Epson printer connect fails status ERR_CONN

I have an Epson printer and I used epos2_printer (sample project) code given with SDK to integrate with my app. I have copied the same code but it never seems to work!
However, the same works when I connect the sample project to my printer.

}
return true;
}
It always gives me exception ERR_CONNECT on printer.connect inside connectprinter function.
What am I doing wrong?
This code works fine with the sample app.
P.S: I have tried to connect this app before connecting the sample app to check if the sample app holds the connection and does not allow other apps to connect but that is not the case. Epson help is unable to provide any further help.

Looks like you don't have the proper permissions in your manifest. Try putting these in your project under the manifest tag:
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
They also have the
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
permission but I'm not sure you need it. I think the essentials are Bluetooth and Internet permissions.

As I suspect there seems to be an error in connect printer method. I have used this SDK once so better follow the documentation properly (means don't skip steps). Make sure you have defined permission as mentioned in the SDK.
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<activity android:name=".MainActivity" android:label="#string/app_title" android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"/>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<meta-data android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" android:resource="#xml/device_filter"/>
As I see you haven't mentioned what type of connection you are making thus, in that case, there must be problem in selecting target
Check out the function from SDK:
Public void connect(String target, int timeout) throws Epos2Exception;
You might be using wrong target parameter.
Note: if you are using USB or any other mode make sure run discoverability service as per the docs.
Discovery.start(this, mFilterOption, mDiscoveryListener);
It will return you the required target name. And I am sure no connection failure will occur. Good Luck \o

Status ERR_CONN is basically shows if device cannot be reached or connection failing with device. It can be USB, LAN/NETWORK, Bluetooth Connection failure status.
If you are trying to connect printer with Bluetooth then you must write below permissions:
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
If you are using LAN for network printers then
<uses-permission android:name="android.permission.INTERNET"/>
For USB Printer Connection Use:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
As you are using EPOS2 Sample Project, remember to import Jar file "EPOS2.jar". Click here to download the file.

onReceive does not called after download completed

I'm trying to use android downloadManager via this tutorial . I move broadCastReciever block in a single function, and below is my code:
public void downloadManager(){
boolean is_downloaded = false;
Log.e("error ", "1");
receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Log.e("error ", "2");
String action = intent.getAction();
if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
Log.e("error ", "3");
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterById(enqueue);
Cursor c = dm.query(query);
Log.e("error ", "4");
if (c.moveToFirst()) {
Log.e("error ", "5");
int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL == c.getInt(columnIndex)) {
// download finished successfully
is_downloaded = true;
Log.e("error ", "6");
}
}
}
}
};
getActivity().registerReceiver(receiver, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
}
when I run the project, is_downloaded will remains false. and in logcat I can see just this line:
error: 1
means that the application control will never reach other Logs so
#Override
public void onReceive(Context context, Intent intent)
will never call. but the image downloads successfully. every thing seems OK, where is the problem?

Try to use
<uses-permission android:name="android.permission.SEND_DOWNLOAD_COMPLETED_INTENTS" />
of course, do not forget this:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
if doesn't help try to use BroadcastListener
public class DownloadListenerService extends BroadcastReceiver {
#Override
public void onReceive(final Context context, Intent intent) {
System.out.println("got here");
///// your code here
}
}
}
`
<receiver
android:name="com.example.DownloadListenerService"
android:exported="true" >
<intent-filter>
<action android:name="android.intent.action.DOWNLOAD_COMPLETE" />
</intent-filter>
</receiver>
<uses-permission android:name="android.permission.INTERNET" />
`
Part of code is from here:
https://stackoverflow.com/a/18789470/1979882

try it through AsyncTask, keep isDownloaded false in onPreExecute() then download the content in doInBackground() and then assign true to isDownloaded in onPostExecute().

Repeat Alarm manager in Sending SMS not Sending

I created application that if the button is click it will send SMS to the number that came from webservice. Then I use Alarm Manager to send SMS repeatedly in the number that i get from the web service. It is working fine but when I change the number that I want to send an SMS it will not work. I don't know what is wrong with my code. Here is my code.
This is my code that send an SMS.

I try this code in other real device. In one device works great but in my device the same code doesn't work. Anyone can help me to understand why?

It looks like twitter is null here
AccessToken at = twitter.getOAuthAccessToken(
requestToken,verifier);
because this method is called before you run your AsyncTask which initializes your twitter variable.
Try calling this method in onPostExecute() of your AsyncTask since this method will be called when doInBackground() is finished.

Why onPushMessageReceived() is not called in Geoloqi API in Android?

In my android app i am using Latest Geoloqi API to implement Geofence concept.when user entered into some region he has notify, for that purpose i am using Push Notifications.in GeoReceiver class three callback methods are calling but not onPushMessageReceived().please help me how to do it?
I am creating trigger with current location is it required to enter into region manually or since i am already in the location its not calling?
Note:I ve given required credentials in assets/geoloqi.properties file.when app is launched in logcat "Successfully registered for the C2DM service" msg also displayed.my code:
GeoloqiExampleActivity.java

There was a bug in earlier versions of the Geoloqi Android SDK. If you update to the latest version this problem should be resolved.
