I am developing android based educational device for students. I have customized android open source project. - changed launcher application - deleted standard system apps - added our apps.
Now i am struggling with changing functionalities of standard buttons like home, back and menu.
Please teach me how to customized standard buttons.
You need to customize several files in AOSP to implement functions you need. I have experienced with Android 6.0 so i will explain basing on this.
1.device/[company]/[type]/overlay/frameworks/base/packages/SystemUI/res/layout-sw600dp.xml Here you can add or delete standard buttons
2.frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarView.Java Here you can change functionalities of standard buttons.
I hope it will help you!
