Android 6.0的权限问题

Android 6.0的权限获取不同于别的版本，具体的实例如下：

if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS)
        != PackageManager.PERMISSION_GRANTED) {
    //申请READ_CONTACTS权限
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_CONTACTS},
            READ_CONTACTS_REQUEST_CODE);
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    doNext(requestCode, grantResults);

}

private void doNext(int requestCode, int[] grantResults) {
    if (requestCode == READ_CONTACTS_REQUEST_CODE) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // Permission Granted
            LogUtils.i(TAG,"获取了读取通讯录的权限");
            creditCheckTask.getAndSendContact();
        } else {
            LogUtils.i(TAG,"没有获取读取通讯录权限");
            // Permission Denied
            return;
        }
    }

}
