Application class recreated each time the screen goes on

The steps that explains the problem I faced are below;
1. I start the android application.
2. I put it on backgorund by pressing home button.
3. I turn the screen off.
4. I turn the screen on after some seconds.
5. My application suddenly becomes foreground. I realised that the application is forced to start again and the application class that I used is created again and then the start page of my application (this is login page) is shown although what page is opened before the step 2.
What I have tried so far is below;
I put configChanges and screenOrientation in all the activiy tags in my Androidmanifest.xml (I tried to put them one by one and both together also.)
<activity android:configChanges="orientation|keyboardHidden|screenSize"
android:name="com.myproject.Activity"
android:screenOrientation="nosensor"/>
I also tried to use screenOrientation="portrait" but didn't work.
My problem is related with the How do I disable orientation change on Android?, Prevent Android activity from being recreated on turning screen off and like others, but I could not find the solution of my problem yet.
Can you please help?

Edit 3:****************
I use fragments, maybe this will be the reason, but I am not sure.

The problem is due to a library I used. It works in background and makes the application restarts.
I suspend it when the application goes to background and resume it when it comes foregorund. That is it, the problem is solved.
Thanks you anyway.

You do not have subscription set. If you haven't seen it already please follow the link. Parse Android Push Tutorial
In your Application onCreate:
ParsePush.subscribeInBackground("", new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
Log.d("com.parse.push", "successfully subscribed to the broadcast channel.");
} else {
Log.e("com.parse.push", "failed to subscribe for push", e);
}
}
});
As you may be creating your own sample app, pay close attention to the Manifest configuration, ensure you have right package names.
As noted in the Parse docs, they use GCM when Play-Services is available, which actual Android device will have. Where as they use persistent connection on devices without play-service ie. your emulator. Hope this helps.

Codes for call recording in android

I am making and application that records calls. Here is my code to record a call and save the file in the SD card under songs folder. But the problem is that this code was working fine but later it is not working. I cannot find what is the problem. Can you please help me out?
My Broad cast receiver:
public class BrCallReceive extends BroadcastReceiver {
#Override

Bundle extras = i.getExtras();
Intent x = new Intent (c, EavesDropperActivity.class);
x.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
if (extras != null) {
String state = extras.getString(TelephonyManager.EXTRA_STATE);
Log.w("DEBUG", state);
if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
Log.w("DEBUG", "MATCHES");
Toast.makeText(c, "Launching record APP !", Toast.LENGTH_LONG).show();
c.startActivity(x);

}
}
};
t_manager.listen(p_listener, PhoneStateListener.LISTEN_CALL_STATE);
return;
}

I think the broadcast receiver is not getting activated wile i am calling my phone.
How do you know your broadcast receiver is not working? Place a Log message inside onReceive() right at the beginning. It might be that your extras == null
But how to make my receiver functional now?
Check out example #5 and just follow the same steps.
Bro i dont think activity will get launched.
Well, it does: You are starting it in your onReceive():
Intent x = new Intent (c, EavesDropperActivity.class);
c.startActivity(x);
However, you are not setting any content in your Activity i.e no UI screen is presented because you have this line commented in onCreate() of EavesDropperActivity Activity:
//setContentView(R.layout.main);
So, you need to think hard on what you are trying to achieve in EavesDropperActivity
HTH.

Put this
<android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
in mainfest file for broadcast receiver.

Add your package name to your receiver class as,
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.testapp"
android:versionCode="1"
android:versionName="1.0" >

as far as I know you cant use the backbutton onreceive event that u are using to decline call, but the back button press function i ok and it should work if you use it other than in the broadcast receive onReceive

Thanks in advance.

I haven't gone through whole of your code but i saw manifest file
Like activities (and other components), you must declare all services in your application's manifest file.
Please do change and try.
