Opening activity from notification issued from service not working - push-notification

Question

I'm having a really bad time trying to open an activity from a notification my app is receiving from an application server I've set up. I have an android service that is run when a user logs into the app server, which handles receiving notifications. An activity called "Notifications" is supposed to be launched when the user clicks on the notification. The relevant code on the Android service:
int requestID = (int) System.currentTimeMillis();
Intent intent = new Intent();
intent.setComponent(new ComponentName(this, Notifications.class));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
//intent.putExtra("json", message);
PendingIntent pintent = PendingIntent.getActivity(this, requestID, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Then, after setting title and text for the notification:
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.plus)
.setContentTitle(title)
.setContentText(caption)
.setContentIntent(pintent)
.setLights(Color.BLUE, 1000, 1000)
.setVibrate(new long[] {0, 100, 100, 100});
NotificationManager mNotifyMgr =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
mNotifyMgr.notify(100, mBuilder.build());
The Notifications Activity in its entirety:
package com.myapp;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
public class Notifications extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notifications);
}
}
I have declared my Activity in the manifest file:
<activity
android:name=".Notifications"
android:label="#string/title_activity_notifications"
android:screenOrientation="portrait"
android:launchMode="singleTask"
android:taskAffinity=""
android:excludeFromRecents="true">
</activity>
What I am baffled about is that this specific activity will not open - I have tried setting it to open other activities and it works just fine then. Here is my logcat from when the precise moment I click on the notification:
04-26 23:43:33.301: D/StatusBar(896): Clicked on content of 0|com.myapp|100|null|10107

04-26 23:43:33.703: D/PhoneStatusBar(896): disable: < expand icons* alerts system_info* back home recent clock search >
Does it have something to do with the com.google.android.gms.games.Notifications text seen in the logcat? I'm running Android 5.1 on a Nexus 5.
Edit
So, I renamed the Activity to Notification and now all is well. I don't have a suitable explanation as to why it fails in the first place, so I'm going to leave this question up until/if someone may adequately explain what was happening in the first place, since I'm not about to spend any more time on it now.

Answer 1

It is pretty clear what happened. You have this code to set up the notification Intent:
intent.setComponent(new ComponentName(this, Notifications.class));
You must have imported the package com.google.android.gms.games so that the compiler uses com.google.android.gms.games.Notifications instead of your own class. When you changed the name of your class, the compiler was able to choose the correct class. Have a look at your import statements.
