Are you using the “dev app” that is available on d.defold.com? (Or any other prebuilt Defold Android app?) It’s important to remember that native extension code is not “hot reloadable” or automatically deployed when you do “Build & Launch” with a running Android app as a target. You can however bundle your app once with the native extension and install on your Android device then use it as a target if you want to hot reload/build&launch with Lua and collection changes. Makes sense?
Wow, that’s great news, thanks! And thanks for the explanations! The reason I couldn’t install the .apk was because I already had another defold project on my phone and the two were conflicting for some reason.
