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();
