Android studio error: "Cannot resolve symbol 'XX'"

[inmess]

I'm new to native development, using 'npx create-react-native-library@latest' to initialized a module. However, I got stuck in the very first step...

I really have no clue whether it is about my sys environment (something like jdk version, node version or gradle) or a bug of this lib (which I don't think so)...

BTW gradle really did mess me up a lot before this...

Anyway, literally my project was not changed at all, error occurred right after I init it and open android/ folder in Android Studio.

System: Macos with M1 chip;
JDK version: 17 (I do have two different versions on my computer, jdk-11 is the one default in PATH, 17 is the one installed by AS);
react-native version: 0.72.1;
node version: 16.19.0

Hey, could you try opening example/android folder instead of the root level /android folder? This seems like to be the issue. Once you do this, you can switch to the Android tab and select your project to develop. Please make sure to take a look at the CONTRIBUTING.md file that is generated with your project. Line 58 should tell:

To edit the Java or Kotlin files, open `example/android` in Android studio and find the source files at `react-native-awesome-library` under `Android`.

No problem 😅 and no you don't have to copy anything. All your changes should be reflected to the source files under the root level /android folder. You can verify it by checking the git changes.

I don't get how this answers the question. example/android is a different directory to android/ and aren't even nested under each other. So how can they see each others project files? example/android contains the module files while android/ only contains the MainActivity and MainApplication files.

@CyberCyclone The example/android is also a gradle project. React Native links your android module to the example app so your module is added to the app as a gradle dependency. When you open your app in Android Studio, go to the gradle dependencies, find your lib, and edit it; the changes you make are within your fs. So the answer is Android Studio + React Native + Gradle handling those stuff for you.

Thanks @satya164 and @atlj, that makes sense. Thanks for the explanation.
