Unity - Android Broadcast receiver not been called

Question

I'm using Unity to set alarms for a project. (Usually wouldn't use Unity but it is a requirement for different reasons). I've written an alarm like this, and this method is called from Unity with a parameter of 5:

public void SetAlarm (float time)
    {
        Intent intent = new Intent(context, AlarmClockPlugin.class);
        intent.setAction("ALARM_INTENT");
        PendingIntent pending = PendingIntent.getBroadcast(context,0,intent,0);
        alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (long) (1000 * time), pending);
}

This alarm class also inherits from BroadcastReceiver and overrides the OnReceive method like this:

@Override
    public void onReceive(Context context, Intent intent) {
        PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
        PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "");
        wl.acquire();

        // Write toast text for now
        Toast.makeText(context,"Broadcast received",Toast.LENGTH_LONG).show();

        wl.release();
    }

I register the broadcast receiver in the manifest like this:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.tombuild.myapp">
<uses-permission android:name="android.permission.WAKE_LOCK"/>

<application
    android:allowBackup="true"
    android:label="@string/app_name"
    android:supportsRtl="true">
    <receiver android:process =":remote" android:name="com.tombuild.myapp.AlarmClockPlugin">
        <intent-filter>
            <action android:name="ALARM_INTENT"/>
        </intent-filter>
        </receiver>
</application>

</manifest>

But unfortunately the onReceive is not been called - no toast notification pops up at all after the 5 second duration, why is this?

I'm not familiar with Unity, but there obvious differences with Unity and Android Studio from the code you have posted, for example no Activity in the manifest. Why not try a simpler example in your setAlarm method.

    ...
    Intent intent = new Intent();
    intent.setAction("com.tombuild.myapp.ALARM_INTENT");
    sendBroadcast(intent);
    ...

And just put a Toast in the onReceive method.

There is a very simple tutorial on BroadcastReceivers on TutorialsPoint, which got me started.
