So in my Android app, I've been testing how to detect an incoming and outgoing call. I got it to work by building a class that extends a BroadcastReceiver, but in that class if I call another class it crashes. For example MyClass mc = new MyClass(); mc.functionname();
My actual app is running a looping sound clip. I want to pause that sound clip when an incoming or outgoing call is made. The soundclip is played in a class that extends Activity. How do I do this?
This is what I have for the BroadcastReceiver class and my manifest.
package com.anthony.phone;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.widget.Toast;
public class inComingReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Bundle bundle = intent.getExtras();
if(null == bundle)
return;
Log.i("MYTAG",bundle.toString());
String state = bundle.getString(TelephonyManager.EXTRA_STATE);
Log.i("MYTAG","State: "+ state);
if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))
{
String phonenumber = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.i("MYTAG",":) Incomng Number: " + phonenumber);
String info = "Detect Calls sample application\nIncoming number: " + phonenumber;
Toast.makeText(context, info, Toast.LENGTH_LONG).show();
}
}
}
and my manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.anthony.phone"
android:versionCode="1"
android:versionName="1.0" xmlns:android="http://schemas.android.com/apk/res/android">
<uses-sdk android:minSdkVersion="10" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity

android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

</activity>
<receiver android:name="com.anthony.phone.inComingReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE"/>
</intent-filter>
</receiver>
</application>
</manifest>
i had also this kind of problem. i solved by calling activity from broadcast receiver And writing my class code in particular Activity. As mentioned below
Intent i = new Intent(context,newActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
i hope it will help you to solve your query.
ask me if you further have any doubt.

I am trying to display toast on incoming call received. but i am not getting any display. I have mention the receiver inside the manifest file which also contains permission required for phone calls.
the following is code that i have used.
// inside IncomingCall broadcastreceiver
package com.example.shailesh.callbroadcastreceiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.widget.Toast;
public class IncomingCall extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_RINGING)) {
// This code will execute when the phone has an incoming call
// get the phone number
String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
Toast.makeText(context, "Call from:" +incomingNumber, Toast.LENGTH_LONG).show();
} else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
TelephonyManager.EXTRA_STATE_IDLE)
|| intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
TelephonyManager.EXTRA_STATE_OFFHOOK)) {
// This code will execute when the call is disconnected
Toast.makeText(context, "Detected call hangup event", Toast.LENGTH_LONG).show();
}
}
}
And i have specify in menifest file as follows :
<?xml version="1.0" encoding="utf-8"?>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".IncomingCall" android:enabled="true">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
</application>
what else i have to include in order to get toast display on incoming call received.
i Have also included following code in my MainActivity
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent i = new Intent(getApplicationContext(),IncomingCall.class);
startService(i);
}
}
is class IncomingCall a service ? if not then why you are firing an intent to start service.
I am new to android. I am working on broadcastreceiver. I want to create a receiver listening outgoing call. What I expected is when ever out going call is made write logcat " It is Ok" .
But it show message on log as "unexpected value from nativegetenabledtags".
Following is my manifestFile.
<uses-permission android:name="android.permission.READ_PHONE_STATE" >
</uses-permission>
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="de.vogella.android.receiver.phone.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="MyPhoneReceiver" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" >
</action>
</intent-filter>
</receiver>
</application>
Following is receiver Class
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;
public class MyPhoneReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Bundle extras = intent.getExtras();
if (extras != null) {
String state = extras.getString(TelephonyManager.EXTRA_STATE);
Log.w("MY_DEBUG_TAG", state);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
String phoneNumber = extras
.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.w("MY_DEBUG_TAG", phoneNumber);
}
}
}
}
Please give me some solution.
I'm not sure if this is the exact reason but for your class name you need to put a dot (.) in the front. Like below.
<receiver android:name=".MyPhoneReceiver" >
I'm not sure if this is your exact issue but without the . will cause you other issues if this isn't the reason
Check this answer: Unexpected value from nativeGetEnabledTags: 0
Add this filter to the LogCat: ^(?!.(nativeGetEnabledTags)).$
It is a bug introduced in the latest revision of the tools... Google is working on a fix on the next version
I am new to android, i am trying a broadcast demo, I gave my best effort by reading the documentation but its not working. Please have a look at my code:
BroadcastDemoActivity.java
package com.broadcastdemo;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class BroadcastDemoActivity extends Activity {
/** Called when the activity is first created. */
public static final String PUBLIC_HOLIDAYS = "com.paad.action.PUBLIC_HOLIDAYS";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent intent = new Intent(PUBLIC_HOLIDAYS);
intent.putExtra("Holiday", "8th April is a holiday");
sendBroadcast(getIntent());
}
}
Receive.java
package com.broadcastdemo;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class Receive extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String message = intent.getStringExtra("Holiday");
Toast.makeText(context, message, Toast.LENGTH_SHORT).show();
}
}
Manifest.xml
<?xml version="1.0" encoding="utf-8"?>

I know that i am missing something which i am not aware of, please help.
I believe your problem is in the call to sendBroadcast.
Intent intent = new Intent(PUBLIC_HOLIDAYS);
intent.putExtra("Holiday", "8th April is a holiday");
sendBroadcast(getIntent());
You are not sending the intent that you construct, you're sending the intent returned from getIntent(), which will be the intent that the activity was started with.
It should be
Intent intent = new Intent(PUBLIC_HOLIDAYS);
intent.putExtra("Holiday", "8th April is a holiday");
sendBroadcast(intent);
I am trying to test Broadcast receiver for outgoing calls. Please help.
Here is my CallCounter class:
package com.callout;
import android.content.Context;
import android.content.Intent;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
public class CallCounter extends PhoneStateListener {
public void onCallStateChanged(int state, String incomingNumber) {
switch(state) {
case TelephonyManager.CALL_STATE_IDLE:
Log.d("Tony+++++++++++","Outgoing Call finished");
// Call Finished -> stop counter and store it.
// callStop=new Date().getTime();
Context c = getApplicationContext();
c.stopService(new Intent(c,ListenerContainer.class));
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.d("++++++++++++++++Tony","Outgoing Call Starting");
// Call Started -> start counter.
// This is not precise, because it starts when calling,
// we can correct it later reading from call log
// callStart=new Date().getTime();
break;
}
}
private Context getApplicationContext() {
// TODO Auto-generated method stub
return this.getApplicationContext();
}
}
Here is myReceiver
package com.callout;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class myReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
Log.d("T+++++++++++++++++ony","In mYRecieverrr");
context.startService(new Intent(context,ListenerContainer.class));
}
}
}
Here is myService:
package com.callout;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
public class ListenerContainer extends Service {
public class LocalBinder extends Binder {
ListenerContainer getService() {
Log.d("Tony","OKKK HEREEEEEEEEEEEEEeEEEEE");
return ListenerContainer.this;
}
}
#Override
public void onStart(Intent intent, int startId) {
TelephonyManager tManager =(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
CallCounter callCounter=new CallCounter();
tManager.listen(callCounter,PhoneStateListener.LISTEN_CALL_STATE);
Log.d("To++++++++++++++ny","Call COUNTER Registered");
}
#Override
public IBinder onBind(Intent intent) {
return mBinder;
}
private final IBinder mBinder = new LocalBinder();
}
And this is the manifest file if i m missing some permission:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.callout"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".CallCounter"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".myReceiver"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:enabled="true" android:name=".ListenerContainer" />
<receiver android:name=".myReceiver">
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
</application>
</manifest>
Please point out my mistake.
You must add the following permission to your manifest since your are registering a phonestatelistener.
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
It looks like your receiver is missing an attribute in the manifest file :
http://developer.android.com/guide/topics/manifest/receiver-element.html
Look at the exported attribute, it should be set tot true to receive broadcast from other apps.

There's a working solution with full source here that meets your requirements
https://www.codeproject.com/articles/548416/detecting-incoming-and-outgoing-phone-calls-on-and
I am beginner android developer.
I am trying to call BroadcastReceiver from Activity because I need to update entry if somebody call me.
This is the activity where I am calling BroadcastReceiver.
Source code:
public class CalendarCall extends Activity {
private static final String TAG = "CalendarCall";
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent i = new Intent(this, MyBroadcastReceiver.class);
startActivity(i);
}
// ......
}
MyBroadcastReceiver.class:
package org.example.calendarcall;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;
public class MyBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Bundle extras = intent.getExtras();
if (extras != null) {
String state = extras.getString(TelephonyManager.EXTRA_STATE);
Log.w("DEBUG", state);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
String phoneNumber = extras
.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.w("DEBUG", phoneNumber);
}
}
}
}
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.example.calendarcall"
android:versionCode="1"
android:versionName="1.0">

<uses-permission android:name="android.permission.READ_CALENDAR"/>
<uses-permission android:name="android.permission.WRITE_CALENDAR"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
</manifest>
Error:
04-21 12:37:40.821: ERROR/AndroidRuntime(793): java.lang.RuntimeException: Unable to start activity ComponentInfo{org.example.calendarcall/org.example.calendarcall.CalendarCall}: android.content.ActivityNotFoundException: Unable to find explicit activity class {org.example.calendarcall/org.example.calendarcall.MyBroadcastReceiver};
I think the problem is declaraction in Manifest and i also dont know if i can call BroadcastReceiver from Activity using:
Intent i = new Intent(this, MyBroadcastReceiver.class);
startActivity(i);
A BroadCastReceiver receives intents from sender's who's calling the sendBroadcast() method. If you would like your MyBroadcastReceiver to be invoked when someone calls you, you could add the filter android.intent.action.PHONE_STATE like:
<receiver android:name=".MyBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
You don't really need your CalendarCall activity.
If you want to transfer information from your broadcast receiver to your activity, see this stackoverflow question.
you can call a broadcaste reciever from activity.
you need to register and unregister the reciever and you need to call sendbroadcastereciver() also in your code
