at the Google I/O 2014 event.

To get started with Android Wear, follow these steps (You must sign up to the Android Wear Developer Preview, download the Android Wear Preview jar file and add the library to your project in order to continue):

1. Set up the Android Wear emulator after downloading the Android Wear System Image and related Android Wear packages from the Android SDK Manager

2. Start the emulator.

3. Download the Android Wear Preview app after opting in as a tester.

4. Use this command to connect the emulator to your phone via USB

adb -d forward tcp:5601 tcp:5601


Simple Example of Wearable Notification
1. Create a sample notification using this template. Notice that I've wrapped up notificationBuilder with WearableNotifications.Builder.

2. NotificationManagerCompat is mandatory to ensure code compatibility with lower versions of Android.

3.
NotificationCompat.Builder notificationBuilder =
        new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.ic_event)
        .setContentTitle(eventTitle)
        .setContentText(eventLocation)
        .setContentIntent(viewPendingIntent);
 Notification notification =
                new WearableNotifications.Builder(notificationBuilder)
                        .build();
// Get an instance of the NotificationManager service
NotificationManagerCompat notificationManager =
        NotificationManagerCompat.from(this);
// Build the notification and issues it with notification manager.
notificationManager.notify(notificationId, notification);



Actions
NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.ic_launcher)
                        .setContentTitle("My notification")
                        .addAction(R.drawable.ic_launcher, "Reply", pendingIntent)
                        .setContentText("Hello World!");

This reflects on the phone's status bar notification, as well as the Android Wear emulator.

Page Notifications
1. Create a second page notification
 // Create a big text style for the second page
        NotificationCompat.BigTextStyle secondPageStyle = new NotificationCompat.BigTextStyle();
        secondPageStyle.setBigContentTitle("Page 2")
                .bigText("A lot of text...");

         // Create second page notification
        Notification secondPageNotification =
                new NotificationCompat.Builder(this)
                        .setStyle(secondPageStyle)
                        .build();

Notification notification =
                new WearableNotifications.Builder(mBuilder)
                        .addPage(secondPageNotification)
                        .build();
notificationManagerCompat.notify(notificationId1, notification);

Stack Notifications

1. Set up a summary notification using WearableNotifications.Builder.

 Notification summaryNotification = new WearableNotifications.Builder(mBuilder)
                .setGroup(GROUP_KEY_SAMPLE, WearableNotifications.GROUP_ORDER_SUMMARY)
                .build();

2. Specify one or more notifications. Remember to add setGroup to the notifications.

// Create a WearablesNotification.Builder to add special functionality for wearables
        Notification notification =
                new WearableNotifications.Builder(mBuilder)
                        .setGroup(GROUP_KEY_SAMPLE)
                        //.addPage(secondPageNotification)
                        .build();

        // Use the same group as the previous notification
        Notification notif2 = new WearableNotifications.Builder(mBuilder2)
                .setGroup(GROUP_KEY_SAMPLE)
                .build();


3. Show the notification.

notificationManagerCompat.notify(notificationId1, summaryNotification);
        notificationManagerCompat.notify(notificationId2, notification);
        notificationManagerCompat.notify(notificationId3, notif2);

How to Utilize the onUpgrade method in your SqliteOpenHelper Class in Android

Based on this website's blogpost on how to non-destructively upgrade your Android app's database , I've encountered a scenario such as this: 1. I have a database which has a database version 1 which has an existing table being constructed in user's phones. 2. If I were to have a new column in my database table, if I were to deploy the new version of the app into the Google Play Store (what I mean here is an incremental install), of course I would have users bitching about force closes in my app because the database is altered, for instance by adding another column in my database table. The blogpost is helpful as he highlighted how database table alteration can be done by incrementing the database version and onUpgrade method is triggered in your SqliteOpenHelper class.
