当我尝试从服务器获取json格式的字符串时，我得到如下错误 java.lang.OutOfMemoryError：无法分配带有16777216个空闲字节的68706640字节分配和37MB直到OOM 在java.util.ArrayList.add（ArrayList.java:118）
我的java代码如下
JSONArray eventArray = eventResult.getJSONArray("event");
for (int i=0; i<eventArray.length(); i++){
final ArrayList<String> divisi = new ArrayList<>();
final ArrayList<Timeline> timelines = new ArrayList<>();
JSONObject eventObj = eventArray.getJSONObject(i);
String namaEvent = eventObj.getString("nama_event");
String deskripsi = eventObj.getString("deskripsi");
String tanggal = eventObj.getString("tanggal");
JSONArray eventArray1 = eventObj.getJSONArray("divisi");
JSONArray eventArray2 = eventObj.getJSONArray("timeline");
for (int j=0; j<eventArray1.length(); i++){
JSONObject eventObj1 = eventArray1.getJSONObject(j);
String namaDivisi = eventObj1.getString("nama_divisi");
divisi.add(namaDivisi);
}
for (int k=0; k<eventArray2.length(); k++){
JSONObject eventObj2 = eventArray2.getJSONObject(k);
String tanggalTimeline = eventObj2.getString("tanggal_timeline");
String deskripsiTimeline = eventObj2.getString("deskripsi_timeline");
Timeline timeline = new Timeline(tanggalTimeline, deskripsiTimeline);
timelines.add(timeline);
}
Event event = new Event(namaEvent,deskripsi,tanggal,divisi,timelines);
events.add(event);
}
我要解析的json结构是

任何人都可以提供帮助吗？
答案 0 :(得分：3)
我认为这可能是这个错字？
for (int j=0; j<eventArray1.length(); i++){
JSONObject eventObj1 = eventArray1.getJSONObject(j);
String namaDivisi = eventObj1.getString("nama_divisi");
divisi.add(namaDivisi);
}
你正在增加i而不是j。
尝试在此处更改代码：
for (int j=0; j<eventArray1.length(); j++)
