Question

我无法理解这里的问题：是图书馆的问题吗？

java.lang.IllegalArgumentException：表单编码的方法必须包含至少一个@Field。用于方法ApiInterface.hitCheckVersionApi $ 79c79d47 在retrofit2.ServiceMethod $ Builder.methodError（ServiceMethod.java:720）在retrofit2.ServiceMethod $ Builder.build（ServiceMethod.java:11711）在retrofit2.Retrofit.loadServiceMethod（Retrofit.java:166）在retrofit2.Retrofit $ 1.invoke（Retrofit.java:145）在java.lang.reflect.Proxy.invoke（Proxy.java:1006） at $ Proxy3.hitCheckVersionApi $ 79c79d47（来源不明）在com.shopoholicbuddy.activities.SplashActivity.onCreate（SplashActivity.java:1058）

以下是代码示例：

  @FormUrlEncoded
    @POST("checkversion")
    Call<ResponseBody> hitCheckVersionApi(@FieldMap HashMap<String, String> map);

实施代码为：

 private void checkForceUpdateAPI() {
        if (AppUtils.getInstance().isInternetAvailable(this)) {
            final HashMap<String, String> params = new HashMap<>();
            params.put(Constants.NetworkConstant.PARAM_VERSION_NAME, getAppVersion(this));
            params.put(Constants.NetworkConstant.PARAM_PLATFORM, "1");
            params.put(Constants.NetworkConstant.PARAM_APP_TYPE, "2");
            ApiInterface apiInterface = RestApi.createService(this, ApiInterface.class);
            Call<ResponseBody> call = apiInterface.hitCheckVersionApi(params);
            ApiCall.getInstance().hitService(this, call, new NetworkListener() {
                @Override
                public void onSuccess(int responseCode, String response, int requestCode) {
                    try {
                        VersionUpdateResponse bean = new Gson().fromJson(response, VersionUpdateResponse.class);
                        if (bean.getCode() == 310) {
                            if (bean.getResult().getVersionName() != null && Double.parseDouble(bean.getResult().getVersionName())<=(Double.parseDouble(getAppVersion(SplashActivity.this)))) {
                                showSplashScreen();
                            } else {
                                AlertDialog.Builder builder = new AlertDialog.Builder(SplashActivity.this, R.style.DatePickerTheme);
                                builder.setTitle(getString(R.string.new_version_available));
                                builder.setMessage(getString(R.string.upgrade_to_new_version));
                                builder.setPositiveButton(getString(R.string.update), (dialogInterface, i) -> redirectStore("https://play.google.com/store/apps/details?id=com.shopoholic"));
                                if (bean.getResult().getUpdateType() != null && bean.getResult().getUpdateType().equals("1")) {
                                    builder.setNegativeButton(getString(R.string.no_thanks), (dialogInterface, i) -> showSplashScreen());
                                }
                                builder.setCancelable(false);
                                builder.show();
                            }
                        } else {
                            showSplashScreen();
                        }
                    } catch (Exception e) {
                        e.printStackTrace();
                        showSplashScreen();
                    }

                }

我在发布版本中遇到了同样的问题。添加保护规则将解决该问题。 https://github.com/square/retrofit/blob/master/retrofit/src/main/resources/META-INF/proguard/retrofit2.pro 如果您在DEBUG构建中遇到此错误，则您的代码有问题。
