I eventually solved the problem with help of following dicussion
http://www.anddev.org/viewtopic.php?p=25297#25297
my solution is:-
public void CopyfiletoMemory(String filename){
FileOutputStream fos;
DataOutputStream out;
try{
FileInputStream in = new FileInputStream("/
sdcard/"+filename);
boolean success = new File("/data/data/com.example.test2/
data").mkdir();
if (!success)
System.out.println( "no success");
File file = new File("/data/data/com.example.test2/
data/"+filename);
file.createNewFile();
if(!file.exists()){
file.createNewFile();
System.out.println( "File created...");
}
fos = new FileOutputStream(file);
out=new DataOutputStream(fos);
// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
out.flush();
in.close();
out.close();
listfiles();
System.out.println("File Copied");
}
catch (Exception e){
System.err.println("File input error");
}
}
private void listfiles(){
FilenameFilter fil=null;
String destination = "/data/data/com.example.test2/data/";
File fileCon[] = new File(destination).listFiles(fil);
for (int n=0;n<fileCon.length;n++)
System.out.println("File "+fileCon[n]);
}
public void Openfile(String filename){
try
{
listfiles();
fstream = new RandomAccessFile("/data/data/
com.example.test2/data/"+filename,"rw");
......
Hope this helps other newbies who can't figure out file creation.
