So my initial problem was resolved in an earlier thread, It turns out the SDK Manager required me to activate Administrator rights, regardless of my current administrator rights. Meh. Anyway, when I (Build Run) my application through unity, a window will pop up, prompting me to save my .apk file in my project folder, afterwards, another window will pop up, prompting me to 'Select an Android SDK root Folder'. Could anyone explain to me why this is happening? I've looked up guides to exporting your app, but no video displayed this window as mine will.
