我可以在 android 中同时在两个应用程序中使用陀螺仪传感器吗？

Question

I want to use the gyroscope sensor in Android simultaneously in two different applications. I know that it's not required to bind the sensor in an application so I am assuming that we can use the gyroscope sensor in two different applications at the same time.

Can someone please point me in the right direction?

Answer 1

You can't use anything in two applications at the same time because Android OS prevents applications to work after an app loses its focus. But you can do it with 2 services and you can fetch data from the application when needed.

For example:

//App1
    //Service1
        //read gyro data, write it to application space(db or sharedpreferences)

    //App1 Activity
        //read data from application space and show it to the user

//App2
    //Service2
        //read gyro data, write it to application space(db or sharedpreferences)
    //App2 Activity
        //read data from application space and show it to the user

So you can have continuous data flow at the same time for each app.
