android 工作室中的权限拒绝

Question

I want to create an android application which view phone contact in application and I wrote this code in my activity

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            requestPermissions(new String[]{Manifest.permission.READ_CONTACTS}, 1);
            requestPermissions(new String[]{Manifest.permission.WRITE_CONTACTS}, 1);
            requestPermissions(new String[]{Manifest.permission.READ_PHONE_STATE}, 1);
        }
Uri u = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
Cursor curs = getContentResolver().query(u, null, null, null, null);
btn_some.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                showContacts();
            }
        });

this code works fine with emulator but when I tried it on my phone it has stopped logcat message is

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.MyApplication/com.example.MyApplication.MainActivity}: java.lang.SecurityException: Permission Denial: opening provider com.android.providers.contacts.ContactsProvider2 from ProcessRecord{5b66da3 28379:com.example.MyApplication/u0a264} (pid=28379, uid=10264) requires android.permission.READ_CONTACTS or android.permission.WRITE_CONTACTS

and this is my Mainfest

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>

How can I run this application on my phone?
