Native Android with Unity development

Hi Friends,

Suggest me to develop android application (Android Studio) with support of Oculus Gear VR (Develop separate project in Unity android )

I have added below meta-date in manifest file (Android Studio) to trigger the Oculus Mode 
<meta-data android:name="com.samsung.android.vr.application.mode" android:value="vr_only"/>
Unfortunately Oculus mode is automatically starts at launcher mode. But I need to integrate the Oculus device after the login page complete.

Kindly suggestion me to develop further steps.

Note :In Developer Mode is working fine as excepted can able to access android login page but in distribution mode it is not working the same.
