示例代码:
onLaunch: ()=> {  
            console.log('App Launch')  

            var ll = wx.getSystemInfo();  
            console.log(ll)  
            var lk = uni.getSystemInfo({  
                complete: (res)=> {  
                    console.log(res)  
                }  
            })  
            var lj = uni.getSystemInfoSync()  
            console.log(lj)  

            setTimeout(function(){  
                var ll = wx.getSystemInfo();  
                console.log(ll)  
                var lk = uni.getSystemInfo({  
                    complete: (res)=> {  
                        console.log(res)  
                    }  
                })  
                var lj = uni.getSystemInfoSync()  
                console.log(lj)  
            },1000)  
},

操作步骤:

uni.getSystemInfoSync(),第一次安装 或者 热启动 得到的打印是异常的值

预期结果:

{
"errMsg": "getSystemInfo:ok",
"brand": "Xiaomi",
"model": "MI 8",
"pixelRatio": 2.75,
"screenWidth": 393,
"screenHeight": 817,

"height": 735
},
"safeAreaInsets": {
"top": 32,
"right": 0,
"bottom": 0,
"left": 0
}
}

实际结果:

{
"errMsg": "getSystemInfo:ok",
"brand": "Xiaomi",
"model": "MI 8",
"pixelRatio": 2.880000114440918,
"screenWidth": 375,

"statusBarHeight": 32,

}
}

bug描述:

在APP.vue onLaunch 或者其他 xx.vue 里面调这个方法
var ll = wx.getSystemInfo();
console.log(ll)
var lk = uni.getSystemInfo({
complete: (res)=> {
console.log(res)
}
})
var lj = uni.getSystemInfoSync()
console.log(lj)

第一次安装 或者 热启动 得到的打印是(该打印是异常的值):
{
"errMsg": "getSystemInfo:ok",
"brand": "Xiaomi",
"model": "MI 8",
"pixelRatio": 2.880000114440918,
"screenWidth": 375,
"screenHeight": 781,
"windowWidth": 375,
"windowHeight": 731,
"statusBarHeight": 32,
"language": "zh-CN",
"system": "10",
"version": "1.9.9.80255",
"fontSizeSetting": "",
"platform": "android",
"SDKVersion": "",
"windowTop": 0,
"windowBottom": 0,
"safeArea": {
"left": 0,
"right": 375,
"top": 32,
"bottom": 731,
"width": 375,
"height": 699
},
"safeAreaInsets": {
"top": 32,
"right": 0,
"bottom": 0,
"left": 0
}
}

不是第一次安装且是冷启动打印是(该打印是正常的值):
{
"errMsg": "getSystemInfo:ok",
"brand": "Xiaomi",
"model": "MI 8",
"pixelRatio": 2.75,
"screenWidth": 393,
"screenHeight": 817,
"windowWidth": 393,
"windowHeight": 767,
"statusBarHeight": 32,
"language": "zh-CN",
"system": "10",
"version": "1.9.9.80255",
"fontSizeSetting": "",
"platform": "android",
"SDKVersion": "",
"windowTop": 0,
"windowBottom": 0,
"safeArea": {
"left": 0,
"right": 393,
"top": 32,
"bottom": 767,
"width": 393,
"height": 735
},
"safeAreaInsets": {
"top": 32,
"right": 0,
"bottom": 0,
"left": 0
}
}

异常值就会导致APP底部白屏,视频video跑偏
