PhoneStateListener returns null as incoming number

I am developing calls and sms blocking app, I have encountered the problem where I can't get incoming number from phonestatelistener. My code looks like this:
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
case TelephonyManager.CALL_STATE_RINGING:
System.out.println("incoming number PhoneStateListener:" + incomingNumber);
if (sBlockCall>0){
MuteAudio(getContext());
//reject call if number is matched to our blocking number
boolean callShouldBeBlocked = true;
for(int i = 0; i<sWhiteList.size(); i++){
if(sIncomingNumber.contains(sWhiteList.get(i).mNumber)){
UnMuteAudio(getContext());
System.out.println("CONTACT IS IN WHITE LIST");
callShouldBeBlocked = false;
break;
}
}
if(callShouldBeBlocked){
System.out.println("BLOCK CALL");
disconnectPhoneItelephony();
}
} else {
UnMuteAudio(getContext());
}
//IT WORKS
break;
}
}
So my programm works not as I expect it to work, cause it always returns null as incoming number.
My manifest looks like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="oleksandr.ivanets.dontwakemeapp">

</receiver>
</application>
</manifest>

try adding this permissions, in my case this worked.
<uses-permission android:name="android.permission.READ_CALL_LOG"/>

Intent Filter not working for Android Beam NFC

I am sure this is simple but I cannot figure it out. All I am trying to do is send a message via NFC (android Beam) and open my App on the receiver device. I did test my code on a new Project and it worked perfectly but if I try it on my real Project it just start "New Tag collected" and shows application/eu.freemoser.mydebts2go (see my screenshot). I don't know what's wrong maybe something with the manifest? The Google results doesn't match with my problem (or I am just to stupid) but I believe I found some related answer unfortunately I still was not able to solve my problem

Android's MIME type matching for intent filters is case-sensitive (eventhough the MIME types themselves are not). Therefore, with Android (and also pretty much everywhere you use them) you should stick to the convention to use MIME types with lowercase letters only.
Specifically with MIME type records received over NFC, Android will automatically convert them to all-lowercase letters to overcome the problem of case-sensitivity in intent filters. So in your example, changing the type name in the intent filter to "application/eu.freemoser.mydebts2go" should work:
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="application/eu.freemoser.mydebts2go"/>
</intent-filter>
In addition, you should also make sure you send the MIME type in lowercase letters only:
NdefMessage msg = new NdefMessage(
new NdefRecord[]{createMimeRecord(
"application/eu.freemoser.mydebts2go", text.getBytes())});

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
public void onReceive(Context c, Intent i) {

c.startActivity(x);
}

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"

by pressing back button i want to reject android call

I have a BroadcastReceiver and I know how to reject calls. But I need help rejecting a call when I press the back button, because I have some sort of error in my code...

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
