问题描述

尝试使用内存分析器打开 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:

推荐答案

您从 Android 获得的 hprof 文件具有 android 特定格式.您应该将从 Android 操作系统中获取的 hprof 文件转换为标准的 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 可能位于某些包中的 AndroidSDK/platform-tools/ 下.

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