Android Permissions

Hey Guys ,
Is there any way that i could request for Android.permissions,WRITE_EXTERNAL_STORAGE and android.permissions.READ_EXTERNAL_STORAGE before the splash screen ,

Like all other apps do , They ask for permissions which will be required in the app .
Iam having this Xapk Validation Failed Error , Every Time when i Launch the App Instead of its usual splash screen we have another Screen with this Error , if i minimize the app , i have a permission Request for Storage , When i allow it and close the app from background and restart it , it says verfying download and starts working ,

Now i need that requesting permission Dialog to be the first thing that this app should ask for .
Is there any way that we could achieve this ,

Thank You
