  • Uninstall_app
    静默批量卸载安卓非内置App源码,传统的安卓应用卸载会直接转跳到系统的应用详情界面点击卸载才能一个个的卸载,本例子卸载应用的时候不需要弹出应用管理界面直接静默卸载手机非内置应用,用户体验良好并且支持选择多个app一起卸载,但是运行的时候会申请Root权限,有Root权限才能卸载。(PS.另外尝试了一下卸载360,未果,说明并不是万能不过卸载普通的app绰绰有余了)默认编译版本4.2.2编码GBK源码有注释。(Silent batch uninstall an Zhuofei built-in app source and traditional Android application uninstall will turn directly jump to the system application details screen, click the uninstall it before one of the unloading, this example to uninstall applications don t need pop-up application management interface directly silent uninstall mobile non built should be used, user experience good and support more than one app selection uninstalled together, but run time will apply root privileges, root privileges to uninstall. (Ps. in addition to try to uninstall the 360, failed to explain is not a panacea, but unloading ordinary app more than sufficient) default annotated version 4.2.2 GBK encoding source code compilation.)
