Problem in manifest application tag when we giveandroid:name="" app crash

Question

I used firebase offline capability in my app. It will add name tag in manifest file. When I add name tag the app will crash. I search it but no solution can be found.

Here is the manifest code

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="fsd.finalyearproject.nut.rozgar.rozgar">
