Save calculator result problem

Here's where the button is pressed:
btnMP.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
memNum = memNum + Double.parseDouble(txtCalc.getText().toString());
operator = 0; }
});
Here's a thingie I hammered together from parts:
// Save MEMORY
public void WriteMemory(OnClickListener onClickListener, double
memNum){
File sdcard = Environment.getExternalStorageDirectory();
File destinationdir = new File(sdcard,"/download/calculator");
destinationdir.mkdir();
File destinationfile = new File(destinationdir,"memory.dat");
FileOutputStream fOut = null;
OutputStreamWriter osw = null;
try{
destinationfile.createNewFile();
fOut = new FileOutputStream(destinationfile);
osw = new OutputStreamWriter(fOut);
osw.write((int) memNum);
osw.flush();
Toast.makeText((Context) onClickListener, "Memory
saved",Toast.LENGTH_SHORT).show();
}
catch (Exception e) {
e.printStackTrace();
// Toast.makeText((Context) onClickListener, "Memory not
saved",Toast.LENGTH_SHORT).show();
}
finally {
try {
osw.close();
fOut.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
This is called by inserting WriteMemory(this,memNum); in the button
routine thusly:
btnMP.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
memNum = memNum + Double.parseDouble(txtCalc.getText().toString());
operator = 0; }
WriteMemory(this,memNum);
});
The file is created but only a 0 is written in it. What's missing?

[Q] Audio Level Meter

Hello
I'm new to programming and I'm trying to make a java application that will "hear" (not record necessarily) the sound and display how loud is.I'm thinking of converting the sound recordings to numbers,so I can see the difference on the sound levels.I got this code and I added the "getLevel()" method,which returns the amplitude of the current recording,but it's returning -1 everytime.I guess I'm not using it properly. Any ideas how I must call this method?I have to deliver my project in a week,so any help will be much appreciated!
Code:
public class Capture extends JFrame {
protected boolean running;
ByteArrayOutputStream out;
public Capture() {
super("Capture Sound Demo");

Ok,I managed to make it capture audio and print on a xls file the timestamp and the value of the current sample,but there is a problem : even I've put some spaces between the time and the value and it seems that they are in different columns,they are actualy on the same column of the xls,it's just expanded and covers the next column (I can put a print screen if you don't understand).How can I make it print the data of time and amplitude in two different columns?Here's my code of the class which creates the file and saves the data on xls :
Code:
package soundRecording;
import java.io.File;
import java.util.Formatter;
public class Save {
static Formatter y;
public static void createFile() {
Date thedate = new Date();
final String folder = thedate.curDate();
final String fileName = thedate.curTime();
try {
String name = "Time_"+fileName+".csv";
y = new Formatter(name);
File nof = new File(name);
nof.createNewFile();
System.out.println("A new file was created.");
}
catch(Exception e) {
System.out.println("There was an error.");
}
}
public void addValues(byte audio) {
Date d = new Date();
y.format("%s " + " %s%n",d.curTime(), audio);
}
public void closeFile() {
y.close();
}
}

How to crop bitmaps according to size of a custom view

Trying to make a motion detection app. The intention is to make the app take pictures when motion is detected by comparing two images. Up to this part, the app is working fine.
Requirement:
To specify area of detection by a custom view. So that, the pictures will be captured only if a motion is detected inside the defined area by calculating the detection area.
What I have tried:
Created a movable custom view, like a crop view of which the dimensions (`Rect`) are saved in the preference each time when the view is moved.
In the detection thread I tried setting the width and height from the preference like
Code:
private int width = Prefe.DetectionArea.width();
private int height = Prefe.DetectionArea.height();
But it didn't work.
What is not working:
The motion detection from inside the custom view is not working. I believe that the bitmaps must be cropped according to the size of the custom view.
Please help me by explaining how this could be achieved so that the motion detection will happen according to the size of the custom view. I'm new to android and trying to self learn, any help is appreciated.
