ProGuard不会与okhttp玩得很好,我会继续收到以下警告:

这些是我的okhttp和改造的proguard设置:
-dontwarn rx.**
-dontwarn okio.**
-dontwarn com.squareup.okhttp.*
-dontwarn retrofit.appengine.UrlFetchClient
-keep class …在调整大位图的大小以便更快地将图像上传到服务器时,我偶尔会遇到OutOfMemoryErrors.为了防止这种情况,我计算了所需的内存量,并在尝试缩放图像之前检查它是否超过Runtime.getRuntime().maxMemory().
但是,即使图像应该很容易放在堆上,我仍会遇到OOM错误.
仿真设备(Galaxy SII API 16)使用上述方法为我提供了67108864字节的最大内存.
在下面的代码片段中,堆大小为43975K,并且仅使用该内存的<15K.对于我的~31K分配,堆应该自动增长到大约45K,这仍然不接近64 MiB的最大大小.但正如您所看到的,dalvik vm不会扩展堆,而是耗尽内存.

我想知道这是否会在真实设备上发生,或者这可能是一个genymotion错误.
堆保证扩展到maxMemory()吗？JavaDoc for Runtime.getRuntime().freeMemory()表示它"可能"扩展,无论这意味着什么.
我只需要一种可靠的方法来计算我可以使用的内存量,这就是我的方法,如果我错了请纠正我:
long maxMemory = Runtime.getRuntime().maxMemory();
long usedMemory = Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory();
long availableMemory = maxMemory - usedMemory;
此调用导致OutOfMemoryError:
