[코틀린코드연습장] Permissions.

내가 과연 permission을 사용하는 앱까지 만들어 볼수 있을까?

심란하구만 

[Manifest.xml]

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>

class MainActivity : AppCompatActivity() {

    var pm = arrayOf(
        Manifest.permission.SEND_SMS,
        Manifest.permission.RECEIVE_SMS,

        Manifest.permission.WRITE_CONTACTS,

        for (permisson in pm) {

            var chk = checkCallingOrSelfPermission(permisson)
