Incoming call receiver not working (Android 4.1)

Question

I am trying to catch the broadcast of an incoming call, but it does not work.

This is my manifest:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.test.bgPicture" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="9" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" /> <uses-feature android:name="android.hardware.camera" android:required="false" /> <uses-feature android:name="android.hardware.camera.front" android:required="false" /> <application android:icon="@drawable/icon" android:label="@string/app_name" > <receiver android:name=".PhoneStateBroadcastReceiver" > <intent-filter> <action android:name="android.intent.action.PHONE_STATE" /> </intent-filter> </receiver> </application> 

This is my broadcast receiver

 package com.test.bgPicture; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager; public class PhoneStateBroadcastReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); telephonyManager.listen(new CustomPhoneStateListener(context), PhoneStateListener.LISTEN_CALL_STATE); } } 

And the listener ..

 package com.test.bgPicture; import android.content.Context; import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager; import android.widget.Toast; public class CustomPhoneStateListener extends PhoneStateListener { //private static final String TAG = "PhoneStateChanged"; Context context; //Context to make Toast if required public CustomPhoneStateListener(Context context) { super(); this.context = context; } @Override public void onCallStateChanged(int state, String incomingNumber) { super.onCallStateChanged(state, incomingNumber); switch (state) { case TelephonyManager.CALL_STATE_IDLE: //when Idle ie no call Toast.makeText(context, "Phone state Idle", Toast.LENGTH_LONG).show(); break; case TelephonyManager.CALL_STATE_OFFHOOK: //when Off hook ie in call //Make intent and start your service here Toast.makeText(context, "Phone state Off hook", Toast.LENGTH_LONG).show(); break; case TelephonyManager.CALL_STATE_RINGING: //when Ringing Toast.makeText(context, "Phone state Ringing", Toast.LENGTH_LONG).show(); break; default: break; } } } 

But toasts do not appear, any ideas?

EDIT: I just tried it with another Android 2.3.6 phone, and it worked there, but it didn’t work on the first device (Android 4.1). Why could this be?

Answer 1

I found the problem, you have to manually start the activity from your application before the broadcast receivers start working with Android 3.0.

Answer 2

Have you tried to add a broadcast receiver inside the service? The service should remain active even when the application is closed / minimized. Check this link
