Anyone can help please...

I've tried my best to do my coding but i'm really in a desperate bit to get some help from you guys here... Could someone please help me, not that i'm lazy or what to do the coding myself but its just that i'm really bad in programming and new to android but yet force to do this project so decided to ask for help from you guys here...

I found this online but it seems that it answer part of my question isn't it but i don't seem to know how to integrate it into my codes... Can someone help me with this problem?
Code:
private static long dirSize(File dir) {
long result = 0;
Stack<File> dirlist= new Stack<File>();
dirlist.clear();
dirlist.push(dir);
while(!dirlist.isEmpty())
{
File dirCurrent = dirlist.pop();
File[] fileList = dirCurrent.listFiles();
for (int i = 0; i < fileList.length; i++) {
if(fileList[i].isDirectory())
dirlist.push(fileList[i]);
else
result += fileList[i].length();
}
}
return result;
}

Could someone guide me along with the above codes??

[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.

I have fragment(ThreeFragment) with button(InternalBtn) that have a context menu. Context menu registered with registerForContextMenu(IntBtn); Menu item ClearCacheMet not working. I cannot see neither Toast.makeText().show(); nor Log.d(TAG, "ClearCache"); Common and ITEM_CANCEL items working. I cannot understand why? Please help me.
Toast.makeText(getActivity(), "Called !", Toast.LENGTH_SHORT).show(); not called in ClearCache() function. ClearCacheMet and Common were initialized in other fragment.
public class OneFragment extends Fragment {
public View OneFragmentView = null;
public static final int Common = 25;
public static final int ClearCacheMet = 50;
