【报Bug】setScreenBrightness出现闪退，getScreenBrightness获取值大于1

分类：HTML5+

bug已修复

产品分类： HTML5+

HBuilderX版本号： 2.8.13

手机系统： Android

手机系统版本号： Android 10

手机厂商：小米

手机机型： Redmi K20 Pro

打包方式：云端

示例代码：


uni.getScreenBrightness({  
  success: function(res) {  
  bright=parseFloat(res.value);  
console.log(bright)  
 }  
});  

uni.setScreenBrightness({  
value: bright,  
success: function(res) {  
console.log('设置屏幕亮度成功');  
}  
});

操作步骤：


uni.getScreenBrightness({  
  success: function(res) {  
  bright=parseFloat(res.value);  
console.log(bright)  
 }  
});  

uni.setScreenBrightness({  
value: 0.5,  
success: function(res) {  
console.log('设置屏幕亮度成功');  
}  
});

预期结果：

bright应该小于1
亮度设置成功

实际结果：

bright应该大于1
app闪退

bug描述：

使用uni.getScreenBrightness(）获取的值大于1

使用uni.setScreenBrightness()设置亮度时出现
App Hide
App Show

1 getScreenBrightness获取值大于1 。问题已确认。小米手机 rom，数据异常。已处理。稍后版本更新。
2 设置亮度崩溃。提供一下崩溃日志和系统版本。以及复现代码

hbuilder x 2.9.5 小米系列手机获取亮度异常的问题已修复

该问题目前已经被锁定, 无法添加新回复

【报Bug】setScreenBrightness出现闪退，getScreenBrightness获取值大于1

示例代码：

`uni.getScreenBrightness({ success: function(res) { bright=parseFloat(res.value); console.log(bright) } }); uni.setScreenBrightness({ value: bright, success: function(res) { console.log('设置屏幕亮度成功'); } });`

操作步骤：

`uni.getScreenBrightness({ success: function(res) { bright=parseFloat(res.value); console.log(bright) } }); uni.setScreenBrightness({ value: 0.5, success: function(res) { console.log('设置屏幕亮度成功'); } });`

预期结果：

bright应该小于1
亮度设置成功

实际结果：

bright应该大于1
app闪退
