我想使用EasyPreferences库：https://github.com/Pixplicity/EasyPreferences

但出现此错误：请在Application类onCreate中调用Builder.setContext（）。build（）

PrefsApplication.java 

  package ir.korandco.irkhoone_co_app.utility;

import android.app.Application;
import android.content.ContextWrapper;

import com.pixplicity.easyprefs.library.Prefs;

public class PrefsApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        // Initialize the Prefs class
        new Prefs.Builder()
                .setContext(this)
                .setMode(ContextWrapper.MODE_PRIVATE)
                .setPrefsName(getPackageName())
                .setUseDefaultSharedPreference(true)
                .build();
    }

}

t = Prefs.getString（SAVED_TOKEN，＆＃34;不可用＆＃34;）;

但遇到了这个错误：

请在Application类onCreate

中调用Builder.setContext（）。build（）

最有可能的是，您还没有在AndroidManifest.xml中定义您的应用程序类

<application
    android:name="ir.korandco.irkhoone_co_app.utility.PrefsApplication"
