context.getContextResolved 응용 프로그램이 중지되었습니다.

내 응용 프로그램에 문제가 있습니다. 쿼리를 실행하려고하는데 매번 앱이 중지됩니다. 이 쿼리는 실행 쿼리를 시도하는 동안 발생합니다. 내가 안드로이드에서 배우고 는 프로 3 책은, 그러나이 책에 제시된 코드는 사용되지 않습니다 :context.getContextResolved 응용 프로그램이 중지되었습니다.

package com.example.contactsabuout; 

import android.net.Uri; 
import android.os.Bundle; 
import android.provider.Contacts; 
import android.provider.ContactsContract; 
import android.app.Activity; 
import android.database.Cursor; 
import android.util.Log; 
import android.content.Context; 
import android.view.Menu; 
import android.view.View; 
import android.widget.TextView; 

public class MainActivity extends Activity { 

    private static Context context; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     MainActivity.context = getApplicationContext(); 

     Log.v("INFO", "Completed: onCreate."); 
    } 

    public static Context getAppContext() { 
     return MainActivity.context; 
    } 

    public void doQuery(View view) { 

     Uri peopleBaseUri = ContactsContract.Contacts.CONTENT_URI; 
     Log.v("II","Button clicked."); 
     Log.v("II", "Uri for ContactsContract.Contacts: " + peopleBaseUri); 
     Context context = getAppContext(); 
     Log.v("II", "Got context: " + context); 
     Cursor cur; 
     Log.v("II", "Created cursor: cur"); 
     cur = context.getContentResolver().query(peopleBaseUri, null, null, null, null); 

    } 


    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.activity_main, menu); 
     return true; 
    } 
}

내가 안드로이드 배우려고 노력하고있어

정확히 Manifest 파일에이 위치를 배치 할 위치는 어디입니까? 답변 감사합니다. – Szymad

매니페스트 파일에 다음 권한을 추가하십시오.
