The Microsoft Translator API for android samples has already been deprecated since march 2017 (just this yr). So I'm having a hard time translating text on android. Can anyone help me make this work on android?. It's just that I already have this working in java but I can't make it work on Android. I already tried using asynctask , but to no avail, no translation is being outputed. Or prolly I just did a wrong asyc task?.
The Interface of the application is like this:
It just have a simple textfield with translation that should be outputed on the other textfield. The translation is from Korean to English.

I think you did a wrong AsyncTask.
You can do it like this:
private class TransAsynTask extends AsyncTask<String, Void, String>{
#Override
protected String doInBackground(String... strings) {
String output = getTranslation(strings[0]);
return output;
}
#Override
protected void onPostExecute(String s) {
txtTranslatedText.setText("Output: " + s);
super.onPostExecute(s);
}
}
And in the onCreate you call:
String textOrig;
textOrig = txtOriginalText.getText().toString();
new TransAsynTask().execute(textOrig);
/*String output;
output = getTranslation(textOrig);
txtTranslatedText.setText("Translated Text: " + output);*/
Most of the related answers and google contain pretty old contributions referring to this topic. So Im looking for a way to make my Android-Application print receipts (58 mm in width) via a bluetooth thermal receipt printer. Is it necessary to use a printer with a 3rd party API? I thought about to buy a regular bluetooth printer, that can be connected to my device and use the default Android print manager to make a layout for the receipt. Is that possible? Are there any samples, docs or tutorials? Would appreciate it. Thanks in advance
Yes, it's necesary to use a 3rd party SDK. I recommend you Zebra Printers, the have good documentation and code samples, that makes it easy compared to other brands. Download the SDK from here
To make your labels you can use ZebraDesigner that let you visualy create the layout and gives you as output ZPL code that you can send from your app to the Bluetooth printer. Click here to see it.

In the function getListPairedDevices you can get a list of mac addresses to use and then use function print to send your ZLP code.
Here is some ZPL test.

I wrote an applet which takes the MAC address from the local computer.
It works fine on eclipse but at the moment I try to run it via the browser it does not.
after some debugging i've come to realize that this part returns null on browser
InetAddress.getLocalHost();
Can anyone tell me why?
EDIT:
This is code I found somewhere on the web:

private String macAddress;
public void init() {
setMacAddress(getMacAddressFromClient());
}
public void paint(Graphics g)
{
String mac = getMacAddress();
if(mac.isEmpty())
{
mac = "Empty";
}
g.drawString(mac,15,15);
}
public String getMacAddressFromClient() {
String macAddr= "";
InetAddress addr;
try {
addr = InetAddress.getLocalHost();
macAddress += addr.getHostAddress();
NetworkInterface dir = NetworkInterface.getByInetAddress(addr);
byte[] dirMac = dir.getHardwareAddress();
int count=0;
for (int b:dirMac){
if (b<0) b=256+b;

macAddr=macAddr.concat("00");
}

In eclipse: addr has the localhost address
In the browser (IE and chrome) addr is null.

The result that you are seeing (com.demo.model.Administrator#91e143) is the default string representation of the Administrator object, more specifically, it's what is returned by the default toString() method inherited from Object
To print useful information, override public String toString() of Administrator
You need to override Object#toString() in your Administrator class.
This method can return any meaningful representation of the object you want, e.g:
#Override
public String toString() {
return "id = " + id + "email = " + email;
}
You're making a list of Administrators, where you want to make a list of Strings.
Alternatively (and probably better), if you can change the Administrator class, just implement the toString method in it, that will return the string you want to see on the screen.

By putting your XML file into the XML directory of the resources, the Android build system is assuming you want that compiled down into a binary format and it obliges you. Therefore, when you access that input stream and then try to treat it as a textual XML representation it just doesn't work. You have 2 choices.
Move your XML file into the res\raw directory.
Leave it where it is and use the getResources().getXml(R.xml.beacons) API and create a pull parser for your particular XML.
See this link for more details.
