E/WM-WorkerFactory: 无法实例化 com.isopod.gateauth.UnifyIDAPIHandler$ModelTrainer
E/WM-WorkerFactory: Could not instantiate com.isopod.gateauth.UnifyIDAPIHandler$ModelTrainer
所以我尝试使用标准 android 工作库安排任务，但我得到以下错误跟踪

我正在使用标准工作库。我看到其他用户在尝试注入自定义初始化程序时遇到了这个问题，但我相信我使用的是默认库，它应该能够自行正确初始化
这是我的应用程序级别的依赖项 build.gradle:
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'id.unify.sdk:sdk-gaitauth:1.3.8'
implementation "androidx.work:work-runtime:2.4.0"
implementation 'com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava'
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}
这是我正在尝试使用的 class 的代码
public class ModelTrainer extends Worker {
public ModelTrainer (Context context, WorkerParameters params){
super(context, params);
}
@NonNull
@Override
public Result doWork() {
try {
if (curStatus == GaitAuthStatus.READY_TO_TRAIN) {
gaitModel.train();
curStatus = GaitAuthStatus.TRAINING;
} else if (curStatus == GaitAuthStatus.TRAINING) {
gaitModel.refresh();
}
} catch (GaitModelException e) {
e.printStackTrace();
return Result.failure();
}
if (gaitModel.getStatus() == GaitModel.Status.READY) {
curStatus = GaitAuthStatus.READY;
} else if (gaitModel.getStatus() == GaitModel.Status.FAILED) {
return Result.failure();
}
return Result.success();
}
}
这是我开始工作的代码
WorkRequest trainModelRequest = new OneTimeWorkRequest.Builder(ModelTrainer.class).build();
WorkManager.getInstance(mainActivity.getApplicationContext()).enqueue(trainModelRequest);
mainActivity.addTextToScreen("Model training started");
还值得注意的是，我收到了一堆看起来很奇怪的消息 android 工作室 运行 日志：

任何人都可以告诉我可能发生的事情吗？我很困惑。我几乎遵循了 android 文档中的设置指南和示例，所以如果我遇到这个问题，我相信很多其他人也会遇到这个问题
引用可爱的 u/Zhuinden 在 reddit 上的回答，
如果这是一个 worker，您需要有一个构造函数来获取 Context、WorkerParameters，并且没有其他参数。就这两个。
在您的情况下，问题是您的 class 是内部 class，但在 Java 中，这意味着它也有对其父级的引用。您需要将其定义为静态 class
确实，在 class 定义中添加 static 解决了这个问题，但由于我想通过它传递数据，所以我将其设为独立的 public class 并使用了 workmanager 数据class 传递参数
