我正在尝试使用ProGuard和我可能找到的所有可能规则来混淆我的应用程序，但仍然出现以下错误

我关注了Stack Overflow上的大量帖子，并添加了他们的所有修复程序，并在信中遵循了他们的示例，但似乎没有一个可以解决我的问题。
之后这是运行时产生问题的代码
private String getCellValue(FormulaEvaluator evaluator, Cell cell){
String cellString = "";
try {
CellValue cellValue = evaluator.evaluate(cell);
if(cellValue != null){
switch (cellValue.getCellType()) {
case Cell.CELL_TYPE_BOOLEAN:
cellString = Boolean.toString(cellValue.getBooleanValue());
break;
case Cell.CELL_TYPE_NUMERIC:
cellString = Double.toString(cellValue.getNumberValue());
break;
case Cell.CELL_TYPE_STRING:
cellString = cellValue.getStringValue();
break;
}
}
} catch (Exception e) {
Log.e(TAG, e.getMessage());
}
return cellString;
}

如果有帮助，这是在POI OperationEvaluatorFactory.class中引发异常的代码部分
private static void put(Map<OperationPtg, Function> m, OperationPtg ptgKey, Function instance) {
Constructor<?>[] cc = ptgKey.getClass().getDeclaredConstructors();
if (cc.length <= 1 && Modifier.isPrivate(cc[0].getModifiers())) {
m.put(ptgKey, instance);
} else {
throw new RuntimeException("Failed to verify instance (" + ptgKey.getClass().getName() + ") is a singleton.");
}
}
我在运行时遇到这些错误，并且这些错误仅出现在发行版中，因此可以肯定地认为ProGuard是我的问题。
