error opening HPROF file: IOException: Unknown HPROF Version

Question

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

java.io.IOException:          


        

Answer 1

If you are using Eclipse, just change the following:

1. Open Preferences (from the Window menu)
2. Navigate to Android->DDMS
3. Change the HPROF action to "Open in Eclipse"

Answer 2

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.

For example:

hprof-conv android.hprof mat.hprof

And then open mat.hprof in Memory Analyzer.

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

Answer 3

hprof-conv tool location got changed.

It is now located at AndroidSDK/platform-tools/hprof-conv
