Android SDK 35 , AGP 8.0 Bug

[huangzhewei]

Build info

Android Studio Otter | 2025.2.1

• ObjectBox version: [ 4.0.1 or 5.0.1]
• OS: [ Android 15 SDK 35 ]
• version: [
  'com.android.tools.build:gradle:8.1.0'
  https://services.gradle.org/distributions/gradle-8.0-bin.zip
  ]
• Device/ABI/architecture: [ One plus 8T | arm64-v8a | x86-64 ]

Actual behavior

TODO Tell us what actually happens.

I originally wanted to use ObjectBox with SDK version 34 and AGP version 7.4, but Google now requires new applications to be uploaded with SDK version 35, and SDK version 35 requires AGP 8.0 or higher to work. However, after upgrading to SDK 35, ObjectBox stops working, displaying an error message that MyObjectBox cannot be found, and the generated entity classes cannot be found either. If I revert to SDK version 34, it works fine, but Google requires SDK 35. Therefore, I need your help.

Code

TODO Add a code example to help us reproduce your problem.

Code

MyObjectBox.builder().androidContext(BWNApplication.applicationContext).build();

public static GoogleOrder getGoogleOrder(GoogleOrder googleOrder) {
        try {
            BoxStore boxStore = init();
            if (boxStore != null && !boxStore.isClosed()) {
                Box<GoogleOrder> box = boxStore.boxFor(GoogleOrder.class);
                return box.query()
                        .equal(GoogleOrder_.productToken, googleOrder.productToken.getBytes())
                        .build().findFirst();
            }
        } catch (Exception e) {
        }
        return null;
    }

public static List<ComicChapter> getcomicDownOptionList(long comic_id) {
        try {
            BoxStore boxStore = init();
            if (boxStore != null && !boxStore.isClosed()) {
                Box<ComicChapter> box = boxStore.boxFor(ComicChapter.class);
                List<ComicChapter> joes = box.query()
                        .equal(ComicChapter_.comic_id, comic_id)
                        .equal(ComicChapter_.downStatus, 1)
                        .build().find();
                return joes;
            }
        } catch (Exception e) {
        }
        return new ArrayList<>();
    }

There are no known issues with Android Gradle plugin version 8 or compiling with Android SDK 35. Actually version 8.0.2 or higher of the plugin is even required. So this is likely an issue with your project setup.

Did you make sure to rebuild your project to re-generate the MyObjectBox class?

If you share a minimal example project to reproduce this I can try to help.
