在 11 MB 的 android 中解析大型 json

我在使用 GSON 和 Jackson 在 android 中解析大约 11MB 的大型 JSON 时遇到问题。问题是发生内存不足错误异常并且堆大小不足以完成此过程。这是我的纸模型课

public class Paper {
    public int primaryKey;
    public String title;
    public int entry;
    public Boolean favourite;
    public String comment;
    public int opt;
    public int score;
}

这是我的响应模型类

public class Response {
    public List<Paper> papers;
}

这是我的 JSON 字符串

{"Paper":[[{"abstract":"Not Available","title":"A Fully Intraocular 0.0169mm<sup>2<\/sup>/pixel 512-Channel Self-Calibrating Epiretinal Prosthesis in 65nm CMOS","primaryKey":3,"entry":9,"score":-1,"comment":null,"favourite":false,"opt":1},{"abstract":"Not Available","title":"A Scalable 2.9mW 1Mb/s eTextiles Body Area Network Transceiver with Remotely Powered Sensors and Bi-Directional Data Communication","primaryKey":14,"entry":9,"score":-1,"comment":null,"favourite":false,"opt":1},{"abstract":"Not Available","title":"A 0.18µm CMOS SoC for a 100m-Range 10fps 200×96-Pixel Time-of-Flight Depth Sensor","primaryKey":20,"entry":9,"score":-1,"comment":null,"favourite":false,"opt":1},{"abstract":"Not Available","title":"A 12b 1.6GS/s 40mW DAC in 40nm CMOS with >70dB SFDR over Entire Nyquist Bandwidth","primaryKey":26,"entry":9,"score":-1,"comment":null,"favourite":false,"opt":1},{"abstract":"Not Available","title":"All-Digital Hybrid Temperature Sensor Network for Dense Thermal Monitoring","primaryKey":49,"entry":9,"score":-1,"comment":null,"favourite":false,"opt":1},{"abstract":"Not Available","title":"32Gb/s Data-Interpolator Receiver with 2-Tap DFE in 28nm CMOS","primaryKey":51,"entry":9,"score":-1,"comment":null,"favourite":false,"opt":1},{"abstract":"Not Available","title":"A 93% Efficiency Reconfigurable Switched-Capacitor DC-DC Converter Using On-Chip Ferroelectric Capacitors","primaryKey":60,"entry":9,"score":-1,"comment":null,"favourite":false,"opt":1},{"abstract":"Not Available","title":"A 45nm CMOS Near-Field Communication Radio with 0.15A/m RX Sensitivity and 4mA Current Consumption in Card Emulation Mode","primaryKey":61,"entry":9,"score":-1,"comment":null,"favourite":false,"opt":1}]]}

我不知道我在哪里做错了。我因为论文而变得无效。

我在使用 GSON 和 Jackson 在 android 中解析大约 11MB 的大型 JSON 时遇到问题。

下载和解析它会非常困难。11MB 太高了。

您可以使用的替代方案是：

您可以修改您的 Web 服务，使其具有类似 Counter 的分区， counter=1,2,3....使 WS 以这样的方式创建一个 WS，即解析后的前 1000 条记录用于 counter=1，另一个数据将用于 counter=2并解析它等等..

这将帮助您以某种方式解决您的问题。
