I just had a look at your project:
The license key at the Facebook plugin definition in your Home.qml is the license key of the FacebookSample. As I mentioned earlier, you would need to set your own license key that matches “com.donegames.apps.neariou” version “1” and includes the Facebook plugin. You can create one here: Generate License Key
At least a V-Play indie license is required in order to generate license keys for using the plugins.
I was able to run your application on my android phone without a crash after I set a valid license key.
