Android在TextView中崩溃,indexoutboundsexception没有自定义代码的痕迹

我的Android应用程序在运行Android9的设备上的TextView中的某个地方崩溃。它发生在SpannableStringBuilder.checkRange中的参数验证期间。我的应用程序中有很多TextView对象,但还不清楚是哪一个导致了这个问题以及原因,因为堆栈跟踪中没有提供自定义代码。

这是一个非常罕见的崩溃,我无法复制它,所以使用调试器不是一个选项。播放存储报告此崩溃的以下设备、内部版本和版本:

Samsung Galaxy S10+ (beyond2q), Android 9

我已经反编译了SpannableStringBuilder.checkRange,在最后一个条件下,它的第1326行指向“throw”语句如下所示:

start < 0 || end < 0

SpannableStringBuilder#检查范围代码:

private void checkRange(final String operation, int start, int end) {
    if (end < start) {
        throw new IndexOutOfBoundsException(operation + " " +
                region(start, end) + " has end before start");
    }

    int len = length();

    if (start > len || end > len) {
        throw new IndexOutOfBoundsException(operation + " " +
                region(start, end) + " ends beyond length " + len);
    }

    if (start < 0 || end < 0) {
        throw new IndexOutOfBoundsException(operation + " " +
                region(start, end) + " starts before 0");
    }
}

有什么方法可以在自定义代码中识别出崩溃发生的位置吗?
有没有什么方法可以在应用程序级别修复它,或者这是一个需要系统修复的Android平台问题?
