OkWear

This is library to easily use connection between android wear and handheld device.

Usage

Example

Send

static final String PATH = "/path"
static final String MESSAGE = "hello"

OkWear ok = new OkWear(context);

// unused callback listener
ok.sendMessageAll(MESSAGE, PATH);

// use callback listener
ok.sendMessageAll(MESSAGE, PATH, new SendResultListener<MessageApi.SendMessageResult>() {
  @Override
  public void onResult(MessageApi.SendMessageResult result) {
   Log.v(TAG, "Status: " + result.getStatus());
  }
 });

You can easily setup to use Payload class.

OkWear ok = new OkWear(context);

Payload payload =
 new Payload.Builder(PATH)
    .addPayload("key1", 0)
    .addPayload("key2", "hello")
    .build();

// unused callback listener
ok.syncData(payload);

// use callback listener
ok.syncData(payload, new SendResultListener<DataApi.DataItemResult>() {
   @Override
   public void onResult(DataApi.DataItemResult result) {
    Log.v(TAG, "Status: " + result.getStatus());
   }
  });

Receive

OkWear ok = new OkWear(this);
ok.registReceiver(this);

implements callback listener(WearReceiveListener) on your class.

@Override
public void onReceiveMessage(MessageEvent messageEvent) {
 if (messageEvent.getPath().equals(PATH)) {
  final String messagePayload = new String(messageEvent.getData());
  Log.v(TAG, messagePayload);
 }
}

@Override
public void onReceiveDataApi(DataEventBuffer dataEventBuffer) {
 for (DataEvent event : dataEventBuffer) {
  final DataMap dataMap = DataMap.fromByteArray(event.getDataItem().getData());
  final int data1 = dataMap.getInt("key1");
  final String data2 = dataMap.getString("key2");
  Log.v(TAG, "data(int): " + data1);
  Log.v(TAG, "data(string): " + data2);
 }
}

Tips

You can easily create payloads using these util classes.

  • Payload Payload is created by key value pairs.
Support values
ArrayList<Integer> Asset Bitmap boolean byte int
ArrayList<String> byte[] DataMap double float float[]
ArrayList<DataMap> long long[] String String[]
Payload payload =
 new Payload.Builder("path")
    .addPayload("key1", 0)
    .addPayload("key2", "hello")
    .build();
Support values
boolean long int short
double float String char
byte[] payload = ParseByteArray.fromString("hello");

Setup

Gradle

Add the dependency in your build.gradle

buildscript {
 repositories {
  jcenter()
 }
}

dependencies {
 compile 'com.github.aakira:okwear:1.0.2'
}

Lifecycle

Activty, Fragment or Service You have to call connect() and disconnect() methods when onResume() and onPause() occur in your lifecycle

OkWear mOkWear;

@Override
protected void onResume() {
 super.onResume();
 mOkWear.connect();
}

@Override
protected void onPause() {
 super.onPause();
 mOkWear.disconnect();
}
