紅米小米等手機在android6.0以下加了許可權管理，用android自身帶的checkpermisson方法時，永遠返回true，因此在獲取許可權為true時，加入判斷

錄音許可權：

 Log.e("MainActivity", "onPermissionGranted");
                    if (PermissionHelper.isAudioEnable()) {
                        Toast.makeText(MainActivity.this, "開始錄音操作", Toast.LENGTH_LONG).show();
                    } else {
                        DialogUtil.showPermissionManagerDialog(MainActivity.this, "錄音或麥克風");
                    }
