当我尝试在Verizon的4G/LTE上使用我的应用程序时,我收到了一些崩溃用户的报告.

查看堆栈跟踪,看起来Android的HttpClient.execute()实现正在抛出一个OOM.这仅发生在4G/LTE设备上,特别是HTC Thunderbolt,并且仅在4G/LTE上.WiFi,3G,UMTS都可以.也适用于Sprint的WiMax 4G工作正常.

两个问题:

• 什么是引起Android开发者注意的最佳方式？除了在http://code.google.com/p/android/issues上报告之外,还有哪些更好的选择？

• 关于如何解决这个问题的任何想法？我自己没有4G设备,我无法在模拟器中实现这一点,所以我需要在这里做一些有根据的猜测.我可以尝试在我的代码中捕获OOM并尝试清理并强制GC,但我不确定这是不是一个好主意.评论或其他建议？

这是我的代码正在做的事情:

    HttpParams params = this.getHttpParams(); // returns params
    ClientConnectionManager cm = new ThreadSafeClientConnManager(params, this.getHttpSchemeRegistry() );
    DefaultHttpClient httpClient = new DefaultHttpClient( cm, params );

    HttpResponse response = null;
    request = new HttpGet( url );

    try {

        response = httpClient.execute(request); // <-- OOM on 4G/LTE. OK otherwise
        int statusCode = response.getStatusLine().getStatusCode();
        Log.i("fetcher", "execute returned, http status " + statusCode );

    ...

这是崩溃的堆栈跟踪:

E/dalvikvm-heap(11639):2055696字节分配的内存不足.I/dalvikvm(11639):"Thread-16"prio = 5 tid = 9 RUNNABLE I/dalvikvm(11639):| group ="main"sCount = …

我有一个Android应用程序,JSONObject通过使用ByteArrayEntity对象发布为实体.这是它的样子:

post.setEntity(new ByteArrayEntity(entity.getBytes("UTF-8")));
result = client.execute(post, handler);

实体是一个String.处理程序是ResponseHandler<String>和客户端是一个HttpClient.这在模拟器和某些设备上运行良好.但是,有时我在执行时会得到OutOfMemoryError x10i(也称为XPERIA).

这是堆栈:

正如我所说,我只是将JSONObject发布为String.它最多可能是200个字符.怎么了？
