Java 改造Android会错过服务器的一些响应（并非全部）

当我尝试在for循环中发送一些请求时，服务器的日志是正常的（所有请求都已接收，所有响应都已发送），但在androidstudio模拟器中，我只有一些响应，而不是所有响应。这是我的请求代码

 private void updateDatabase(JsonArray arrayJson) {
    final List<JsonObject> user_cars= new ArrayList<JsonObject>();
    for(JsonElement a : arrayJson){
        String carID = a.getAsString();
        carID=carID.substring(0,carID.length()-1);
        int index = carID.lastIndexOf('/');
        Integer id =Integer.parseInt(carID.substring(index+1));
        Log.e("Index",id.toString());
        AdaClient client = ServiceGenerator.createService(AdaClient.class);
        Call<JsonObject> call = client.retrieveCars(id);
        call.enqueue(new Callback<JsonObject>() {
            @Override
            public void onResponse(Call<JsonObject> call, retrofit2.Response<JsonObject> response) {
                Log.e("user_cars",response.body().toString());
                user_cars.add(response.body());
            }

            @Override
            public void onFailure(Call<JsonObject> call, Throwable t) {

            }
        });
    }

这里是logcat

如您所见，logcat中的一些响应缺少id=5，但完全是随机的。为什么?

尝试将response.body（）.string存储在字符串变量中并使用该字符串变量。为什么onFailure中没有Log.d？你怎么知道没有收到id为5的呼叫？只需从服务器和logcat读取日志，因为你可以看到logcat错过了id为5的汽车。我刚刚注意到，自启动此日志后，我仍然有E/BatteryStats服务：调制解调器信息无效：ModemActivityInfo{mTimestamp=0 msleptimems=0 midleItems=0 mtxtimes[]=[0,0,0,0,0,0]mRxTimeMs=0 mEnergyUsed=0}你理解JJF的问题吗？如果您得到一个错误（尽管服务器指示200），您只是忽略它。您应该记录错误，即使本例中不是这样。请尝试将response.body（）.string存储在字符串变量中，并使用该字符串变量。为什么onFailure中没有log.d？你怎么知道没有收到id为5的呼叫？只需从服务器和logcat读取日志，因为你可以看到logcat错过了id为5的汽车。我刚刚注意到，自启动此日志后，我仍然有E/BatteryStats服务：调制解调器信息无效：ModemActivityInfo{mTimestamp=0 msleptimems=0 midleItems=0 mtxtimes[]=[0,0,0,0,0,0]mRxTimeMs=0 mEnergyUsed=0}你理解JJF的问题吗？如果您得到一个错误（尽管服务器指示200），您只是忽略它。您应该记录错误，即使在本例中不是这样。
