Note: Scaling and alignment changes are saved until a device is reloaded. Whenever you reload a device (by double-
clicking it), the device returns to the default alignment and scaling settings defined in the profile.
Testing information for Flash
About the Memory panel
Use the Memory panel to monitor application memory use and to adjust various performance parameters in your
Flash file to achieve maximum performance. Static and Dynamic Heap values default to the respective sizes included
in the device profiles. For example, some devices do not have dynamic heap at all.
The Memory panel appears on the Emulator tab whenever you test a Flash application. A graph reflects static and
dynamic heap sizes with differently colored curves. The rightmost point in the curve reflects the current memory
usage (also expressed in KB below the curve). In addition, a process bar indicates the currently used memory as a
percentage of available memory.
You can use the Memory panel to make testing Flash content more effective. For example, if you have a large Flash
file that is too large to test on a specific device, change the static or dynamic memory to a larger number so the file
can be viewed. Return to Flash and optimize the file to reduce the size. Test the file again in Adobe Device Central,
reducing the static or dynamic memory to see if the file appears accurately. As you test the file, you can watch the
graph on the Memory panel to visually locate the large parts of the file. Another way to use the Memory panel is to
lower the dynamic heap number to simulate when other activities are taking place on a mobile device, such as a
phone call being received.

Change the static or dynamic heap size
When you change heap values, the changes are application-wide and not saved on a per-device basis. Resetting to
default sizes sets all heap sizes back to their respective defaults as specified in the profiles.
1
Open the Emulator tab by doing one of the following:
• From Adobe Device Central, select File > Open, navigate to a Flash SWF file, and double-click the file.
• In Flash, open a file and select Control > Test Movie.
On the Adobe Device Central Emulator tab, expand the Memory panel.
2
If testing your file requires a change in the actual heap size available on the device, click Edit.
3
4
Change the amount in the Static Heap or Dynamic Heap boxes and click OK.
The new amounts appear on the panel in red to show that they are customized and are no longer the correct, default
amounts for the selected device. To return to the default, accurate heap sizes for the selected device, click Reset. (This
resets both heap sizes to the defaults. To reset a single heap size, click Edit and then click the Reset icon next to the
respective heap size field.)
About device calibration
During the initial device emulation (that is, Emulate Performance is not checked), the Emulator tab runs with full
desktop or laptop speed. To accurately emulate device performance, calibrate each device on the Emulator tab.
