How to Print a Image At full Paper size(80MM) in thermal printer(EPSON)

I followed Epson SDK for android to thermal print receipts...
So instead of the text I am given some Image which contains entire image..
at the part of Logoimage(the store).. Which is like below
Here the Store is the Logoimage Insted of that I have given My Recipt(Image) So I am getting like above.. Its not printing full size...
this is my code
public class MainActivity extends Activity implements View.OnClickListener, ReceiveListener {
private Context mContext = null;

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..

Chromecast - SIGN_IN_REQUIRED

Only a small portion of my users are getting this error and I can't for the life of me figure it out. I use GooglePlayServicesUtil.isGooglePlayServicesAvailable(downloadService) to test whether or not Play Services is available, and it always returns SUCCESS. I setup the channel to connect to the Chromecast, and everything works fine up until the point where I try to use RemoteMediaPlayer.load. The result is always SIGN_IN_REQUIRED for some users, with resolution: null. The status.toString() is Failed to load: Status{statusCode=SIGN_IN_REQUIRED, resolution=null}. I'm really not sure what I am supposed to with this or how to get rid of the error for my few users who are getting this.

It is strange that you are getting such status code at that time. What comes to mind is that the user may have not logged into his/her gmail account or something along those lines. Do you have the log file for us to take a look at to see if we can get more from the context? Also, to be sure, such user sees the application launched on the TV and only when it comes to loading a media that error is thrown?

The issue is due to using a Self Signed Certificate. I didn't realize the issue on my old phone because I had changed hosts and bought a normal certificate after switching phones. It would be nice if the SDK would through a useful error though. The one thrown makes you think that it is a problem with connecting to the Play Services SDK, and not a problem with the actual URL being used.

Android synchronizing threads

My code have more than one thread and Runnable. My problem is i change the value of a certain variable in the thread that the Runnable calling .
After the calling i make a check on that variable value but the value was not retrieved yet.
How can i retrieve the value after the processing? Here is the Runnable and the Thread code:
final Runnable r = new Runnable()
{
public void run()
{
if(flag==true)
onSwipe();
if(SwipeAgain==true)
handler.postDelayed(this, 1000);
}
};
private void onSwipe() {
new Thread() {
public void run() {
String data = null;
decryption_data = null;
encryption_data = null;
SwipeAgain=false;
handler.post(clear_encryption);
try {
data = sreader.ReadCard(15000);
} catch (Exception ex) {
if (ex instanceof TimeoutException) {
return;
} else
CloseSinWave();
}
if (data == null) {
SwipeAgain=true;
encryption_data = sreader.GetErrorString();
if (encryption_data.equalsIgnoreCase("cancel all"))
return;
handler.post(display_encryptiondata);
} else {
encryption_data = "\n" + data;
handler.post(display_encryptiondata);
}.start();
}
SwipeAgain is the value i want after processing

You have to use Callable, Runnable interface do not pass values to the parent method.
See this example.
You may require to use Generic Objects

Use a MONITOR final Object to wait and notify it when processing is done.
private final MONITOR Object[] = new Object[0];
private AtomicBoolean ready = new AtomicBoolean(false);
final Runnable r = new Runnable() {
public void run()
{
if(flag==true){
ready.set(false);
onSwipe();
synchronized(MONITOR){
if(!ready.get()){
try{
MONITOR.wait(); //will block until it get notified
}catch(InteruptedException e){}
}
}
}
if(SwipeAgain==true)
handler.postDelayed(this, 1000);
}
};
private void onSwipe() {
new Thread() {
public void run() {
try{
String data = null;
decryption_data = null;
encryption_data = null;
SwipeAgain=false;
handler.post(clear_encryption);
try {
data = sreader.ReadCard(15000);
} catch (Exception ex) {
if (ex instanceof TimeoutException) {
return;
} else
CloseSinWave();
}
if (data == null) {
SwipeAgain=true;
encryption_data = sreader.GetErrorString();
if (encryption_data.equalsIgnoreCase("cancel all"))
return;
handler.post(display_encryptiondata);
} else {
encryption_data = "\n" + data;
handler.post(display_encryptiondata);
}finally{
synchronized(MONITOR){
ready.set(true);
MONITOR.notifyAll(); //notify (and so unblock r.run())
}
}
}.start();
}

android multithreading: thread.join() does not work as expected

I have trouble using thread.join in my code below. It should wait for the thread to finish before executing the codes after it, right? It was behaving differently on different occasions.
I have three cases to check if my code goes well
App is used for the first time - works as expected but the loading page don't appear while downloading
App is used the second time (db is up to date) - works okay
App is used the third time (db is outdated, must update) - won't update, screen blacks out, then crashes
I think I have problems with this code on onCreate method:
dropOldSchedule();
dropThread.join();
triggerDownload();
Based on the logs, the code works until before this part... What can be the problem?

Sorry but I couldn't find mistakes or problems in your code. But I would strongly recommend you to use AsyncTask for doing something in different thread. AsyncTask is very easy to use and I would say that it is one of the biggest advantages of java. I really miss it in obj-c.
http://labs.makemachine.net/2010/05/android-asynctask-example/
http://marakana.com/s/video_tutorial_android_application_development_asynctask_preferences_and_options_menu,257/index.html
check those links hope that will help you.

It was already mentioned that AsyncTask is the better alternative. However, it may be the case, that your call to join will throw InterruptedException. Try to use it like this:
while(getUploadDateThread.isRunning()){
try{
getUploadDateThread.join();
} catch (InterruptedException ie){}
}
// code after join

I think the problem that your facing is that you are blocking the UI thread when you call join in the onCreate() method. You should move this code into another thread which should execute in the background and once its done you can update the UI.
Here is a sample code:
final Thread t1 = new Thread();
final Thread t2 = new Thread();
t1.start();
t2.start();
new Thread(new Runnable() {
#Override
public void run() {
// Perform all your thread joins here.
try {
t1.join();
t2.join();
} catch (Exception e) {
// TODO: handle exception
}
// This thread wont move forward unless all your threads
// mentioned above are executed or timed out.
// ------ Update UI using this method
runOnUiThread(new Runnable() {
#Override
public void run() {
// Update UI code goes here
}
});
}
}).start();
