10. • If not already, upload your app to the Play Store • Approve your apps for your organization • Upload configuration txt file • Optimize for this new environment! What do you need to do?
11. • Target API Level 23 or higher • Make sure what you’re only requiring what is actually needed in your manifest • New 1st class input methods ◦ Keyboard ◦ Mouse/Trackpad ◦ Stylus • Multi window environments and larger screens ◦ More on this later! Optimize?
12. yourView.setOnContextClickListener { //context-click action } Mouse/Trackpad Right click support
13. yourView.setOnHoverListener{ _, motionEvent -> when (motionEvent.actionMasked) { MotionEvent.ACTION_HOVER_ENTER -> { //UI Change } MotionEvent.ACTION_HOVER_EXIT -> { //revert } ... } } Mouse/Trackpad Right click support Hover actions
14. yourView.setOnGenericMotionListener { view, event -> if (event.actionMasked == MotionEvent.ACTION_SCROLL) { //scroll action } ... } Mouse/Trackpad Right click support Hover actions Scroll events
15. yourView.setOnGenericMotionListener { view, event -> if (event.actionMasked == MotionEvent.ACTION_SCROLL && KeyEvent.metaStateHasModifiers( event.metaState,KeyEvent.META_CTRL_ON)) { //ctrl + scroll action } ... } Mouse/Trackpad Right click support Hover actions Scroll events
16. yourView.setOnGenericMotionListener { view, event -> if (event.actionMasked == MotionEvent.ACTION_SCROLL && KeyEvent.metaStateHasModifiers( event.metaState,KeyEvent.META_CTRL_ON)) { //ctrl + scroll action } ... } Mouse/Trackpad Right click support Hover actions Scroll events
17. yourView.nextFocusDownId = //… yourView.nextFocusUpId = //… yourView.nextFocusLeftId = //… yourView.nextFocusRightId = //… yourView.nextFocusForwardId = //… Keyboard Navigation
18. yourView.setOnKeyListener { _, _, keyEvent -> if (keyEvent.keyCode == KeyEvent.KEYCODE_ENTER) { //submit form } … } Keyboard Navigation Actions on key-press
19. <item android:alphabeticShortcut="string" android:alphabeticModifiers=["META" | "CTRL" | "ALT" | "SHIFT"| "SYM" |"FUNCTION" Keyboard Navigation Actions on key-press Shortcuts
20. override fun dispatchKeyShortcutEvent( event: KeyEvent): Boolean { if (event.keyCode == KeyEvent.KEYCODE_Z && event.hasModifiers(KeyEvent.META_CTRL_ON)) // undo action return true } return super.dispatchKeyShortcutEvent(event) } Keyboard Navigation Actions on key-press Shortcuts
21. • Layouts for larger screens Window Management
22. Window Management
23. • Layouts for larger screens • Handling both orientations Window Management
24. Window Management
25. • Layouts for larger screens • Handling both orientations • Free form window resizing Window Management
26. • Layouts for larger screens • Handling both orientations • Free form window resizing • Use window size not screen size! Window Management
27. • Layouts for larger screens • Handling both orientations • Free form window resizing • Use window size not screen size! • Drag and drop Window Management
28. • What happens? ◦ Configuration change occurs when crossing layout/view boundaries ◦ onDraw() called constantly • Just like orientation changes, but more frequent • Save and restore state process must be fast • Architecture components help make this easier! What is Free-form Resizing?
29. Resizing Codelab
30. • Chrome OS Emulator ◦ Preview • ADB over USB ◦ Pixelbook & HP Chromebook X2 ◦ More information on it’s way • Android Studio on Chrome OS ◦ Preview only for Pixelbooks currently Developer Tools
31. • Requires none or little code changes to run on Chrome OS • Restrictions are handled through the Cloud DPC and admin site, but on the device is no different. • Reusability of already developed applications • Optimize and allow your users to be more productive and take advantage of these new platforms!
