Android-O在辅助显示屏上启动 [英] Android-O launch on secondary display

问题描述

当我尝试启动活动意图时，Android-O中新的ActivityOptions setLaunchDisplayId(int launchDisplayId)函数似乎总是使我的应用程序崩溃.

The new ActivityOptions setLaunchDisplayId (int launchDisplayId) function in Android-O seems to always crash my app when I try to launch an activity intent.

当我从自己的应用程序启动活动以及尝试启动其他应用程序(例如Chrome Canary)时都如此.

Both when I launch activities from my own app and when I try to launch other apps i.e. Chrome Canary.

有人知道这是新API的普遍问题还是我遗漏了一些东西?

Does anyone know if this is a general problem with the new API's or am I missing something:

下面是我的代码的一小段:

A small snippet of my code is below:

options.setLaunchDisplayId(1);startActivity(intent，options);

注意我正在测试是否启用模拟第二个屏幕"(如果有问题，请使用@ 1080p).

NOTE I was testing with 'simulate a second screen' enabled (@1080p if it matters).

更新我已经尝试过ADB命令 adb shell start com.chrome.canary --display 1 ，然后我得到消息:

UPDATE I have tried the ADB command adb shell start com.chrome.canary --display 1, and I get the message:

开始:必须是root

start: must be root

推荐答案

我已通过带有以下代码的新API连接到第二个屏幕，但到目前为止尚未与之交互.

I have connected to the second screen via the new API's with the code below, but as of yet have no way of interacting with it.

 Bundle bdl;
 MediaRouter mediaRouter = (MediaRouter) mContext.getSystemService(Context.MEDIA_ROUTER_SERVICE);
 MediaRouter.RouteInfo route = mediaRouter.getSelectedRoute(MediaRouter.ROUTE_TYPE_LIVE_VIDEO);
 if (route != null) {
     Display presentationDisplay = route.getPresentationDisplay();
     bdl = ActivityOptions.makeClipRevealAnimation(mView, left, top, width, height).setLaunchBounds(rect).setLaunchDisplayId(presentationDisplay.getDisplayId()).toBundle();
     Bundle optsBundle = true ? bdl : null;
     Intent intent = new Intent(mContext, SecondaryActivity.class);
     intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
     mContext.startActivity(intent, optsBundle);
 }
