How can i get and change the stack size (even for the main thread) of my Android application.
AFAIK -Xss can be used as a command line to change the main threads stacks size, if not using the command line the app framework will use the default size. In this case if you need more stack you will need to start a thread (using this ctor) to do the work.
The main thread stack size is set in the firmware and cannot be modified, short of modifying the firmware for your own phone. As Mr. Strong indicates, for threads you fork, you can set your own stack size.
