main activity gets white screen after slpash screen

I am creating an app in which i have created navigation drawer in one project and splash screen and one more random activity in second project. So I am trying to merge them. I have set the splash screen and random acitvity so merge have done properly.

Then I have set a button on random activity which redirects to main activity(here is homeActivity) but when I click on button its get white screen.

In homeAcitivity I have used navigation Drawer as I already mentioned so how can I solve the white screen issue on mainActivity??? I have seen some question here but I am not getting my solution....

using android studion 2.1.2 gradle version 2.10

Thanks

Solution

  • Finally after reviewing all other layout files related to main activity we got the solution for our problem

    solution is Changed in content_main.xml in desing view From AppTheme.NoActionBar to AppTheme and its showing activity in normal way...
