Android 获取 ArithmeticException：除以零，但我没有在任何地方除以零

基本上，我从用户存储中读取图像进行处理，在读取图像的同时，我计算inSampleSize以节省一些内存，以下是我的代码:

fun calculateInSampleSize(
    options: BitmapFactory.Options,
    reqWidth: Int,
    reqHeight: Int
): Int {
    // Raw height and width of image
    val (height: Int, width: Int) = options.run { outHeight to outWidth }
    var inSampleSize = 1
    if (height > reqHeight || width > reqWidth) {
        val halfHeight: Int = height / 2
        val halfWidth: Int = width / 2
        // Calculate the largest inSampleSize value that is a power of 2 and keeps both
        // height and width larger than the requested height and width.
        while (halfHeight / inSampleSize >= reqHeight && halfWidth / inSampleSize >= reqWidth) {
            inSampleSize *= 2
        }
    }
    return inSampleSize
}

但是，我得到的是ArithmeticException:While循环条件中被零除:

halfHeight / inSampleSize >= reqHeight && halfWidth / inSampleSize >= reqWidth个

我认为inSampleSize永远不会是零，因为它从1开始，并在每次迭代中乘以2.有人能帮帮我吗？这是怎么回事？

它只对一些用户崩溃(到目前为止有大约13次崩溃)，我不能重现它.

编辑，添加了故障日志(log):
