Question

我正在尝试使用Edwardvanraak库将条形码扫描仪添加到我的应用中，但是我收到了错误。

这是我的错误日志：

{
'UUID(id1)': ({'due': 'datetime.date(2018, 3, 10)', 'status': 'Done'}, 
               {'new_val': 'Pass', 'amount': 123.0}), 
'UUID(id2)': ({'due_date': 'datetime.date(2018, 3, 10)', 'old_status': 'Done'}, 
              {'new_val': 'Fail', 'amount': 0})
}

以下是我的QR码扫描代码。我尝试在新项目中添加相同的代码，它工作正常。但是我无法解决主项目中的错误：

请添加Google Mobile视觉依赖项，它将正常工作。

implementation 'com.google.android.gms:play-services-vision:15.0.2'
