由于android 11以上版本对于读写权限的进一步限制，安装的apk获取权限的流程又加了一步，对于客户来说多半步也算复杂，Android 保存/读取本地SD卡文件（兼容Android 13）
根据之前的经验，在安装流程后打开全部权限即可。

验证结构显示：
mDefaultPermissionPolicy.grantAppRuntimePermissions(packageName);为获取除android.permission.MANAGE_EXTERNAL_STORAGE外的所有权限
为了解决android.permission.MANAGE_EXTERNAL_STORAGE，需要额外添加enableManageExternalStorage(packageName, resAppId);
