Hi
I have not tried any cross platforms as yet.
I think the only way forward is separate projects each in there own language...........

Hi Mathy,
Windows CE is a large set of software components interfacing to a large set of hardwware components. The Platform Builder[^] application produces OSes including selected software components interfacing selected hardware components.
Windows Mobile is a hardware and software specification based on specified Windows CE components.
cheers,

That's rather a lot of questions, perhaps it would be better if you explained which part of this program you are able to write for yourself. And please don't be surprised or offended if nobody offers to write it all for you.
Just say 'NO' to evaluated arguments for diadic functions! Ash

Can You please specify your question correctly?
I could not able to understand what is your need?

Hi, how is the sensor suppose to detect that there's no movement coming from the phone? Because the phone is still, the numbers keep running. Thanks for the help in advance.
package com.example.testsensors;
import java.util.List;
import android.app.Activity;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.widget.TextView;
import android.widget.Toast;
public class TestSensors extends Activity implements SensorEventListener {
private boolean theRegisteredSensor;
private SensorManager theSensorManager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
theRegisteredSensor = false;
theSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
}
protected void onStart() {
super.onResume();
List<Sensor> sensors = theSensorManager
.getSensorList(Sensor.TYPE_ACCELEROMETER);
if (sensors.size() > 0) {
Sensor sensor = sensors.get(0);
theRegisteredSensor = theSensorManager.registerListener(this, sensor, SensorManager.SENSOR_DELAY_FASTEST);
}
}
@Override
protected void onPause() {
if (theRegisteredSensor) {
theSensorManager.unregisterListener(this);
theRegisteredSensor = false;
}
super.onPause();
}
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}
@Override
public void onSensorChanged(SensorEvent event) {
StringBuffer StringBuff = new StringBuffer();
if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER){
StringBuff.append("Accelerometer\n");
StringBuff.append("X-axis:").append(event.values[0]).append("\n");
StringBuff.append("Y-axis:").append(event.values[1]).append("\n");
TextView tv = (TextView) findViewById(R.id.accero_counters);
tv.setText(StringBuff.toString());
Toast.makeText(getBaseContext()
, "Movement is detected.",Toast.LENGTH_SHORT).show();
}
}
}

I don't know a huge amount about the android SDK, but you need to keep in mind that you're dealing with real data which includes things like quantisation errors and jitter. It may be more appropriate to consider movement below a threshold still, as you probably won't get a value that never changes or stays on zero.
Also, the accelerometer will be detecting gravity, so in one direction you will always get a constant-ish value, the direction depending on which way up the phone is.

Hello All,
I am new to the Android technology, i need some help in implementing google maps. My problem is:
I want to use google map search in android.
For example if i type restaurants in the below url in the ie eplorer, the map will open with markers.
http://maps.google.com/maps?hl=en&q=restaurants&um=1&ie=UTF-8&sa=N&tab=wl
How can i do this in android using google api's.
Thanks in advance,
Poornima

By the looks of it you have to sign up:
http://code.google.com/android/maps-api-signup.html[^]
OR:
You could have a look at this: http://code.google.com/apis/maps/documentation/staticmaps/[^]
And you could easily use this code once you look at the examples (you could simply download the map image, and then diplay the image). I've done a bit of work with this for desktop machines, it's fairly straight forward to do. (And at least this way you won't have to sign up to anything).
See if you can crack this: fb29a481781fe9b3fb8de57cda45fbef

Hi
I have a general type of question. I have an IP camera which supports 3GP container(3GPP file format) video streaming. I need to show the feed from that camera in a windows mobile app(using .NET CF). Does anybody have any experiencies with this type of programming? Any help (links, documents, sample code, advices ...) will be appreciated.

Hi All,
I am new to Andriod Development, and i am using Eclipse java IDE.
i am having troubles when i edit any files. The application is working fine unless each time if you need to change in any of the layout files or manifiest. (baiscally the XML files) it always troubling me 
just generating a empty of the file name with an "out" extention. example main.out.xml.
then i have do delete the file and uload/load project manytimes and then it will come back to normal. this problem making me nurvois to change any files.
can anybody tell me what is exactly the cause of this problem?
thanks
