In order to catch BOOT_COMPLETED, is it enough just to register the BroadcastReceiver in the `AndroidManifest.xml`?

In order to catch android.intent.action.BOOT_COMPLETED events, is it enough just to register the BroadcastReceiver in the AndroidManifest.xml? like this:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.myDomain.myApp"
          android:installLocation="internalOnly">
    <!-- ... stuff ... -->
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <!-- ... stuff ... -->
    <application ...>
        <!-- ... stuff ... -->
        <receiver android:name=".bgServices.MyBootBroadcastReceiver">
        </receiver>
        <!-- ... stuff ... -->
    </application>
</manifest>

The BroadcastReceiver:

package com.myDomain.myApp.bgServices;

// imports ...

public class MyBootBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("my-log", "MyBootBroadcastReceiver.onReceive()");
        Toast.makeText(context, "YEAY!", Toast.LENGTH_LONG).show();    
    }
}

I'm asking because I'm sending:

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -n com.myDomain.myApp/.bgServices.MyBootBroadcastReceiver

But nothing happens.

(and I run the app, not just pushing it to the device)
