Answer 1

için günlük kedi mi izin bölümüne yazılan fazla kelime burada

public void GetContacts(View view) { 

    Cursor cursor=getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null,null,null,null); 
    while (cursor.moveToNext()) 
    { 
     int nameIndex=cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME); 
     String name= cursor.getString(nameIndex); 
     Log.d("mainActivityContacts",name); 
    } 
} 

koymak için çalışıyorum manifest dosyasından - bazı izin eklemediniz gibi görünüyor Projenizi temizleyip i SDK 23 hedefliyorsanız tahmin tekrar

Answer 2

inşa çalıştım eğer

requires android.permission.READ_CONTACTS or android.permission.WRITE_CONTACTSn 

, örneğin bir Requesting Permissions at Run Time

eklemem gerekiyor: istisna belirtilen

// Here, thisActivity is the current activity 
if (ContextCompat.checkSelfPermission(thisActivity, 
      Manifest.permission.READ_CONTACTS) 
    != PackageManager.PERMISSION_GRANTED) { 

// Should we show an explanation? 
if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, 
     Manifest.permission.READ_CONTACTS)) { 

    // Show an expanation to the user *asynchronously* -- don't block 
    // this thread waiting for the user's response! After the user 
    // sees the explanation, try again to request the permission. 

} else { 

    // No explanation needed, we can request the permission. 

    ActivityCompat.requestPermissions(thisActivity, 
      new String[]{Manifest.permission.READ_CONTACTS}, 
      MY_PERMISSIONS_REQUEST_READ_CONTACTS); 

    // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an 
    // app-defined int constant. The callback method gets the 
    // result of the request. 
} 
}
