I have write the following code to write a file-

FileOutputStream fos = context.openFileOutput("MyFile",Context.MODE_PRIVATE);

ObjectOutputStream os = new ObjectOutputStream(fos);

//Saving my list
os.writeObject(EmailStackClass.list);
os.close();

how can i identify if the file is already exist ? Because if the file is created previously, then i have to append my data on the previous file. Please help me...

try below code :-

File f = new File("MyFile"); // PATH OF YOUR FILE
        if(f.exists())
        {
            System.out.println("file exist");
        }
        else
        {
            System.out.println("file not exist");
        }

You can check as follows...

File file = getBaseContext().getFileStreamPath(fileName);
if(file.exists()) {

    //do something with the existed file
}

First Check this.. 

File file = new File("dirPath", "fileName");
if(file.exists()){
        // file exists
}else{
        // file not exists
}

hope this help you..
