TextureView Example

TextureView Example public class TextureViewActivity : Activity, TextureView.ISurfaceTextureListener { Camera _camera; TextureView _textureView; protected override void OnCreate (Bundle bundle) { base.OnCreate (bundle); _textureView = new TextureView (this); _textureView.SurfaceTextureListener = this; SetContentView (_textureView); } public void OnSurfaceTextureAvailable (Android.Graphics.SurfaceTexture surface, int width, int height) { _camera = Camera.Open (); var previewSize = _camera.GetParameters ().PreviewSize; _textureView.LayoutParameters = new FrameLayout.LayoutParams (previewSize.Width, previewSize.Height, (int)GravityFlags.Center); try { _camera.SetPreviewTexture (surface); _camera.StartPreview (); } catch (Java.IO.IOException ex) { Console.WriteLine (ex.Message); } // this is the sort of thing TextureView enables _textureView.Rotation = 45.0f; _textureView.Alpha = 0.5f; } ... }

Android Beam

Android Beam• Allows sharing data using Near Field Communication (NFC)

Android Beam• Allows sharing data using Near Field Communication (NFC)• Pushes messages when devices are close

Android Beam• Allows sharing data using Near Field Communication (NFC)• Pushes messages when devices are close• Activity on one device creates a message

Android Beam• Allows sharing data using Near Field Communication (NFC)• Pushes messages when devices are close• Activity on one device creates a message • Speciﬁes Activity that can push it

Android Beam• Allows sharing data using Near Field Communication (NFC)• Pushes messages when devices are close• Activity on one device creates a message • Speciﬁes Activity that can push it• Intent invoked on second device contains the message data

Android Beam Example

Android Beam ExampleCreate a message

Android Beam Example Create a messageprotected override void OnCreate (Bundle bundle){ ... _nfcAdapter = NfcAdapter.GetDefaultAdapter (this); _nfcAdapter.SetNdefPushMessageCallback (this, this);}public NdefMessage CreateNdefMessage (NfcEvent evt){ DateTime time = DateTime.Now; var text = ("Beam me up!nn" + "Beam Time: " + time.ToString ("HH:mm:ss")); NdefMessage msg = new NdefMessage ( new NdefRecord[]{ CreateMimeRecord ( "application/com.example.android.beam", Encoding.UTF8.GetBytes (text)) }); } }; return msg;}public NdefRecord CreateMimeRecord (String mimeType, byte [] payload){ byte [] mimeBytes = Encoding.UTF8.GetBytes (mimeType); NdefRecord mimeRecord = new NdefRecord ( NdefRecord.TnfMimeMedia, mimeBytes, new byte [0], payload); return mimeRecord;}

Android Beam Example Create a message Receive a messageprotected override void OnCreate (Bundle bundle){ ... _nfcAdapter = NfcAdapter.GetDefaultAdapter (this); _nfcAdapter.SetNdefPushMessageCallback (this, this);}public NdefMessage CreateNdefMessage (NfcEvent evt){ DateTime time = DateTime.Now; var text = ("Beam me up!nn" + "Beam Time: " + time.ToString ("HH:mm:ss")); NdefMessage msg = new NdefMessage ( new NdefRecord[]{ CreateMimeRecord ( "application/com.example.android.beam", Encoding.UTF8.GetBytes (text)) }); } }; return msg;}public NdefRecord CreateMimeRecord (String mimeType, byte [] payload){ byte [] mimeBytes = Encoding.UTF8.GetBytes (mimeType); NdefRecord mimeRecord = new NdefRecord ( NdefRecord.TnfMimeMedia, mimeBytes, new byte [0], payload); return mimeRecord;}

Android Beam Example Create a message Receive a messageprotected override void OnCreate (Bundle bundle) IParcelable [] rawMsgs = Intent.GetParcelableArrayExtra ({ NfcAdapter.ExtraNdefMessages); ... NdefMessage msg = (NdefMessage)rawMsgs [0]; _nfcAdapter = NfcAdapter.GetDefaultAdapter (this); _nfcAdapter.SetNdefPushMessageCallback (this, this);}public NdefMessage CreateNdefMessage (NfcEvent evt){ DateTime time = DateTime.Now; var text = ("Beam me up!nn" + "Beam Time: " + time.ToString ("HH:mm:ss")); NdefMessage msg = new NdefMessage ( new NdefRecord[]{ CreateMimeRecord ( "application/com.example.android.beam", Encoding.UTF8.GetBytes (text)) }); } }; return msg;}public NdefRecord CreateMimeRecord (String mimeType, byte [] payload){ byte [] mimeBytes = Encoding.UTF8.GetBytes (mimeType); NdefRecord mimeRecord = new NdefRecord ( NdefRecord.TnfMimeMedia, mimeBytes, new byte [0], payload); return mimeRecord;}
