Android BroadcastReceiver not stopping Camera Intent action

I am trying to 'block' the Camera action while my application is active. The onReceive method is being executed on the BroadcastReceiver, but by the LogCat it seems to be doing so after the Intent has already been executed.

manifest.xml

    package="com" android:versionCode="1" android:versionName="1.0">

            </intent-filter>
        </receiver>

        <activity android:name=".Main" android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

            </intent-filter>
            <intent-filter>
                <action android:name="android.media.action.IMAGE_CAPTURE" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

    </application>


</manifest>

com.receiver.CameraReceiver

package com.receiver;

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

public class CameraReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i(this.toString(), "Suck It Android!");
        abortBroadcast();
    }

    @Override
    public String toString() {
        return "com.receiver.CameraReceiver";
    }
}

Actually I was able to do it by adding

<category android:name="android.intent.category.DEFAULT" />

to my intent fiter, so it looks like:

<receiver android:name="com.receiver.CameraReceiver">
    <intent-filter>
        <action android:name="android.intent.action.CAMERA_BUTTON" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

and this seems to be working, can anybody comment to if this or the android:priority is the proper way.

Also, if I can stop the 'Vibrate' that happens on button press that would be helpful.

Thanks!

I don't know exactly whether i'm completely wrong about this, but it's my understanding, that a BroadcastReceiver won't stop another activity but is being executed parallely.

Edit: I found a thread in the google android dev group that might help you: click

The essence: Set high priority of your Receiver to a high value, so Android chooses your app to start first when the camera button is pressed.

<intent-filter android:priority=*"10000"*>

And first line of your onReceive(): abortBroadcast();
