Finally found a solution, the problem was with the android:launchMode in the manifest.

Try this,
This is useful to check whether a TTS engine is not available
Intent TTSIntent = new Intent();
TTSIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(TTSIntent, 2);
This is the code when onActivityResult, before running tts.speak ()
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == 2) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
try{

I have a failed binder transaction error when the app quits abnormally,but there is nothing in intent.
The images of every xml are lower than 40K,so I think it's not the problem of images.
This is my code.

I am new to android programming,I got a chance to work with (wifi printers).In my application I have a pdf file which needs to be taken a printout by using wifi printer
I didnt have much idea on this,but after doing a research I got that,there are 3 things to be done for doing this
1)getting the list of devices which are connected to wifi network which my mobile is using right now.
2) Then,select a device and make a connection with that device.
3) Transfer data to a printer
I hope these are the steps which I need to use.
I worked on first point,but I am getting the (Wifi networks like Tata communications,vonline etc) but not the devices which are connecting to that networks.
Here is the code I used.........
public class WiFiDemo extends Activity implements OnClickListener
{
WifiManager wifi;
ListView lv;
TextView textStatus;
Button buttonScan;
int size = 0;
List<ScanResult> results;
String ITEM_KEY = "key";
ArrayList<HashMap<String, String>> arraylist = new ArrayList<HashMap<String, String>>();
SimpleAdapter adapter;
/* Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// textStatus = (TextView) findViewById(R.id.textStatus);
buttonScan = (Button) findViewById(R.id.buttonScan);
buttonScan.setOnClickListener(this);
lv = (ListView)findViewById(R.id.list);
wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
if (wifi.isWifiEnabled() == false)
{
Toast.makeText(getApplicationContext(), "wifi is disabled..making it enabled", Toast.LENGTH_LONG).show();
wifi.setWifiEnabled(true);
}
this.adapter = new SimpleAdapter(WiFiDemo.this, arraylist, R.layout.row, new String[] { ITEM_KEY }, new int[] { R.id.list_value });
lv.setAdapter(this.adapter);
registerReceiver(new BroadcastReceiver()
{
#Override
public void onReceive(Context c, Intent intent)
{
results = wifi.getScanResults();
size = results.size();
}
}, new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));
}
public void onClick(View view)
{
arraylist.clear();
wifi.startScan();
checkWifi();
Toast.makeText(this, "Scanning...." + size, Toast.LENGTH_SHORT).show();
try
{
size = size - 1;
while (size >= 0)
{
HashMap<String, String> item = new HashMap<String, String>();
item.put(ITEM_KEY, results.get(size).SSID + " " + results.get(size).capabilities);
arraylist.add(item);
size--;
adapter.notifyDataSetChanged();
}
}
catch (Exception e)
{ }
}
private void checkWifi(){
IntentFilter filter = new IntentFilter();
filter.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
final WifiManager wifiManager =
(WifiManager)this.getSystemService(Context.WIFI_SERVICE);;
registerReceiver(new BroadcastReceiver(){
#Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
Log.d("wifi","Open Wifimanager");
String scanList = wifiManager.getScanResults().toString();
Log.d("wifi","Scan:"+scanList);
}
},filter);
wifiManager.startScan();
}
}
please suggest for the solution
Thanks in advance friends
Refer this Android-wifi-print - Github, Which contains a demo application I created for the same.
Edit :
As #NileshThakkar said. we may lost connection to that link in future so, I am posting code here.. with flow.
checks connectivity.
If connected in WiFi.. am storing that WiFi configuration.
Now checking whether I already have printer's information (WiFi configuration of WiFi printer) is available or not. If available, I'll scan and get list of WiFi ScanResults and connects to that else.. It'll showing list of WiFi and clicking on that, user will connect to printer and stores that WiFi configuration for future printing jobs.
After print job completes, I'm connecting to my previous WiFi or Mobile data connection.
Now going back to 2nd step.
If user connected in Mobile data, I'm just enabling WiFi and following 3rd step.
After Print job completes, I'm just disabling WiFi. so that, We'll be connected back to Mobile data connection. (That is android default).
