title: Generate Signed APK isn't displayed in Android Studio
body: <p>I am on Android Studio 3.6.3 and in order to publish my App to the Playstore, I need to generate a signed APK. As I learned in multiple consultations of the internet, there should be the option in the Menu->Build-><em>generate signed APK</em>. It is not there. Also, I can't change my Build Variants, <em>'nothing to show'</em> is displayed. I found in an older answer to set my Keystore up in the <em>Project structure</em> section, which is no longer possible, at least for me. So I went to the <em>build.gradle</em>, set up my Keystore, imported the Android-Certificate put all my credentials there. <em>Error in line 58, Could not get unknown property 'meister'</em>, was the result.
  All options I found to generate this signed APK aren't working for me.
  I just don't know how to help me now, other than asking you.</p>
