Increase Your VM Heap Size With VM Heap Tool
If you’re the sort of Android device owner who like to make a few mods to your phone such as giving more demanding applications more heap space, then take a look at VM Heap Tool.
A tweak designed by XDA forum member martino2k6, VM Heap Tool allows you to change the VM heap size, decreasing the frequency of garbage collection and giving apps more heap space.
The app lets you easily change the heap size without having to adb pull, edit and adb push files from and to your phone. Note that since VM Heap Tool modifies a variable that can affect the stability of the system, you should be careful how you use the tool.
Requires root access and busybox.
VM Heap Tool is available to download free from the Market, but for more information, visit the application thread.
