[英]How to get action that android application is trying removed/uninstalled from device
When user want to uninstall app from android device, I want user uninstall button click event for that application. 当用户想要从Android设备卸载应用程序时,我想要该应用程序的用户卸载按钮单击事件。
I am getting event of application is removed from device, but I want to show pop-up before application is removed. 我正在从设备中删除应用程序的事件,但我想在删除应用程序之前显示弹出窗口。 I am trying to achieve same like doing in 'App Lock' application.
我正在尝试实现与“App Lock”应用程序相同的功能。
Here is my code to get application removed event through broadcast receiver. 这是我通过广播接收器获取应用程序删除事件的代码。 But I am totally blank about uninstall button click or before pop-up click.
但是关于卸载按钮单击或弹出单击之前,我完全是空白。 Please guide me in right direction.
请指导我正确的方向。
Thanks in advance. 提前致谢。

Please try to get the top activity in the task via ActivityManager
, and check if it is the uninstall activity. 请尝试通过
