超级新手 - Android Studio 模拟器抛出 INSTALL_PARSE_FAILED_NO_CERTIFICATES 错误

Question

I'm literally on day one of learning some Android development. I downloaded the latest Android Studio on my Mac. Set it up. Walked through a small code example aaaand... it failed. I pushed the "play" button and it launches the emulator but then throws the error:

09/18 14:33:12: Launching 'app' on Nexus 5X API 29 x86.
Installation did not succeed.
The application could not be installed: INSTALL_PARSE_FAILED_NO_CERTIFICATES
APK signature verification failed.

There are several postings here that cover this error, but they are either very old and don't match anything I am looking at, or are a level of complexity that I don't really understand. The tutorial and stuff online all suggest that something this simple should just "work". I don't really know what to do.

Answer 1

Oh man ok I figured it out. NONE of these tutorials explain that you have to create a keystore. Including the tutorials that even walk through setting up Android Studio. So a fresh install requires you to go "Generate Signed Bundle/APK" and the wizard walks you through setting up a basic keystore.
