打开HPROF文件时出错:IOException:未知的HPROF版本 [英] error opening HPROF file: IOException: Unknown HPROF Version

问题描述

尝试使用Memory Analyzer打开HPROF文件(由Debug.dumpHprofData创建)时，出现以下异常:

I am getting the following exception when trying to open HPROF file (created by Debug.dumpHprofData) with Memory Analyzer:

java.io.IOException: Unknown HPROF Version (JAVA PROFILE 1.0.3)

我该如何解决?

推荐答案

从Android获取的hprof文件具有android特定格式.您应该将来自Android OS的hprof文件转换为标准hprof格式.为此，您可以使用位于AndroidSDK/tools/hprof-conv的hprof-conv工具.

The hprof file you get from Android has android specific format. You should convert hprof file take from Android OS into standard hprof format. For this you can use hprof-conv tool that is located at AndroidSDK/tools/hprof-conv.

例如:

hprof-conv android.hprof mat.hprof

然后在内存分析器中打开mat.hprof.

And then open mat.hprof in Memory Analyzer.

hprof-conv在某些软件包中可能位于AndroidSDK/platform-tools/下.

hprof-conv might be located under AndroidSDK/platform-tools/ in some bundles.
