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)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

How do I resolve this?

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.
