java - Weka模型在android中读取错误

Question

我在机器上创建了我的 weka 模型并将其导入到 android 项目中。当我尝试创建分类器时，当我尝试反序列化我创建的模型时，它会给出错误“exception.java.io.StreamCorruptedException”。该代码在机器上完美运行。

这是我的代码，

InputStream fis = null;

        fis = new InputStream("/modle.model");

        InputStream is = fis;

        Classifier cls = null;

       //here im getting the error when trying to read the Classifier
            cls = (Classifier) SerializationHelper.read(is);

        FileInputStream datais = null;

            datais = new FileInputStream("/storage/emulated/0/window.arff");


        InputStream dataIns = datais;
        DataSource source = new DataSource(dataIns);
        Instances data = null;
        try {
            data = source.getDataSet();
        } catch (Exception e) {
            e.printStackTrace();
        }
        data.setClassIndex(data.numAttributes() - 1);

        Instance in = new Instance(13);
        in.setDataset(data);
        in.setValue(0, testWekaModle1[0]);
        in.setValue(1, testWekaModle1[1]);
        in.setValue(2, testWekaModle1[2]);
        in.setValue(3, testWekaModle1[3]);
        in.setValue(4, testWekaModle1[4]);
        in.setValue(5, testWekaModle1[5]);
        in.setValue(6, testWekaModle1[6]);
        in.setValue(7, testWekaModle1[7]);
        in.setValue(8, testWekaModle1[8]);
        in.setValue(9, testWekaModle1[9]);
        in.setValue(10, testWekaModle1[10]);
        in.setValue(11, testWekaModle1[11]);

        double value = 0;

            value = cls.classifyInstance(in);

        in.setClassValue(value);

这是完整的堆栈跟踪，

请帮我解决这个问题。

这已解决，该模型是在不同的环境(PC)中创建的，并尝试在 android 环境中反序列化，但由于两种类型的 JDK 完全不同，因此出现错误。
