To some extent, they both are. If you initiate an HPROF dump by sending a signal to the process, it ends up in /data/misc. This is not generally available to end users, because (a) you can't send the signal unless you're root, and (b) / data/misc isn't world-writable by default. The android.os.Debug.dumpHprofData() call takes the filename as an argument, and mentions "/sdcard/dump.hprof" as a nice place to put it. Passing a null filename earns you an exception, so it's not really accurate to say that it's the default. More like a recommendation. If you use the hprof-dump button in DDMS, it will go onto /sdcard with an app-specific filename. In a future release of the system it won't hit the filesystem at all when you use DDMS, which is very convenient since otherwise the target app must have the "external storage" permission to write the dump there.
