This could be avoided using automated test * that checks all possible inputs and asserts that the final state is valid. * See sample test for the default transitions in {@link BookStyleClosedStateCalculatorTest}. * * - Tent mode is defined as a posture when the device is partially opened and placed on the ground * on the edges that are parallel to the hinge. * - Wedge mode is when the device is partially opened and placed flat on the ground with the part * of the device that doesn't have the display * - Reverse wedge mode is when the device is partially opened and placed flat on the ground with * the outer screen down, so the outer screen is not accessible * * Behavior description: * - When unfolding with screens off we assume that no sensor data available except hinge angle * (based on hall sensor), so we switch to the inner screen immediately * * - When unfolding when screen is 'on' we can check if we are likely in tent or wedge mode * - If not likely tent/wedge mode or sensors data not available, then we unfold immediately * After unfolding, the state of the inner screen 'on' is sticky between 0 and 45 degrees, so * it won't jump back to the outer screen even if you move the phone into tent/wedge mode. The * stickiness is reset after fully closing the device or unfolding past 45 degrees. * - If likely tent or wedge mode, switch only at 90 degrees * Tent/wedge mode is 'sticky' between 0 and 90 degrees, so it won't reset until you either * fully close the device or unfold past 90 degrees. * * - When folding we can check if we are likely in reverse wedge mode * - If not likely in reverse wedge mode or sensor data is not available we switch to the outer * screen at 45 degrees and enable sticky tent/wedge mode as before, this allows to enter * tent/wedge mode even if you are not on an even surface or holding phone in landscape * - If likely in reverse wedge mode, switch to the outer screen only at 0 degrees to allow * some use cases like using camera in this posture, the check happens after passing 45 degrees * and inner screen becomes sticky turned 'on' until fully closing or unfolding past 45 degrees */ public class BookStyleStateTransitions { public static final List DEFAULT_STATE_TRANSITIONS = new ArrayList<>();
