전원케이블 연결시 토스트 화면 띄우기 질문

Question

MyReceiver.java

public class MyReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
       if(Intent.ACTION_PACKAGE_CHANGED.equals(intent.getAction())){
           Toast.makeText(context,"굿굿",Toast.LENGTH_SHORT).show();

       }
    }
}

MainActivity.java

public class MainActivity extends BaseActivity {
    private BroadcastReceiver mReceiver;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mReceiver = new MyReceiver();

    } 

    @Override
    protected void onResume(){
        super.onResume();
        IntentFilter filter = new IntentFilter();
        filter.addAction(Intent.ACTION_PACKAGE_CHANGED);
        registerReceiver(mReceiver,filter);
    }
@Override
protected void onPause(){
        super.onPause();
        unregisterReceiver(mReceiver);
      }
} 

AndroidMainfest.xml

 <receiver
            android:name=".MyReceiver"
            android:enabled="true"
            android:exported="true" >
            <intent-filter>
                <action android:name="android.intent.action.ACTION_POWER_CONNECTED" />
            </intent-filter>
        </receiver>

targetSdkVersion 27 입니다  

이렇게 코딩 했는데 충전케이블 꽂아도 아무런 반응이 없더라구요 ㅠㅠ 왜 그럴까요 ㅠ

그리고 Toast 대신에 액티비티 화면 띄워줄라면 어떻게 해야되나요??

리시버랑 액티비티에 인텐트 액션을 잘못쓰셨네요

ACTION_PACKAGE_CHANGED -> ACTION_POWER_CONNECTED
