Why I am not receiving the installed apps broadcast?

I am trying to get all installed applications using intents and broadcast receiver, but the problem is I never directs to my onReceive method and so not getting any package name. I am using the following code:

KillAppBCR.java

public class KillAppBCR extends Activity {
private static final String TAG = "BroadcastReceiver";

BroadcastReceiver receiver;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_ADDED);

    receiver = new TestBroadcastReceiver();

    registerReceiver(receiver, filter);

    Log.e(TAG, "onCreate");
    Toast.makeText(KillAppBCR.this,"onCreate",Toast.LENGTH_SHORT).show();

}

TestBroadcastReceiver.java

public class TestBroadcastReceiver extends BroadcastReceiver
 {
 private static final String TAG = "TestBroadcastReceiver";

@Override
public void onReceive(Context context, Intent intent)
{
    String actionStr = intent.getAction();

    Log.e(TAG, "onReceive");
     Toast.makeText(context,"onReceive",Toast.LENGTH_SHORT).show();


    if (Intent.ACTION_PACKAGE_ADDED.equals(actionStr)) {

        Uri data = intent.getData();

    }
}
}

AndroidManifest.xml

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.KillAppBCR"
  android:versionCode="1"
  android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".KillAppBCR"
              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=".TestBroadcastReceiver">
  <intent-filter>
    <action android:name="com.KillAppBCR" />
  </intent-filter>
</receiver>
</application>
</manifest>

I think you have to make sure that your application runs beyond just a gui, i.e. perhaps it should have a service component as well which could note all installations being made. IMHO you are trying to read only new installations, right? Because that is what the code should do, however as TomTasche pointed out, clearly your application will get killed if you navigate away from it. And once your application is dead, nothing, nada. No intents, no notifications, simple.

Why your Activity code most probably doesn't work: You're registering the receiver only temporarily with registerReceiver. So Android will kill your receiver again after you closed your Activity.

What you have to do is replace com.KillAppBCR with android.intent.action.PACKAGE_ADDED in your AndroidManifest.xml. This tells Android to register your receiver permanently.
