我也给注入事件许可 有没有办法让一个应用系统的权限。

I also give the inject event permission is there any way to give a application system permissions.

推荐答案

只有作为固件的一部分应用程序（例如，通过固件签名密钥签名的）可以按住 INJECT_EVENTS 许可。如果你正在做自己的设备或固件，这将是相关的。如果要创建一个普通的SDK应用程序，你不能注入事件。

Only applications that are part of the firmware (i.e., signed by the firmware signing key) can hold the INJECT_EVENTS permission. If you are making your own device or firmware, this will be relevant. If you are creating an ordinary SDK application, you cannot inject events.
