can any one suggest me where do I adjust the size of the image so that I should print the page area instead of logo size...
this is Image content data
for Image
String method = "";
Bitmap logoData = BitmapFactory.decodeResource(getResources(), R.drawable.store);
//I have given this Bitmap logoData = BitmapFactory.decodeResource(getResources(), R.drawable.full);
and this is for image content..
method = "addImage";
mPrinter.addImage(logoData,0,0,logoData.getWidth(),logoData.getHeight(),Printer.COLOR_1,Printer.MODE_MONO,Printer.HALFTONE_DITHER,Printer.PARAM_DEFAULT,Printer.COMPRESS_AUTO);
Please suggest how to print the image content at full size...
I am getting a side of page..
It should Print 80 mm of Size but its printing 40 mm can any one suggest me how to make it to full size or how to adjust the size of the Image to stretch it to max paper area...

Your question is a bit unclear.
I think your question is:
You are given the data for the image at some resolution as an Android BitMapFactory.
You want to print on some printer, with another DPI. The Android BitMapFactory for the image is already set.
You need to scale the BitMapFactory for your logo.
First, in your line of getting the logo data, you can try just exploring the option BitmapFactory.Options.inSampleSize to get about that right size. That would get you a better, but not perfect answer.
For perfect, you should scale the logo. You can use code here. See also the related questions here and here.

In the same way I want to print PDF. Is this Possible without any library?
Or else is it possible to print PDF in thermal Printer?
Can anyone suggest me how to print PDF in a thermal printer?
Here I have this to print a Image/bitmap
Bitmap logoData = BitmapFactory.decodeResource(getResources(), R.drawable.store);
StringBuilder textData = new StringBuilder();
final int barcodeWidth = 2;
final int barcodeHeight = 100;
with addimage.. and for text I am giving plain text... with addtext....
Can Any one suggest Me How to add a PDF to this...
I followed May tutorials,... But Nothing Found related to PDF in thermal Printer(EPSON) Printer..

ListView sometimes does not react on tap on an element

I have a ListView in an activity. The list elements are generated from a BaseAdapter. The list is continously growing as the user scrolls down on the screen. Actually an AsyncTask is responsibe to download data from the internet and generate the View elements for the ListView.
Each View element has a set onClickListener. The OnClickListener class starts a new activity...
The problem is that sometimes the GUI does not react on the click action.
e.g.
1. start the app
2. tap on the first element -> nothing happens
3. tap on the 2nd element -> nothing happens
4. scroll down a but -> both corresponding activities appear (on each other)

How to get List of Data in Tabbed Actvity?

I have made a program in which i am fetching list of all my Facebook Friends with their name, dob and profile picture, but i have decided to use tabs in my existing program therefore, i have also written code for that, but whenever i run my app, every time i am getting tabs but not getting list of friends..
In my case i am not getting FriendsList Activity data in TabSample Class, why?

} catch (JSONException e) {
FacebookUtility.displayMessageBox(this, this.getString(R.string.json_failed));
}
and any other code need to move from FriendsList class to TabSample Class
