Question

我使用Retrofit2检索3个数据：id，日期，链接（链接包含另一个json文件）。 <-JSON文件具有3000个条目。每次获取数据：ID，DATE，LINK时，我都会发送另一个请求以从链接获取数据。问题是，我总共有450 000个链接，所以我的应用程序每次都崩溃。

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(API_DATA.BASE_URL)
            .addConverterFactory(GsonConverterFactory.create()) 
            .build();

    API_DATA api = retrofit.create(API_DATA.class);
    Call<List<DATA>> call = api.getDATA();
    call.enqueue(new Callback<List<DATA>>() {
        @Override
        public void onResponse(Call<List<DATA>> call, Response<List<DATA>> response) {
            List<DATA> dataList = response.body();
            String[] data= new String[dataList.size()];
            for (int i = 0; i < 3000; i++) {
                data[i] = dataList.get(i).getId();
                Log.d(TAG, 
                        "id: " + dataList.get(i).getId() + "\n" +
                        "date: " + dataList.get(i).getDate() + "\n" +
                        "links: " + dataList.get(i).getLinks() + "\n");
            }

        }

        @Override
        public void onFailure(Call<List<DATA>> call, Throwable t) {
            //Toast.makeText(getApplicationContext(), t.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });

我想阅读每个条目并在每次获得新链接时发送请求。

这是我的StackStrace：

在清单文件中添加以下行：android：largeHeap =“ true”。我认为它将解决您的内存不足错误。
