在模拟器上运行程序报错

创建好了模拟器,运行一个程序时,选择模拟器设备

没有看到报错,看到studio下方显示install apk,查看模拟器launcher,发现apk已经安装上

直接点击模拟器上的图标,没有成功启动,发现是模拟器 launcher一直在crash,但是之前安装的一个应用可以正常运行

使用的Android Studio版本为3.1.1,该问题只在Android P emulator上出现,使用API26的模拟器就是好的.
跟http://www.hackerav.com/?post=67797 这里的问题一样.
先mark一下,还不知道原因…推测应该是该模拟器有问题,因为待机情况下也会出现launcher crash,systemUI crash
