谷歌(Google) Pixel 8/9 Pro(xl)如何获取 root 权限谷歌(Google)Pixel8/9Pro(xl)等系列手机破解后，会在你的init_boot.img同路径生成一个magisk_patched.img，把这个文件拷贝到adb目录下，稍后还得把它刷回手机，这样手机才能获得Root权限，因为安卓14、15以后的内核结构调整，和Pixel7及以下的6、5、4、3、2等系列手机破解稍微不一致。因为ROOT权限的获取，需要使用ROM中的内核文件，个人强烈建议在官网下载ROM，直接刷最新版，其他地方的ROM如果没有校验码，请自行斟酌是否使用。阅读详情

我用jetty跑的项目，在我本地，想做个用ireport打印功能，用的是Jaspersoft iReport Designer 4.5.1
项目中用的也是这个Jar包，在点击打印按钮额时候，跳转到controller里，向request里set相关参数，然后跳转到打印页面，页面代码

基于QT的华为网络摄像头二次开发第一次使用华为的网络摄像头并进行二次开发，网上关于QT对华为网络摄像头的二次开发的文章很少，基于项目的需求做了一些工作，特此记录。目标： 1、实时预览 2、手动控制录制视频 3、监听告警型号 4、实时获取元数据中的划定区域内的人数摄像头型号如下：准备工作：在购买摄像头后，应当在官网下载对应的开发资料，如果需要权限，则联系华为的技术支持人员。下载资料如下： SDC Development Kit Demo 8.0.T9 SDK DEMO下载地址：https://bbs.hua 阅读详情

这个可能是设置的问题吧，你可以参考一下finereport的打印设置，总的来说我感觉用下来还是finereport在打印这一块做的不错，不管是产品，还是文档，都比较清晰明了。

网上查了，讲是编译的时候版本不兼容造成的...但是小弟真心不是熟悉这个，第一次接触...
请各位大侠帮忙解决...不胜感激....
