很抱歉包含了这么长的代码。我试图从youtube上的教程中学习,但视频教程缺少解释。教程视频使用java,但我尝试为我的kotlin应用程序实现它。但当我尝试拍照时,我会出现以下错误:

Error reading Sqlite database: Database 'LiveSqliteDatabaseId(path=/data/data/com.example.b1/databases/google_app_measurement_local.db,name=google_app_measurement_local.db, connectionId=1) not found

为什么我会犯这个错误?我的代码有什么问题?
我还制作了textview,可以点击它来选择类别,但它不起作用。代码中的categorydialog()函数似乎有问题。这就是导致上述错误的原因吗?
我的代码:

class AddProductActivity : AppCompatActivity() {
    private val CAMERA_REQUEST_CODE:Int =200

    private val IMAGE_PICK_GALLERY_CODE:Int =400
