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)
at org.eclipse.mat.hprof.AbstractParser.readVersion(AbstractParser.java:124)

at org.eclipse.mat.ui.snapshot.ParseHeapDumpJob.run(ParseHeapDumpJob.java:56)

How do I resolve this?
回答1:
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.
回答2:
If you are using Eclipse, just change the following:
- Open Preferences (from the Window menu)
- Navigate to Android->DDMS
- Change the HPROF action to "Open in Eclipse"
回答3:
hprof-conv tool location got changed.
It is now located at AndroidSDK/platform-tools/hprof-conv
