I have installed Android (I think version 4.4) in an Orange Pi 2g-IoT board, using their officially supplied android image. In the user interface some buttons are clickable and some are not clickable. I have tried pressing on the buttons from the GUI as well as by sending tap events from adb. The problem is same whether I use the physical screen or adb. For example, when I connect this device as I get the following screen
Here I can tap and select/unselect check boxes, but I cannot press and drag. I managed to go to home screen through adb, but then I get this UI
This button is untappable. I cannot press on it even if I send press event at it's co-ordinates using adb. Some other examples are given below:
The android image provided or this board seems to be based on stock android and has root. The LCD hardware itself can clearly receive touch events. The board's website does not mention any kind of screen calibration that we need to do either. Then what is the difference between the various clickable UI components shown above, from the point of view of the OS? IS it possible to select a particular button on whatever UI is on the screen using adb (instead of sending tap events at a specified coordinate), like using tab key to select a button on Windows?
