Answer 1

That package name always refers to the package name that Google Play console uses for your Application Id.

It used to be the one in the manifest.xml of your application

<manifest package="tv.potato.baked"
          xmlns:android="http://schemas.android.com/apk/res/android">

    <application
        android:allowBackup="true"
        android:label="@string/app_name"
        >
    .
    .

But on (recent versions?) of Android Studio, this package is ignored, and the one defined in your application module's build.gradle is the one used:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"

    defaultConfig {
        applicationId "tv.potato.baked"
        minSdkVersion 21
        targetSdkVersion 25
        versionCode 1
        .
        .
        .

That package name also defines your app name in the playstore (look at the url), so once the app has been published for the first time it cannot be changed.
