1. Activity请求权限 (Android6.0 = TargetAPI 23)

 if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)
                != PackageManager.PERMISSION_GRANTED) {//申请数据存储权限
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                    WRITE_EXTERNAL_STORAGE_REQUEST_CODE);
        }

2. 请求回调(授权或者拒绝)

 @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == WRITE_EXTERNAL_STORAGE_REQUEST_CODE) {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // Permission Granted 授权
            } else {
                // Permission Denied 拒绝
            }
        }
    }

3. Fragment请求权限

在Fragment中申请权限，不要使用ActivityCompat.requestPermissions, 
直接使用Fragment的requestPermissions方法，
否则会回调到Activity的onRequestPermissionsResult
