super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button)findViewById(R.id.button);
name = (TextView)findViewById(R.id.textView2);
number = (TextView)findViewById(R.id.textView);
EnableRuntimePermission();
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, 7);

Toast.makeText(MainActivity.this,"CONTACTS permission allows us to Access CONTACTS app", Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(MainActivity.this,new String[]{
Manifest.permission.READ_CONTACTS}, RequestPermissionCode);
}

switch (RC) {
case RequestPermissionCode:
if (PResult.length > 0 && PResult[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(MainActivity.this,"Permission Granted, Now your application can access CONTACTS.", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(MainActivity.this,"Permission Canceled, Now your application cannot access CONTACTS.", Toast.LENGTH_LONG).show();

IDresultHolder = Integer.valueOf(IDresult) ;
if (IDresultHolder == 1) {
cursor2 = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + TempContactID, null, null);
while (cursor2.moveToNext()) {
TempNumberHolder = cursor2.getString(cursor2.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
name.setText(TempNameHolder);
number.setText(TempNumberHolder);
}
