私はアンドロイドの初心者です。私はudemyのコースを続けています。私は解析を使用しようとしたが、コードを実行しようとするたびにエラーが出る。相続人は解析クラスのコード：構文解析を使用してログインしようとしてエラーが発生しました
import android.app.Application;
import com.parse.Parse;
import com.parse.ParseACL;
public class StarterApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
// Enable Local Datastore.
Parse.enableLocalDatastore(this);
// Add your initialization code here
Parse.initialize(new Parse.Configuration.Builder(getApplicationContext())
.applicationId("4e188aaea9fd210545126d11e6dc4b2463265310")
.clientKey("00f12c54779ba75af4d6deb7c599c5de77ddd47a")
.server("http://ec2-13-59-193-44.us-east-2.compute.amazonaws.com:80/parse/")
.build()
);
//ParseUser.enableAutomaticUser();
ParseACL defaultACL = new ParseACL();
defaultACL.setPublicReadAccess(true);
defaultACL.setPublicWriteAccess(true);
ParseACL.setDefaultACL(defaultACL, true);
}
}
