AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.enabledisablebroadcastreceiver"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk
        android:minSdkVersion="15"
        android:targetSdkVersion="15" />
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.code4reference.enabledisablebroadcastreceiver.EnableDisableBroadcastReceiver"
            android:label="@string/title_activity_enable_disable_boradcast_receiver" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <!-- Broadcast receiver -->
        <receiver android:name="com.code4reference.enabledisablebroadcastreceiver.AlarmManagerBroadcastReceiver" >
            <intent-filter>
               <action android:name="android.intent.action.TIME_TICK" >
               </action>

               PackageManager.DONT_KILL_APP);
       Toast.makeText(this, "Enabled broadcast receiver", Toast.LENGTH_SHORT).show();
   }

         //You can do the processing here update the widget/remote views.
         StringBuilder msgStr = new StringBuilder();

         Format formatter = new SimpleDateFormat("hh:mm:ss a");
         msgStr.append(formatter.format(new Date()));

You must call sendBroadcast from your activity : 

Intent broadcast = new Intent();
broadcast.setAction("android.intent.action.TIME_TICK");
sendBroadcast(broadcast);

You can put params to your intent.
