E / WM-WorkerFactory：无法实例化com.isopod.gateauth.UnifyIDAPIHandler $ ModelTrainer

如何解决E / WM-WorkerFactory：无法实例化com.isopod.gateauth.UnifyIDAPIHandler $ ModelTrainer

所以我正在尝试使用标准的android工作库安排任务，但出现以下错误跟踪

E/WM-WorkerFactory: Could not instantiate com.isopod.gateauth.UnifyIDAPIHandler$ModelTrainer
    java.lang.NoSuchMethodException: <init> [class android.content.Context,class androidx.work.WorkerParameters]

E/WM-WorkerWrapper: Could not create Worker com.isopod.gateauth.UnifyIDAPIHandler$ModelTrainer

我正在使用标准工作库。我已经看到其他用户在尝试注入自定义初始化程序时遇到此问题，但是我相信我正在使用默认库，该库应该能够自行正确初始化

这是我在应用程序级别build.gradle中的依赖项：

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'
}

这是我要使用的类的代码

 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 studio运行日志：

有人可以给我一些想法吗？我很困惑。我几乎遵循了android文档中的设置指南和示例，因此，如果我遇到此问题，我肯定还有很多其他问题

解决方法

可爱的u / Zhuinden在reddit上引用答案，

如果这是一个工作程序，则需要有一个使用Context，WorkerParameters和其他参数的构造函数。只是这两个。

在您的情况下，问题在于您的类是一个内部类，但是在Java中，这意味着它也引用了其父类。您需要将其定义为静态类

的确，在类定义中添加了static可以解决此问题，但是由于我想通过它传递数据，因此我将其设置为独立的公共类，并使用workmanager数据类传递参数
