Android较低版本的设备(4.1 - 4.4)给出了SSL错误.以前版本适用于以下版本:

implementation 'com.squareup.okhttp3:okhttp:3.9.1'
implementation 'com.squareup.okhttp3:okhttp-urlconnection:3.9.1'
implementation 'com.squareup.okhttp3:logging-interceptor:3.9.1'

implementation 'com.squareup.retrofit2:retrofit:2.3.0'
implementation 'com.squareup.retrofit2:converter-jackson:2.3.0'
implementation 'com.squareup.retrofit2:adapter-rxjava:2.3.0'

但升级这些库后,事情就会发生变化 每个服务调用都会提供SSL握手异常.

implementation 'com.squareup.okhttp3:okhttp:3.10.0'
implementation 'com.squareup.okhttp3:okhttp-urlconnection:3.10.0'
implementation 'com.squareup.okhttp3:logging-interceptor:3.10.0'

implementation 'com.squareup.retrofit2:retrofit:2.4.0'
implementation 'com.squareup.retrofit2:converter-jackson:2.4.0'
implementation 'com.squareup.retrofit2:adapter-rxjava:2.4.0'

此外,如果我将这些库降级到以前的版本,它仍然无法正常工作.但git checkout到上一次提交工作正常.懵懵懂懂.

以下是我使用的代码:

public class PaymentAndReceiptAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    private static final int TYPE_HEADER = 0;
    private static final int TYPE_ITEM = 1;

    public Context context;
    private List<CustomerAndAmount> customerAndAmountList = new ArrayList<>();
    private PaymentAndReceiptItemClickListener paymentAndReceiptItemClickListener;
    private Map<Long, Double> chartMap;

    public PaymentAndReceiptAdapter(final Context context, final List<CustomerAndAmount> customerAndAmountList, final Map<Long, Double> chartMap, final PaymentAndReceiptItemClickListener paymentAndReceiptItemClickListener) {
        this.context = context;
        setResult(customerAndAmountList, chartMap);
        this.paymentAndReceiptItemClickListener = paymentAndReceiptItemClickListener;
    }

    public void setResult(final List<CustomerAndAmount> customerAndAmountList, final Map<Long, Double> chartMap) {
        this.customerAndAmountList.clear();
        if (null != customerAndAmountList) {
            this.customerAndAmountList.addAll(customerAndAmountList);
        }
        this.chartMap …

final RealmObjectSchema customerSchema = schema.get("Customer");
customerSchema.removeField("creditPeriod")
    .addField("creditPeriod", Long.class);

以上是我用于领域迁移的代码.我删除了以前字符串已经存在的字段,然后在迁移代码和Pojo.class中添加了相同的字段更改其数据类型

从必需变量到可空值的领域迁移

我在以前的领域版本中有一个变量，它是必填字段。但是对于较新的版本，我希望它不是必需的，而是可以为空的版本。如何通过领域迁移做到这一点？
