options.setLaunchWindowingMode(WINDOWING_MODE_SPLIT_SCREEN_PRIMARY);
options.setSplitScreenCreateMode(SPLIT_SCREEN_CREATE_MODE_TOP_OR_LEFT);
//startActivityFromRecents split screen mode,if mHomeStack need to display secondary screen should not display recentsView.
mRootActivityContainer.getDefaultDisplay().getHomeStack().mForceHidden = true;
startActivityFromRecents(taskId, options.toBundle());
mRootActivityContainer.getDefaultDisplay().getHomeStack().mForceHidden = false;
}
mRootActivityContainer.getDefaultDisplay().getHomeStack().mForceHidden = true
报错后该值无法变为false导致。
2、#143082 【多任务】【电信版本】大屏横屏进入腾讯视频-点击视频旋转横屏观看，手势上滑进入多任务显示一半
在onPause流程时调用
private void updateLauncherLayoutOnPause() {
getMainThreadHandler().removeCallbacks(DelayUpdateLauncherLayout);
getMainThreadHandler().post(DelayUpdateLauncherLayout);
}
onresume时调用
public void updateLauncherLayout() {
getMainThreadHandler().removeCallbacks(DelayUpdateLauncherLayout);
getMainThreadHandler().postDelayed(DelayUpdateLauncherLayout,100);
}
onpause时使用handler post调用更新ui导致异常，改为直接调用或者不在onpause时更新ui（怀疑可能onpause-onstop流程继续执行，进入了onstop然后再更新的ui，这时不会执行更新，会遗留到下一次onstart或onresume执行，从而影响布局）
#150163 [CTS]大屏CtsDevicePolicyManagerTestCases:com.android.cts.devicepolicy.MixedProfileOwnerTest fail
1、开机启动时，SystemUI会去绑定桌面应用的TouchInteractionService服务，绑定成功后，SystemUI回调TouchInteractionService服务的onInitialize方法，onInitialize方法调用 preloadOverview(true /* fromInit /);去判断是否需要加载多任务界面；
preloadOverview(true / fromInit */)方法里面如果判断是非手势导航就不加载（即虚拟导航），手势导航的话就会调用startRecentsActivity去启动多任务界面；这段代码应该是原生的逻辑，理论上pixel应该也会有问题
