Hello. I have been trying to use traceview for profiling my Android
app. So far I have gotten it to work on very small parts of the
program. If I use it for bigger chunks it creates too much information
(.trace file is too large) and I get an OutOfMemory (heap memory)
error from the java compiler. I tried some tricks with setting higher
min and max heap memory values but no luck.
If anyone has used traceview with similar effects before I would
highly appreciate any tips you may have.
Here are the details. First I am reproducing the error message:
$ traceview.bat tmp.trace
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
at com.android.traceview.TimeLineView.setData
(TimeLineView.java:433)
at com.android.traceview.TimeLineView.<init>(TimeLineView.java:
316)
at com.android.traceview.MainWindow.createContents
(MainWindow.java:93)
at org.eclipse.jface.window.Window.create(Window.java:426)
at org.eclipse.jface.window.Window.open(Window.java:785)
at com.android.traceview.MainWindow.run(MainWindow.java:58)
at com.android.traceview.MainWindow.main(MainWindow.java:190)
On windows traceview works from a batch file that is reproduced below.
The last line is where I am mucking with the memory settings. That
does not seem to affect the behavior though. The parameters-- -XX:
+HeapDumpOnOutOfMemoryError -Xms2g -Xmx2g-- have been added by me ...
again they have no effect. Maybe because they should be used when
generating the .jar file itself?
