    To finish the setup of this demo, do the following:

1. Download google_services.json from your Firebase project.
2. Update "Remote Notifications Config File" path in Android exporter (this can be different for debug and release)
   to point to that json file.
3. Add image and sound resources by adding the following to "Extra Android Raw Resources" in Projucer:

../../Assets/Notifications/images/ic_stat_name.png
../../Assets/Notifications/images/ic_stat_name2.png
../../Assets/Notifications/images/ic_stat_name3.png
../../Assets/Notifications/images/ic_stat_name4.png
../../Assets/Notifications/images/ic_stat_name5.png
../../Assets/Notifications/images/ic_stat_name6.png
../../Assets/Notifications/images/ic_stat_name7.png
../../Assets/Notifications/images/ic_stat_name8.png
../../Assets/Notifications/images/ic_stat_name9.png
../../Assets/Notifications/images/ic_stat_name10.png
../../Assets/Notifications/sounds/demonstrative.mp3
../../Assets/Notifications/sounds/isntit.mp3
../../Assets/Notifications/sounds/jinglebellssms.mp3
../../Assets/Notifications/sounds/served.mp3
../../Assets/Notifications/sounds/solemn.mp3

4. Set "Remote Notifications" to enabled in Projucer Android exporter.

To verify that remote notifications are configured properly, go to Remote tab in the demo and press "GetDeviceToken"
button, a dialog with your token (also printed to console in debug build) should show up.


The following steps are only necessary if you have a custom activity defined:

5. Ensure that its launchMode is set to "singleTop" or "singleTask" in Android manifest. This is the default behaviour
   in JUCE so you only need to do it if you have custom Android manifest content. You can do it from Projucer by
   ensuring that "Custom Manifest XML Content" contains:

<manifest>
<application>
<activity android:launchMode="singleTask">
</activity>
</application>
</manifest>

6. Ensure that you override onNewIntent() function in the same way as it is done in JuceActivity.java:

package com.rmsl.juce;

import android.app.Activity;
import android.content.Intent;

//==============================================================================
public class JuceActivity   extends Activity
{
    //==============================================================================
    private native void appNewIntent (Intent intent);

    @Override
    protected void onNewIntent (Intent intent)
    {
        super.onNewIntent(intent);
        setIntent(intent);

        appNewIntent (intent);
    }
}
