Negación de permisos al intentar acceder a contactos en Android

Estoy intentando tener acceso a los contactos en el dispositivo y después mostrarlos en una lista, sin embargo cuando intento tener acceso a ellos con un cursor, consigo un error que falto permisos para READ_CONTACTS pero he dado ya permisos en mi AndroidManifest .xml

Código donde accedo a Contactos:

• Obtener la dirección de correo electrónico del propietario de Android muy bien
• RecoverySystem.installPackage - / cache / recovery / command: open failed: EACCESS (permiso denegado) - falta de permiso después de actualizar Android a 4.3+
• ¿Cómo conceder permiso para la aplicación que se descarga desde la tienda de juegos?
• Permiso para leer datos de la tarjeta SD
• Privilegios elevados en la aplicación para Android

public void setupCursor() { Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null); while (cursor.moveToNext()) { String name = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); String number = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); Toast.makeText(this, name + ": " + number, Toast.LENGTH_SHORT).show(); } cursor.close(); } 

AndroidManifest.xml

 <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="io.github.brady131313.textback" > <uses-sdk android:minSdkVersion="15" android:targetSdkVersion="21"/> <uses-permission android:name="ANDROID.PERMISSION.READ_CONTACTS"/> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".ActivityMainSettings" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".ActivityContactSelect" android:label="Select Contacts"> </activity> </application> </manifest>
