Hi fadden,
Nice to talk with you again.
I have a question and would like to ask you.
When I running Dalvik, some times I meet the following exception:
dalvik/vm/interp/InterpCore.h:2533 Stack overflow on method call
(top=0x863f52c0 end=0x863b54c0 newB
ot=0x863b51f0 size=262144 'nativeGetStackTrace')
dalvik/vm/interp/Stack.c:1043 Stack overflow, expanding (0x863b54c0 to
0x863b52c0)
dalvik/vm/interp/Stack.c:1085 Shrank stack (to 0x863b54c0, curFrame is
0x863f4f70)
