我有一个大json response. 我将它存储在一个字符串中。但是我在解析这个 json 时出现内存不足错误。
这里我是这样解析的
public ArrayList<String> parsing()
{
System.out.println("parsing start");
ArrayList<String> urls=new ArrayList<String>();
smusicname=null;smoviename=null;
sbookname=null;stelevisionname=null;
int position=0;
try {
JSONObject node1=new JSONObject(response);
JSONArray array1=node1.getJSONArray("data");
int length=array1.length();
for(int i=0;i<length;i++){
if(array1.getJSONObject(i).getString("id").equals(friendId.toString())){
position=i;
}
}
JSONObject node2 = array1.getJSONObject(position);
try{
if(node2.has("music")) {
JSONArray array2=node2.getJSONObject("music").getJSONArray("data");
JSONObject node4=array2.getJSONObject(0);
String name=node4.getString("name");
smusicname=name;
JSONObject node5=node4.getJSONObject("picture");
JSONObject node6=node5.getJSONObject("data");
String musicsurl=node6.getString("url");
urls.add(musicsurl); }
}
catch(JSONException e) {
e.printStackTrace();
}
try{
if(node2.has("movies")){
JSONArray array2=node2.getJSONObject("movies").getJSONArray("data");
JSONObject node4=array2.getJSONObject(0);
String name=node4.getString("name");
smoviename=name;
JSONObject node5=node4.getJSONObject("picture");
JSONObject node6=node5.getJSONObject("data");
String moviesurl=node6.getString("url");
urls.add(moviesurl);
}
}
catch(JSONException e){
e.printStackTrace();
}
try{
if(node2.has("books")) {
JSONArray array2=node2.getJSONObject("books").getJSONArray("data");
JSONObject node4=array2.getJSONObject(0);
String name=node4.getString("name");
sbookname=name;
JSONObject node5=node4.getJSONObject("picture");
JSONObject node6=node5.getJSONObject("data");
String bookurl=node6.getString("url");
urls.add(bookurl);
}
}
catch(JSONException e){
e.printStackTrace();
}
try{
if(node2.has("television")) {
JSONArray array2=node2.getJSONObject("television").getJSONArray("data");
JSONObject node4=array2.getJSONObject(0);
String name=node4.getString("name");
stelevisionname=name;
JSONObject node5=node4.getJSONObject("picture");
JSONObject node6=node5.getJSONObject("data");
String televisionsurl=node6.getString("url");
urls.add(televisionsurl);
}
}
catch(JSONException e) {
e.printStackTrace();
}
} catch (Exception e) {
Log.i("JSONException", e.getMessage());
}
return urls;
}`
在这里我出现内存不足错误
JSONObject node1=new JSONObject(response);
其中 response 是我存储 json 响应的字符串。
这是我的 logcat 消息
