* Move WindowContext module to window packageCharles Chen2021-03-241-159/+0
| | | | | | | | | | | In this way, we can clarify the owners and it is easier to maintain. Also refactor to move WindowContext creation logic to ContextImpl.

* Enable to listen to WindowContext's config changesCharles Chen2021-03-191-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | This CL overrides registerComponentCallbacks for WindowContext. Users can use below code snippet to listen to Configuration changes. ``` Context windowContext = context.createWindowContext( display, ...); windowContext.registerComponentCallbacks( new ComponentCallbacks() { @Override public void onConfigurationChanged( Configuration newConfig) { // Do Something } }); ``` Bug: 181134729 Test: atest WindowContextTests Test: atest ComponentCallbacksControllerTest Change-Id: Iff46607bae3c942a96b64dcc97708f3a8c33f23a
* Migrate WindowContext to WindowContextListener mechanismCharles Chen2021-02-041-22/+10
| | | | | | | | | | | | | | | | | | | | | 1. Use registerWindowContextListener instead of addWindowTokenWithOptions 2. Clean up the logic of sending the config to the client in WindowToken 3. Add a mechanism in WMS#addWindow, when a WindowContext adds a view, the server side will switch to register the WindowToken for the WindowContext. In this way, we won't add a WindowToken until adding the fist view. Also, we could apply an existing window token by overriding WindowManager.LayoutParams.token.

* Limit number of window context without any windowCharles Chen2020-04-221-0/+6
| | | | | | | | | | | | | | | | | | | | | | | This change is to prevent misuse of window context from app and leads to performance drop on system by limit the numer of window context an app can use. Code snippet below is a sample to cause this issue: ``` Rect getBounds() { Context windowContext = context.createWindowContext(...); return windowContext.getSystemService(WindowManager.class) .getCuttentWindowMetrics().getBounds() } ``` This method could be invoked dozens of times and produce dozens of window tokens. It would slow down the speed of window traversalling. These token won't be removed until system server has been GC'd.

* Fix WindowContext leakCharles Chen2020-04-081-3/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The root causes of this issue are: 1. WindowTokenClient#attachContext makes WindowTokenClient has strong reference to WindowContext, which leads to WindowContext cannot be GC'd. 2. WMS#removeWindowToken needs MANAGE_APP_TOKEN permission which normal apps don't hold. This CL does following things: 1. Use weak reference instead on WindowTokenClient#mContext. 2. Relax WMS#removeWindowToken to check callingUid if MANAGE_WINDOW_TOKEN permission is not held 3. Deliver config changes to the client side in WMS#addWindowTokenWithOption 4.

* Generate WindowInsets with new insets APICharles Chen2020-03-051-1/+0
| | | | | | | | | | | | | In previous CL[1], WindowMetrics#WindowInsets is provided with legacy insets, which are stable insets and system window insets. With the new insets mode enabled, we should provide insets with new insets API.

When config change callback is received, it will update the resources associated with the window token.
