I posted a similar question some days ago without any success (http:// groups.google.com/group/android-developers/browse_thread/thread/ dddf6d5062dfb6b5/e970f0df5e229380?hl=en&lnk=gst&q=memory +dump#e970f0df5e229380). At least you have got the heap dump (that was the first step).
Have you tried with other memory analyzers like JProfiler (http:// www.ej-technologies.com/products/jprofiler/overview.html) or the SAP Memory Analyzer (now Eclipse Memory Analyzer) https://www.sdn.sap.com/irj/sdn/wiki?path=/display/Java/Java+Memory+Analysis ? Could you tell us where did you find exactly the 'runhat' shell function? I have found an old post from a Googler telling this: >> - In DDMS force a GC on your process, a couple of GCs on the system process, then another GC on your process, to get rid of any garbage left on the heap - Run the following command from a shell: adb shell kill -10 [pid of your application] - This will generate two files on the emulator, in /data/musci. One is called heap-dump-tmXXXXXX-pidXXX.hprof and the other one has the same name but with the extension .hprof-head. For instance, I have /data/misc/heap-dump-tm1213483064-pid4748.hprof and /data/misc/heap-dump-tm1213483064-pid4748.hprof-head - Download the two files on your computer with adb pull - Merge the two files by putting the .hrof-head at the beginning: cat heap-dump-tm1213483064-pid4748.hprof-head heap-dump-tm1213483064-pid4748.hprof > heap-profile.hprof - Open the resulting file with a tool that supports hprof files (JProfiler, hat, etc.) >> But I haven't had time to try it. Good luck! Jose Luis. On Nov 5, 8:12 pm, Disco Stu 010 <[EMAIL PROTECTED]> wrote: > Hello, > > While perusing the source code, came across a shell function that > envsetup.sh defines called "runhat".
