@henninghall Hi, can you review this mr please

Hi @Ali-Oliaee , thanks for you contribution!

What issue does this solve? What react native version/expo version etc?

It has been up for discussion before: #726

Hi again @henninghall,

I checked the discussion you mentioned, I didn't find any recursion or namespace support from react native team or Gradle,
but I think these changes are necessary because I have no plans to update my project versions and I'm sure we have similar circumstances for other projects in production level.

This issue is related to Gradle's namespace support, you don't need to specify the package name in your Android manifest file, but you must declare it in the build.gradle file, otherwise you will get the following error:

Namespace not specified. Please specify a namespace in the module's build.gradle file like so:

android {
    namespace 'com.example.namespace'
}

And this update was applied from Gradle 7.3.0 above.

If you have any documentation about Gradle future plans or alternative solutions, please share with me, we can add another restriction to these PR changes and set a minimum and maximum for Gradle version support.
I have now controlled this problem with the patch package but I think it's better to set these changes on package level.

What do you think?
