逆向魔改安卓7.0/7.1 systemUI添加"关闭所有程序"广播报错
本帖最后由 tyc600 于 2023-6-25 06:55 编辑参考网上的思路Android 7.1.1 Framework 修改记录(二) 清理近期任务并排除白名单,想要给安卓7.0/7.1 systemUI添加"关闭所有程序"广播, 我没有系统源代码编译systemUI,因为代码不多,所以采用的直接模仿smali代码的方式在com/android/systemui/下新建了一个新建了一个名为CloseAllAppsReceiver的class,代码如下第一个代码段。第二段代码为在MT管理器转换为java后的代码,然后在AndroidManifest里面注册广播第三段代码。没有在frameworks的AndroidManifest.xml新增protected-broadcast android:name="close.all.apps.by.external.intent". 声明这个广播保护的话,就只允许系统应用调用了吧,计划通过第三方应用(tasker)发送意图来一键执行"关闭所有应用程序",现在魔改后的systemUI,在tasker执行意图后,直接报"systemUI停止工作,关闭应用"。有7.0/7.1的大神,能不能试试整合我的smali代码到你的systemUI,帮忙看看smali代码是否有问题。另外参考博文里面的调用是从外部第三方调用这个systemUI里面的广播的吧?模仿原生系统里声明一个允许被第三方调用的意图广播, 是我的smali代码有问题,还是有其他额外的步骤遗漏,还请各位帮忙看看,谢谢了。
(另外tasker已经魔改过了添加了uses-permission android:name="android.permission.REMOVE_TASKS,并且可以通过内置的java代码能力,成功执行关闭任务的操作,所以第三方应用的关闭任务权限是没有障碍的)
