java - 放大 appsync-datastore Android Studio 上的 java.lang.NoClassDefFoundError

问题描述

我是 AWS Amplify 的新手，我正在尝试遵循此处的文档。使用以下代码一切正常：

 try {
     Amplify.addPlugin(new AWSApiPlugin()); //Giving error when inserted
     Amplify.addPlugin(new AWSDataStorePlugin());
     Amplify.configure(getApplicationContext());

     Log.i("Tutorial", "Initialized Amplify");
 } catch (AmplifyException e) {
     Log.e("Tutorial", "Could not initialize Amplify", e);
 }


Todo item = Todo.builder()
   .name("Build Android application")
   .description("Build an Android application using Amplify")
   .build();

 Amplify.DataStore.save(item,
     success -> Log.i("Tutorial", "Saved item: " + success.item().getName()),
     error -> Log.e("Tutorial", "Could not save item to DataStore", error)
 );

但是当我添加Amplify.addPlugin(new AWSApiPlugin());里面try/catch并再次重新运行应用程序时，它总是崩溃并给我这个错误。

请注意，我已经配置了放大并将所有必要的文件推送到云端。
