[Q] OnKey error

Check this class below,
______ My Code _______
public class Main extends Activity implements OnKeyListener {
DisplayWord currentWord;
TextView wordStatus;
EditText inputWord;
Button okBtn;
int pos = 1;
char currentChar;
char inputChar;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
currentWord = (DisplayWord) this.findViewById(R.id.trueWord);
currentWord.setText("Bonjure"); // word from database
wordStatus = (TextView) this.findViewById(R.id.wordStatus);
inputWord = (EditText) this.findViewById(R.id.wordInput);
inputWord.setOnKeyListener(this);
}
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (inputWord.getText().toString().length() <= currentWord.getText().toString().length()) {
pos = inputWord.getText().toString().length();
currentChar = currentWord.getText().toString().charAt(pos);
inputChar = inputWord.getText().toString().charAt(pos);
} return false;
}
}
_____ END _____
When running this code, upon entering data into the input box it causes an exception straight away and for the program exit unexpectedley.
I am trying to extract the input word from EditText field and the word stored in a TextView and to compare them char by char as those chars are entered into the input box, sort of a word game, where the character will be highlighted green if it is correct and red if it is not.
I have no idea why this behaviour happens, I can see in debugger an StringIndexOutOfBounds exception, and a ResourceNotFound when I have been tampering with different ways of attempting this, access position or the char array, it always seems to throw an exception.
Any advice or links appreciated,
AnthonyI am trying to post a copy and paste of just text, no links but validation error on starting a new thread is telling me that I cannot submit a message with a link in it? I want to show everyone a simple class because of some problem's i'm having.. any ideas?

[Q] Light Sensor P990 Development

Hi Community,
I am trying to Develop a Light Sensor App for my "Laser Quest Game" on my LG P990. But when i am trying to "connect" to the Sensor it doesn't allow to.
Here is my Code:
I am not able to post teh packages. Sorry for that!
Code:
public class LightSensorActivity extends Activity {
SensorManager mySensorManager;
Sensor myLightSensor;
TextView textLightSensorData;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView textLightSensor = (TextView)findViewById(R.id.tvLight);
textLightSensorData = (TextView)findViewById(R.id.tvAcc);
mySensorManager = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
myLightSensor = mySensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);
if (myLightSensor == null){
textLightSensor.setText("No Light Sensor!"); //THIS IS WHAT I GET!
}else{
textLightSensor.setText(myLightSensor.getName() + "\n " + myLightSensor.getResolution() );
mySensorManager.registerListener(lightSensorEventListener,
myLightSensor,
SensorManager.SENSOR_DELAY_NORMAL);
}
}
SensorEventListener lightSensorEventListener
= new SensorEventListener(){
@Override
public void onAccuracyChanged(Sensor arg0, int arg1) {
// TODO Auto-generated method stub
}
@Override
public void onSensorChanged(SensorEvent arg0) {
// TODO Auto-generated method stub
if(arg0.sensor.getType()==Sensor.TYPE_LIGHT){
textLightSensorData.setText("Light Sensor Date:"
+ String.valueOf(arg0.values[0]));
}else if(arg0.sensor.getType()==Sensor.TYPE_PROXIMITY){
textLightSensorData.setText("Test "
+ String.valueOf(arg0.values[0]) +" " + String.valueOf(arg0.values[1]));
}
}};
}
I only get the "No Light Sensor" Feedback. But there is one on my LG P990. In the "Hidden Menu" of my Cell the ALC Test runs fine!
Do you have any Suggestions how i can read some Values of the Light Sensnor.
Btw the proximity Sensor runs well with this type of code by Changing TYPE_LIGHT to TYPE_PROXIMITY.
Thanks for your help.

[Q][DEV]Android Development Maps Question

I'm trying to develop (for the liveview) using an SDK and need to get a bitmap of Google Maps.
Code:
//Map Section
public class myMap extends MapActivity {
MapView mapView;
Bitmap bitmap;
boolean created = false;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
createMap();
}
public void createMap()
{
// build map and mark point
mapView = new MapView(this, "keykeykeykeykeykey");
mapView.setBuiltInZoomControls(false);
GeoPoint point = new GeoPoint(52242730,-884211);
mapView.getController().animateTo(point);
mapView.preLoad();
// copy MapView to canvas
bitmap = Bitmap.createBitmap(400, 800, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
mapView.draw(canvas);
PluginUtils.sendTextBitmap(mLiveViewAdapter, mPluginId, "Loading Map...", 128, 12);
created = true;
}
public void displayMap()
{
if (created == false)
{
createMap();
}
//Display map on device
Bitmap mybit = Bitmap.createBitmap(128, 128, Bitmap.Config.ARGB_8888);
for(int i = 0; i < 128; i++)
{
for(int j = 0; j < 128; j++)
{
mybit.setPixel(i, j, bitmap.getPixel(i, j));
}
}
//white pixel for debugging
mybit.setPixel(64, 64, Color.WHITE);
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
Is what I've got so far, the code in createMap() was in onCreate() but It didn't seem to be called.
Now it just force closes.
Anyone know how to help? Is there a better place to ask development questions?
Thanks.
-=Edit=-
Oh, and here's the routine calling the map thing, every couple of seconds.
Code:
private class Timer implements Runnable {
@Override
public void run() {
// TODO Auto-generated method stub
myMap theMap = new myMap();
theMap.displayMap();
}
}

Okay, looks like you cant use google street map like this.
Anyone looking for similar solution, I used open street map and downloaded 'slipery tiles' png's. They provide java routines for finding the tile url from lat/lon.

Long Press on Home

Hello, I have never done this for Android, though I do develop web apps. I'd like to give it a shot with the Android OS and my first project would be to modify behavior of long pressing a Home Button on our Note II's. I found some information on the web by using a function to hook into the KeyLongPress and Key ID.
What I would like to know, if where do I begin to start adding my custom functions? Do I create a separate file or put the function in an existing file?
How do I make this apply only during the lockscreen or home screen?
Using the example below, I imagine I need to create a folder called com.example.demo, but not sure where and what else would be needed.
Code:
package com.example.demo;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.KeyEvent;
import android.view.Menu;
public class TestVolumeActivity extends Activity {
boolean flag = false;
boolean flag2 = false;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_splash_screen, menu);
return true;
}
@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {
Log.d("Test", "Long press!");
flag = false;
flag2 = true;
return true;
}
return super.onKeyLongPress(keyCode, event);
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {
event.startTracking();
if (flag2 == true) {
flag = false;
} else {
flag = true;
flag2 = false;
}
return true;
}
return super.onKeyDown(keyCode, event);
}
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {
event.startTracking();
if (flag) {
Log.d("Test", "Short");
}
flag = true;
flag2 = false;
return true;
}
return super.onKeyUp(keyCode, event);
}
}
Any help is appreciated.

It would be helpful to take a look at CM code and how the long press hardware key actions, as well as lock screen button actions are implemented.

Not sure if I understood you correctly, but you can't just put the code in a text file like a PHP script and expect it to work You need to compile it first using the Android SDK.
In any case, you can't hook keys globally the way you are suggesting. You'd need to modify the system's framework files (inside android.policy.jar) for it to work, which frankly sounds to be beyond your capabilities at the moment.

Are you talking about in your own app or for your ROM?

setContentView(R.layout.calc);
initializevars();
add.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
firstno = Integer.parseInt(etfirstno.getText().toString());
result.setText("The number is " + firstno);
}
});
