Create custom keyboard for existing java Android app and capture 3 types of measurements -- 2

Hello Freelancers! This project is for MAX $45-50AUD and includes the capture of 3 types of measurements and creation of custom keyboard to capture them. We want also to connect and store the measurements in our online db like it is done for the other types of measurements we are already doing via the app( etc gyroscope, accelerometer). And the integreation of this app with the other. It should be done on java Android. We have 3 days for this. The app should work on latest ANdroid 8 version! The things we want to be recorded in the custom keyboard in a new activity you will create are: 1. the time length a user is holding pressed a key from keyboard while writing 2. the time beetween 2 back to back presses on the keyboard 3. the x,y coorfinates of the finger when it presses a key So for this one the user should be able to write something on a text view or something. Kindly let me know if available so we can begin asap. I attach the apk. Happy Biding :)
