Android BroadCastReciever Example

When an event happens if users need intimation we can use Broadcast Receiver.Event like incoming/outgoing calls.

You can download source code here.

Following steps:-

Add Receiver and Permission from android manifest.

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.etr.broadcastreceiverexample"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk

        android:minSdkVersion="8"

        android:targetSdkVersion="18" />

    <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />

  <application

            android:allowBackup="true"

            android:icon="@drawable/ic_launcher"

            android:label="@string/app_name"

            android:theme="@style/AppTheme" >

            <activity

                android:name="com.etr.broadcastreceiverexample.BroadCastActivity"

                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=".ReceiverHandler" >

                <intent-filter>

                    <action android:name="android.intent.action.NEW_OUTGOING_CALL" />

                </intent-filter>

            </receiver>

  </application>

</manifest>

Create another class to extend BroadcastReciever.

package com.etr.broadcastreceiverexample;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;

public class ReceiverHandler extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
try {
Toast.makeText(context, "OutGoing call is progress",
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Log.e("ReceiverHandler Exception", Log.getStackTraceString(e));
}
}

}
