Can't display list of wifi connected devices in Android

I have issue with this code.I am trying to display all devices that are connected on the same WIFI in the list.
I did debugging and it shows that connection with WIFI was made but it does not detect any devices, even though there are some connected devices for sure. I did pinging with both sides with computer and android and connection was made.
If you guys have any ideas where could be a problem, please let me know, cause I am out of ideas.

Splash screen activity not working

Hi have created splash screen as a separate project by using this link : http://www.androidhive.info/2013/07/how-to-implement-android-splash-screen-2/ . And it did worked on my emulator . However, when I implemented this in my app. It did not worked . I don' know whats wrong with my code. My main.java, splash screen.java and splash.xml are the following. Please note that I did define my activity in manifest file. Any help will be greatly appreciated...
MainActivity.Java

setVolumeControlStream(AudioManager.STREAM_MUSIC);
findViewById(R.id.button_1).setOnClickListener(this);
findViewById(R.id.button_2).setOnClickListener(this);
findViewById(R.id.button_3).setOnClickListener(this);
}
public void onClick(View v) {
int resId=1;
// Release any resources from previous MediaPlayer
if (mp != null) {
mp.release();
}
switch (v.getId()) {
case R.id.button_1: resId = R.raw.button_1; break;
case R.id.button_2: resId = R.raw.button_2; break;
case R.id.button_3:
startActivity(new Intent(MainActivity.this,SecondActivity.class));
return;
}
// Create a new MediaPlayer to play this sound
mp = MediaPlayer.create(this, resId);
mp.start();
}
}

#Override
public void run() {
// This method will be executed once the timer is over
// Start your app main activity

startActivity(i);

finish();

</application>
</manifest>

It's not clear which package your SplashScreen.java lives in, but
android:name="info.androidhive.androidsplashscreentimer.SplashScreen"
might need to be changed to
android:name=".SplashScreen"
You may have just pasted in the manifest definition from the sample project without adjusting the activity name to match your own project.

This is in response to Aniruddha who requested this code to help me with question asked HERE If anyone else could tell me why my button 2 doesnt work that would be lovely thanks.

What you have
<activity android:name=".ScanResults" />
And when using intent
Intent intent = new Intent(MainActivity.this, ScanResult.class);
ScanResults and ScanResult are not the same.
If Activity is not found you should get ActivityNotFoundException.
This exception is thrown when a call to startActivity(Intent) or one
of its variants fails because an Activity can not be found to execute
the given Intent.

Android GoogleMaps API v2 auth error, i do not get the error when running on an AVD but on my nexus 7 i get an auth error

I am developing an Android application which uses Google maps for android v2. The problem i having is that when i run it using the AVD in Eclipse i recieve no authentication error in the log cat output.
I am now testing my application on an Android tablet (nexus 7 2013) and i recieve this error when executing the application:
12-12 01:09:13.968: E/Google Maps Android API(14759): Authorization failure. Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map.
12-12 01:09:13.968: E/Google Maps Android API(14759): Ensure that the following correspond to what is in the API Console: Package Name: dcs.aber.ac.uk.cs211.group02, API Key: AIzaSyDcnzt6cdjEbCXSCRSTezmUHbaPW679if8, Certificate Fingerprint: 52FDB9ABBBAA062226834E35BF6A39FA2A3E27A7
I have tried to regen the API key, the one in the logcat matches the one provided in the google API console.
I have tried a clean project/clean install on the device several times, still no luck. The reast of the application works fine, only the map does not.
Here is my manifest.xml al the permissions seem ok.
