How to manually add permissions to an android app?

how can I add app permissions manually ?

For example, I want to add geo location permissions to the app

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />

but I haven’t implemented it yet and I don’t want to add the plugin just yet.

Is it possible to add those permissions during build (meaning, without manually editing the android manifest file which is automatically generated )?

Thanks, Haki.
