BroadcastReceiver onReceive does not work (custom Unity Android plugin)

Hello friends.
I am working in a plugin to capture the actions of an external input-peripheral and send these to a game in Unity.
I have a class in java that extends UnityPlayerActivity, here, I have override some methods to test if the conexion between this class and Unity is working, for example, the onStart method it is call.
The main point is that I need to create a BroadcastReceiver, and I do it like this:

protected static final int EVENT_BUTTON = 8000;
protected static final int EVENT_BUTTON1 = EVENT_BUTTON + 1;
protected static final int EVENT_BUTTON2 = EVENT_BUTTON + 2;
    
private BroadcastReceiver ReceivePeripheral = new BroadcastReceiver()
{
    @Override
    public void onReceive (Context context, Intent intent)
    {
        SendMessageToUnity("onReceive");
        
        try {
            Log.d("TEST", "ONReceive");

            CommunicationIntent info =
                CommunicationIntent.intentToCommunicationIntent(context, intent);
            
            switch (info.getIdEvent())
            {
                case EVENT_BUTTON1:
                    Toast.makeText
                    (
                        context,
                        "Intent peripheral button 1 " + info.getValue("action"),
                        Toast.LENGTH_LONG
                    ).show();
                    
                    SendMessageToUnity("onReceive EVENT_BUTTON1");
                    break;

                case EVENT_BUTTON2:
                    Toast.makeText
                    (
                        context,
                        "Intent peripheral button 2 " + info.getValue("action"),
                        Toast.LENGTH_LONG
                    ).show();
                    
                    SendMessageToUnity("onReceive EVENT_BUTTON2");
                    break;

                default:
                    break;
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
};

And this seems not to be working…

The receiver is registered in the onStart method:

@Override
protected void onStart ()
{
    IntentFilter iFilter = new IntentFilter("amialcance.accessiblegame");
    instance.registerReceiver(ReceivePeripheral, iFilter);
    
    super.onStart();
    
    SendMessageToUnity("Started");
}

and the AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.company.pushTest"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="14"
        android:targetSdkVersion="20" />

    <application
        android:allowBackup="true" >
        
        <activity android:name=".PushButtonPlugin"
             android:label="@string/app_name"
             android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
	        <intent-filter>
	            <action android:name="android.intent.action.MAIN" />
	            <category android:name="android.intent.category.LAUNCHER" />
	        </intent-filter>
	    </activity>
    
    </application>

</manifest>

I have lost a lot of time with this… Anyone can help me?

Thanks!
