Hi,
Thanks for sharing AndroidManifest.xml file. You have integrated in properly but as I am going through with your Manifest file I will found two Service and two Receiver there, So If the notification is override by other service and receiver, that may be a reason you are unable to launch the unity application.
Will you please share more logs of Android logcat that will help me to exactly track the problem.
Let me know if more queries are concern.
Thanks
Vishnu Garg
