What is meant by "activity" in Android Studio?
I think I have done everything correctly. In order to test a debug version of an APK file in Android Studio, I understand I had to build a key store and give it a set variables. I did that from the commandline and in the Android Studio I used "Generate Signed Bundle or APK" to assign this .JKS file to the project.
I only mention this because it was the last thing I did before a successful build. I have the Android Studio successfully recognising my physical device in the Device Manager for testing. I also have it set to what I believe is the proper Active Build Variant.
The error I get is:
Could not identify launch activity: Default Activity not found Error while Launching activity Failed to launch an application on all devices.
What is this "activity" they are speaking of? What is a "Default Activity" in Android Studio?
Also, since this is my first APP. Is there a simple "Hello World" Debug app I can step through the building process of in Android Studio? Maybe there is a step along the way that I am overlooking.
