排球 - parseNetworkResponse OutOfMemoryError
Volley - parseNetworkResponse OutOfMemoryError
我正在使用 Volley 来管理我的应用程序。有时，当响应过大时，我会在没有太多 RAM 的设备上遇到 OOM。我不确定如何解决这个问题。我知道 Volley 将它的响应存储在内存中，但是我的应用程序非常依赖 Volley，以至于切换起来会很痛苦。我在使用 Retrofit 时也遇到了问题。我试过使用 JsonReader，但它似乎仍然会发生。我有一个与 Volley 一起使用的自定义请求。它 returns 一个 Gson JsonObject。这是我目前的代码，当响应数据长度返回 5511532 (5mb) 时，应用程序收到 OOM。
@Override
protected Response<T> parseNetworkResponse(NetworkResponse response) {
try {
String json = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
if (LOG_HEADERS) {
Log.d("GsonResponseHeaders", response.headers.toString());
}
if (LOG_JSON) {
Log.d("GsonRequestResponse", json);
}
return Response.success(gson.fromJson(json, clazz), HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JsonSyntaxException e) {
return Response.error(new ParseError(e));
} catch (OutOfMemoryError e) {
Log.d("ResponseLength", "-- " + response.data.length);
return Response.error(new ParseError(e));
}
}

这是抛出 OOM 的示例响应。

大家好，我试着分开回答。它似乎有所帮助，但在 3-4 个请求之后它仍然给我一个 OOM。我相信这与排球有关。这是我对每个响应的 GC，它每次都在增长。请注意，堆每次都会增长。我在它们之间放置了一些间距，以便您可以看到堆日志。

问题不在于 Volley 或 Retrofit，它很可能与大小或数据响应有关。如果您可以控制网络服务，您应该考虑使用分页将信息分解成更小的块。
响应非常大（超过 5 Mb），弱设备没有足够的 RAM 是有道理的。这是一项艰巨的工作，但如果服务器端由您管理，您应该将此响应拆分为几个响应。以块的形式发送它是行不通的，因为在处理响应之前您仍然必须将它们拼凑在一起，而且无论如何我认为您不应该在一个请求中解析这么多数据。
我也建议你看看这个答案，它会帮助你找到你检查的设备的限制：。
如果您可以控制服务器端，IMO，响应数据压缩是解决此类问题的另一种方法。
当然，在客户端，你必须先解压网络响应，然后再正常解析。
如果您的服务器应用程序是 ASP.NET Web API, for example, you can take a look at this ASP.NET Web API Compression 文档以供参考。我认为其他网络服务或某些网络服务器也支持压缩。
希望对您有所帮助！
好吧，我对 volley 了解不多，但我用 Jackson lib 处理过这种 json 响应。
检查这个答案Android: Parsing large JSON file
我认为 Jackson stream API 是正确的选择。
我正在使用 Volley 来管理我的应用程序。有时，当响应过大时，我会在没有太多 RAM 的设备上遇到 OOM。我不确定如何解决这个问题。我知道 Volley 将它的响应存储在内存中，但是我的应用程序非常依赖 Volley，以至于切换起来会很痛苦。我在使用 Retrofit 时也遇到了问题。我试过使用 JsonReader，但它似乎仍然会发生。我有一个与 Volley 一起使用的自定义请求。它 returns 一个 Gson JsonObject。这是我目前的代码，当响应数据长度返回 5511532 (5mb) 时，应用程序收到 OOM。
@Override
protected Response<T> parseNetworkResponse(NetworkResponse response) {
try {
String json = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
if (LOG_HEADERS) {
Log.d("GsonResponseHeaders", response.headers.toString());
}
if (LOG_JSON) {
Log.d("GsonRequestResponse", json);
}
return Response.success(gson.fromJson(json, clazz), HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JsonSyntaxException e) {
return Response.error(new ParseError(e));
} catch (OutOfMemoryError e) {
Log.d("ResponseLength", "-- " + response.data.length);
return Response.error(new ParseError(e));
}
}
编辑：
这是抛出 OOM 的示例响应。

大家好，我试着分开回答。它似乎有所帮助，但在 3-4 个请求之后它仍然给我一个 OOM。我相信这与排球有关。这是我对每个响应的 GC，它每次都在增长。请注意，堆每次都会增长。我在它们之间放置了一些间距，以便您可以看到堆日志。

问题不在于 Volley 或 Retrofit，它很可能与大小或数据响应有关。如果您可以控制网络服务，您应该考虑使用分页将信息分解成更小的块。
响应非常大（超过 5 Mb），弱设备没有足够的 RAM 是有道理的。这是一项艰巨的工作，但如果服务器端由您管理，您应该将此响应拆分为几个响应。以块的形式发送它是行不通的，因为在处理响应之前您仍然必须将它们拼凑在一起，而且无论如何我认为您不应该在一个请求中解析这么多数据。
我也建议你看看这个答案，它会帮助你找到你检查的设备的限制：。
如果您可以控制服务器端，IMO，响应数据压缩是解决此类问题的另一种方法。 当然，在客户端，你必须先解压网络响应，然后再正常解析。
如果您的服务器应用程序是 ASP.NET Web API, for example, you can take a look at this ASP.NET Web API Compression 文档以供参考。我认为其他网络服务或某些网络服务器也支持压缩。
希望对您有所帮助！
好吧，我对 volley 了解不多，但我用 Jackson lib 处理过这种 json 响应。
检查这个答案Android: Parsing large JSON file
我认为 Jackson stream API 是正确的选择。
