 Hi all,

Sorry to bother you all. I have a proposal that I want to look someone
to help me to develop a new SMS ( short message system) in Android
platform to replace the SMS in android system. And I would like to out
source. Any one would like to take this job?

this SMS application should be:
1. SMS sending and receiving application software
2. Receive the text or MMS and store into our special design micro SD
card,and would not save in cell phone. hence, user can take this card
insert into another Android cell phone and than can see this SMS or
MMS which installed this new SMS application software.
3. Sending the text or MMS in this application software. however,
before sending, it could encrypt this text via the private key (could
be RSA 1024 bite key or 2048 ) and public key which stores in our
special design micro SD card.
4. When receiving the text or MMS, it could decrypt each time when we
read it. Same, it will get the private to decrypt this text or mms.

This project would ask for the developer who has the experience in
Smart card, PKI and SMS of Android cell phone application. And we also
need the source code.  Any one interests ?  we can discuss the
payment. please email me. m0929420...@gmail.com  Jack Hsu

PS: the special SD card is a micro SD card embeds smart card
controller and Java OS ( JCOP v2.4)

1. Detect direction of shake movement in SensorListener

Hello developers,

I have got a problem concerning the SensorListener. At the moment I
can already detect if the phone got shaken. Addtionally I now want to
detect in which direction the phone is shaken. Do you maybe know which
values I have to consider to detect this?

My code at the moment looks like this:


public class ShakeActivity extends Activity implements SensorListener
{
   // For shake motion detection.
   private SensorManager sensorMgr;
   private long lastUpdate = -1;
   private float x, y, z;
   private float last_x, last_y, last_z;
   private float raw_x, last_raw_x;
   private static final int SHAKE_THRESHOLD = 800;
   private final float shakeThreshold = 1.5f;

   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

      setContentView(R.layout.main);
      // start motion detection
      sensorMgr = (SensorManager) getSystemService(SENSOR_SERVICE);
      boolean accelSupported = sensorMgr.registerListener(this,
            SensorManager.SENSOR_ACCELEROMETER,
            SensorManager.SENSOR_DELAY_GAME);

      if (!accelSupported) {
         // on accelerometer on this device
         sensorMgr.unregisterListener(this,
               SensorManager.SENSOR_ACCELEROMETER);
      }
   }

   protected void onPause() {
      if (sensorMgr != null) {
         sensorMgr.unregisterListener(this,
               SensorManager.SENSOR_ACCELEROMETER);
         sensorMgr = null;
      }
      super.onPause();
   }

   public void onAccuracyChanged(int arg0, int arg1) {
      // TODO Auto-generated method stub
   }

   public void onSensorChanged(int sensor, float[] values) {
      Log.d("sensor", "onSensorChanged: " + sensor);
      if (sensor == SensorManager.SENSOR_ACCELEROMETER) {
         long curTime = System.currentTimeMillis();
         // only allow one update every 100ms.
         if ((curTime - lastUpdate) > 100) {
            long diffTime = (curTime - lastUpdate);
            lastUpdate = curTime;

            x = values[SensorManager.DATA_X];
            y = values[SensorManager.DATA_Y];
            z = values[SensorManager.DATA_Z];
            raw_x = SensorManager.GRAVITY_EARTH;

            float xChange = Math.abs(x - last_x);
            float speed = Math.abs(x + y + z - last_x - last_y -
last_z)
                  / diffTime * 10000;

            float deltaX = Math.abs(last_x - x);
            float deltaY = Math.abs(last_y - y);
            float deltaZ = Math.abs(last_z - y);
            float delta_raw_x = raw_x - last_raw_x;
            // Log.d("sensor", "diff: " + diffTime + " - speed: " +
speed);
            if (speed > SHAKE_THRESHOLD) {
               Log.d("sensor", "shake detected w/ speed: " + speed);
               Toast.makeText(
                     this,
                     "shake detected w/ speed: " + speed + "; accelX:
"
                           + xChange, Toast.LENGTH_SHORT).show();
               // now left,right,up,down movement has to be detected
               // somehow
            }
            last_x = x;
            last_y = y;
            last_z = z;
            last_raw_x = raw_x;
         }
      }
   }
}

2. Prevent demon form being killed, when device goes to SLEEP

Hello, I need help over here!
Hi I am developing a Linux application(deamon) written in C, for my
Android device.
I have configured my init.rc script to start the deamon when the
device is booted.
Everything works just fine when the device is booted and my demon
starts, but when the device "sleeps"(after ~30seconds)
it kills my deamon application. Do you have any Idea how to prevent my
deamon from being "killed"?
I want to make my deamon to be active all the time, just like other
processes (adb, init, .... etc)
Any idea, suggestion would help ???
