3. Nearby Message

4. What is Nearby Message?

5. Subscribe hello

7. Nearby.Messages.publish(mGoogleApiClient, mDeviceInfoMessage, PUB_SUB_STRATEGY)
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
if (status.isSuccess()) {
Log.i(TAG, "published successfully");
// Send a message to the handler to change state when done
// publishing.
sendMessageToHandler(Constants.NO_LONGER_PUBLISHING,
Constants.TTL_IN_MILLISECONDS);
} else {
Log.i(TAG, "could not publish");
handleUnsuccessfulNearbyResult(status);
}
}
});
mGoogleApiClient = new
GoogleApiClient.Builder(getActivity().getApplicationContext())
.addApi(Nearby.MESSAGES_API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();

9. mGoogleApiClient = new
GoogleApiClient.Builder(getActivity().getApplicationContext())
.addApi(Nearby.MESSAGES_API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
Nearby.Messages.subscribe(mGoogleApiClient, mMessageListener,
PUB_SUB_STRATEGY)
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
if (status.isSuccess()) {
Log.i(TAG, "subscribed successfully");
sendMessageToHandler(Constants.NO_LONGER_SUBSCRIBING,
Constants.TTL_IN_MILLISECONDS);
} else {
Log.i(TAG, "could not subscribe");
handleUnsuccessfulNearbyResult(status);
}
}
});

12. Advertising device
Nearby.Connections.startAdvertising(mGoogleApiClient, name,
appMetadata, TIMEOUT_ADVERTISE,
this).setResultCallback(new
ResultCallback<Connections.StartAdvertisingResult>() {
@Override
public void onResult(Connections.StartAdvertisingResult result) {
}
});
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<!-- Required for Nearby Connections API -->
<meta-data android:name="com.google.android.gms.nearby.connection.SERVICE_ID"
android:value="@string/service_id" />
......
</application>

13. Nearby.Connections.startDiscovery(mGoogleApiClient, serviceId, TIMEOUT_DISCOVER, this)
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
});
Discover device

14. @Override
public void onEndpointFound(final String endpointId, String deviceId, String serviceId,
final String endpointName) {
}
Nearby.Connections.sendConnectionRequest(mGoogleApiClient, myName, endpointId, myPayload,
new Connections.ConnectionResponseCallback() {
@Override
public void onConnectionResponse(String endpointId, Status status,
byte[] bytes) {
}
}, this);
找到裝置
send 連線request

15. Nearby.Connections.rejectConnectionRequest(mGoogleApiClient,
endpointId);
Nearby.Connections.acceptConnectionRequest(mGoogleApiClient, endpointId,
payload, MainActivity.this)
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
});

16. FACE API

17. ImageView myImageView = (ImageView) findViewById(R.id.imgview);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inMutable=true;
Bitmap myBitmap = BitmapFactory.decodeResource(
getApplicationContext().getResources(),
R.mipmap.img,
options);
show img
Paint myRectPaint = new Paint();
myRectPaint.setStrokeWidth(5);
myRectPaint.setColor(Color.RED);
myRectPaint.setStyle(Paint.Style.STROK
E);
init face rect
Bitmap tempBitmap =
Bitmap.createBitmap(myBitmap.getWidth
(), myBitmap.getHeight(),
Bitmap.Config.RGB_565);
Canvas tempCanvas = new
Canvas(tempBitmap);
tempCanvas.drawBitmap(myBitmap, 0, 0,
null);
create canvas , so we can draw rect on it later
FaceDetector faceDetector = new
FaceDetector.Builder(getApplicationContext()).build();
Frame frame = new
Frame.Builder().setBitmap(myBitmap).build();
SparseArray<Face> faces = faceDetector.detect(frame);
for(int i=0; i<faces.size(); i++) {
Face thisFace = faces.valueAt(i);
float x1 = thisFace.getPosition().x;
float y1 = thisFace.getPosition().y;
float x2 = x1 + thisFace.getWidth();
float y2 = y1 + thisFace.getHeight();
tempCanvas.drawRoundRect(new RectF(x1, y1, x2, y2), 2,
2, myRectPaint);
}
myImageView.setImageDrawable(new
BitmapDrawable(getResources(),tempBitmap));
use facedetector to detect face position and draw it
on canvas

21. Barcode API

22. ImageView myImageView = (ImageView) findViewById(R.id.imgview2);
Bitmap myBitmap = BitmapFactory.decodeResource(
getApplicationContext().getResources(),
R.mipmap.barcode);
myImageView.setImageBitmap(myBitmap);
BarcodeDetector detector =
new BarcodeDetector.Builder(getApplicationContext())
.setBarcodeFormats(Barcode.QR_CODE)
.build();
Frame frame = new Frame.Builder().setBitmap(myBitmap).build();
SparseArray<Barcode> barcodes = detector.detect(frame);
Barcode thisCode = barcodes.valueAt(0);
TextView txtView = (TextView) findViewById(R.id.txtContent);
txtView.setText(thisCode.rawValue);
detect QR code

30. requestUsageTimeReport(PendingIntent)
requestUsageTimeReport(PendingIntent receiver)
Ask the the system track that time the user spends in the app being launched, and report it back once done.

31. ConnectivityManager
The primary responsibilities of this class are to:
1. Monitor network connections (Wi-Fi, GPRS, UMTS, etc.)
2. Send broadcast intents when network connectivity changes
3. Attempt to "fail over" to another network when connectivity to a network is lost
4. Provide an API that allows applications to query the coarse-grained or fine-grained state of the available networks
5. Provide an API that allows applications to request and select networks for their data traffic
