在清单中设置的 Android 自定义应用程序类不适用于 ClassCastException

Question

I don't know what is problem, because in my other projects it is work. I'm use custom application class and register it in my manifest file:

package ru.jooogle.sunshine.admin_pc.sunshine_reborn;

import android.app.Application;
import android.content.Context;
import ru.jooogle.sunshine.admin_pc.sunshine_reborn.model.network.NetworkService;

    public class SunshineApplication extends Application {
        private NetworkService networkService;

        public static SunshineApplication get(Context context) {
            return (SunshineApplication) context.getApplicationContext();
        }

        public NetworkService getNetworkService() {
            if (networkService == null) {
                networkService = new NetworkService();
            }

            return networkService;
        }
    }

And manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="ru.jooogle.sunshine.admin_pc.sunshine_reborn">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:name=".SunshineApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".SunshineActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

In Activity onCreate i do:

SunshineApplication sunshineApplication = SunshineApplication.get(this);

and i get ClassCastException:

java.lang.ClassCastException: android.app.Application cannot be cast to ru.jooogle.sunshine.admin_pc.sunshine_reborn.SunshineApplication

I don't know what is it, help, please.
